Underground space is a resource of great potential benefit which has been exploited in different parts of the world for thousands of years. While some cultures literally have lived an underground existence, others have yet to realize any of the benefits of subsurface use. This article is concerned with the use of underground space for architectural applica tion, i.e., designed for the purpose of human habitation or occupance for the tasks of daily life. Historical underground applications usually revolve around a few primary themes, which were the subject of Part I. The major emphasis of interest in the subsurface has shifted several times in the past few decades, during which a rich assortment of building types and forms has emerged. Part II examines these modern forms and functions with the intention of summarizing our current state of practice.
PART II: FORMS AND FUNCTIONS IN THE MODERN WORLD
Introduction
PART I of this article described the heritage of
undergound space use and identified several major
themes of subsurface development evident through
out history in various cultures of the world. These
themes consist of climatic, ·defensive, and resource
related responses to the local environment, and of
ceremonial or experientially-related uses of the sub
surface derived from its symbolic and physical
attributes.
Also in Part I, a distinction was made between
types of underground development which are ex
cavated in self -supporting media and those which
are built up through the practice known as cut-and
cover construction. This first technique has been
described as lithotecture, which generally assumes
some method of subsurface excavation (such as
mining or tunneling) in geologic strata. The latter
process has been termed terratecture, and it applies
specifically to building construction in soil environ
ments.*
*These descriptions follow directly from geog
rapher Truman Stauffer's definitions of "terraspace" and "lithospace" submitted to the symposium on the "Development and Utilization of Underground Space," Kansas City, 1975 (Department of Geo sciences, University of Missouri, Kansas City). "Lithotecture" and "terratecture" have appeared previously in the literature, and are used here in agreement with both their earlier use as well as Stauffer's.
Considering the scope of conventional profes
sional practice, near-surface terratectural building is
likely to be the only form of subsurface construc
tion within the capability or interest of most archi
tectural offices. It is not surprising then that the
overwhelming majority of modern instances of
underground architectural application fall into this
category; for this reason, Part II will deal exclusive
ly with terratectural alternatives in architectural
design.
The Relationship Between Fonn and Function
The relationship between form and function has
always been at issue in the development of a theory
or an aesthetic of modern architecture. In possibly
no other mode of architectural design is this rela
tionship - at least regarding the typology of form
- more critical to the satisfactory performance of a
building than in subsurface applications.
Underground designs, for instance, may call into
question the utility and psychological value of
features as ordinary as windows, sunlight, on-grade
access, and visual identity of the building as an
object. These elements need not be sacrificed in
terratectural alternatives, but the implications are
clear: a fully subsurface chamber cannot have
exterior windows, nor will it have a highly visible
form. In building functions where natural light and
views are highly regarded (such as residences or
offices), or where visibility and curb appeal are
essential economic considerations (shops, restau
rants , etc.), such a form is ill-suited to the building
program. On the other hand, many building func-

tions already are well adapted to subsurface environ
ments* , and realize little benefit from being on the
surface where they are subjected to wind, rain, sun,
and seasonal temperature fluctuations. Examples in
clude warehouses, telephone switching facilities ,
electric substations, parking garages, and assembly
plants. If the aspect of imageability is discounted ,
this list can be greatly expanded to include uses
such as theatres and auditoria , galleries and
museums, night clubs , supermarkets, department
stores , recording studios, and a host of other both
common and esoteric applications. On the other
hand , terratectural buildings are not necessarily
formless or image!ess, as the following classification
chart illustrates.
water readily , balance on-site cuts and fills , and are
well adapted for use in areas of high ground water
level. Earth berms themselves may be used as archi
tectural elements (to shape space), as visual and
acoustical barriers , and/ or as interesting play sur
faces.
Subgrade structures permit continuity of the
grade level, and have been popularly employed
where site and building programs demand a low
profile or a "non-building" architectural solution.
One of the great virtues of sub-grade structures is
this invisibility and the non-disruptive integration
into existing contexts which it enables.
Atriums and courtyards are frequently incor
porated into subgrade designs to provide access , to
create outdoor rooms, and to introduce natural light A TAXONOMY OF TER RATECTURAL TYPES

(This chart has been modified from an earlier version which first appeared in the author's thesis, "The Architectural Use of Underground
Space: Issues arid Applications").
This simple taxonomy suggests the diversity of
physical options available in earth-covered construc
tion. The variety of surface-to-subsurface relation
ships which characterize the types depicted here
suggest that caution be exercised in generalizing
about the "intrinsic" qualities of underground struc
tures. The two abstracted types presented - berm
and subgrade - are simply points of departure for
modification, combination , and compromise to suit
individual sites and requirements. Nonetheless , some
generalizations are appropriate to these two types in
their pure forms.
Berm-type structures may be molded into the
landscape or may be used to create bold , simple
forms. They are easily shaped to facilitate on-grade
access and window exposures, particularly when
used in conjunction with retaining walls. Berms shed
*These functions are said to be para-geotectural,
or "as underground." Para-geotectural qualities us ually are assumed to include windowlessness, which is not, however , a universal characteristic of earth covered stru ctures. Para-geotectural functions may best be described as those "which might as well be underground."
Windowlessness
Windowlessness cannot be regarded as an inherent
characteristic of the subsurface, yet it always will be
an inescapable issue in the design of terratectural
alternatives. Although fenestration is available to
many underground building forms, the area and
orientation of windows always will be somewhat
limited and a determining factor in the arrangement,
or zoning, of interior functions.
The subject of windowlessness itself has generated
a great deal of debate during the past two decades ,
but it remains clouded by much emotionalism and
little empirical or psychological study .* The usual
effect of eliminating windows is to internalize the
environment, i.e ., to focus it inward by removing
outside stimuli which are unrelated to the task at
hand. Some architects have been quick to seize the
advantage of this feature , especially in the design of
learning environments where exterior distractions
(traffic , playground activity , lawn mowing) interrupt
students' concentration while challenging teach
ers' disciplinary authority.
The idea of windowless or underground schools
has been met with apprehension and claims of
"unnaturalness" on the part of parents. Performance
studies assessing students' achievement and behavior,
teacher attitudes, and post facto community opin
ion in such situations , however , have shown them to
be at least as effective as neighboring control
schools; there is some additional evidence to suggest
greater satisfaction and benefit from windowless
classrooms than from ordinary, windowed , surface
school rooms.

from the National Bureau of Standards, #NBS Building Sci. Series 70.

139 The Architectural Underground
Less controversial uses of windowless environ
ments are those in which people spend little time ,
and where windows jeopardize or conflict with the
performance of the function being housed. Exam
ples include photographic lighting studios, dark
rooms, museum storage, refrigerated warehouses,
planetariums, mushroom farms, and the "para
geotectural" applications previously discussed.
For functions in which natural light and views are
highly desirable, expected, or may connote status
(as in the top floors of an office building), the
absence of windows will usually result in some form
of occupant discontent. Dissatisfaction caused by
what one may perceive as substandard conditions
ultimately will fault the overall performance of a
structure, regardless of extra-functional benefits
such as energy conservation and landscape preserva
tion. Designers of underground environments have
compensated for this in a number of ways. One
method has been to provide generous spatial accom
modations - high ceilings, wide corridors, and in
ternal windows (vision panels) to visually link
offices, lobbies, and reception areas. Another
method of spatial compensation is to group small
"aedicular" spaces (e.g., offices) around a grand
central space , such as a multi-level lobby or atrium .
Lighting compensation also may be introduced with
bright, cheerful colors on the walls augmenting
carefully selected task and "complexion" lighting.
Highly uniform environments inevitably lead to
boredom and dissatisfaction, and should be avoided.
Surrogate windows and simulation devices are
cosmetic approaches to earth-integrated design. The
perceived need for them ·reveals the imposition of
underground location on a function ill-suited to the
subsurface , a poorly-conceived architectural solu
tion , and/or deficient design of the interior. In the
final analysis , surrogates and simulation techniques
may offer psychic comfort to some, but their
ultimate success depends on one 's environmental
sensitivity and willingness to be assuaged by devisive
artificiality .
Surface-Interfacing Solutions
In a building program where windows are
germ ane to the building's activities, the concern for
occupant satisfaction may preclude a fully window
less design. Surface-interfacing solutions are ideal for
such situations, particularly where major portions of
the building can tolerate or benefit from window
lessness (as in the case of libraries, e.g.). With
judicious zoning of internal functions , heavily
peopled areas may enjoy the presence of windows ,
while services, circulation , and mechanical facilities
are relegated to the windowless interior. Surface
interfacing forms have proved to be the most popu
lar and versatile of terratectural alternatives; their
variety of shapes , sizes, and applications will be
discussed in the remainder of this paper.
Forms and Functions: Modern Themes of Sub
surface Use
As in historical cases of underground use , several
major themes underlie the development of sub
surface alternatives in modern practice. Moreover ,
these themes reflect the bases of the troglodytic
tradition: energy-related interest in the underground
is relatively new, yet it closely parallels the climatic
benefits realized long ago by far less sophisticated
cultures. Conservation-oriented consideration of sub
surface buildings is but a new interpretation of
environmental resource allocation; aesthetic argu
ments for earth-covered buildings continue a formal
interest in earth-architecture as old as building itself.
Similarly, bomb-shelter solutions echo the defensive
advantages of the past , and the experiential quali
ties of penetrating the subsurface surely are as real
today as in pre-history .
The majority of modern underground buildings
embody one or more of these themes , but the most
prevalent single determinant in decisions to go
under derive from peculiar site circumstances. This
will be illustrated in the following discussions which
relate how program , site , and taxonomic form have
come together to create successful earth-covered
structures.
Extraordinary Site Circumstances
The Lake Worth Junior High School near Fort
Worth, Texas , exemplifies an extreme, but not
uncommon , locational problem that was resolved
satisfactorily with a fully subgrade, windowless
building: Situated directly in line with the flight
path of nearby Carswell Air Force ·Base , existing
on-site classrooms experienced the incessant jet
whine of approaching B-52 bombers. Architect
Preston Geren 's response to the inhospitable acous
tical environment was to build the entire new junior
high school underground . Two other aspects of the
design (see illustration) are noteworthy : the con
crete slab "roof" of the main building functions as
a playground , while the school's cafeteria has been
constructed beneath Telephone Road , which serves
the school.
A further advantage of the subsurface location is
the protection it offers in the event of aircraft
accidents and the fire hazard associated with near
airport sites. Perhaps of greates t significance is the
fact that students and faculty alike are enthusiastic
about Lake Worth Junior High School , now in its
eleventh year of operation .
An even more unique circumstance is found at
the Champaign /Urbana campus of the University of
Illinois. There , architect Ambrose Richardson was
faced with building a new undergraduate library on

a site immediately to the west of the nation's oldest
agricultural test plot. The building program pro
hibited a structure tall enough to cast afternoon
shadows on the test field , so Richardson designed
his two-story facility to sit under - rather than on
- the site. The result is an open pedestrian plaza
where a building might have stood, with the addi
tional benefit that the undergraduate library links
directly with the basement of the adjoining graduate
library. The building plan is a "square doughnut,"
with both levels of stacks surrounding a two-story
deep central courtyard.
Physical, Topographic Site Conditions
Often topographic and other existing site condi
tions combine to provide both an opportunity and
sufficient reason to select a subsurface alternative. A
splendid site overlooking the Delaware River in an
historical district of Bristol , Pa., presented such an
opportunity when architects Carroll , Grisdale, and
Van Allen (now J. Ray Carroll, Jr. and Partners)
were commissioned to design the Margaret R.
Grundy Memorial Library.

pleasant lawns at both upper and lower levels. The
scale and residential character of the neighborhood
is preserved by reducing the visible bulk of the
library building. Only a small entry pavilion occurs
on the surface; the openness of the remaining site
serves as an effective foil for the adjacent Grundy
House, now a local museum. The entire southern
side of the building is a fully-windowed facade,
providing direct views of the river from offices and
reading areas of the library .
The Grundy Library is an understated testimony
to sensitive site planning. It fully realizes the beauty
of a superb location and responds graciously to the
quiet historical surroundings in which it resides.
Sloping sites are ready opportunities for terra
tectural schemes, so it is no accident that many
designers envision buildings tucked into the con
tours of a hillside . An underlying concern of archi
tect Don Metz was to preserve the existing character
of his house site in rural Lyme, New Hampshire. He
achieved this by recessing the structure into the
slope, covering the roof with sod, and letting nature
reclaim the site. In spite of being underground ,
Metz's Winston House enjoys a southern exposure
and 50-mile distant views. The earthen surroundings
of this modern dugout mitigate the severe cold New
Hampshire climate; its solar orientation captures the
low winter sun while an overhang ensures summer
shading. Metz has been so satisfied with this mode
of building that he has begun a second earth
covered house on a nearby site. Dugout #2 is a
curvilinear, two-level plan that more closely resem
bles type A4 in the foregoing taxonomy than the
single-elevation dugout form of Winston House.
Both ate superbly integrated into the natural envi
ronment, yet capture the expected visual amenities
of more conventional surface designs.
Aesthetics and Site Planning: Non-Objective Archi
tecture?
Of all the site-circumstantial conditions which
have led to underground building designs, probably
none is better represented than those cases in which
a building is required , but where its physical pres
ence is undesirable. Two situations are especially
common: The first comprises additions to existing
buildings, the second involves building expansions
which encroach on valuable open space. Both in
stances are typically urban in context, and are
frequently encountered in center -city areas and on
university campuses. Historic preservation is often a
key issue in these circumstances , but the non
existent form of sub grade structures is an ideal
complement to contemporary urban focal points as
well.
Architect Victor Prus has described this ap
proach as an "architecture of little presence." His
design for the Grand Theatre of Quebec complex
incorporates a bi-level subgrade conservatory that
succinctly illustrates this philosophy. The open sur
face of the conservatory site emphasizes the volume
of the major edifice, with which it is integrated at
basement levels. Furthermore, the busy character of
the surface of the site conflicted with the quieter
demands of class and practice rooms:
"The site itself is very small and fairly noisy as one of the
bordering streets has become a major vehicular artery.
This circumstance necessitated extremely compact plan
ning. That and the hustle and bustle of the downtown
traffic caused me to organize the conservatory on two
underground levels around a landscaped court sunken
below street level. A forest of black spruce further
protects it on three sides while on the fourth there rises
the one simple volume of precast concrete, housing on
this side entrances to conservatory, its library and dis
cotheque, and on the other side, entrances to theatres,
lobby and foyers and, of course, the two theatres stacked
one on top of the other."*
A similar formal relationship is found between
the monumental Jefferson Memorial in St. Louis,
Missouri, and the museum addition, designed by
Sverdrup & Parcel and Associates. The Jefferson
Memorial is a regional museum and contains the
offices of the Missouri Historical Society. With the
increasing need for additional gallery space, an
architectural design was sought which would not
disrupt the memorial's classic Beaux Art facade. The
award-winning solution locates the new annex
below-grade as an extension of the existing build
ing's basement galleries. The core of the addition is
a recessed courtyard exhibition space. It serves
multiple functions of admitting daylight, providing a
fire exit, and acting as an orien tational device for
visitors to the earth-covered galleries.
The Walnut Hill Methodist Church Youth Center
in Dallas, Texas, illustrates the "non-building" aes
thetic applied to still another highly-visible site of
limited area. Architects Brown , Brown, and Asso
ciates of Dallas were commissioned by the church
to design accommodations for recreation, study, and
social activities. The only available location, how
ever, was on the property's front lawn. The archi
tects ' analysis suggested that the structure should be
built under the grassy site where it would not
obstruct the sanctuary's street facade. Although
initially met with mixed reaction, the subgrade
scheme offered another amenity that assured its
approval: it allowed the architects to connect the
new structure to the basement recreation/kitchen
complex of the existing building, thereby averting
the anticipated need for additional major kitchen
facilities. The underground youth center is an ideal
solution to a particularly sensitive set of program
matic issues; moreover , it is possibly the only fully

satisfactory resolution of all design issues confront
ing the architects.
Other "invisible buildings" that respond to aes
thetic criteria include architect Philip Jo hnson's own
well-publicized art gallery on the grounds of his
estate in New Caanan, Connecticut. Faced with the
need for space to exhibit and protect his collection,
Johnson created a landscape-conforming bermed
bunker in lieu of a building as a perceptible object.
He enjoys the gallery's psychological play on visi
tors' anticipations:
"... going into a building that isn't there, they get that
feeling of "where are we going?" Since every room is
about 10 times bigger than they expect, there's a positive
element of surprise and romance. Caves are probably an
atavism of some kind; people enjoy being enclosed. "*8,

Still another well known - and overlooked -
underground facility is the Visitor Center at the
Jefferson National Expansion Memorial in St. Louis,
Missouri. Nearly 43,000 square feet of museum,
theatre, and lobby space was constructed during the
early 1960's in conjunction with Eero Saarinen's

front. Most of this area to date has been unde-

veloped and inaccessible to the public; it will soon
be opened as part of the Bicentennial celebration,
and will house the National Park Service's Museum

The grass-covered Visitor Center currently pro
vides access to the Arch's internal transportation
system, which is entered underground in the legs of
the structure. Burying all supporting facilities be
neath the surface enabled Saarinen to spring the
mammoth stainless steel sculpture from an unclut
tered surface - seemingly from the earth itself.
Underground Campus Planning
Underground campus facilities have become com
mon in recent years, since most colleges have
limited physical plants and expanding spatial needs.
Locating new accommodations subgrade permits
architects to build near existing st ructures without
disrupting the spatial relationships that are a virtue
and a delight of well-planned campuses. Examples
of such facilities typically include libraries, student
centers, and book stores.
Illustrative of campus underground development
is the addition to the existing University Center of
the University of Houston, in Houston, Texas. The
plaza-rooted solution was designed by the office of
Goleman and Rolfe, Architects. Mr. Coulson Tough,
Vice-President of Facilities Planning and Operations
at the University, is to be given credit for estab
lishing the program requirement that the new struc
tur e be located underground.
The subsurface solution preserves open space on
campus and seizes the opportunity to extend an
existing subgrade level of the adjacent University
Center. A cluster of skylights creates a focal point
in the underground lounge , which is flanked by a
variety of offices , meeting rooms, and small audi
toria . It may seem unusual that an underground
facility can incorporate a major pedestrian route,
but the University of Houston Student Center is
well-integrated into the campus circulation system.
It is fitting that this carefully studied , understated
design has become a major center of activity at the
University of Houston.
Developing campus underground space is a wise
endeavor in itself; the increased density resulting
from three-dimensional planning makes a university
more efficient by area, more stimulating through
activity, and more convenient in terms of pedestrian
mobility. The urban mini-system of the university
no doubt holds lessons for larger urban contexts as
well, although few cities have as practiceable an
open space policy as colleges have license to govern.
Nonetheless, campus-like subsurface development
could become an important tool for optimizing the
usefulness of an urban locale, while simultaneously
functioning as an aid for preservation of open space
and historic areas.
Not all structures that are located underground in
the name of open space planning are a product of
existing circumstances. When the Vineen t Kling
Partnership created the master plan for Monsanto
Company's world headquarters, it was determined
that the company cafeteria should be situated to
serve all office buildings of the corporate campus.
The necessary centrality of the location itself con
flicted with the open space plan, so the cafeteria
was designed to occupy the chosen site subsurface.
Subgrade location here was not an accident of
existing circumstances, for another feature of the
master plan included a network of tunnel connec
tions between buildings. These afford easy and
weatherproof communication pathways around the
campus, and several tunnels converge on the
mezzanine level of the spacious cafeteria building.
That the cafeteria is in fact covered by up to four
feet of earth, grass, and planting seems implausible
from within: deep , bright, light wells flank the
structure on three sides, and a bi-level skylight
illuminates both the mezzanine lobby and the serv
ing line below. An impressive structure in every
respect, the Monsanto cafeteria is an obvious credit
to an enlightened owner and its imaginative and
facile archi teet.
Environmental Applications
The remaining major interest in underground
structures may be loosely grouped under environ
mental concerns, and relates to both nature and
energy conservation. To have any significant impact
on a regional or national scale, earth-covered struc
tures must enjoy widespread application and popu
lar acceptance. Large scale use , however , is likely to
be impeded by sluggish lending and zoning policies ,
although these problems are already being
addressed.
Nonetheless, individual owners can benefit from
the environmental underground approach on their
own sites, regardless of the scale of neighboring
application. Natural returns will take the form of
increased usable land area, and energy benefits will
be realized in terms of economic savings. Some
models of small-lot underground buildings have al
ready been well-published, including Malcolm Wells'
own architectural office in Cherry Hill, New Jersey ,
and architect John E. Barnard, Jr.'s demonstration
"Ecology House" in Marston Mills, Mass. Wells has
expressed the sentiment, "if you can't improve the
site, don't build at all." This is a radical manifesto
in the context of modern America's building prac
tice, but one which may soon enough become
necessary. The following three buildings are very

The geometry of Aida's design may seem any
thing but natural to American readers , but his
response is supplemented by an historical theme as
well:
"! shall strive to reinstate the heritage of forms that
mankind has built up over the ages. In fact, it may be a
return to these forms will become a matter of paramount
significance."*

vide the school children with a kind of spatial
experience which Aida considered enriching.
Near Austin, Texas, the native grass is beginning
to grow back over one of the most intriguing
structures yet to emerge from the modern under
ground. Coffee and Crier, Architects and Planners
have designed a courtyard house reminiscent of the
Roman atrium plan (discussed in Part I of this
article) and the Pakistani houses familiar to their
client, a language professor at the University of
Texas. The semi-bermed form alone is superbly
adapted to the Texas site, where tornadoes have
twice damaged a nearby house. But it is the under
ground design coupled with solar energy that makes
this residence especially distinctive.
A 12' x 20' solar collector assembly is located on
a mound detached from and facing the house. A
1000 gallon storage tank buried next to the en
trance reserves a supply of space heat and pre
heating for domestic hot water. The atrium serves as
an entry, focal point , and hallway for the dwelling.
A water fountain and pool in the court area will
cool and humidify the space. Solar cooling was
considered for the house , but the cooling demand is

so low that even the smallest available solar unit is
exceedingly oversized and would be inefficient for
general use. The Bordie House no doubt can have a
very beneficial influence on the use of terratectural
alternatives; its immediate benefits will be realized
most welcomely by the imaginative Bordie family.

include natural ventilation by exhausting hot air
through roof vents and introducing cooler air below
grade by multi-purpose "windowscopes." A light
siphon acts as a highly-sophisticated skylight to
provide daylight to the subterranean level. The solar
collector scheme is based on the modular organiza
tion of the house, and solar storage is contained in
an accessible location on the roof.
The somewhat futuristic look of Undersol itself
suggests the richness of potential form that is
inheren t in underground alternatives. In contrast to
the frequent use of dugout and atrium types of
development, Undersol is a stimulative reminder
that we have yet barely scratched the surface of
terra tectural form.
CONCLUSION
The many examples of underground architecture
presented in these two articles clearly demonstrate a
long heritage and a successful active present of
architectural subsurface space development. A
variety of terratectural forms ranging from fully
subgrade protective structures to a host of well
windowed surface-interfacing types are in current
use. The broad spectrum of these types offer archi
tectural environments fully appropriate to almost all
conceivable building programs. With the increasing
congestion of urban and formerly rural land, with
the quest to preserve environmental quality and the
need for energy conservation, and with the re
emerging interest in architectural form, terratectural

alternatives are destined to have a bright and enter
prising future.
The most exiciting aspect of the future of under
ground architecture is that the necessary technology
already exists. The subsurface offers a promise - an
alternative in tune with the times and replete with a
richness of heritage , meaning, form, and practicality.
It is time that earth-covered buildings are recognized
as a truly 20th-Century architecture, and one of the
most vital alternatives currently available to us.
