This project proposes a performing artcenter in Chattanooga, Tennessee, a 170--year old industrial city. As part of the cityrevitalization, the design seeks to build upa “stage”, and create a piece of edge atthe city’s northern boundary. Two foldedbands, one made of skeletal steel and sur-faced with copper connecting the river andthe mountainous landscape beyond withthe city, the other made of reinforced con-crete folded to form a spatial intersectionhousing a series of activities: performing,spectating, and exhibiting. A curved metalscreened circulation wall opens at the bot-tom to allow the copper band to pass asan entrance into the lobby to develop itsfolded intersection. Through it, an indus-trial stack in the middle of the site is iso-lated from busy city, and anchored with thebuilding as a monument. Along the westside, an additional element characterizedas the education box hovers over theground, with unobstructed views of theriver and the old steel bridge on one end,and the green hill on the other.

Chattanooga, a city insoutheastern Tennessee,and the seat of HamiltonCounty, is a port on theTennessee River, nearthe Georgia border.Bridges span the river tolink the two sections of thecity, which is almostsurrounded by mountainsas the center of an areawith many scenicattractions, includingLookout Mountain, RubyFalls, and RaccoonMountain Caverns. Itsgeneral climate is hot andhumid during the summer,cool in the winter.

The city’s focus on development thatmeets the needs of futuregenerations has earnedChattanooga world-wide recognition.In the 1990s, Chattanoogaattempted to build its economyaround environmental principles, andtoday the city’s air is again clean.Tennessee Riverpark Master Plan,created in the mid-1980s, has beenthe outline for the ongoingrevitalization of the 35 km (22 mi)riverfront.
The community now known asChattanooga was laid out in 1838and grew as a river port; it wasincorporated as a city in 1839.After the Civil War, Chattanoogawas built as an industry base. By1880, it had become one of theleading manufacturing centers inthe nation. And, by 1950 the cityhad the highest number ofmanufacturing employees percapita of any city in the country.
The city also had a growing pollutionproblem, which was endangering itscitizens...and killing its downtown.
Between 1990 and 2001 over sixhundred million dollars were spentin improving its urban area. Thecity has received nationalrecognition for the renaissance ofits beautiful downtown.
HISTORY

SOUTH WESTEAST
Chestnut street
LOCAL CONTEXT
The site of the Experimen-tal Performing Arts Centerbuilding is located at the in-tersection of West 2ndStreet and ChestnutStreet, at the edge ofdowntown Chattanooga. Itlies between the Tennes-see Aquarium and theIMAX 3D Theater, facingthe Tennessee river. TheArts Center replaces exist-ing surface parking on thesite.

NORTHWEST EAST
CONTEXT OF THE SITE
THE SITE LOOKING FROM CHESTNUT
The site offers an opportunityto contribute to the develop-ment of downtown’s edge andthe connection of downtownwith the river and mountainsbeyond. The program requiresthat an existing industrial stackin the middle of the site mustbe incorporated into the designsolution as a monument tomany manufacturing facilitiesthat once line the riverfront andprovided an economic base forChattanooga.What is the proper relationshipbetween the industrial stackand the building, and how tocreate the relationship is a cru-cial point in the building design.
13
site
Buildings are approaching the city bound-ary in lines stretching from the center ofdowntown. Matching with the urban con-text became a starting point of the con-cept of the design, extending the lines to-wards the river and the mountains.

Idea I:The stack is a fragment of the city’s indus-trial history. It penetrates the building inthe middle leading light into inside space.The building leaves a public green plazaunderneath, which faces the riverfront areaand frames the scenery on the oppositeside of the river. But this scheme was aban-doned because the building would block theview to the stack from the public urbanspaces, and the relationship between themcouldn’t be articulated.
UNDERSTANDING THE RELATIONSHIP- Initial ideas
20
Idea II:
The building withdraws from thestack, adjacent to West 2nd street, andmakes an alignment to the existingIMAX 3D Theater. The inclined wallfollows the city planning strategy, andmakes a plaza along Chestnut Streetwhich leads people into the building,and to the riverfront. Half of the build-ing is floating, leaving a shadedground underneath. This public spacemerges with the riverfront park. Thestack is embedded into the greenplaza, as a sculpture. Part ofbuilding’s geometry responds to thedirection of scenic views. The roof andcolumns frame the picturesque land-scape beyond. But this idea doesn’tcreate a strong relationship betweenthe industrial stack and the building.

THE COPPER BANDTHE CONCRETE BANDTHE CURVED WALLTHE EDUCATION BOXTHE THEATER
35
The copper band begins as thetheater roof, folds and drops as aninclined wall, and folds again to levelas a walkable man-made floor thatreaches the edge of the river.Conceptually it connects the naturalsetting of Riverfront Park and themountains beyond with the denserurban environment. Underneath thisvast, horizontal copper deck, arrivaland parking are joined with a grandaccess toward the complex markedby the existing smoke stack.
THE COPPER BAND
37
The copper roof extends its edge out pastthe wall above the street, creating a cov-ered urban space.
39
The copper flows downas a inclined wall, andfolds as a man-madefloor. Between the walland floor, the copperforms a groove, a con-ceptual divide, housinglights which shine onthe inclined wall.

Continuity at detail
40
The copper band flows out as a floorpassing through the gate-like open-ing at the bottom of the curved wall.The material continuity suggests aliteral coherence between inside andoutside.
Along two sides, the copper bandfolds up to an eye-level boundary.The two boundaries constrict theview, and present the beautifulmountainscape. They also exhibitinformation about events in the cityand its development on their sur-face.
41
At the end, the deck steps down into a balcony exposing the sharp horizontaldeck line without boundary. Upon arrival on the balcony, one realizes the riverdirectly below. From there, it is possible to enjoy the boating and other activityon the river.
42
DEVELOPMENT OF THE COPPER BAND
Underneath the copper roof andwall, the space frame structurespans 90 feet to contain the audito-rium and its workshop. The spaceframe system is composed of fourprimary structural elements and asecondary system of connectingelements.
43
Perpendicular to the copper band,the concrete band begins as afloating roof over the entrance hall.It folds and becomes a wall andfinally extends to the west as a floortoward the other institutionalbuildings. Along its side a plaza isdefined with setbacks from ChestnutStreet and Second Street. From thisplaza a long entrance ramp leads tothe lobby.
THE CONCRETE BAND
45
The concrete band is folded up toconstruct an intersection with cop-per band. Natural light, insertedinto the intersection space throughthe gap between the two bands,emphasizes the two bands.

LOBBY BOX IN THE INTERSECTION SPACE
Underneath the concrete bandis a hanging glass box, inwhich a small box-office andthe lobby are located. The pri-mary structure of the box issteel studs accompanied by aglass structure, one end ofwhich is hung by cables, whilethe other is held by the curvedwall. Two bridges lead peoplefrom the lobby into the theaterpuncturing the inclined copperband.

MAKING THE GLASS BOX
52
The glass structureand hanging cablecreate the maximumtransparency. Itmakes the boundaryof the intersectionspace clear.
53
The curved circulation wall is aboundary membrane that sepa-rates the stack from the busy cityto promote serenity. At the sametime it provides a function asproscenium screen with its curvedgeometry as a response to thestack.
THE CURVED CIRCULATION WALL
55
The curved metal screened wall anchorsthe chimney with a terrace balcony. Thewall provides an opportunity to read thechimney at different height levels, fromdeck floor, bridge, education box and ter-race balcony.
56
The covered wall and the horizontal cop-per deck form a quiet space which is com-patible with the monument --- the stack.This space also provides a place for theout-air performing activities.
57
The one-directional long stair leadspeople from the underground parkingspace level and deck floor level to thelobby, inside balcony, and the high ter-race. It creates a strong space inside thewall.

THE EDUCATION BOX
The education space is a floating hollow boxopening on two ends, linking the views point-ing to the river and the old steel bridge on oneend, and the green hill in the city on the other.It hovers over the ground along the west sideof the building, and defines the west boundaryof the intersection space. The floating boxmakes a place underneath. The transparencyof the box invites the natural environment intothe public space.
61
The hollow box is occu-pied by the dance andchoral rehearsalrooms, a design centerand class rooms. It isdetached from otherspart of the building sig-naling its different char-acter. This requires arelatively quiet and pri-vate place away frompublic spaces.Perforated metal pan-els cover the box fromopaque to translucent.
64

View from the Education Box toward the Entrance Hall
The box opens at the middle of the wall, which faces the public space at theintersection. The opening allows people to walk from the lobby, and pro-vides access for communication between the space in the box and theintersection space.
66
The theater space itself is accessed via thelobby bridges puncturing the inclined cop-per band. The copper band, supported bythe space frame mega structure, sheltersthe stage and support rooms. A secondaryceiling suspended from the copper band, ahydraulic floor and rotating wall panels fur-ther assist the experimental character of thetheater space.
THE THEATER
69
The theater provides maximum flexibil-ity to arrange the seating. It can ac-commodate various arrangements ofthe stage such as a thrust, arena, oran innovative arrangement matchingthe creative drama. The movable floor,the main access to the workshop fromthe theater, provides convenience toinstall the stage.
70
SEATING ARRANGEMENTS
The rotating walls become both the door andthe wall. When the walls are closed, they con-nect to the other surfaces to complete the room.When they turn open, the walls disappear, andthey become separated pieces working as aboundary between two spaces. People can walkin or out between them.
THE ROTATING WALL

Conclusion
The design is not in making the elements. El-ements are realizations of the demands of thesite and its context. “ The design is the struggleto develop the elements into shapes compat-ible with each other, reaching for a wholeness,”and is realizations that “the order of structure,the order of construction, the order of time,and the order of spaces come into play.” --Louis I. Kahn. 77
