STACK EXCHANGE

MARKET ENTRANCE AT CORNER OF DELANCEY AND ESSEX

CONNECT

Stack Exchange celebrates the vitality and multidimensional community of the Lower East Side by referencing historical building tradition and urban context, integrating with transportation infrastructure, and advancing mass timber construction. By stacking housing similar to the lumber drying process, voids are created to allow for daylight, ventilation, and private and semiprivate amenity spaces. By connecting to the Williamsburg Bridge, Delancey Underground, and the subway, neighborhood residents and visitors from other boroughs are encouraged to engage with the site, Essex Street Market, and Andy Warhol Museum.

ENGAGE

Massing is comprised of stacked bars with voids between. Areas of double- and triple- height spaces contain the public program on ground floor. The expanded Essex Street Market is located on the western block where flexible market stalls are surrounded by permanent vendors. Half of the market is unconditioned and serves as a through block connection to the pedestrian-oriented Norfolk Street. The Andy Warhol Museum is on the eastern block and connects to the subway through a public gallery.

A larger scale ground floor condition along the car-dominant Delancey Street reinforces pedestrian movement on other edges of the site. Housing levels above are organized in two typical floor plans depending on unit type. The housing bars are stacked alternately and rotate 90 degrees at every level. Stack Exchange contains double the units required by the competition to address the lack of affordable housing in the neighborhood and to reflect New York City’s existing density. Units are larger than required to promote a higher quality of residential life for all family sizes and age groups.

COMMON ROOFTOPS AND URBAN AGRICULTURE

COMMON SPACE AND DAYCARE

THRIVE

Between the residential bars of Stack Exchange, the roofs of the floors below are used as enclosed and open-air residential amenities. On the micro unit levels, common spaces include shared kitchens and living rooms.

For the multi-room apartment levels, daycare facilities and co-working spaces are enclosed between the living spaces. Exterior unconditioned spaces such as sport courts, exercise areas, and p-patches are located in the voids along the edges of each level. Vertical circulation cores provide egress and are located at the intersection points of the stacked bars.

Each bar is single-loaded so that horizontal circulation is unconditioned and provides access between units and the residential bars.

ASSEMBLE

SECTION LOOKING SOUTH

The modular materials of the residential bars are assembled and flat packed at the nearby Brooklyn Navy Yard. Local construction processes creates jobs for the regional economy.

Flat pack boxes of prefabricated construction assemblies are transported to the site by truck across the Williamsburg Bridge. Each set of boxes comprises one section of the residential bars.

Stack Exchange takes advantage of the nearby construction industry and the material properties of Cross Laminated Timber. The primary structural system consists of box beams assembled from CLT panels.

Each residential bar is an occupied box beam that is assembled and stacked in a modular assembly. The construction materials are delivered as a flat pack from the Brooklyn Navy Yard and assembled on the adjacent empty lot. Floor cavities house services and provide structural stiffness. Windows and doors are cut into the side of the CLT at instances where shear is the lowest. Splicing occurs over long span areas and be supported by load bearing walls at the intersections of the residential bars. Shear panels between the units resist lateral and wind DEL loads. Residential circulation is located within the housing DELbox AN AN C CEY beams. EY S S
