Site Planning & Urban Design
This project was designed as a STUDENT HOUSING project to be located on Livernois across from its home campus, the UNIVERSITY OF DETROIT MERCY. It’s design would be constructed as MODULAR housing while also meet PASSIVHAUS criteria. The site’s west side also shares a border with Detroit’s FITZGERALD NEIGHBORHOOD. This neighborhood is already undergoing its own revitalisation project to stabilize and strengthen the neighborhood by transforming vacant land and houses into community assets.

After an initial site analysis, the site was assessed and refigured itself. At the northern end of the site, 60 DEGREE PARKING was planned for to accomodate 25 SPACES with generous GREEN SPACE between aisles. While at the southern end, a DROP OFFfor the propsed DAYCARE space would span from Livernois to the parallel alley. Livernois itself would also be reconfigured to accomodate BIKE LANES on both sides and PARALLEL PARKING on the commercial side of the street with only minor adjustments to the existing median.

Schematic Design MODULES were designed to measure a total of 8’ wide, 25’ long, and 10’ tall so that two would be able to fit on a semi
truck with ample room for their exterior panels to be attached as well and be shipped without the need for special permits. Once on site, the modules would come together to create FOUR UNIT TYPES. The main unit type would comprise four modules with one additional stair module that would CROSS OVER A CENTRAL CORRIDOR. A second unit type would also use four modules, but would create an L-SHAPE that sits on top of the first unit type. The third unit type would be made of two conjoined modules forming a STUDIO APARTMENT. The fourth and final unit type would bring together three modules to form ADA UNITS.

Structure The structure of the project would be entirely made of steel and concrete. The FIRST FLOOR would be ERECTED ON SITE while all modules would be constructed in factory and brought together on site upon completion. The first floor would have concrete footings and a 4” SLAB poured on site. 12x12 STEEL COLUMNS would be placed every 24 feet with intermitent TRANSFER BEAMS to catch the loads of the modules above. All CONNECTIONS would be WELDED to their connecting columns. All MODULESof the above units would be constructed using light gauge steel framing. 4x4 TUBULAR STEEL would be used for the columns and beams with welded connections. 2” METAL DECKING with concrete filled in would serve as flooring for all units and the corridors spanning the second and fourth floors.

Interior Design, Lighting, & Acoustics Coming to the interior, adequate living, cooking, dining and sleeping areas would be made inhabitable by students with SIMPLE FURNITURE within AMPLE SPACE. The large 25 foot wide CORRIDORS, on the second and fourth floors, themselves would also be accompanied by furniture to create PUBLIC SPACE between units where students could gather to study or just socialize. Even with walls towering over the corridors there would still be plenty of NATURAL LIGHT to make its way within the space with complementary cove lighting and various fixtures to light pathways and SOCIAL SPACES for gathering.

UNIT INTERIORS would provide GOOD LIGHTING conditions naturally along with artificial lighting provided by the same fixtures as the public spaces. The furniture and MATERIAL PALETTE of the units would be similar. RUBBER FLOORING with a DARKWOOD APPEARANCE would be provided by Artigo. The kitchen cabinets would resemble a similar shade, with STAINLESS STEEL kitchen appliances, and a QUARTZ COUNTERTOP by Allspice. Living spaces would be occupied by various FURNITURE from MONACO and LEKOLAR. Finally, interior WALL CONSTRUCTION would have an STC RATING of 67 for adequate SOUNDPROOFING between units.

PASSIVHAUS requirements will ensure that the envelope of the building will maintain a COMFORTABLE TEMPERATURE in both winter and summer months. The construction will be AIR TIGHT, forming a balloon for the buildings interior. The VENTACITY VS1000 will provide air flow in and out of the building maintaining VENTILATION. The unit placed on the roof will run exposed ducts down the spaces between staircases and along the corridors to supply and exhaust air for each unit. If extra HEATING or COOLING is desired, a MITSUBISHI Mr. Slim unit will be in every unit.

HVAC Plan For the entire building to run on solar power would require, 22 12sf panels per unit. Without enough space, the max amount of panels would be placed on the roof to renew as much solar energy as possible.
Water Harvesting System Harvested Water= Roof Areax Rainfall (in) x 0.64 14,400 x 31.73 x 0.64= 292,423.68gallons/year With each resident using 1,000 gallons of water on a monthly average, a water harvesting system that could catch most of the rainfall would save almost 25,000 gallons of water a month on average.

Building Skin and Construction
For the final piece of the project, the EXTERIOR ENVELOPE would have two parts. The FIRST FLOOR would have wood framing for all insulation pieces to attach to with a BRICK FINISH as the exterior skin. The MODULES would have PANELS to attach directly to the steel structure constructed of WOOD FRAMING for better thermal bridging properties along with insulation and WEAVING ALUMINUM PANELS that would make up a majority of the facade.

Module Window
Module to Module
The panels that attach to the modules, from interior to exterior, would consist of 1/2” Retrofit board, 2x8 wood framing, 7&1/4” of spray foam insulation, 1/2” Retrofit board, 4&1/2” foam sheathing with a foil face, a 3/4” air space and finally the angled and perforated aluminum panels would attach to rails once all modules are put together on site. For each unit, the window construction would use wood framing and triple pane low-E glass with argon filled spaces. Finally the roof, would have a PVC membrane that would attach directly to the foam sheathing insulation. In total, these walls provide an R-VALUE of 63.

Aluminum Panels Aerial Perspective Seperate from the modules, the first floor would use the same construction method, but its facade would be made up of brick instead of aluminum panels. The foundation would have large concrete footings set 42� into the ground with a gravel bed and a four inch poured concrete floor.
