Facing the new Union Center Plaza and poised to connect to the upcoming Union City Intermodal Station (featuring BART, Capital Corridor, ACE, and Dumbarton Rail), this new project expands the housing stock available as part of the Union City Master Plan. The Union Flats activates a beautifully landscaped promenade that runs to the north of Station Center, award-winning affordable housing that serves as the pioneer development in the area.

Modular Construction

The Union Flats used factory-built modular construction to realize significant cost and time savings. Guerdon Enterprises fabricated 388 "mods" in Boise, Idaho, while foundations were being poured in California. In May of 2016, these mods began arriving in Union City, where a giant crane "set" up to 12 a day.

The Union Flats brings 243 modern, practical rental homes suited for entrepreneurs and tech professionals, including 40 flexible live-work lofts, a new housing type for Union City.

The units encircle a large central courtyard filled with amenities for renters: a large swimming pool and freestanding green-roofed pavilions with spaces for yoga, gym, co-working, and a leasing office. The pool is shielded from view by the pavilions, yet there is a broad visual connection through portals from the street into the courtyard, revealing flashes of green and something of the inner life of the building.

Flex Lofts

 

At the corner of 11th Street and the promenade, the prominent entry is demarcated by a towering open-air stair, green walls, and a corner retail space that will initially house a community art gallery.

Live-work lofts line 11th Street and the landscaped promenade. These flexible loft spaces are set back from the property line an additional 10 feet, widening the sidewalks and creating space for ground-level patios. Along Berger Street to the north—above the live-work lofts—a diversity of unit types create housing opportunities for a wide range of residents.

Stoops

 

Keeping the surrounding streetscape active and vibrant, residential units along the newly created Berger Street feature raised stoops that connect directly to the sidewalk.

The building maintains an active edge on three sides. At the rear of the site, an embedded garage with 244 parking slots provides 1:1 parking and buffers the development from the sound of the adjacent rail tracks. The building massing is self shading, in response to its solar orientation. That is, at the southwest façade, balconies are recessed. At the northwest and southeast, bays are articulated to provide shade from the sun while opening up towards light and views of the nearby hills.
