Merritt Crossing House en Oakland, California
Merritt Crossing es un nuevo desarrollo de apartamentos y servicios de alta densidad, asequibles y sin fines de lucro, para personas mayores de bajos ingresos, ubicado en el centro de Oakland.
Merritt Crossing is a new high-density, transit oriented development by a non-profit providing affordable apartments and services for low-income seniors in downtown Oakland. Located at the edge of Oakland’s Chinatown neighborhood near the Lake Merritt BART station, the project transforms an abandoned gas station site by an interstate highway into a new community asset. The non-institutional design combines colorful siding and panels with plant supporting wire mesh screens to compliment the neighborhood’s eclectic pan-Asian residential character. The building’s community-building amenities include on-site supportive services, a community room, and a landscaped courtyard and garden. The sustainable design achieved the highest level (Platinum) under the LEED for Homes rating system in addition to a high GreenPoint rating, Energy Star Rating and Bay Friendly landscaping certification. The building’s innovative sustainable systems include both photoelectric power and solar water heating, storm water retention, filtered ventilation, rainscreen facades and recyclable metal framing.

The building was arranged along the long edge (Sixth Street) of the corner site in order to reserve a twenty foot sideyard for a sunny landscaped courtyard and garden. This configuration also allows the courtyard to be directly linked to the ground floor community room, kitchen, laundry and entrance on Oak Street. The courtyard garden is designed as a series of outdoor spaces from community to more private activities. The high ceiling ground floor areas are surrounded by glass walls to enhance the visual connectivity of the community spaces and the public sidewalk. The footprint of the required on-site parking is reduced by the use of stacked parking lifts. The parking garage is wrapped with green screen panels that will create a living wall along the sidewalk and courtyard. In addition, planting beds are tucked under the street side of the building and double function as storm water retention tanks. By reducing the visual footprint of the ground floor level, the upper floors appear to float above which lightens their impact. The upper floors are organized into two parallel bands of apartments separated by a wide hallway combined with the fire stairs and elevators. The ends of the hallways are open with large windows to provide views and introduce daylight. Many of the apartments are provided with balconies that are recessed into the building mass. On the south (red) façade, the balconies are part of a recessed zone that mitigates the visual and noise impact of the adjacent freeway at the same time providing solar shading. The variety of openings and plant supporting mesh panels provides a freeway scale composition. On the north (green) faced the opening configuration provides a scale and variety compatible with the adjacent residential neighborhood. The building’s color scheme accentuates the separation between the two bars of apartments and between the outer building “skin” and the internal balconies and voids.
