The design for this single-family development which includes 172 residential units over a parking structure which has two levels of below grade parking along with two levels of above grade parking and ground floor behavioral health clinic. The development provides a mix of affordable housing units for medical interns working in the health clinic and permanent supportive housing units with on site services. The design embraces the use of single use recycled shipping containers as a rigorous module in its five levels of housing on the upper floors which will be fully prefabricated modular units constructed off site.
The building massing is organized to efficiently provide parking levels and the ground floor clinic space on the lower levels with the concrete podium while providing an entry courtyard at the southwest corner of the site for the clinic and parking programs along with a midblock entry courtyard for the residential units on the upper levels. These courtyards along the sidewalk breakdown the scale of the building along the street to strengthen the public realm in how it connects to the community. The upper five floors of residential unit are organized along a perimeter spine organized along the south edge of the site with four fingers of residential units running north/south to shape a series on roof courtyards to promote social connections for the residents.
The courtyards open to the north to allow for the prevailing northwest breezes to flow into the site and to scale down the façade along the north into smaller massing blocks to respond to the surrounding residential neighborhood. The integration of landscape with architecture embraces biophilia in connecting people with nature to promote health and wellness. The use of modular construction innovates at every step of the delivery model from design, documentation, permitting to construction in promoting a lean delivery process in reducing the overall schedule. This development is currently under construction with the foundations being poured on site while the modular housing units are being fabricated off site.
The design embraces its diverse neighborhood context, a mixture of older apartment buildings, retail shops, health clinics and single-family homes. The design massing break apart to scale down along the north towards the apartments and single-family homes while creating a welcoming entrance along El Cajon boulevard with its entry courtyards and upper-level balconies above to connect the users to the community. The facade design is driven from the container module and then scaled down into smaller modules with the window proportions and vertical sunshades to create a multitude of texture and scale.
The integrated high performance design builds on the use of recycled single use shipping containers which are highly insulated for thermal and acoustical performance. The passive design features include natural ventilation with operable windows, daylighting and solar heat gain control with exterior vertical sunshades. The MEP system utilizes a high performance centralized VRF system and centralized electric heat pump boiler system for domestic hot water. The roof area is preserved for photovoltaic panels for energy generation and solar thermal panels for hot water generation. The exterior circulation system promotes health and wellness. There are multiple roof vegetated roof decks with a community vegetable garden to reduce heat gain and collect storm water. The site includes a biofiltration system to treat and store water collected on site while promoting biodiversity with its adaptive landscape palette. Overall building performance goals are being achieved to exceed 70% below title 24 and 86.6% below the AIA 2030 challenge benchmark. This project is designed as an all-electric development to promote carbon neutrality in its operations.
This project takes the humble shipping container that we’ve seen ubiquitously, but applies it in a sophisticated way, in a refined organization that feels dignified. Very well done in terms of massing, fenestration, tectonic expression, and material and colors. It delivers 172 affordable, 100% electric units which is an extraordinary achievement.
