San Diego, like many cities, has run out of open space and faces the challenge of how to thoughtfully increase residential densities. Instead of reinventing the wheel, this self-developed 17 unit in-fill project located in downtown’s East Village neighborhood, borrows liberally from the East Coast rowhome typology adapting it to So. Cal’s temperate year around climate.
The 17 rowhomes were created by assembling 217 tilt-up concrete panels on individual micro-parcels with only three inches of airspace separating each home. Each rowhouse, at only 16’-4” wide plus the airspace, allows for three single family homes to fit on a City standard 50’-0” wide parcel, thus tripling the density to 42 units/acre. The airspace separation allows for a single family “fee-simple” classification, thus no H.O.A.’s is needed.
New methods for pre-casting, transporting, and setting the over-sized panels were developed to meet the design and density requirements of this project. This highly innovative solution proved to be a very fast construction method and cost effective in addition to significantly reducing sound transmission between homes, potential damage from water intrusion, termites, and mold.
The rowhomes were designed to be energy misers, achieving and far surpassing the stringent “Energy Star” designation, rating 42% more efficient than State energy standards. Double height spaces, open floor plans and strategically located Low-E glazed operable windows were designed to take full advantage of natural day-lighting and consistent cooling bay breezes ultimately eliminating the need for an air conditioning system. The high mass walls significantly balanced internal temperatures providing thermal comfort while also mitigating noise transmission from the busy street as well as between units.
Overall, this forward-looking project models a viable residential design strategy which begins to answer issues such as increasing urban density, cultivation of neighborhoods, natural resource conservation, and environmental sustainability without sacrificing a modern design aesthetic.
