The Marina Residence is a new fourth floor addition and a complete interior renovation of an existing multi-unit building. The project expands the third floor unit into a two-story penthouse unit, centered around an interior stair that serves as the domestic heart of the building and the center of family activity.

The fourth floor addition fits into the context of the residential neighborhood while standing apart from the Victorian styling and bay windows that characterize mid-century San Francisco architecture. Defined by a thin shell that lands lightly on the existing building, a series of portals take advantage of the project site to open up towards a series of signature views of the city by the bay.

To address the city’s dire housing shortage, CO- was commissioned to produce a preliminary study of potential Accessory Dwelling Unit (ADU) models for San Francisco’s Sunset neighborhood. Many mid-block parcels throughout the city include underutilized rear yards that can be redeveloped into small homes to help address the demand for more housing in the City.

CO- created three distinct proposals for a standalone 550sf ADU for the client’s consideration. Each ADU includes a kitchen, bathroom, bedroom, and a small living space. Drawing inspiration from the surrounding context of the Sunset, the ADUs are developed to respond to the massing and materials of the neighboring single-family homes.

CO-, in collaboration with the San Francisco ADU Center, will produce a collection of designed and permitted ADU models that can be adapted to new sites across the City.

Sujung Hillside proposes a model for community housing that adapts and innovates Busan’s hillside architecture. By combining 325 residential units with community and commercial amenities, parking, and recreational open space, the project establishes a coherent and connected urban moment while also creating space for personal interaction. Three community and commercial linear buildings align with the street grid and connect with the existing city fabric. These amenity buildings contain a variety of public and private green spaces, retail storefronts, children’s daycare, senior community center and access to subterranean parking. Four residential bars exist above, two of which are reoriented to face due south and connect directly to the public amenities below. The residential floors are tiered and set back so that every residential unit has unhindered south facing exposures and sweeping ocean views.

The site is nestled in between two very different contexts, beautiful green forests exist to the north and residential and commercial buildings to the south. The facade of each building is designed specifically to respond to each condition. The northern facade is designed with a highly reflective surface, a hiker at the top of Gubong-san looking towards the city would see a continuation of lush green forests reflected back. The southern facade is designed in respect to the surrounding urban fabric. The buildings are terraced and the facade is faceted to blend in with the terraced housing to the south. Vibrantly colored panels are proposed across the residential facade as a homage to the vividly colored residences that are dotted across Busan’s cityscape.

CO- has commenced a renovation of a 2000sf apartment in downtown San Francisco. The 5-bedroom unit will be renovated with a new kitchen, bathrooms, finishes and appliances.
