KDA transformed an existing single-story ranch house in Santa Monica to accommodate the needs of a growing extended family.

The design was impeded by several zoning restrictions which necessitated that this project be defined as a remodel. As a result, only 50% of the existing square footage could be added to the project. To respond to both the clients’ needs and these restrictions, KDA designed a new steel structure to be placed over and around the existing wood-framed house, creating an upper level with roof gardens.

Interior walls on the first floor were removed to create an open, loft-like space in the living/dining and kitchen. Corners of the existing first floor roof and walls have been sliced away to balance the geometries of the new second floor addition. The relatively small bedrooms are made larger by locating one single large opening that looks out to the view and in some cases opens onto the new roof garden. The exterior stucco is coated with bright orange elastomeric to create a monolithic appearance. The garage is planted with an intensive green roof to be used as a herb and vegetable garden.

Ten years after its completion, changes in local regulations permitted the construction of an additional guest house and screening room. The geometry of the original building is reflected in an additional bar added to the rear of the property, which engages with the surrounding landscape. A lap pool parallels the addition.
