Castro Moon Residence

The Castro-Moon residence is a third story addition to an existing house for a young and growing family that needs to add space to their small and inefficient house in the Inner Sunset.

The upgrade of the house includes an additional third story that follows the footprint of the existing building as well as a new façade, an enlarged sunroom in the backyard and several minor changes to the existing interior layout.

The new design separates the public and the private areas of the house, providing a larger and more open public/entertainment area that now directly opens up to the backyard and a private new upper floor with 3 bedrooms and 3 baths that takes full advantage of the existing views to both sides of the building and that includes a “sky-court” which provides light and ventilation to the otherwise dark central area of the floor-plate.

In order to minimize energy consumption as well as the carbon footprint of the building an energy efficient radiant heating system is being used throughout the building while natural ventilation, solar access as well as a solar water heating system is being maximized. Sustainable materials will be used throughout.
