The building follows the site topography, considerate with the neighboring scale and height. The lot has a gentle slope to the South, which blends with the new sustainable envelope and aeration pattern. Massing and volume relations are well within the neighborhood characteristics. The addition is in fact a new take on a classical atrium composition in combination with modern design language and carefully planned sustainability. Most of the existing home’s foundation and exterior walls remain intact, along with the single existing bathroom. Nevertheless, with only 325 SF addition to the main home and partially elevated ceilings, the remodel makes a dramatic difference in form, function and feel. In a very honest approach to new and existing, portions of the old walls and roof are preserved, strengthened and resurfaced, clearly indicating the old house, while the new structure wraps around like a delicate elongated scarf. An artist studio and a bedroom are added to the garage accessory building to the North and both volumes are unified over a new atrium with three, fixed pergola elements to the West, North and East. They create a permanent ventilated shadow cushion over the essential outdoor areas, thus lowering the overall energy balance of the building. Aesthetically, they balance the solid portion of the atrium roof and create a light, aery feeling and a logical transition from sidewalk through public right-of-way to the building itself as a well articulated buffer zone, while promoting elevated sustainable standards with a zero-maintenance passive approach. Height is kept substantially below the limit - the building remains a one-story volume at about the extent of the existing structures, while the ridge lines of the new roof tie visually with the surrounding mountain profiles. Exposure and translucency are carefully controlled in regards to privacy - lower portions of street and neighbor exposed windows are handled with white glass and appropriate floral fencing.
