Text description provided by the architects. The client came to us with a derelict home on 20th street by Potrero Hill. The client´s had a basic need for an upgrade but also more space – to achieve this it soon became evident that expanding up through the roof was our only way. This would not only meet their needs, but could potentially take advantage of the view overlooking the San Francisco Bay. The existing 1575 sq. ft became 2225 sq ft – the private domain would remain on the 2nd floor – while the public functions would rise to an addition on the roof – a classic but clear programmatic division. We chose to fully comply with all the zoning regulations, and let that be the solution to our design strategies. We maneuvered through many City issues, but managed to solve the project requirements within the required setback of 15 feet, extending 32 feet in height, all within 175 dollars per sq ft.
