The city of San Francisco is growing fast, and in every direction — especially up. Architects explain that the surge in housing has been met in two ways. First, historical homes and buildings are being renovated and retrofitted with modern facades to enhance and buttress the old. Second, brand new houses are also being built, often on plots and properties that were once considered too challenging to develop. That means the new challenge is finding a design that will make the most out of the smallest slice of pie: When land is limited, the new instinct is to go high (or diagonally, at least) by converting the hillside into a terraced landscape and raising the roof, literally, using beams and balustrades to extend sight lines. This article from Design Milk gives a fascinating overview of some of the uplifting new ways San Franciscans are claiming space.
