This modern addition of steel, glass and concrete utilized exposed detailing and graceful geometry to create a new and exciting entry experience for an existing, wood-framed house in Larkspur. The curved concrete entry bridge cantilevers over its two round concrete columns, stepping down as it approaches the house. The step and guardrail detailing make practical requirements a design opportunity, and result in a refined convergence of architectural and structural requirements. The elegant steel entry structure consists of light structural steel elements with glass façade. A new hardwood deck balances out the entry sequence.
