House with Two Stairs
Renovation and addition to a Victorian house in the Leadville Colorado National Histoic District for a family of skiers. The addition preserves the existing historic house, wrapped in translucent skin on the interior, while adding a sawtooth expansion maximizing daylight and eastern views of the mountains.
Internally, both existing house and new addition are organized around a pair of volumetric stair cores —one new, one historic —containing storage, bathrooms, services, and vertical circulation, sheathed in plywood panels.
By retaining as much of the original structure as possible, Double Stair House limits its embodied carbon expenditure to only those elements of the house most in need of replacement, repairing and restoring what remains.
