Renovation of an 1896 house in the Haight by Casper and Lexie Mork-Ulnes: a nearly $200,000 renovation over the course of five years. Salvaged lumber was glued together to form the butcher-block treads of the parlor staircase; chips and nail holes were left exposed. The railing is made of shower-door glass and industrial hardware.
