Exterior, House Building Type, Flat RoofLine, and Concrete Siding Material To deal with a Malibu site’s sharp incline, architect Bruce Bolander set the steel, concrete, and glass house on caissons. A deep wraparound porch nearly doubles the home’s living space and offers the ideal perch for outdoor dining and taking in spectacular views of the surrounding canyon. The garage serves as resident Dave Keffer’s home office. Photo by J Bennett Fitts.  Photo 4 of 9 in Malibu Canyon House with a View
