We redesigned and rebuilt this double-height porch in Westlake Hills to increase the view across a wooded valley and make it easier to access the back yard from the master bedroom. We replaced the existing heavy, rough wood members with thinner, smoother steel. We echoed the arcs of the existing bay windows with a bow-shaped deck, curving over to a spiral stair. Beautiful craftsmanship by Steelhouse. The spiral stair is really comfortable to use, as well as being a sculptural, sinuous form.
