There were numerous structural and woodworking challenges in building this Sebastopol house.  The owners were intimately involved in the day to day evolution of the design and set up a shop on the property, where we produced all of the specialty doors and milled all of the custom trim.  The central, three story tower, is an ellipse built within a circle.  The staircase separates the two, requiring each stair tread to be a different shape.  We broke up the elliptical, living room ceiling into pie shapes, each one stepping down in elevation and faced in Port Orford cedar boards with mahogany splines.  The shower surfaces are smooth-trowelled, cement-based and waxed plaster.  The kitchen cabinets are madrone and the countertops custom concrete.  We formed the rough shape of the fireplace for poured concrete and then plastered the exterior.
