The antithesis of the previous example may be this Hillside House, where the wood beams are left in a natural appearance. This approach lends this space a warmth, but the treatment of the structure, the walls, and the windows has a simplicity that is still modern. It should be noted that the roof structure is not technically made up of trusses; they are rafters resting on beams at the bottom and meeting at a ridge beam above. The horizontal members in the center of the photo tie the two sides together for lateral support, where the rafters are doubled up, creating a nice rhythm.
