Project name: Hume

An unfinished, cramped portion of the attic being used as a home gym was transformed into an open, light-filled space with a spa-like bathroom – a much more pleasurable environment in which to work out and relax afterward. By constructing three new dormers in the roof with multiple sets of double-hung windows, the space is flooded with natural light. New support columns and microlam beams retain the structural integrity of the roof. The existing HVAC system was enclosed in a new, easily accessible closet. Ductwork was rerouted around the exterior walls and benches built over it to provide window seats. Light laminated flooring over a felt pad provides sound insulation to the rooms below. The bathroom includes a large open shower with multiple showerheads and a shower seat that hides the ductwork. Angled walls on either side of the window hide vent stacks. Warm and neutral colors in the paint and wall tile are contrasted by small dark glass accent tiles in the shower floor and white fixtures.
