By adding an upper story to this octagonal house, remodeler Sylvain Cote was able to capture a view of the lake. The house is capped with a cupola that has six operable windows for passive cooling during warm weather. The remodeler also installed trellises over south-facing windows and doors for summer shading, and chose tinted glass to reduce solar heat gain. Four of the roof facets hold photovoltaic panels. Exposed eaves have 4-foot overhangs to provide shading to minimize summer heat gain.
None of the interior walls are load bearing. Each level of the house has a different re-milled wood floor: hickory, chestnut and pine. The walls are natural earth plaster applied over drywall.
The dining table is made of surplus reclaimed wood flooring. The stone chimney rises 48-feet from the crawlspace, and is central to all three floors of the house.
