This second-floor renovation adds height to the shallow-ceilinged 1920s home in the form of a dormer. The increased height brings about a vast increase in natural light via large triple-pane windows. The wood flooring is VT red-maple, and a hand-crafted banister is made from site-milled butternut and box elder. Twelve-inch walls are insulated with dense-pack cellulose, and a new HRV (Heat Recovery Ventilation) system brings in fresh air and recovers heat from outgoing air. Renovation projects like this one offer the opportunity to greatly increase the energy-efficiency of older homes while providing modern design updates.
