This Boulder, Colorado remodel by fuentesdesign demonstrates the possibility of renewal in American suburbs, and Passive House design principles. Once an inefficient single story 1,000 square-foot ranch house with a forced air furnace, has been transformed into a two-story, solar powered 2500 square-foot three bedroom home ready for the next generation. The new design for the home is modern with a sustainable theme, incorporating a palette of natural materials including; reclaimed wood finishes, FSC-certified pine Zola windows and doors, and natural earth and lime plasters that soften the interior and crisp contemporary exterior with a flavor of the west. A Ninety-percent efficient energy recovery fresh air ventilation system provides constant filtered fresh air to every room. The existing interior brick was removed and replaced with insulation. The remaining heating and cooling loads are easily met with the highest degree of comfort via a mini-split heat pump, the peak heat load has been cut by a factor of 4, despite the house doubling in size. During the coldest part of the Colorado winter, a wood stove for ambiance and low carbon back up heat creates a special place in both the living and kitchen area, and upstairs loft. This ultra energy efficient home relies on extremely high levels of insulation, air-tight detailing and construction, and the implementation of high performance, custom made European windows and doors by Zola Windows. Zola’s ThermoPlus Clad line, which boasts R-11 triple glazing and is thermally broken with a layer of patented German Purenit®, was selected for the project. These windows also provide a seamless indoor/outdoor connection, with 9′ wide folding doors from the dining area and a matching 9′ wide custom countertop folding window that opens the kitchen up to a grassy court where mature trees provide shade and extend the living space during the summer months. With air-tight construction, this home meets the Passive House Retrofit (EnerPHit) air-tightness standard of

Our client, with whom we had worked on a number of projects over the years, enlisted our help in transforming her family’s beloved but deteriorating rustic summer retreat, built by her grandparents in the mid-1920’s, into a house that would be livable year-‘round. It had served the family well but needed to be renewed for the decades to come without losing the flavor and patina they were attached to. The house was designed by Ruth Adams, a rare female architect of the day, who also designed in a similar vein a nearby summer colony of Vassar faculty and alumnae. To make Treetop habitable throughout the year, the whole house had to be gutted and insulated. The raw homosote interior wall finishes were replaced with plaster, but all the wood trim was retained and reused, as were all old doors and hardware. The old single-glazed casement windows were restored, and removable storm panels fitted into the existing in-swinging screen frames. New windows were made to match the old ones where new windows were added. This approach was inherently sustainable, making the house energy-efficient while preserving most of the original fabric. Changes to the original design were as seamless as possible, compatible with and enhancing the old character. Some plan modifications were made, and some windows moved around. The existing cave-like recessed entry porch was enclosed as a new book-lined entry hall and a new entry porch added, using posts made from an oak tree on the site. The kitchen and bathrooms are entirely new but in the spirit of the place. All the bookshelves are new. A thoroughly ramshackle garage couldn’t be saved, and we replaced it with a new one built in a compatible style, with a studio above for our client, who is a writer.
