Photography by Jim Tetro This house, built in the 1960s, sits southfacing on a terrific wooded lot in Bethesda, Maryland. The owners desire a whole-house renovation which would improve the general building fabric and systems, and extend the sense of living out of doors in all seasons. The original sixties-modern character is preserved and the renovation extends the design forward into a contemporary, modern approach. Connections to and through the site are enhanced through the creation of new larger window and door openings. Screened porches and decks perch above the sloped and wooded site. The new kitchen and bathrooms allow for opportunities to feel out-of -doors while preparing, cooking, dining, and bathing. Smart passive strategies guide the environmental choices for this project, including envelope improvements, updated mechanical systems, and on-site stormwater management.

Rather than starting with an outcome in mind, this 1,400 square foot residence began from a polemic place - exploring shared conviction regarding the concentrated power of living with a smaller footprint. From the gabled silhouette to passive ventilation, the home captures the nostalgia for the past with the sustainable practices of the future. While the exterior materials contrast a calm, minimal palette with the sleek lines of the gabled silhouette, the interior spaces embody a playful, artistic spirit. From the hand painted De Gournay wallpaper in the master bath to the rugged texture of the over-grouted limestone and Portuguese cobblestones, the home is an experience that encapsulates the unexpected and the timeless.

The Twin Peaks Passive House + ADU was designed and built to remain resilient in the face of natural disasters. Fortunately, the same great building strategies and design that provide resilience also provide a home that is incredibly comfortable and healthy while also visually stunning. This home’s journey began with a desire to design and build a house that meets the rigorous standards of Passive House. Before beginning the design/ construction process, the homeowners had already spent countless hours researching ways to minimize their global climate change footprint. As with any Passive House, a large portion of this research was focused on building envelope design and construction. The wall assembly is combination of six inch Structurally Insulated Panels (SIPs) and 2x6 stick frame construction filled with blown in insulation. The roof assembly is a combination of twelve inch SIPs and 2x12 stick frame construction filled with batt insulation. The pairing of SIPs and traditional stick framing allowed for easy air sealing details and a continuous thermal break between the panels and the wall framing. Beyond the building envelope, a number of other high performance strategies were used in constructing this home and ADU such as: battery storage of solar energy, ground source heat pump technology, Heat Recovery Ventilation, LED lighting, and heat pump water heating technology. In addition to the time and energy spent on reaching Passivhaus Standards, thoughtful design and carefully chosen interior finishes coalesce at the Twin Peaks Passive House + ADU into stunning interiors with modern farmhouse appeal. The result is a graceful combination of innovation, durability, and aesthetics that will last for a century to come. Despite the requirements of adhering to some of the most rigorous environmental standards in construction today, the homeowners chose to certify both their main home and their ADU to Passive House Standards. From a meticulously designed building envelope that tested at 0.62 ACH50, to the extensive solar array/ battery bank combination that allows designated circuits to function, uninterrupted for at least 48 hours, the Twin Peaks Passive House has a long list of high performance features that contributed to the completion of this arduous certification process. The ADU was also designed and built with these high standards in mind. Both homes have the same wall and roof assembly ,an HRV, and a Passive House Certified window and doors package. While the main home includes a ground source heat pump that warms both the radiant floors and domestic hot water tank, the more compact ADU is heated with a mini-split ductless heat pump. The end result is a home and ADU built to last, both of which are a testament to owners’ commitment to lessen their impact on the environment.
