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.

The marble tile shower has a barn-style sliding shower door. Even small spaces need a well designed lighting plan; the bath’s skylight provides natural lighting, while the floating light shelf with small puck lights and a hidden strip light at the rear provide additional lighting.

Burlwood cabinets compliment 2" x 12" neutral toned glass tiles.

It's amazing how much larger a bathroom can feel when it's brand new! This master bathroom had a functional layout, but was in need of an update! The homeowners wanted something fresh, light, and timeless. The flooring and shower walls are limestone tile, the vanity is stained maple cabinetry with soft close doors and drawers, which pair perfectly with the quartzite countertop, and the shell mosaic backsplash. The plumbing fixtures are brushed nickel, as is the cabinet hardware, and the mirror picks up both the warmth of the tile, and the silver of the fixtures. The same shell mosaic pops in the recessed niche in the shower.
