Boise House of Passive Principles by Haas Architecture

Designed by Haas Architecture, Boise House of Passive Principles has a modernist style with a minimalist palette consisting of timber, steel and white walls, creating a sleek and clean appearance. Perched above Boise, Idaho, the home exemplifies passive design principles.

The design of the dwelling was shaped by the owners’ commitment to healthy living and environmental stewardship. Reflecting a need for connection with the natural surroundings, the layout is divided into two wings that follow the site’s natural topography. This division not only enhances privacy by separating private spaces from communal areas like the kitchen, dining and living rooms but also fosters a sense of flow throughout the home. Entry into the residence is through a light-filled foyer at the rear, which serves as a glazed bridge spanning and uniting the two wings.

Reflecting a need for connection with the natural surroundings, the layout is divided into two wings that follow the site’s natural topography.

The home’s orientation and layout are designed to maximise solar gain, with strategically placed glazing harnessing the afternoon sun while preventing overheating in summer. Curved rooflines not only enhance natural light but also integrate indoor and outdoor spaces. Effective insulation and thermal bridging also help to maintain interior comfort by minimising moisture and cold air.

The bedroom wing nestles into the hillside, featuring a second-storey studio that doubles as a lookout – an important feature in this fire-prone location. To safeguard against smoke infiltration during wildfires, the abode is equipped with a continuous, airtight building envelope that seals out polluted air. A heat and energy recovery ventilator ensures constant fresh air is circulated inside. Additionally, the home achieves near-net-zero energy consumption, thanks to a solar array that includes hot water heating.

Natural materials play a key role in the dwelling’s passive design principles, with timber cabinetry and floors and low-VOC painted walls creating a clean, simple palette. The integration of antique pieces and existing furniture from the owners’ previous house imbues a comforting familiarity, creating a compelling contrast against the blonde timbers in the open-plan kitchen and dining area. Interior design by Pappas Miron Design showcases considered furniture selections and rich pops of colour, such as the green bedroom walls, vibrant rugs and art pieces scattered throughout the home.

The design brief emphasised creating a residence that fosters play, relaxation and a strong connection with nature. Details like the staircase designed to transform into a child-friendly bench, as well as a cosy daybed next to the fireplace, reflect this intention. Various windows and openings invite the outside world in, and with its thoughtful details and unique location, the home offers a family-orientated lifestyle close to the city, blending with its natural surroundings.
