Denver-based studio Tres Birds Inc<\/a> has completed a compact, gabled home using salvaged library<\/a> fittings and material from a bowling alley in Boulder, Colorado<\/a>, revealed exclusively<\/a> on Dezeen. <\/span><\/p>\n

Known as the Iris Residence, the 2,572-square-foot (240-square metre) single-family residence sits on a newly subdivided, interior portion of a 10,144-square-foot (942-square metre) lot.<\/p>\n

The low-energy home uses materials pulled from the client’s previous office location, which Tres Birds Inc<\/a>, formerly known as Tres Birds Workshop, designed in 2015 \u2013\u00a0an archival library for Shambhala Publications entirely out of maple plywood.<\/p>\n

When the business relocated to a smaller office in 2021, the shelves and furniture were put into storage for future use, finally finding one with Iris Residence.<\/p>\n

\"Energy
It sits on a narrow site in Boulder, Colorado, USA<\/figcaption><\/figure>\n

The residence is situated along a busy avenue, but the design refocuses spaces inward and shields the interiors from street noise.<\/p>\n

It is situated in a flood zone, which adds additional challenges to building on the site.<\/p>\n

“The most significant challenges were navigating local zoning constraints and meeting the minimum elevation requirements of the site’s designated flood zone,” the studio told Dezeen, noting the deep concrete base on which the house sits.<\/p>\n

\"House
The house is oriented towards the side and the backyard<\/figcaption><\/figure>\n

South-facing windows bring light into the linear house, while a south-facing courtyard provides a protected outside space, shaded by double-height columns that turn upwards to form the slats of a lanai.<\/p>\n

The grey-toned exterior requires little maintenance with vertical plank siding and a standing seam metal roof. On the interior, the salvaged materials were used to create new spaces.<\/p>\n

\"Library
It has a two-storey library, with elements reused from the client’s office<\/figcaption><\/figure>\n

Downstairs, a west-end garage leads to the library and guest room that pass into the primary bedroom on the east end of the house.<\/p>\n

The two-storey library leads up to the public areas of the home via a staircase with wood from a burned sugar pine forest.<\/p>\n
