Can you imagine how much your electric bill would be each month if you had to house four generations of family members under one roof? Fortunately, those potentially astronomical energy costs are no problem in TICA Architecture’s 2 in 1: Intergenerational House, an energy-efficient, four-generation house that follows bioclimatic principles and draws energy from geothermal sources. Located in Vaux-sur-Mer, France, the metal and timber-clad building is sited on a narrow lot near the sea.
The 2 in 1 house derives its name from its spatial layout, which splits the building into two separated dwellings that are connected by a series of shared spaces. The communal areas, which help preserve privacy on both sides of the house, include a cave-like space in the basement, an atelier on the ground floor, and an upper terrace on the first floor. The bedroom types comprise a variety of different styles, from the playful boat bunk beds to an elegant bedroom suite with a terrace.
Although the exterior is clad in metal, cross-laminated timber lines the interior to create a pleasant and cozy atmosphere. Large windows are strategically placed to take advantage of natural ventilation and cross breezes. South-facing rooms and windows reduce the need for artificial lighting and heating. The energy-efficient house is powered by geothermal energy sourced from underground waterways.
