The proposed family house is located on the edge of the built-up area, but still close to the center of the village. The specific location offers undisturbed natural environments with views mainly in the northwest direction.

We partially adjust the slight slope by modeling the terrain, thanks to which we can orient the object along the longitudinal axis in the north-south direction. At the same time, we preserve the views and structural simplicity and single-story building. The archetypal design of the house is based on the requirements of the spatial plan, as well as efforts to effectively deal with the economic side of the project.
The northern gable wall is recessed within the attic space and forms a roof terrace. Since the request of the authorities was for a gable roof over the entire main building, we will complete the shaping of the roof over this terrace as well. So it is not a formalistic element. A roof terrace is usually unnecessary for family houses with a large enough plot, but in this case it allows a direct view from the slope to the valley, which was one of the main requests of the client.
After careful consideration, we propose the construction of the family house as a wooden structure using sustainable construction technology using hemp concrete, which is probably the only construction material with a minus CO2 footprint today.
Technologies:
From a technical point of view, the family house uses several technologies and materials, which contribute to the low requirements for the construction and operation of the building and thus its sustainability.
– perimeter structures made of a combination of wood and hemp concrete
– low-temperature floor heating using a heat pump
– drainage of rainwater into infiltration pits on the property
– forced air exchange using a recovery unit
– use of gray water for flushing.
Advantages of hemp concrete:
– the material absorbs CO2 during growth, a hectare of sown hemp rids the planet of more CO2 than a hectare of forest
– “carbon negative” – negative CO2 footprint, or removal of CO2 from the air during calcification / hardening of the structure
– phase shift as in massive constructions
– diffusion open construction – natural humidity regulation of the internal environment
– it accumulates heat well – no additional insulation is needed even with a construction thickness of 45 cm
– excellent soundproofing properties
– repels insects except bees and deters rodents and pests
– after demolition, hemp concrete can be crushed and used as fertilizer.
