The straw house is designed to meet the requirements of a low-energy house, i.e. the principle of sustainable development. Its basic building materials are wood, straw, and clay.
The family house is situated outside the contiguous built-up area of the village on Sluneční street, as part of a group of nine houses in gardens. The investor wanted to utilize knowledge of sustainable construction, but not at any cost. They were not required to use a gable roof.
Today, the house, along with other low-energy houses, is located on a large grassy area without tall vegetation. Nine houses, which are visually diverse, are built around a single access road. Whether we like it or not, we assess the straw house in relation to its surroundings. In this case, it is with the surrounding low-energy houses. The overall appearance of the development seems uneven and lacks harmony. It will take five to ten years for trees or shrubs on the plots of the houses to grow, at which point this unsatisfactory-looking group of houses will be enveloped in greenery. According to the project, there will be up to ten trees on each plot. The straw house is located at the end of this group, which means it will be completely concealed from the access road by both trees and vegetation on the green roof.
The external artistic solution of the straw house is pleasant and elegant. The materials of individual external building elements suggest the technical solution and concept of the entire house. However, this purely natural design (e.g., columns made from tree trunks, a facade made of clay and wooden strips, a green roof) is disrupted from the front by solar collectors placed on the railing of the balcony on the upper floor.
The load-bearing structure is designed from debarked logs. The peripheral straw wall of the heated part is either with a surface finish of a clay facade or with an external surface finish using wooden cladding. The peripheral wall of the unheated part is made up of boards, battens, panels, posts with a filling of sheep wool with a thickness of 100mm, and reed mats.
Composition of the straw peripheral wall: plaster with hydraulic binding multibat, mesh, straw bales with a thickness of 500mm, and posts, a masonry of unfired bricks with a thickness of 65mm, clay plaster Picas with a thickness of 10mm.
The composition of the roof's horizontal structure of the house is also divided into the structure above the heated part and the unheated part of the house. Above the heated part, the structure is designed from clay plaster, jute, roof beams, boards, clay suspension, reed mats, straw bales with a thickness of 350-380mm, paper separation cardboard, screed with MULTIBAT binding, rafters with a ventilated gap, a boarding of boards, geotextile, waterproofing foil, geotextile, soil substrate, and succulents.
