LABOR13

On the edge of the village of Vratislavice nad Nisou stands another house by Vesper Homes, realized according to the design of the architectural studio Labor 13 using the VF CLT construction system, based on a wooden frame structure and FERMACELL fiber cement boards. This house fulfills the vision of the young couple Eva and Jiří Magál, which, as with all buildings of this brand, combines modern architecture of wooden houses with layout solutions according to the needs of the house's inhabitants.

Czech representative in cross-country skiing Jiří Magál (a member of the bronze relay team in the 4x10 km at the Vancouver Olympics) is a professional athlete and needs a large amount of sports equipment for his training. However, the architects from the Prague studio Labor 13 took this into account when designing the house. The most prominent feature of the entire building is the external separation of the living room with the kitchen and dining area, where the roof also serves as a terrace for the attic room. The construction system allows for great variability in the placement of massive wooden panels, which were predominantly used visually in the attic. Vesper Homes wooden houses are also characterized by very short construction times, achieved through a high degree of prefabrication and the elimination of wet processes. Therefore, a dry FERMACELL system was used in the floor for underfloor heating.

Why did the Magáls choose a wooden house? "I began to consider a wooden house significantly for the first time after visiting a construction fair. Until then, I had only advocated for brick construction and was just thinking about the choice of materials. However, my opinion changed after I toured a model house from one of many companies. I realized how spacious these houses are compared to their brick counterparts, not only in terms of footprint," says Jiří Magál.

What was crucial for Vesper Frames regarding this house? Ing. Michal Šopík: "The Magáls chose us because they wanted a house according to their ideas. Therefore, we really followed the direction that we defined together with the architects and did not limit their visions by current technical possibilities. This created an interesting environment for fresh structural solutions, which also delights our designers. I would like to thank all parties involved for this, as we were able to move forward again."

The roof above the two-story part of the building is designed as a gable with a slope of 38°. The roof above the single-story part of the building is flat with thermal insulation made of EPS, covered with foil waterproofing weighted down with gravel. A standard roof window has been installed above the stairway area in the sloping roof. Additionally, the roof is equipped with solar panels for heating domestic water, flueing of the gas boiler, ventilation of the sewer, and snow guard.
