We’re delighted to see the completion of the first stage of one of our timber framed eco-houses. The first stage is the completion of a watertight shell (walls, roof, doors and windows) by Meisterstueck, a German bespoke house manufacturer. The shell house is typically erected on site in 3-5 days.
Meisterstueck say: “All parts of the house are manufactured in the factory in Germany, transported to site and assembled by our permanently employed master carpenters. Each house segment can be up to 12m long, with all windows and external doors already factory installed. Our Energy Plus wall, which has been developed over decades to result in a 27.5cm thick wall with a U-value of 0.15 within the studwork, is closed in the factory, and only the final coat of external render is required on site. Computer-laser-controlled construction in the factory means no costly mistakes on site; and thermal bridges are designed out from the start. A brick wall would have to be more than 3 metres thick to achieve the same insulation properties as a 55cm layer of wood (cf report from Institute for Constructional Biology, Rosenheim). A study by this Institute found that a Meisterstueck-HAUS emitted 5.5 times less CO2 than a conventionally built house.”
Once the internal fit-out has been completed, the houses typically achieve airtightness test results of between 0.65 and 1.00 – virtually Passivhaus results.
