Stommel Haus Heather - nominated for the Green Footprint Award

With the very first house built in the UK, Stommel Haus got nominated for the Green Footprint Award of North Leicestershire County Council in 2012 and scored “Highly Commendable” in the category “Sustainable Urban Design”. The owners of the house “Heather” were thrilled with the quality of the build, the adherence to schedule and to budget and most of all with the amazing energy efficiency and special atmosphere in their healthy home.

The third home built by Stommel in the UK, called „Silver Birch“, was shortlisted for the very renowned Build It Award 2014 for the category “Best Timber Frame House”. In the shortest possible time frame, Stommel Haus helped to fulfil the dream of Connie and Drew Minton for a healthy, energy efficient family home in London. The owners lovingly call their house the “Trojan House” because of its Mock Tudor design on the outside and its high quality interiors and state-of-the-art building technology on the inside.

The beautiful "Ashdown House" was shortlisted for a Build It Award in the category "Best Timber Frame Home".

The house is a fantastic example of a bespoke, contemporary and very energy efficient home.

It was built in a conservation area in East Yorkshire.

The Stommel Haus wall was shortlisted for a Build It Award in 2015 for "Best Sustainable Technology.

The wall is unique: It uses only non-toxic natural and sustainable building materials. It has excellent energy efficiency and provides the means to build very healthy and also very contemporary buildings. The interior atmosphere in a house built with Stommel Haus “Elementar”-Wall is particularly good which the owners of the houses can confirm.

The thickness of the wall is 34.5 cm. It is made of seasoned Scandinavian polar spruce heartwood from FSC certified forests with the heart turned to the visible side.
The centre is a 16 cm timber frame made of Polar spruce, insulated with recycled glass or recycled newspaper.
The timber frame is clad on the outside with 50 mm thick Polar spruce heartwood. The u-value of the wall is 0.17 W/m²K in the wall.
There are different models of the wall, the wall can be provided with a sustainable thermal render bearing panel ready for rendering. The inside timber can be replaced by a double layer of gypsum fibre panel ready for skimming and painting, allowing for contemporary architecture.
The multi-layered construction avoids tensions within the wall caused by different climate conditions and temperatures inside and outside. The construction provides a very good heat insulation and sound protection and allows flexibility in design and installations. The solid timber frame in the centre allows for contemporary constructions with lots of glass.
