The idea is simple, yet effective—a revolving house turns on its own axis, following the sun, so that it can use the sun’s energy around 200 % more effectively than fixed buildings.
The revolving house actively collects energy. It works so well that we’ve built a house that produces more energy than it uses. An active house, in fact.

“DrehHaus”—the intelligent active house.

How the idea continued to develop

With the construction of the 2nd “DrehHaus” generation, we’ve further improved the insulating qualities of the house and integrated the most modern technologies into our building. Total energy efficiency is possible in combination with the rotatability.


The 2nd generation has a new supporting structure concept. It architecture to become freer and more contemporary. We’ve maintained the basic principles of the design (rotatability and the smallest possible perimeter area) because they work.
The roof is designed to be flat to combine the photovoltaics technology perfectly with our revolving house.

Construction material

This building is also made from timber. It’s the best raw material if you want to build ecologically, with a positive effect on the climate. This creates a healthy living environment, because the vapour-permeable building cladding allows the house to breathe. As a construction material, timber also regulates moisture.

The most modern technology

Rotatability: Optimised motor control in hard and software according to the sun’s movements by time of year. Alternatively can be switched to manual control or using the connected exercise bike.

An earth heating pump is used for heating. An air conditioning unit with heat recovery keeps air quality high and minimises heat losses through ventilation. Heat losses through the perimeter surface are reduced to a minimum using passive house windows, doors and wall superstructures.

The photovoltaics elements produce electricity and the solar thermals heat the water.

Save water, electricity & gas—steady drops make savings.”

The residents

People who live in or use the building also benefit from its rotatability. In the revolving house, they can enjoy evenly lit rooms all day—boosting their sense of well-being.

We’re just like a sundial, only the sunny hours count.”
