You want to build a little and ecological smart home on a smallest plot with minimal energy consumption?

Build in partnership with nature.

Our kleinsthäuser (minimal houses) provide living comfort and a great indoor climate.
The houses have very low CO2 emissions: Heating and hot water require only electrical energy.
An own photovoltaic installation supplies free solar power which covers a major part of your power demand, thus keeping your electricity costs low. A battery storage device accumulates the generated energy when it is not used..
There are no expensive provider connections, no monthly fees and no waste of space.

Our smartcubes, which are made in Germany, are provided with a smart home solution reducing electrosmog and enabling you to monitor your energy consumption and battery storage and to experience tailor-made comfort, e.g. by controlling the motorized rolling shutters. The smart home also improves safety for the house and the people living in it, and it generates an optimal energy and cost efficiency.

kleinsthäuser are suited for anyone planning to build a house, such as couples, singles, hedonists, entrepreneurs, families, seniors, holiday home owners and companies.
They can be reconstructed, e.g. into an office building. They can also be enlarged or extended to other existing kleinsthäuser.
Even for people in need of care and their relatives, our kleinsthaus can be a solution. The care recipient can stay on the own property which thus becomes multigenerational. The family can stay together while everyone still has their own space.

Nature conservation and sustainability

I, founder and owner of kleinsthäuser, have been working in general building design for more than 20 years. In the meantime, the average size of a new-built single-family house has exceeded 160 m²; the impervious surfaces in a regular-sized property often make up around 45 %.

Additionally, building new homes is getting more and more expensive. Between 2000 and today, the increase was around 40 %. Rents are increasing as well (around 30-50 % of the net income is spent for living), just as the housing demand.

It is imperative to prevent further expansive sealing of soil and to present alternatives. In Germany, around 65 hectares (81.250 m²) of soil are sealed every day! As a consequence, natural processes are disrupted: Rainwater cannot infiltrate to produce groundwater; moisture cannot rise to cool the air; droughts, heavy storms and floods may be caused

Concentrations of certain substances and groundwater pollution may increase because less nutrients and pollutants are filtered when rainwater can only infiltrate in isolated patches.

Around 50 % of the surfaces for settlement and traffic in Germany are sealed for pavements, roads, sports fields, railways, airports, deposits, dumps, cemeteries, housing, commerce, industry and disposal, i.e. around 10 % of the whole surface in Germany is artificially sealed and thus lost as habitat and soil for humans, animals and plants.

Even subterraneously further impervious surfaces are constructed in order to create an infrastructure for the supply and burial of people near cities. This implies that mobility needs to be increased; new route maps, shopping malls and service providers are required causing more surfaces to be sealed.

People should get back to living a sustainable and healthy life, e.g. through sports and a specific diet; but it can also mean to thoughtfully choose a new car or the kind of house you want to build. It is the orientation towards the things that are important in life and which give you the feeling of living a conscious and minimalistic instead of an abundant life, which is nevertheless happy and sustainable.
