The house is built as a shell so as to be the most stable possible to protect you and your property.

Interior walls are not bearing – that is why they can be formed of any material and type.

In order to obtain the best final result, the interior walls and windows have to be built in at the right time.


The choice of materials used depends on two fundamental points:

  1. Construction site and availability of the materials there.
  2. The owner of the house.

It is not good to combine everything – whether in terms of price or structural variations, but there are many possible combinations. An ever growing number of our clients are requiring the maximum use of natural materials. They know they will obtain healthier living for their children.


We use bentonite as waterproof insulation that in contact with water swells and seals the space. Another possibility is to use the crystal injection method that seals the concrete well, too.

Such insulation will persist as long as the concrete itself. The house can be insulated from inside with insulating coating, sprayed foam, or foil insulation – all applicable and repairable from the inside. More about waterproof insulation..

Concerning the thermal insulation and floor drainage, we use foam glass or liapor (i.e. expanded clay).


A combination of wood and concrete is used for the ceiling in accordance with sustainable architecture. Wood is coupled together with concrete for a higher load-bearing capacity. The layer of concrete is thick from 10 to 15 cm.

In order to make sure the house will last for more than 100 years, we use solid concrete progressively replaced by natural materials that also can persist much more than 50 years.

Construction is rapid thanks to the prefabricated wooden structure with precast concrete units used in contact with soil.

The single-layer facade wall is reinforced with thermal insulating bricks or fill-in insulation like wood-fibre insulation boards, straw, or wool.

Humidity in the house is regulated by natural materials such as wood-fibre insulation, wool, hemp insulation, clay plaster or boards and wood.

The open bearing construction of Molehouse gives the possibility to extend the house and its walls can be moved so as to give the house a new function.

The most modern construction methods


Have a look at our accomplishments.


We disposed of a north-western slope and wanted a Molehouse. We had no idea it could have facade on two sides. Thus, we benefit from privacy as well as sunlit home.



We want a house that makes us self-sufficient, a house, where we will be able to grow vegetables even in winter. We want a house, of which it will be easy to care.



After a long reflection, we chose Molehouse Pod Lesom (“Below the Forest”), because it meets our two critical requirements – self-sustainability and comfort.
