We plan and realise for you


Our prefabricated buildings are designed to be energy efficient and sustainable. They are assembled on a production line directly at the building site, and the completed modules are lined up and connected storey by storey.


Efficient implementation results in exceptionally short build times. LiWood’s materials are carefully selected according to criteria of sustainability and high quality. Primarily wood, combined with gypsum fibre, glass and reinforced concrete.

Only innovative timber construction can support energy-efficient living

Due to the relatively low thermal conductivity of wood, passive or zero-energy housing can be achieved. Heating or cooling energy is obtained in an environmentally friendly and economical manner through the installation of air-water-heat pumps which feed into the heating and cooling systems via the building’s own energy centre. In addition, a suitably-sized photovoltaic system with minimal maintenance requirements and a long service life, generates a large proportion of the electricity required for the air-water-heat pumps.

In contrast to conventional heating systems which have flow temperatures of 70 to 90 °C, surface heating systems require significantly lower temperatures (approximately 35 °C flow temperature). Moreover, the excellent U-values of the building envelope facilitate the widespread use of low temperature heating systems. Fresh air is supplied via window rebate ventilators. Controlled ventilations systems can be used and an air-conditioning system can be installed, on request.

Heating and Energy Systems

The floor plates are prefabricated from concrete with underfloor heating and screed. This means that, in principle, it is possible to cool the building in the summer via the underfloor heating system.

Heat pumps

Energy for heating and hot water is supplied by air-water-heat pumps, which are positioned on the roof in order to save space and for aesthetic reasons. An additional advantage is that the surface heating of the module floors can be used for cooling, when necessary.

Photovoltaic System

A specific photovoltaic system generates a large proportion of the power required for the air-water-heat pumps. The additional advantages of this system are its minimal maintenance requirements and long service life. Any electricity which is not required for the pump can be used for individual consumption.

Heat recovery

Traditional heating systems require flow temperatures of between 70 to 90 °C. Efficient solutions can be achieved at significantly lower temperatures (about 35 °C flow temperature). This method of controlling room temperature produces an especially comfortable ambience and feeling of well-being.

The benefits of wood

1. Longevity

The life expectancy of a building made of wood, is, depending on use, 60-100 years which is the same as for conventional buildings.

2. Construction site

Timber construction results in a low-emission construction site and largely dispenses with the use of water on site.

3. Room temperature

Controlled ventilation systems with 90% heat recovery give the building an optimal indoor temperature and lower heating requirements (optional).

4. Thermal insulation

The solid timber walls, clad with gypsum fibre boards, are permeable and therefore have a regulatory effect in addition to providing excellent thermal insulation.

5. Low maintenance

The facades and interior wall cladding of our buildings require minimal maintenance over the course of their entire life cycle.

6. Conversion

Buildings can be easily converted with minimal expenditure of resources or time. This means that buildings can be used for a multitude of purposes throughout their entire life-span.
