CONCEPT & IDEA

Two detached houses, each with a granny flat, designed according to the concept of the "living machine". Clear lines and simplicity take centre stage, without any superfluous frills.

 

Construction is based on the principle of simplicity, with compact floor plans that follow the tiny house principle and offer versatile utilisation options. The surfaces are deliberately left without elaborate and expensive coatings in order to focus on functionality and sustainability. Wherever possible, reusable building materials are to be used in order to pursue an environmentally friendly approach.

 

Sustainability

 

Thanks to the CO₂-binding timber construction method, the new building actively contributes to the reduction of CO₂ in the atmosphere. Particular attention is paid to the use of local timber from sustainable forestry. Instead of sealing the visible wooden surfaces, they are simply treated with natural oils. Gypsum fibreboards and plaster are coated with breathable silicate paints, which contribute to the natural climate control of the rooms thanks to their moisture-regulating properties. Heat is generated using a heat pump and distributed via underfloor heating. Domestic hot water is generated decentrally using instantaneous water heaters, which means that there is no need for energy-intensive heat storage tanks.

 

A large-scale PV system is planned on the 60-degree pitched roof surfaces. Thanks to the east-west orientation, consumption peaks in the morning and evening are to be covered. In combination with an electricity storage system and highly efficient, presence-controlled LED lighting, the aim is to achieve a self-sufficiency of around 60%. Rainwater is collected in cisterns and used for watering the garden and possibly for flushing toilets. The use of grey water for flushing toilets will be examined in more detail. These measures optimise the building technology and minimise operating costs.

 

The aim is to achieve CO₂ savings of over 50% during operation compared to conventional new buildings, which also enables the option of a KfW 40 building.T
