Future-oriented without surface sealing!

Increasing land sealing represents an ecological challenge that can be addressed through innovative, climate-friendly construction methods and the use of fallow building plots. The Heise houses, which combine minimal land use and reusability of foundations, offer practicable solutions to reduce environmental impact and promote sustainable urban development. This approach represents an important step towards ecologically and economically beneficial living concepts.

Future buildings without surface sealing as relief for the environment

Our vision is to create future-oriented solutions that minimize surface sealing. According to a study by the BBSR from 2013, 15 m² to 20 m² of interior development area per inhabitant can be empirically proven, while around 3.5 m² of new land use per inhabitant and year are currently recorded. The majority of the municipalities surveyed assume that brownfields and vacant spaces can be activated in the short to long term.

In many German federal states, groundwater levels have fallen sharply in the last 10 years, and the effects on nature and the environment are alarming. Thousands of urban trees have dried up and more than 500,000 hectares of forest have been lost due to lack of water — almost double the area of Saarland. Even the levels of the major rivers are visibly falling, and some newspapers report alarmingly on the situation.

Our answer: Climate-friendly Heise houses

With our climate-friendly Heise houses, we are helping to address these problems in a significantly reduced way. Our houses only require around 6 percent of the area of a conventional foundation, as we can dispense with flat concrete foundations. Instead, we rely on point foundations, such as screw foundations, which can be removed and reused when the modules are moved or dismantled.

Use of fallow building plots

Our houses offer not only ecological but also economic benefits. The simple dismantling of our modules is of interest to property owners who can make their previously fallow building plots available to the market as leased properties. After the lease period, the property can be returned to its original state quickly and cost-effectively without losing value.

According to the BBSR study mentioned above, up to 2 million fallow plots of land could be available for residential use in Germany, Austria and Switzerland. This development could significantly alleviate the burden on the housing market and at the same time counteract the trend towards land sealing.

Our vision is to develop and sell “Villages” holistically according to the Heise Haus principle in order to make a positive contribution to sustainable urban development.
