The German tradesmen are rightfully considered to be excellent and quality conscious. German building companies have earned an outstanding reputation over the last decades.

Therefore, it is even more unfortunate that many companies have to struggle for survival in the business world due to the constantly sinking building activity. (In the year 2008, 176,000 flats were completed in Germany. In 1995, the peak of productivity was reached with just less than 603,000 housing units, and since then the number of completed flats has decreased by more than 70%. Germany is at the bottom end of the scale with respect to housing construction Europe-wide.

In addition to that, there is an increasing number of lawsuits due to health impairments caused by pollutants and harmful odours. The appointed reviewers at court often end up deciding the case and as a concequence the building contractors are ordered to rectify the defects, rescind the contract, and/ or pay compensation.

Sentinel-Haus Institut  was developed with the help of medium-sized building industry firms and offers a number of advantages to building contractors who work with high quality standards.
