As an experienced company in timber construction we are a member of the “Gütegemeinschaft deutscher Fertighausbau (GDF) e.V.” (German association of prefabricated builders). The “GDF” gives the RAL seal of approval to companies which by regular quality checks of independent institutes prove their high standards regularly.

All materials introduced by Engelhardt-house are therefore fully documented and are subject to strictest criteria of independent experts. The production of the components is strictly monitored and, through the award of the so-called Ü-mark on all parts, transparently documented for the building owner. We from Engelhardt-house undergo this quality assurance by independent experts every six months. Thereby we guarantee you an execution according to statutory safety and building standards as well as according to all rules of craftsmanship.

That‘s whate the RAL-seal of approval RAL-GZ 422 „Holzhausbau” (timber house construction) stands for.
