A house stone or a dome bench is a large stone block that the stonemason serves as a base. Outside of the technical language, the stone lying on top is also called house stone, especially after completion and at the place of final use.

For this purpose, a natural stone is selected that is no longer used as a stone due to defects. The stone processing base is usually embedded a few centimeters into the ground so that it guarantees a secure stand. A workpiece is benched on a hooded bench so high that a stonemason can lay the flat of his hand on it. The arm is stretched out and not bent. So-called bench wood can be placed underneath for height adjustment.

In the manual processing of a rough stone into a stone with flat surfaces, the lowest point of the surface to be produced is determined after the bench and the first edge stroke is drawn using a hammer and iron . In the meantime, however, hand-held pneumatic hammers are also used. However, nowadays, with the exception of monument conservation stone restoration, flat surfaces are mostly created using stone saws .

Wooden or welded metal trestles are also used as hood benches. The dimensions of the house stones or dome benches are quite different, but they are usually around 50 to 70 cm high, 50 cm long and 50 cm wide.
