When a corner is cut and there is no space to build on it, the foundation (bunyaad) is joined underground to complete the regular shape. The current then flows in the full shape, so the cut above ground causes no defect.
When a beam over the bed cannot be avoided, paste plywood, wood or thermocol on the underside of the beam.
It is the structure built below road level when a house is first dug out: the foundation, also called neev, bunyaad or daasa. The plot's shape is read from it.
Yes. If the beam and the foundation are cut, the plot is considered cut. What a cut is will be explained further with a model.
From the foundation: the outline of the foundation and plinth beam of the outermost walls, joining all the corners into a square, rectangle or other form. The geopathic current under the ground runs in that shape, so projections above ground do not change it, while an irregular foundation stays irregular even if right angles are built above it.
