A building system in a residential building, with a skeleton structure including posts (14) and crossbeams (24) erected on a ground slab (9), the skeleton structure defining skeleton fields between posts and crossbeams and wherein the skeleton fields are provided with filling panels (10), windows (12) and doors (20), and wherein

• the filling panels (10), which are designed in multiple layers with an inner cover plate (17), an outer cover plate (16) and edge strips (29) running between the inner cover plate (17) and the outer cover plate (16) with an insulation (15) enclosed between them, are arranged substantially in alignment between the posts and crossbeams,
• each one of the posts (14) or crossbeams (24) are formed to have a T-shaped cross section including a flange and a web, the height of the web corresponding to the overall thickness of the insulation (15) and the inner cover plate (17) of the filling panels, and the flange (43) of the T-shaped posts (14) or crossbeams protrudes on the inside of the building over edges of adjacent inner cover plates (17) of the filling panels (10) so as to retain the filling panels in place, the outer cover plate of each filling panel has an outer edge that overlaps the web of adjacent posts (14) or crossbeams (24) at least in part,
• connecting means (30) are provided at the posts or crossbeams for connecting the posts (14) or the crossbeams (24) to the filling panels (10) located in the skeleton fields, said connecting means being formed as releasable fittings, wherein the connecting means (30) clamp the regions of the outer cover plate (16) that overlap the posts (14) or crossbeams (24) to the web of the posts (14) or crossbeams (24), and
• the building system is designed so that it can be disassembled.
