Abstract: The invention relates to a method for assembling a wall (1) of a desired wall thickness from panels (2) and at least one stile (5) connecting the panels (2), comprising determining the dimensions of the connecting stile (5) in wall thickness direction and subsequently arranging at least one recess (3) receiving the connecting stile (5) in each of the panels (2) at a chosen distance (D) from the visible side (8) thereof, wherein the distance (D) from the visible side (8) is determined from the desired wall thickness and the determined dimensions of the stile (5) at the position of the join. The invention further relates to a system for assembling a wall (1) provided with at least two panels (2) each having at least one recess (3) at a determined distance (D) from their visible side (8), and at least one stile (5) having flanges (4) co-acting with the recesses (3) for mutually connecting the panels (2) and having determined chosen dimensions in wall thickness direction.

Abstract: A building construction includes a slab-like floor layer having an upper surface defining a habitable area and at least one horizontal groove opening into the lower surface of the layer, a plurality of duct-like parts being supported on the upper surface of the floor layer in accord with an arbitrarily selected room layout, utility lines for the habitable area being disposed in the horizontal groove in the lower surface of the layer and also being disposed in the duct-like parts above the upper surface, and partition walls being disposed atop the duct-like parts to form rooms.
