The project of building a doll's house continued with the choice of materials, and then the definition of the room sizes and measurements, which are needed to cut the wood. For the outer walls I chose standard plywood of 12 mm thickness, and 9 mm plywood for the interior walls, the floors, and the roof.
Thus the 12-mm ground plane onto which the house is built, is 420 mm by 842 mm. Forty-two is for some reason always a welcome size. Centred on this there are the outer walls, of which the left and right walls are of 12-mm plywood and the rear wall is of 9-mm plywood. The outer dimension of the doll's house is 360 mm by 782 mm.
The room sizes were chosen such that the bigger room (living room) is 330 mm by 351 mm, which is equivalent to 3.96 m by 4.21 m. The staircase is 160 mm wide (1.92 m), and the smaller room is 250 mm (3.00 m) wide.
Note further, that also the 12 mm walls were grooved with a 5 mm deep and 9 mm wide groove, into which the rear wall fits. See the detail photograph to illustrate this.
Since the horizontal dimensions are fixed now, also the size of the two floors/ceilings is fixed. These should slot into the side walls and into the rear wall. The grooves are 3 mm deep, and therefore the floor material has to be cut to a size 6 mm wider in the long direction, and 3 mm wider in the narrow direction than the internal width of the doll's house, i.e. 764 mm by 354 mm.
Next step was to think about the exact shape of the roof and thus the wall underneath. This included the invention of a hingeless opening mechanism for the roof. More about this in the next blog post.
