This is part five of a personal carpentry project whose stages were recorded on video: building a cat house for our two kittens. Here are the other parts:
In this video, you can see the almost-finished bottom, where the 3 cm thermal insulation has been laid against the bottom part of the floor and secured to it by wooden planks and wood screws. The bottom beams (the ones belonging to the frame) have already been treated with base (against mildew and rot), and the interior has also been treated with base at this point. The bottom still needs to be caulked properly at the edges of the thermal insulation, then stained and treated with wood wax/varnish.
