Already sanded and primed, the largest sections are checked against one another. The rear wall of Bon Marché is MDF and the sides and front (which I've already covered) are of plywood. Because of their different manufacture, MDF and ply are not guaranteed to remain dimensionally stable in relation to each other, something I discovered as we got on to the next stage.
After laying the back and right-hand wall panels horizontally, at right-angles to each other, we began to prepare the floor sections for final fitting and gluing (but not actually gluing because the decorating is still to be done).
Like the rear wall, the floors are cut from MDF and their tabs fitted the slots on the back without any difficulty. However, the slots in the plywood side were too narrow - only by something less than 0.5 mm - yet just enough to resist the necessary snug fit. The plywood had shrunk while the MDF had not, but it could be remedied by shaving the ply down one side of each slot with a sharp Stanley knife (an ordinary craft knife or scalpel blade would not be strong enough).
In the end, all the floors were pressed firmly in place and squared up.
Keeping the carcase on its back, I experimented again with swapping interior walls between Floors 2 and 3 (SeeThink electric, 19 October 2012). Fortunately the height of the rooms is the same on both floors.The result of the swap is a full-depth living room on Floor 2, visible through the side opening in the left-hand wall (see first photo). And each bedroom on Floor 3 gets its own door. Win-win!
First, I took the walls from Floor 3 to Floor 2 where I plan to have a kitchen next to the living room. The smaller room was too narrow and I have moved the party wall a little over to the left so that the kitchen is now big enough for Charlie and Frankie to eat in, as well as cook. It will also be separated from the stairs and landing by a half-glazed partition, a very common solution in those days to making extra room space in old houses.
And this is the living room viewed from the side. I'll block up the old connecting doorway with a chimney breast and fireplace. The new door onto the landing gives access round from the kitchen and also up the next flight of stairs to the bedrooms.
Up on Floor 3 I had the same problem with the smaller room being too narrow (beds take up a surprisingly large area, I find). So here too, I've moved the party wall and made enough space for a wardrobe.
This shot shows I've kept the dividing walls in a vertical line. By the way I hope you'll excuse the rather crooked, fuzzy photos, they were taken sans tripod from the top of a small step ladder. The house was lying on its back and the interior walls were propped up on Lego bricks. It was an all-round balancing trick!
Here's some 'new' vintage caboodle to finish with:
I'm so pleased with the F.G.T & Sons gas fire, I've been chasing one for ages and to get the pale blue version is a real bonus. This is ideal for the lodger's room, now I'll have to make a coin-in-the-slot meter to go with it. The bread bin and slop pail aren't vintage, they're just awaiting 'the treatment'.
