For the tiles, a price of 24.90 per m² was taken as the standard. We have already looked around in the tile shop, which is the partner of the construction company, and you should be able to get by well there. The advantage is that Villeroy & Boch is practically just around the corner, and as a very good customer, the store often gets second-choice tiles at bargain prices. The second choice refers, for example, to the fact that the color requested by Villeroy & Boch is not 100% matched, but otherwise there is no defect on the tile. They also showed us a few examples of what would be first and what would be second choice tiles; sometimes you can't see any difference at all, and for one tile, we even liked the differing color better. According to insider information, the store gets these special items sometimes for under 10.- while the list price (for the first choice) is often well over 50.-. These tiles are then usually sold for 20-30 euros, i.e. roughly in the calculated range. Apart from that, a large part of the tile costs, often the larger part, consists of laying including materials. The bathrooms will (of course) be tiled up to the ceiling, which I also like best. Only in very small guest WCs of maybe 3m² would I tile only halfway up, as otherwise it can quickly create a oppressive feeling. Aren't new garage doors always sectional doors? At least we have never been offered anything else. We have the double-walled (i.e. insulated) door with M-rib. The stairs are probably from Fuchs, definitely from Germany, but the standard model is beech without any frills. Regarding the roof tiles, of course, I thought you could choose the shape and color, coatings cost extra. However, even though that probably has advantages, I somehow don’t like such a shiny roof. For us, it will simply be matte anthracite. Normal electrical equipment means about 80 sockets (the basis is about 45-50) throughout the house, the larger fuse box, the significantly increased number of CAT and satellite connections including a Fuba dish, about 25 built-in spots, 6 electric roller shutters, a few more light outlets in the stairwell (wall torches), stainless steel intercom system (not a cheap Bticino) with 2 indoor stations, a few dimmers, etc. So clearly more than, for example, in the Town & Country standard house, but no KNX, sound or anything else...
