Yvonne, one can argue about one thing or another in your list on page 1, but basically it is correct. Those who build without a basement simply need a storage room elsewhere. Even rental apartments usually have a bike cellar or something similar. Therefore, a vacuum cleaner dungeon under the stairs will not suffice. My idea has always been: make the utility room big enough for the washing machine etc. and for supplies. Use external rooms for garden and hobby, in our case garage and metal shed. Use the attic space sensibly instead of a basement and make it comfortably accessible. For us with stairs instead of a hatch and ladder. Otherwise, you will end up in chaos. The cost side. Extra charge for insulated attic with stairs and fully walkable. 14 thousand gross. Biohort shed, 1500,- with foundation. Prefab garage electrified and with side door, painting EL, roof parapet as well. 8000,- So that is almost 25 thousand euros gross for these ancillary rooms, which we certainly do not want to miss. All our winter jackets are now up in the attic. There are the travel suitcases. The old, still intact Philips vacuum cleaner, some boxes with Christmas decorations etc., some tools from me for the house, most of it is in the garage. The model railway layout. In the garage the bikes, in winter garden furniture and beach chair, spade, rake, cultivator etc., bark mulch and flower pots, paints and tools. In the Biohort gasoline and mower. And much more.
