BV single-family house with full basement

In fact, it is very often the case that no plots of land are available at all. They then either offer you the very last junk or plots that have already been sold. Read carefully what happens if a plot of land is offered to you and you refuse or the purchase does not go through! Usually, penalties are incurred.

It is rather unlikely that someone will search for or even find a suitable plot of land for you. Maybe a good real estate agent - but even they only have the things nobody wants. If you do not take action yourself, it would have to be a great stroke of luck.

What is included in the base house price? Have you signed?

Not signed yet. The house would be ready to move in on the ground and upper floors, basement as stated without floors/paint. The base house price includes, among other things, electric blinds on the ground and upper floors, complete bathrooms, chimney, BDT, soil survey, architect, etc.

Sorry, but if you were to sign a contract at this point, then there really is no help for you anymore.

Kitchen and guest room are incredibly narrow, that won’t work. Where is a bed with 1.60m width supposed to go in the guest room? Doesn’t fit! If a living (hobby) basement is planned anyway, why so complicated through the hobby room into the study? Does 3m2 really matter in the basement or can the hallway not be made a bit more livable?

Thanks, that’s how we see it too. Going through the hobby room into the study doesn’t bother me. If it were possible otherwise, of course that’s also fine!

In the basement/hobby room it doesn’t matter a few m2, but the room must not become “tube-like” and must remain rectangular. I know, a bit crazy, but necessary. The hobby room could of course also be “rotated,” I don’t care, as long as the dimensions are right.

Hallway noted… probably actually a little narrow.

Calculated are:
Base house price 415k
Additional construction costs 35k
Land 200k
Acquisition costs 35k

Completely unrealistic? Personally, the costs for the earthworks worry me the most, because I suspect the biggest cost driver there with the "wrong" plot of land.

The calculation lacks any buffer for upgrades, outdoor facilities, furniture/kitchen, carport or garage

I always find it baffling how one can assume to estimate the costs so accurately at such an early planning stage.

How is it actually with this potential quasi property developer situation: Is it ensured that at the end, real estate transfer tax does not have to be paid on both the land AND the house, if the BU is significantly involved in the acquisition of the land?
