Changing floor plans of model houses from the catalog - additional costs?

Hello!

Completely freely planned is currently rather not an option.

Why not? With your change requests, a "standard house" doesn't necessarily have to be cheaper.

We want to turn an open kitchen into a closed one.

That is usually the least problem. However, you should make sure that the kitchen is still sufficiently large.

We could quite well imagine a sample design if the house is built 2-3 meters larger to the left, so that the corresponding rooms adjacent to the left outer wall become accordingly larger.

That requires new statics and changes to the entire construction. From my experience, some "catalog providers" have a grid in which the house can be widened by one or two meters. I didn't even inquire about three meters back then. Usually, providers prefer it if you only move interior walls.

Every provider advertises that the catalog houses are just ideas and that every house can be redesigned. But what does that look like in terms of costs? So far, our impression is that they are rather reserved?

With a widening of three meters, it is definitely a five-figure sum. At an assumed width of 8 m, that means 24 m² more.

Installing a non-load-bearing wall surely won't cost the world, but enlarging a house regarding the outer walls? Do you have to reckon with huge sums or are we still talking about a four-digit range?

Why don't you just ask the provider non-bindingly for a rough price indication and the building service description of the house you have in mind (with the widening)?
You can't rely on catalog prices anyway. You will be wiser after that.

We built with a provider (Holzständerbauweise) who designs/builds all houses individually. That this will ultimately have to be paid for somewhere is, I think, clear. With most other providers, however, we had the feeling that aside from the standard houses, a considerable surcharge is immediately due.

Thank you very much for the numerous responses.

Statics will probably be the problem; the roof will then also have to be bigger immediately... ah, it’s not so simple.

So far we thought (no idea about construction, not very flexible in terms of time, we want to have everything from a single source as much as possible) that a larger provider can probably handle that better and calculate costs more fixedly than an architect who plans freely at first and then individual trades are assigned. For us, a fixed price calculated in advance for the house would be important, and we probably won't manage that with a freely planned house.

An initial consultation with an architect is of course also an option.

Of course that is possible, I knew from the contract signing until the building handover which amount I had to pay.

I built with the architect and general contractor who went completely in advance.

Our payment plan was as follows.

5% down payment
Entire basement after completion

Remainder after building handover.

Hi,
why on earth should a BU have such a hard time planning a house the way you want? Sure, it will quickly become more expensive than the catalog houses, but less because of the statics (which anyway have to be "calculated" and submitted for every house. Even if he pulls them out of a drawer, you pay for them!) but rather because with a free design one tends to plan a bit more elaborately. That then becomes more expensive.

If you only want to enlarge the house a bit, but not really build more elaborately, you can roughly scale the catalog prices, so with 10% more living space, you can assume about 10% more cost.

Best regards,

Andreas
