ᐅ Improvement Suggestions for a Single-Family Home with 137 sqm of Living Area and a Secondary Apartment

Hello

First, clarify these points before you start working on a design that might not fit. Once the basic data is certain, share it again, and then you will receive constructive suggestions.

preferably

This is not fixed.
For example, if you choose 1.40 meters (4 feet 7 inches) with a 35-degree angle or so, you have more flexibility.
But that also depends on the floor area.
I would, for instance, move the guest room upstairs to a spare room (next to the empty suitcases).
So: a storage room on the ground floor is really good, your mother-in-law can use part of it. Then she doesn’t need to use the stairs to the main living area.
May I ask what the symbols in the bathrooms mean?

To summarize: the plot is free of developer restrictions, but it is apparently being sold by a development company (possibly closely linked to the local authority?), and they want to know at the time of sale how you plan to build on it; their idea of uniformity is reflected in the 115 cm (45 inches) knee wall height.

Actually, I was roughly satisfied with the floor plan and only wanted advice for or against a construction company.

In the end, hopefully you are glad that you are not being led into a trap here. A construction company usually will not send a client away empty-handed if they see a chance to get a building permit—and unfortunately, that chance would exist: the building authority wouldn’t care about your hand-crafted interior wall corners, they would give their approval to anything that formally meets the regulations. Decision made and announced: the client may be unhappy; and the builder will put a price on it. Then the bank says the price fits your creditworthiness, and you, unlucky one, might even be happy for the moment. Because neither builders nor building authorities employ counselors who would try to prevent such fates. And afterwards, someone stands in their poorly finished house and can’t believe experts did not warn them. But that is not their job. The contractor also has mouths to feed, and the building permit officer feels citizen-friendly by not opposing a building request, even if it challenges their own doubts, as long as it is legally approvable. Have we at least shaken your confidence enough by now (so that you understand why)?

As I understand it, the zoning plan clearly indicates that the framework is larger; but the seller can still choose someone else if, instead of the more favorable small house, the allowed framework is more fully utilized. However, I also think that even with a more skillful design, this is something you should not dismiss lightly. The apparent contradiction between one-and-a-half- and two-story buildings is probably due to the special feature of the full storey definition in the Berlin-Brandenburg region.

First, I would like to briefly thank you; I find it more than remarkable how much time you are dedicating to my concern.

For example, if you take 1.40 m (4.6 ft) with about 35 degrees or so, you have more freedom.
But this also develops with the floor area.
I would, for example, move the guest upstairs to a spare room (next to the empty suitcases ).
So: storage on the ground floor is already great; then your mother-in-law can use some of it. She also wouldn’t have to take the stairs to the basement.

Yes, I feel the same way about the stairs to the attic; my mother-in-law is not getting any younger... who knows how long she can still manage going up there without problems.

In the end, hopefully it pleases you that nobody here lets you walk into this trap. A construction company usually won’t send a co-client home empty-handed if there is a chance to get an approval stamp—and unfortunately that chance exists: the building authority wouldn’t care about the overtime needed for your hand-carved interior wall corners; they would check off anything that formally complies. Decided and announced, the client may be unhappy; and the builder puts a price on it. Then the bank says the price matches your creditworthiness, and you unlucky one would at least be happy for the moment. Because neither builders nor building authorities employ counselors who would prevent such fates. Afterwards, someone stands in their finished botched building and can’t believe that professionals didn’t warn them. But that’s not their job. The builder also has mouths to feed, and the permit officer feels citizen-friendly by not opposing an approval-worthy building wish that also makes them shake their head. Have we at least now unsettled your satisfaction (so that you understand why)?

As I understand it, the development plan clearly states that the framework is larger; but the seller can still decide for someone else if instead of the preferred “fairy-tale cottage,” the allowed framework is more fully used. However, I think this should not be dismissed lightly even with better planning. The apparent contradiction between one-and-a-half and two floors probably lies in the particular nature of the full story definition in Berlin-Brandenburg.

That’s exactly right, the plot seller belongs to the city and they require this knee wall height. The submitted plans are included with the purchase contract.

Where did you find this draftsman? I can hardly believe that he actually studied architecture seriously. Given your fairly high demands, I definitely wouldn’t save money by going without a skilled professional who truly deserves the title of architect.

Please do not provide any further answers and then say, I already told you that. Summarize, and then we can work with just a few corrections if necessary. This approach doesn’t work.
