Floor Plan Check Semi-Detached House - General Optimization + Storage Space

Good evening everyone,

first of all: I think the missing doors can be explained because we sent the plans back and forth. In the first plans, they were included. As far as I understood, the building permit is mainly about complying with the building window, etc., and interior adjustments can still be made as long as the load-bearing walls are not moved.

Regarding the room concept: we have two small children and would like to plan for old age as well. That is why there is a bathroom on the ground floor; if we live there when we are older, the living room could also be separated into a bedroom. About the upper floor: while the children are still small, they should sleep with us on the upper floor, and we use the attic as a home office and guest room in the meantime. Later, they should move to the attic, and we can enlarge our bedroom and use the other room as a home office. I find the utility room on the upper floor very practical; I know it that way from my friend and think it’s great. Regarding the indentation on the upper floor and attic: I don’t need a balcony on the upper floor, but the development plan states that we are only allowed a building window of 80 sqm; however, nothing is said about the floor area ratio. Nevertheless, I assume that we must adhere to the 80 sqm on each floor, but I need to tell the architect to ask the municipality about this.

There is also a guest room in the basement. We are having connections for a bathroom installed in case we have some money left over and want to install a sauna there.

Best regards

Nevertheless, I suspect,

Floor area ratio and plot ratio are maximum values and not exact ones. I can only advise taking three steps back and starting at -3 to learn, gather information, absorb principles, and then also learn to communicate with an architect.

All right, thanks for the valuable input.

Irony? – I have the impression that you do not understand part of the answers or feel misunderstood by those giving advice. Gradually, it is dawning on me what thoughts have guided your planning ideas. Uh-oh.

Apparently, the development plan for your property specifies a fixed floor area limit of 80 sqm. You then planned a floor area of 85.6 sqm and (unfortunately naively) thought you could subtract the cut-out terrace corner from that. From a plot width of 11 meters, you apparently subtracted 3 meters of building setback according to old folklore, arriving at a house width of 8 meters; the wall height is limited to 6.75 m, which you have also fully utilized. However, with a ridge height of 9.475 m, the average height of the gable wall amounts to 8.1125 m (0.4h is therefore 3.245 m) – thus, the house is 5.6 sqm too large in floor area and 24.5 cm too wide. Why hire a planner (and what is their profession?), if you only get caught out at the building permit stage?

Then your application will have to go through an additional round, meanwhile the neighboring half-plots will likely be faster, you will no longer be able to start building first (a nasty trap called underpinning, especially if the neighbors want to build without a basement), and you will lose the leading position in the house profile at the bonding edge and probably have to start all over again. Therefore, once again my urgent advice: 1. Get to know your neighbors, 2. hire a joint planner as coordinator; ideally, plan together and find a common shell construction contractor. For this, I also recommended reading the Goalkeeper thread (for those who are too lazy to search: ) and gave the keyword "underpinning." With this as well as "without basement" / "with basement," you will find numerous threads where all this has been explained in detail. You might also find my (external) contribution "A semi-detached house has TWO halves" helpful for my personal advice, and at the same source you will also find "With or without basement: a rule as a decision tool." For this type of construction, there is clearly no "thumbs up." My contributions on building for old age (another naive calculation) can be found right next to it.

And what if there isn’t one? Why should you write down something that doesn’t exist? The biotope also remains unmentioned, because it doesn’t exist. You can’t complain about that, can you?!

I am missing the information because it is in the questionnaire.

I miss the specification because it is in the questionnaire.

There is no slope. What is meant by biotope? The soil survey resulted in class 4.
