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

Irony? – I have the impression that you don’t understand part of the answers or feel misunderstood by those giving advice. Step by step, it’s becoming clear to me which thoughts guided your planning ideas. Uh-oh.

Apparently, the development plan for your plot specifies a fixed footprint limit of 80 sqm. You then planned a footprint 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 as a building setback following an old folk myth and thus came to a house width of 8 meters; the wall height is limited to 6.75 m, which you also exploited. However, with the ridge height of 9.475 m, the average height of the gable wall results in 8.1125 m (0.4h is therefore 3.245 m) – the house is thus 5.6 sqm too large in footprint and 24.5 cm too wide. Why hire a planner (and what is their profession?) if you only find this out at the building permit stage?

Then your application makes an extra round; meanwhile, the half-neighbors are effectively faster, you can no longer build first (a nasty trap called underpinning, especially if the neighbors want to build without a basement), and you lose the leading position in the house profile at the adhesive joint and might have to start all over again. Therefore, my urgent advice again: 1. Get to know the neighbors, 2. use a common planner as a coordinator; best of all, plan jointly and look for a common shell constructor. For this, I also advised reading the Goalkeeper thread (for those who don’t want to search: ) and gave the keyword “underpinning.” With this and “no basement” / “with basement,” you will find numerous threads where all this has already been explained in detail. Via my (external) post “A semi-detached house has TWO halves,” you may also find my personal advice, and the same source also has “With or without basement: a rule as a decision tool.” For this building, there is definitely no “thumbs up.” My posts on the topic of building for old age (another such naïve calculation stuff) can be found right next to it.
