ᐅ Housebuilding Company Isn’t Doing What I Asked – Feedback Welcome!

Hello forum community,

I would like to get your opinion on the following two issues. My house construction company is frustrating me.

Topic Patio Doors. In the approved planning documents, patio doors with a height of 2.32m (7 ft 7 in) were drawn in at my request. There will be no roller shutter above them, as the lintel is 25cm (10 inches). The patio doors will be made of white uPVC, with soundproof glazing rated at 39dB, RC2N security class, and triple glazing. The width is not a problem, approximately 85cm (33 inches) each. However, the height is an issue. I contacted the window company (hired by the construction company) to ask if the height was a problem. I was then told that only patio doors up to a maximum height of 2.26m (7 ft 5 in) can be installed. After early consultation with the construction company, I was verbally assured that the height would not be an issue, and if necessary, the window company could be changed. The selection appointment took place at the above-mentioned window company in the good faith of the site manager, believing that the taller patio doors would be installed. At the selection, the window company took the position that only 2.26m (7 ft 5 in) high doors would be installed, stating no other company installs patio doors that large. The site manager also tried hard to convince me to accept the 2.26m height. After consulting four other window companies, all confirmed that the dimensions I requested would not be a problem, as the door weight is calculated and not just the height alone. Now I want the windows and doors credited back to me so I can handle it myself. Alternatively, could I insist on the patio door dimensions from the approved planning?

Topic Interior Walls. Around the guest bathroom on the ground floor, two walls were planned with a thickness of 17.5cm (7 inches) by the architectural firm as a precaution for structural reasons. The "main wall," located elsewhere and bordering the living room, was also planned with 17.5cm (7 inches) thickness. However, I would have preferred the walls around the guest bathroom to be 11.5cm (4.5 inches) thick to avoid a cramped bathroom and to provide more space for the refrigerator in the adjacent room. I informed the construction company of this before submitting the building permit/planning permission application, again at its submission, and once more shortly before permit approval during the shell construction selection appointment, asking that the static calculations use 11.5cm walls around the guest bathroom. I was told it was not a problem. Apparently, the structural calculations were commissioned only after the permit was granted. One month later, the construction company informs me that changing the guest bathroom wall thickness from 17.5cm to 11.5cm is no longer possible because the structural calculations and precast ceiling planning are completed and cannot be changed. Do I have to accept this nonsense?

Best regards
