There were times when people were content with 130 sqm or less. The guest would spend the night in the cleared children's room, and the office was set up at the dining table or in the bedroom niche. Or you went to the office. I don't know that anyone is forced to work from home. Then you simply don't have a position for the tax return. You don't have to forcibly deduct everything that others do.
I am a software developer, and working only with a laptop is unfortunately difficult for me, so I can't just "set up my office on the kitchen table." My employer is unfortunately 850 km away, so just driving to the office is not an option. My wife is a teacher, and unfortunately, there are no workspaces for teachers at her school either. Regarding the rooms, it's more that we want to keep the option open whether we might want 3 children after all, which would mean we would have to share the office accordingly. So the number of rooms is definitely fixed.
Current turnkey price for a Town & Country Flair 152 RE, in a mid-price region like Hannover, by the way, from 272,500 EUR.
In my city, the price starts at 340,000 EUR.
For us, including land and all additional costs, it’s about 577,000€ for 155 sqm. Since we are not building turnkey/ready to move in, the price is reduced to 529,000€ (including materials). The land (purchase price only) is 72,000€.
Who are you building with? And what are you doing yourself?
I also called some local construction companies, and as a guideline, they said houses with 6 rooms turnkey, ~150 sqm, two full floors, and standard equipment including incidental construction costs (but excluding house connection costs and building permit) start at 380-400 thousand EUR. So probably including connection costs and building permit at about 420 thousand EUR? If you do a lot yourself, then probably somewhat cheaper. So as it sounds, with the land included, 500 thousand EUR total will be rather difficult. But doable with 550 thousand EUR. That would probably still be within our range. We would then add the outdoor facilities and carport later. Right now, it’s all just theoretical anyway since we don’t have land yet. But thank you for your estimates.
