A renovation costs from around €700/m2, which of course is the option with a lot of own work and simple standard and not everything completely. Let's say you don’t want to do anything yourself, etc., then I would calculate around €1200-1500/m2. The extension is of course extra, that’s then new construction, accordingly certainly more expensive. Our house has 100m2 and we did almost everything inside and little outside, so no facade, no roof, heating boiler still okay. Floors, ceilings, walls, electrics, most windows and radiators, roof insulation, drywall, tiles, rough installation, new radiators and pipes in the attic… some done by companies, some ourselves, that brought us from 2017 until now for simple standard about €550-600/m2. Let’s say we would now also do heating boiler, roof, facade and the remaining things at once… we would spend a good amount of money again, coming to €1350-1500/m2, then the house would really be finished and I think I calculated generously. With company prices. It really depends on what you want. If you ultimately want something like a modern new building with all the modern amenities that almost everyone provides in new construction nowadays, then it will just be more. But with that money and good calculation you can manage well. But then a new build would also be more expensive, and significantly so, you basically can’t get below €2000/m2 anymore and the better it is, the more expensive, with new builds you quickly reach the prices called for by the architect. Selling these for an old building renovation is almost ambitious…
