Hello everyone,
after my "plan" for a new build drifts into the distant future due to various factors, I am now planning to extend my existing house and am trying to get a rough overview of the costs.
The existing house has a ground floor with approximately 90m² of living space and an extension of about 70m². My parents live on the ground floor and will stay there (in case anyone gets the idea to say "just swap"). The old building has a basement. On the upper floor of the old building there is basically the same apartment again (that's where I live).
The extension was planned 20 years ago so that it would be easy to add another floor. So as far as static loads are concerned. The roof "only" has to be removed, the ring beam in the rear part raised by about 1.5 meters, and a corresponding intermediate ceiling inserted. No additional support columns or anything like that are necessary.
The new extension should include a bathroom, the kitchen, a living/dining room as well as a balcony. Possibly a bedroom instead of the kitchen, though then the kitchen would have to be placed in a room in the old building where there are no connections – and I didn't really want to tear up the entire old building. The new bathroom could be connected to the existing pipes using a core drilling, so minimal destruction would occur.
I asked an acquaintance with architectural "skills" what I should expect in terms of costs. He said an extension is basically like a new build, and I should expect about €1800 per m² of living space. Is that realistic?
How would you roughly classify the costs for the following points (in parentheses my layman’s estimates):
Ring beam masonry (€2,000 with own work)
Inserting intermediate ceiling (€20,000)
New build masonry (€10,000 with own work)
Windows (€20,000)
Roof including facade (€30,000)
Sanitary including bathroom and underfloor heating (€20,000)
Building services (electricity, network,...) (€8,000 with own work)
Flooring, walls, wooden ceiling (€15,000 with own work)
Additional costs (€15,000)
Total: €140,000
Does this sound realistic? Or is something estimated far too far from reality?
