Hello dear forum members,
we are planning to start construction in summer and have designed a lovely little house with a well-known architect who was also willing to arrange the building permit for us. We have found a developer who has agreed to build the house based on our building permit. However, we were quite shocked when we received the cost estimate for the construction project. Unfortunately, we cannot explain how these costs can arise. Perhaps someone of you can tell me something about it. The plan is for a 2-story house with 153 sqm of living space without a basement, flat roof, clinker brick facing. Enclosed volume approx. 900 cubic meters. A garage 3.5 x 6 m, which will be attached to the house in exposed concrete, and a shed on the other side with wooden cladding (3x5m). Gas heating with solar thermal, controlled residential ventilation, underfloor heating. Windows are to be darkened with venetian blinds. A built-in fireplace. Plot is available. It should, if possible, achieve KFW 55 standard.
I planned 350,000 € for the construction, the developer's invoice amounts to 412,000 €, and in the invoice, he did not even include solar thermal and the fireplace. According to his invoice, the house only reaches KFW 70. Individual trades listed here:
Earthworks: 12,000
Masonry: 89,000
Carpenter: 8,500
Roofer: 23,000
Plumber: included in roofer’s costs (???)

Additional construction costs: architect 28,000, structural engineer 5,000, authorities 7,000, miscellaneous 4,000
Total price: 412,000
If I add solar thermal and fireplace, then I am at 450,000 € without the plot. We have an appointment with the architect next week to go through individual prices. But since we have no comparison values at all, I wanted to ask you.
What are your experience values regarding individual trades?
How high is the house supposed to be???
With 2 full floors, I estimate 10 x 10 m is easily enough to get 75 m² per floor. Typically, one floor needs about!!! 3 m height including intermediate ceiling and floor construction etc.
Below that, say about 50 cm for the base slab and insulation etc., and max. 1 m on top for insulation and roof... Then I would come to about 750 m³ !?!
If the architect calculates by enclosed volume, I would ask to see the plans...
Are walls included in the drywall? For us, the labor cost for drywall on the attic ceiling with a pitched roof!!! was about 2,000.- plus materials, which probably should max. be around 1,000.-...
