Hello everyone,
I’m new here. I’m near the end of my house planning and wanted to double-check if my cost calculation looks correct, or get your opinions on it. I gathered the prices myself (partly by getting quotes, partly by searching online, partly by talking to people).
Facts about the house and land:
Plot size: 808m² (9748 square feet) – already owned
Living area: 180m² (1938 square feet)
Double garage (extended to 9m (30 feet) to gain an additional parking space)
Double garage with basement
2 full floors
Hip roof
Location
Site setup: €1350
Earthworks: €6436
Sewer works: €1837
Reinforced concrete work: €45599
Masonry: €36609
Insulation: €4318
Plastering: €22966 (interior and exterior)
Heating: €25000 (air-to-water heat pump + underfloor heating)
Tiled stove: €13000 (as a room divider between dining and living room)
Ventilation system: €8000 (central)
Electrical: €8000
Floor coverings: €17000
Painting: €5000
Sanitary installations: €13000 (including fixtures)
Windows: €21000
Doors: €18000 (interior doors, front door, garage door)
Kitchen: €15000
Outdoor work: €8000
Roof: €10000 (calculated only for timber and roof shingles; I will do the rest myself :cool
Net total: €284,532.40
VAT: €54,061.20
Grand total: €338,594
What do you think? Does this look reasonable?
Thank you very much!
Kind regards,

If you read more on the HBF here, you will find that I am essentially correct regarding the actual construction costs of a single-family house—provided users share their related experiences openly, of course.
Most homeowners—apparently including "Baufie"—divide the total cost by the sqm of living space; this is incorrect. On one hand, a house can be occupied without a double garage, and on the other hand, typical additional construction costs should not be included in the price per sqm of living space!
Kind regards
Massivhaus85 schrieb:For the house alone at an average standard and quality as a KfW 70 energy-efficient house, the cost is €1,500.00/sqm (square meter) of living space. Then you add the technical equipment or heating system—in your case, the stove—and the basement-equipped double garage. The figure for a single-family home "lags behind" in the sense that this value decreases as the living area increases. At the same time, it allows some flexibility, and homeowners are pleased if the final cost turns out to be lower; however, a reliable financing plan should not underestimate this price per sqm of living area—there is nothing more expensive than refinancing!
@Bauexperte: what values are you using? There are more than just a handful of values.

Massivhaus8527 Nov 2012 21:37According to the gross volume calculation, this is the result:
For a house with medium specifications without owner participation, the cost is calculated at €280 per cubic meter (cbm). For the garage and basement, it is €80 per cubic meter (cbm).
House 882 m³ (31,144 cubic feet) x €280 = €246,960
Garage 535 m³ (18,893 cubic feet) x €80 = €48,060
Total: €295,020

According to gross volume calculation, this is what you get:
For a house with mid-range finishes and no self-construction, the estimate is €280 per cubic meter (cbm). For the garage and basement, €80If you only make the rooms tall enough, then it should work out... I would guess from about 5 meters (16 feet) upwards...
Who exactly does "one" refer to, and what is supposed to be included in these costs? Turnkey?
