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,

I’ve already found my way around.
Yes, I have thoroughly researched and considered the heating issue.
A friend of mine is a heating engineer, and he ultimately convinced me.
There are many calculations out there... Heat pumps are cheaper than everything else, and also vice versa.
What matters to me is whether I have considered all the important aspects.
I don’t want to be surprised later. It’s clear that prices can range from cheap to expensive everywhere.
It should be mid-range, no excessive luxury.
Can I realistically expect this price based on my information?
Regards

I will build the basement as a waterproof concrete shell anyway. (There is no additional charge from the builder, as they construct every basement this way.)

(There is no additional charge from the builder; they do every basement like this) My plot was also "fully serviced," likewise in a new housing development. However, the city still charged a proportional sewer connection fee of about 2400 Euro. (This had NOTHING to do with the actual connection costs!) Additionally, as I fortunately did not have to deal with, most others had to bear the cost of creating an inspection chamber (around 2000 Euro, two required since rainwater and greywater are separate) and the sewer works from the house itself (redirecting gutters from the back to the front, etc.; for me it was 2900 Euro). So, budget a bit more for sewer-related work. However, you should definitely take another look at the internal doors. How many doors are planned?

Additional construction costs: €30,000 (EUR)
Reserve for extra foundation costs: €8,000 (EUR)
Painting/flooring work: €15,000 (EUR)
Outdoor facilities: €15,000 (EUR)
Reserves for extras: €10,000 (EUR)
This results in a total investment of €434,500 (EUR) for a medium standard, excluding land costs.
I just realized you are located in Bavaria; depending on the exact building site there, my estimated values can vary upwards by about 5–8%.
Best regards

(Some quotes requested partly, partly searched online, partly talked to people).

Living area: 180m² (1940 sq ft)
Double garage (extended to 9m (30 feet) to gain an additional parking space).
Double garage with basement
2 full floors, plaster construction
Ventilation system – controlled residential ventilation with heat recovery

Massivhaus85 schrieb:“Fully developed” means nothing other than that the public utility lines lie in the street in front of your plot. Connections to your plot and house still need to be made.
Regarding the plot of land => it is already fully developed and located in a new residential area.
Massivhaus85 schrieb:Your supplier will hardly build your basement as a “white tank” without good reason; you probably mean a standard “WU” basement. WU = waterproof/concrete structure.
I will build the basement as a “white tank” anyway. (There is no extra charge from the builder; they do every basement like that.)

Massivhaus8526 Nov 2012 20:54Of course, every construction project is different; these are just guidelines and whether the estimate is completely off or not.
No one can plan down to the last cent anyway...
How do you arrive at the €356,500 (approximately $365,000)?
Floor coverings, landscaping, and painting are already included in my calculation.
For the plot, the following additional costs apply (according to the local authority, E.ON, neighbors):
- flat-rate electricity relocation ~ €420 (about $430)
- about €23 (roughly $24) per meter on the plot (digging yourself ~ €12 / $12)
- sewer connection on the plot ~ €1,000 (about $1,020)
