Hello everyone,

We are still planning to build this year.
It will be an urban villa, or due to the single-story restriction (2/3 rule), with extensions on two sides. KfW 70 standard.
The rest is based on the floor plan.
We generally like the layout, but we might have overlooked something, so we would appreciate any feedback on our floor plan.

Floor area ratio: 0.4
Number of parking spaces: 1
Number of floors: 1
Roof type: hipped roof

Owners’ requirements:
Basement: no
Number of people, ages: 3, ages 1–30
Office: family use
Overnight guests per year: 0
Open kitchen with island
Garage

House design
Planner: architect
What we particularly like: basically everything

Thank you in advance.

You cannot compare Hamburg to a small town.

And anyway, why so aggressive? Can you not accept that someone can build more cheaply than you?

I live in a village, I'm not aggressive, and I honestly don’t mind if someone builds more cheaply than I did (by the way, I built several years ago). I’m just trying, like many others, to help people who are similarly naive avoid future disappointments. Apparently, this is not always welcome. A price of 1,300 €/m² (about $140 per sq ft) is simply completely unrealistic. At that rate, they even have a good chance of getting their half-finished house featured on television.

Our first on-site consultation with a building company resulted in €1300 per square meter (approximately $130 per square foot).

You haven’t built yet, @alexm86, and apparently you haven’t signed a contract either.
Therefore, I tend to agree with the skeptics here, since your house is very large (how many square meters?), complex, and includes some costly details (according to the documents you posted here).

Be glad someone is advising you to double-check or question the house price rather than accusing your advisors here of being aggressive.

Best regards, Yvonne

By the way, how many square meters was it again?

1,300 sq meters (14,000 sq ft) is difficult in Lower Saxony, but not completely unrealistic. It depends on the level of finish. We have a fixed price of €280,000 for our city villa (construction starting soon). It’s 188 sq meters (2,023 sq ft), almost the same size. That corresponds to €1,487 per sq meter.

However, we have a lot of things included: underfloor heating, geothermal heat pump, ventilation system with heat recovery, soundproof bricks for the interior walls, concrete staircase, RC2 rated windows and doors, large garage 6 x 9 m (20 x 30 ft) including sectional door.

If you remove all of that, the cost would have been around €230,000. Then add the garage for €10,000 - €15,000 more, and that roughly matches the 1,300 sq meters.

But: the electrical and sanitary fittings are minimal. We are still budgeting an additional €10,000 for that.

So I don’t think that’s completely unrealistic.

That doesn't seem completely unreasonable to me.

Thanks, at least one agrees.
Two major items we won't have are the ventilation system and the geothermal heat pump including drilling, which cost about 20,000-25,000 EUR, so then we're at 260,000 EUR, which equals approximately 1,390 EUR/sqm (square meter), and we've included a bit of a buffer in our financing.

What about flooring and painting? By the way, your gas heating system also incurs costs...
A difference of 90€ per square meter also means additional costs of 9,000€ for 100 square meters.
