Cost approach construction contract / Overpriced?

Hello,

we are considering building a house and have already had the plot planned by a kind of property developer. As part of the planning meeting, the costs for the house as well as ancillary construction costs in a broader sense were calculated. A "decent" sum came out of this, so we are wondering whether we might have come across an expensive company or whether building has simply become very, very expensive by now.

I will just list the items here and look forward to feedback or assessments.

House connections including earthworks (water, electricity, gas, wastewater, collective media introduction) - total cost €16,500

Ancillary construction costs for the basement (earthworks basement excavation, disposal of excavated soil) €30,000

Fully finished basement, sealed according to the soil report, without white tank, one light well, external staircase - cost €100,000

Ancillary construction costs (construction water and electricity) - total cost €2,500

Costs for painting and wallpapering work, floor coverings including labor - cost €30,000

Cost of finished garage with storage room €13,500

Calculation house 210 sqm x €2,100 per sqm - €441,000

In addition, there is the plot itself, which can be left aside here.

Are these prices realistic or overpriced? We live near a big city - of course that also has an impact on the craftsman prices.

Many kind regards to everyone here...

You have been silent about the building itself In that respect, it is even harder to assess than usual. But I don't find the approach entirely wrong. Basement apartment with excavation ... you are building 300sqm of living space, which is usually enough for two families. Are you aware of that?

What price were you roughly expecting?

Which region?

To be honest, I can't really provide many details yet.

We don't have the construction performance description yet. Electric shutters, barrier-free sanitary facilities are included. So not standard, but also not luxury.

We want to build in an area adjacent to Cologne.

The house will be a single-family house, purely living space. Approximately 210 sqm. So no multi-family house. The basement is not planned entirely as a "living basement," but has exactly 1 light well. That means one additional room with daylight. The other rooms are only intended to have normal shafts.

The reason I can't say much about the construction performance is that so far I've only had the standard version without any adjustments in front of me, and I will probably only find out the details or exact pricing once this planning contract is signed, because the developer only puts out the tender and prices exactly afterwards. Now the company wants to conclude a planning contract with us in advance. However, in my opinion, then we are completely at their mercy, or am I wrong!? Then a lot can be included or excluded in the construction contract, or it can become expensive, because we are basically bound by the planning contract, or can cancel it but still have to pay the fee. In the planning contract, it states that costs incurred under the planning contract will only be credited if the construction contract is concluded.

Is this the "normal" procedure?

I think not at all - without knowing the prices in Cologne - in the end there will still be a big five at the beginning, I would increase by 100: kitchen by 20, sanitary reinforcement + 15, floor work 20, electrical 5-10, lamps 5, and so on... In the end, the offers are usually twice as expensive as you naively estimate at the beginning. And then there are garage, driveway, platform, soil, fence... can easily cost another 50, rather 100...

*Clears throat*
210 sqm plus living basement (either no room or all) comes at a price.
I’d say: with us, 4-person families buy 109 sqm without a basement. Ok, I don’t need that either. But written in bold 210 plus basement... that’s quite a figure, you really have to think that through. The salary should definitely start with a 6 or 7.
You should weigh whether you really need that much living space – just write a room program, and then calculate it for yourself. Often, you can give a room several functions like office and guest room, sports and play, pantry and technical room.

By the way: he also has no influence on half of the prices mentioned by the GU (?), e.g. connection costs, electricity/water... those are ancillary construction costs from which he gains nothing. And the higher he estimates, the better it is for you.

In addition, there are the exterior facilities such as the entrance platform, paving work for the terrace and driveway, and garden design.

And no, it is not true that the true prices for extra equipment are not mentioned. They must be provided by the GU in writing, if you request them.

Only when all costs have been communicated by the GU does one sign the contract. It must be mentioned that some costs are only roughly estimated, such as the earthworks. These are determined based on the soil investigations.
