House construction is about to begin!!! TIPS TIPS TIPS

Hello everyone,

I and my surroundings are absolute novices when it comes to construction.
I have now purchased a small 219 m2 plot and will build a semi-detached house on it.

The semi-detached house will have 2.5 floors. I am attaching a picture of what it should look like and some plans.

I WOULD BE REALLY INCREDIBLY THANKFUL FOR ANY TIP.

Current status:

I have an offer from an architect who acts as a general contractor.
For the house without a basement with 154 m2 there is a fixed price of 295 thousand euros.
Not included in this:

Painter and flooring work

Extras included:

Underfloor heating on the ground floor and first floor
Triple-glazed windows
Sanitary installations for guest WC and main bathroom
Paving of the terrace
Building application / building permit
Construction site expenses
Soil survey
Land registry office measurement

What should my next steps be?

Is this price-performance ratio sustainable? Is 295 thousand for solid brick construction a lot?
Where is there potential for savings for a construction layman?
Should I commission some construction work to other craftsmen myself?
How and where can I get comparison offers?
Where can I find other construction companies or general contractors to compare? I am building in Krefeld.

The land seller told me that although you cannot negotiate the price with him, you could get gifts.
What would be realistic?

And I would be incredibly grateful for any other tip.
What else should I think about now...

How's it looking with finances?? I'm a pro at nagging!

The architect's price estimate initially appears realistic. Read up a bit and and especially compare the additional costs with your plans and the construction service description of the general contractor. I find the house plan initially workable; a bit more information about the plot would be interesting. Why not add a small bathroom in the attic? P.S. I just made the connection to your other post again, which also includes a site plan. Are you the northern or the southern plot?

I find the house plan practical for now; a bit more information about the plot would be interesting.

So the plot is southern. The garden would face southwest.
In the first conversation, the architect spoke of a fixed price including additional construction costs.
295 thousand euros fixed price.
Except for floors and wall coverings as well as garden design and 4,000 euros for “connections.”
Otherwise, everything “else” is included in the 295 thousand euros. (see above)
A bathroom in the attic would be subject to an extra charge, but I will ask the general contractor for goodwill.

What do you mean by that?

He means whether you make a living from collecting empty bottles or if something else is making the numbers in your account grow...
