Floor plan of a single-family house in L-shape with approximately 155 sqm

Of course, we also hold some equity (in our daily allowance account and portfolio). But if it reaches 550k, we can still manage it. Nevertheless, with proper planning and careful price calculation, it shouldn't come to that.

The plot has already been paid for, as have the notary and property transfer tax.
Suggestions on costs we might not have considered yet would help us here?

Best regards

Sascha

I think an external construction supervisor is a must.

The calculation seems a bit too optimistic to me for Bavaria, especially currently when all prices are exploding. Earthworks and the basement were a very big chunk for us, unforeseen issues can also arise here (groundwater and white tank, earthworks more expensive than expected). I really like the living and dining rooms and also the children's rooms in your floor plan, but personally I wouldn't like the following points, maybe some of them also apply to you: - Very much space for the hallway without a nicely visible staircase being responsible for it, despite the long corridor hardly any space for furniture - Kitchen looks very small, only a short row? Is a block planned in the middle or refrigerator and storage on the sides (actually where the window is now)? - Walk-in closet separated but inside the bedroom: we also definitely wanted a walk-in closet, but placed it between bedroom and bathroom so that the person who gets up earlier then leaves the bedroom and doesn't wake the other - Bathroom on the upper floor: look at the width of the washbasin in the bathroom studio that fits here. We also decided on a T-shaped bathroom and now see during the shell construction that the access on the left and right is actually too narrow and the washbasin has to be smaller than hoped. - Living room: this might be a personal quirk but I don’t like sitting in the living room with my back to a window, I would unconsciously feel watched there and wouldn’t feel comfortable

I see somewhat over-dimensioned load-bearing walls, which - unfortunately the dimensioning is confusing - are also questionably aligned above each other. I see height specifications in the development plan that, according to my basement formula, argue against the necessity of underground storage space. I see a bathroom above the office and a "bay window," whose beam will cost more than if the house front had been "made smooth" there. And I see fantasy measurements (= "planned" botch spots). A swallow brings more summer than a CAD sketching program makes an architect.

Congratulations on the plot and the first draft. You indicate 2 people and plan with 2 children's rooms – so if everything goes as desired, it will be a family of 4?

Which optimization measures can we still consider?

They result from practical testing of the kitchen, wardrobe, and dressing room usage.
They also arise from the need for natural light. Window symmetry is not always the best solution for living. The living room would be too dark for me – but that's a matter of taste.
Not only orient yourselves on the existing furniture (realistically drawn into a well-dimensioned plan) but also have an idea of how it should develop and become. Life changes with the children and the recovering budget in the years after construction.

How could the traffic areas be further reduced?

That has already been done well. Further reduction is possible by integration into one room – for example, removing the partition wall between the kitchen and living area, instead enlarging the kitchen – of course, that comes with its own disadvantages.

Personal price limit for the house, including equipment: house with outdoor facilities max. 500k

So far, I've found figures on the internet with up to €2200 per sqm, isn't that unrealistic?

No, €2200 per sqm is no longer realistic. The outdoor facilities will probably have to wait a bit, and possibly the basement expansion as well, then it might work.

Dressing room, bedroom with corridor costs a lot of space

I thought so too. Is such a functionally restricted solution sufficient for your wife? Better to do it properly or not – that is something we should discuss together. It would also be unfortunate if the wish for a dressing room dissolves because it turns out in practice to be just an expensive walk-in closet and does not meet expectations.

The wardrobe is simply not listed separately; it would be possible in several places on the ground floor.

You will need the “several places” too – there is not much space for 4 people.

An external construction supervisor is, in my opinion, mandatory.

I don’t think so.

No, 2200€/sqm is no longer realistic. The outdoor facilities will probably have to wait a bit, and possibly also the cellar expansion, then it can work.

I thought so too. Is a solution that is functionally so limited sufficient for your wife? Better to do it right or not – we would need to talk about this together. It’s also annoying if the wish for a dressing room dissolves because it turns out, in practice, to be just an expensive walk-in closet and does not meet expectations.

You will also need "several places" – there is not much space for 4 people.

I don’t think so.

If you are a professional, then no. But those who don’t have an external building supervisor should please not complain about botched work and later damages.

Those who already "take botchers into account" during the planning should probably rather not do that either ;-)
