Hello everyone,

we are planning to build a single-family house in Lower Saxony and have requested a quote based on the floor plan (see below).
We initially aimed for about 150 to a maximum of 160 square meters (1615 to 1722 square feet), since it’s just the two of us. We have now ended up at around 170 square meters (1830 square feet). I would have been fine with an office of 10 square meters (108 square feet). The hallway, however, is quite large at 21 square meters (226 square feet). The other room sizes feel comfortable and reasonable. We don’t really see where we could reduce size without making the house look unbalanced. (Opinions on this are welcome.)

About us:
- Both employed (permanent contracts)
- Net household income 5,000
- Equity 45,000
- No children

(All costs currently considered without additional running costs)
- Land cost: 71,000 for about 1,300 square meters (0.32 acres)

Offer for the single-family house in timber frame construction as an Efficiency House 40+ as follows:
Turnkey: approx. 448,000

Closed shell: 260,000
Shell including:
- Building permit application, drawings
- Earthworks
- Concrete works
- Walls
- Lower facade with clinker bricks (mandatory according to development plan/planning permission)
- Upper facade with wood
- Roof structure
- Flat roof
- Green roof on ground floor and upper floor (mandatory according to development plan/planning permission)
- Windows, white PVC, triple glazed
- Staircase

I find the difference of roughly 200,000 euros (approx. $216,000) very large – maybe I’m just thinking too much like a layperson. (Opinions here are welcome.)
Therefore, we are currently getting quotes for the following trades:
- Heating, sanitation, ventilation installation
- Tiling
- Painting
- Joinery for floors and doors – possibly doing the flooring ourselves
- Screed laying
- Electrical work

Decisions already made for us:
- Heating: air-to-water heat pump
- Photovoltaic system
- Flooring: 1. Tiles in the guest bathroom downstairs, bathroom upstairs, kitchen, and utility room – for bathroom fixtures and tiles, we plan to go with “standard,” nothing extravagant.
2. Vinyl flooring in the rest of the house
Possibly laminate flooring in “Children’s rooms 1 and 2” – currently no children, planned earliest in 5 years

Undecided:
- Efficiency House 40+ or 55

Looking forward to your opinions.

Best regards,

This is the exact wording:

For the main roof surfaces, gable roofs and half-hipped roofs are permitted – garages and ancillary structures and green roofs are excluded from this.

What I would change: remove the pantry and enlarge the kitchen, expand the guest WC into a real children’s bathroom. If the two children’s rooms are actually going to be used, they are simply too small!

Pantry… tricky topic – it’s my wife’s wish. But I’ll try to gently bring up the idea… wish me luck.

But: please definitely reorganize the layout! The narrow corridor will never be a walk-in closet but will always remain a narrow corridor. With this amount of space, there should be a better solution. Do you really need a 12m² (130 sq ft) bathroom for two? Probably not. You could easily take some space and add it to the closet, but overall the layout needs to be different…

For me, a 10m² (108 sq ft) bathroom would also be sufficient. Personally, I could easily do without a bathtub… but then we are back to the topic of my wife and possibly children in the future.

Last but unfortunately not least: the budget won’t be enough. At least with this specification and building type, I don’t see 450k all in. Do you have a buffer or are you able to contribute some DIY work? Then it might (wasn’t this Lower Saxony, where it is a bit cheaper in rural areas?!) be feasible.

Currently, I save at least 1.3k every month. So, even if it’s a small buffer, it is increasing. With a net income of 3.2k and fixed costs including rent, electricity, insurance, etc. of about 1.1k, this is very doable. And I still allow myself the sugar-free diet soda…
As for DIY, we currently can only contribute when it comes to flooring and doors. So cost reduction will probably be limited?!
Edit: Yes, Lower Saxony.

Do you know: I’m confused about the hyphen (or whatever it’s called).
Is this really used in a development plan?
Would you be willing to post the complete development plan or at least provide the name of the district including the building area?

Does it really exist in a development plan / zoning plan?
Could you please share the entire development plan or at least name the county including the building area?
... the dash does exist, at least in this development plan / zoning plan.
But it’s good that you mentioned it again. I was a bit inattentive myself and definitely should have included the first and third paragraphs — or just the picture right away.
But have a look for yourself:


Excerpt from a legal text about roof pitch, roof types, and green roofing.


Edit: I apologize for my oversight and for providing incomplete information...

Yes, I interpret it the same way as you do.

I agree with @11ant.


It is correct and important that you point this out. For my statement, I used the passage from the questionnaire as a direct quote and therefore as the basis. The excerpt that came most recently confirms this in my opinion: they almost seem to prefer green roofs, given how often this is specifically highlighted as an exception.

We initially planned one as well. But it didn’t really require luck, just good arguments. In relatively small apartment kitchens, it certainly makes sense, but if you can plan the kitchen from scratch, (we) don’t really need it anymore. Our pull-out cabinet is brilliant and exactly designed for the “pantry items,” which is sufficient.

Then the layout downstairs is not consistent, as I said. If children are expected, then there should be a larger bathroom downstairs. The bathtub can still be upstairs with you; it fits well in 10sqm (108 sq ft).

That’s very good and by the start of construction would already mean about a minimum of 15k more, with an upward trend. This is essential because:

Right now, we will only contribute labor for the flooring and doors (can do that). So cost reduction is rather limited?


Yes, more than limited. Flooring is usually not included in most “turnkey” offers anyway, but always considered as self-performed work or to be contracted separately. What does the contract say again about this? Same applies to painting work, by the way.
