ᐅ Planned New Single-Family House Construction – Floor Plan Available

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,

"elongated rectangular prism loses more heat than a compact rectangular prism"In that case, the best option would be to build a spherical house, as it has the optimal ratio of volume to surface area. If you insist on right angles, then a cube is indeed the closest shape.This house is an extreme design choice, and as is often said, taste cannot be disputed. Honestly, it would definitely not be my preference. That jagged shape, the flat roof with the captain’s bridge on top... but the original poster has to like it. The critique points—small children’s bedrooms and tiny bathroom on the ground floor, poorly zoned master area—have already been mentioned.
I suspect that if the budget is exceeded, we are not just talking about minor overruns; the main cost drivers have already been outlined. I find it hard to imagine building this complicated form, including the green flat roof, for anywhere near €450,000 (approximately $485,000). Even a €15,000 (about $16,000) contingency is practically nothing here. Also mentioned in passing was the aim to manage the project with €3,200 (about $3,450) net income. This project will therefore require a very high level of personal equity investment.

They want to manage the whole thing for 3,200 euros net.Is that right?

If this keeps up, my next topic will be "looking for an architect."
Yes. Now...As @11ant already mentioned, the site plan is nice and all, but it’s pointless without a legend. What I can make out are contour lines. And quite a few, too. You said there is no slope. With a 5 m (16 ft) difference across the property, I would definitely call that a slope. If that’s correct, the design wouldn’t be feasible anyway.

I wouldn’t consider this extreme desirable in reality – but it’s also not exactly the opposite, as planned here. And if you want to not only meet basic standards but even achieve KfW40+ certification, the builder might as well order his next Porsche twice over.

What I do see are contour lines. And quite a few of them? You wrote that there is no slope. With a 5 m (16 ft) difference across the plot, I would tend to call that a slope. There are four dashed lines between two solid contour lines – so probably 20 cm (8 inches) each – and together, the five lines represent one meter (3.3 ft). But in the end, it’s just a sketch that only someone who knows what it’s supposed to mean can really "read."

But it remains an image that only someone who understands what it means can “read.” Okay. I just thought the 56 and 52 were height measurements above sea level. For Lower Saxony, that would be within the realm of possibility?

Currently, I save at least 1.3k every month. This way, my buffer continues to grow, even if only slightly. With a net income of 3.2 and fixed expenses including rent, electricity, insurance, etc., of about 1.1, this is very achievable.For @ypgSimilar topics
