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,

Floor plan as follows:
I don't have anything against the fragmented building form, but what I would do is leave the parent area completely open upstairs, with no walls except maybe for the bathroom and possibly around the staircase (but made of glass there). Quite impractical for everyday life, but it always looks so great in architecture magazines...

I don’t mind the fragmented shape either, but what I would do: keep the parents' area upstairs completely open, no walls except maybe for the restroom and possibly to the staircase (but made of glass there). Quite impractical for everyday life, but it always looks so great in architecture magazines...First of all, I want to express my enthusiasm. I really appreciate that you don’t just think about it but you, Tamstar, even invest time in the drawing.Regarding your drawing: It will definitely look great, or rather, it certainly does in all those magazines. Personally, I also like it a lot in the various hotels where I stay for work during the year.
“Impractical for everyday life” is a good way to put it. I want to have my peace when my partner gets up earlier in the morning — or vice versa. Therefore, we don’t want the bathroom directly adjacent to the bedroom, let alone a completely open area.
In our current apartment, the bathroom is directly next to the bedroom. You hear everything, starting from the shower and hairdryer up to the exhaust fan in the bathroom.
With the clarification from the excerpt of the development plan, we now know what is allowed: the original poster has the freedom to design a flat roof on the condition that it is greened. This seems to reflect the typical composition of the local council: apparently, there is a significant eco-friendly faction that insists on green roofs—but at the same time, no shed or tent roofs are desired. So, no Pinterest-style new development; vegans if necessary, but no Gucci dog leashes.
My warning that this might not be allowed to be built is therefore no longer relevant—but my point remains: if you take the concept of an energy-efficient house even remotely seriously, such an unfavorable envelope-to-volume ratio pushes things too far in the opposite direction. The floor area ratio of the ground floor to the upper floor, roughly 4:1, I would at worst moderate to 2.5:1 (and the upper floor should not be stacked with the proportions of a shipping container). An Oval Office-style layout could actually be quite stylish—even without a bathtub in the bedroom. Did I miss it, or has there not yet been a comment regarding my surprise about the combination of “timber frame” and “solid masonry” wall opening dimensions?

Quite unrealistic for everyday life, but in architecture magazines it always looks great...

It is correct and important that you point this out. For my statement, I took the passage from the questionnaire as a direct quote and thus as a basis. The excerpt that came up most recently confirms this in my opinion: they almost seem to prefer green roofs, given how often this is specifically emphasized as an exception. Sorry again, I wasn’t paying close enough attention here.

But as I said, it’s not consistent below. If there are children, then a larger bathroom downstairs; the bathtub can still be upstairs with you, it fits well in 10m² (107.6 sq ft). I will take another look at the “children’s bathroom” at my parents-in-law’s place and measure it. For me, it has an ideal size.

Yep, more than manageable. Flooring is usually not included in most “turnkey” offers anyway, but always by extra charge or arranged by yourself. What does the offer say about this again? Same goes for painting work, by the way. According to the “turnkey” offer:
Floor coverings
1. Supply and professionally apply leveling compound including primer on the screed
2. Supply and install 1.8mm (0.07 inches) impact sound insulation underlay from “manufacturer”
3. Supply and install “manufacturer” vinyl “dimensions” including skirting boards

Then it’s not consistent downstairs as I said. If there are children, then a larger bathroom should be downstairs, but the bathtub can still be upstairs with you; it fits well in 10cm (5 inches)². I don’t think that idea is fully developed yet. Especially children want to bathe if there is a bathtub in the house. But is it really intended that the little ones have to go up and down the stairs all the time? Oh, I forgot “back then”

If you seriously want an energy-efficient house, such an unfavorable building envelope to volume ratio swings too much in the wrong direction. Even the floor area ratio ground floor to upper floor of about 4:1 should be reduced at worst to 2.5:1. I agree: there is room for improvement in terms of functionality, practicality, aesthetics, and energy efficiency.
Sorry, have we actually already seen the site plan with surroundings and dimensions???
