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,

My warning that this might not be allowed to be built in this way is no longer relevant – but my point remains: if you take an energy-efficient house seriously even to some extent, such an unfavorable building envelope-to-volume ratio works strongly against it. I was not aware of the efficiency aspect, and apparently neither was the contractor. Although he suggested a 40+ house, he never mentioned any potential inefficiency in the planned design. Nor did he say anything about the building envelope-to-volume ratio.

(and not to put the upper floor on in the proportions of a shipping container) Personally, I like it... even very much. Especially with the wooden facade.

Did I actually overlook it, or has there been no response yet to my surprise regarding the combination of "timber frame" and on the other hand solid construction “wall” opening dimensions? I didn’t overlook it. I would like to respond but, unfortunately, I don’t fully understand the question.

Young children especially want to take baths when there is a bathtub in the house. But is it really planned for the little ones to have to go up and down stairs all the time? Oh, I forgot, “back then” They should have healthy legs, after all...

I agree: there is more to be done in terms of functionality, practicality, aesthetics, and energy efficiency. If this keeps up, my next topic will be “looking for an architect.”

Sorry, have we already seen the site plan with the surroundings and dimensions??? Yes. Now...

Yes. Now... Correction... meanwhile, the layout is a little different:
26 meters (85 feet) wide, 50 meters (164 feet) deep

I would like to respond, but unfortunately I do not fully understand the question. Well, what confuses me is this: You mention timber frame construction, yet the door and window dimensions shown in the drawing are typical for masonry houses (octameter plus joint). That makes sense for masonry buildings, but for timber frame houses it's firstly unnecessary and secondly they use different construction grids. So I am uncertain what exactly you are building with.

I wasn’t aware of the efficiency aspect. You should be, if that is your goal, and not just a marketing line from the builder like “we’re already building to the 2030 standard for you.”

And apparently the builder wasn’t either. He did suggest a 40+ house, but never mentioned any possible inefficiency with the planned project. Let alone anything about the envelope-to-volume ratio. Sure. He doesn’t earn more money if you reach the “better” energy standard smartly, but if you do it through added technology and more materials. So it’s not in his interest to advise you purposefully, but rather to maximize profit. Still, even with today’s Pisa education system, one should at least have a basic understanding of concepts like hibernating hedgehogs. Even I know that, despite having missed physics classes forty years ago due to teacher shortages.

Yes. Now... Uh, no. A captionless image still doesn’t say more than a thousand words.

Correction... the layout is now a bit different:
26 cm (10 inches) wide, 50 cm (20 inches) deep Doesn't matter. Many other things would be interesting.
