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,

Bathroom is the room with 11.725 sqm (126 sq ft), with a bathtub (wife’s preference).
9.218 sqm (99 sq ft) is the walk-in closet.

I must have taken a wrong turn...
Can I move this?

How should I understand that? Several items are at least included in the rough construction offer, specifically: green flat roof, wood facade, and brickwork according to the offer are included.

Many thanks in advance for the past and future replies...

The additional construction costs are missing, everything marked as “builder’s scope” and anything not listed.

I would eliminate a few corners.
Why is the upper floor positioned so centrally and not aligned with the exterior walls (structural engineering)?
Is there already a calculation from the structural engineer?
If not, the budget will likely be insufficient.

The hallway is too large, the bathroom is a wet room, and there is no space for a freezer in the pantry.

Include all desired and existing furniture to scale in the floor plan.
