ᐅ Your opinions on our floor plan and quote

Hello, my wife and I plan to build next year and have found a suitable plot (704 sqm (7,570 sq ft), 18.5 m (61 ft) wide, facing south) where we are only allowed to build a single-story house.

Our house concept is a gable roof with the highest possible knee wall (about 150 cm (59 inches), 25-degree slope) and a transverse gable facing south and the garden.

We have now found a provider who made us the following offer with the following floor plan and specifications:

- Single-family house with approx. 170 sqm (1,830 sq ft) of living space
- Upper floor with floor-to-ceiling windows
- Utility room with entrance door
- Double doors to the living room
- Roof overhang at the eaves approx. 80 cm (31 inches) and at the gable approx. 30 cm (12 inches)
- Insulation according to KfW 70 standard (two-layer, 45 cm (18 inches) wall thickness with brick facade)
- Windows with triple glazing, colored on the outside, u-value = 0.7 W/m²K
- Electric roller shutters in the bedrooms
- Guest toilet with shower
- Roof covering with engobed clay tiles Nelskamp F 7
- Patio doors with new-build threshold
- Underfloor heating on ground and upper floors
- Ventilation system with heat recovery and central heat exchanger Vallox type controlled residential ventilation - SC with integrated summer bypass in the utility room, 4-stage controller Vallox VSS, duct system for supply and exhaust air
- Velux (roof windows)

Otherwise, tiles in the usual rooms; painting and other flooring work are additional. The total cost for the house is 195,000 euros!

I have the following questions:

Can you comment on the price? Does anything stand out? (I know this is not a complete list.)

Do I need a solar system for domestic hot water (which is included in the purchase price), or can I remove it and still meet the KfW 70 standard?

Here are the floor plans:

I look forward to your comments ...

Attached are the pictures

What additional costs are you budgeting for? I’m thinking of site preparation, foundation slab, utility connections, and similar expenses. I estimate another 40,000–60,000 EUR (45,000–67,000 USD) for these. The purchase price and related fees for the land are probably already clear.

And are you sure that with the floor plan on the upper floor you will maintain the single-story design?

I am neither an architect nor familiar with the building regulations in Lower Saxony, but I find this somewhat questionable.

I think it’s a pity that the dressing room is the nicest space ... 🙁

Otherwise, I find the floor plan quite nice (although I don’t understand why you need a dining area in the kitchen when the dining room is just 2 m (6.5 ft) away).

Is the bathroom layout going to stay like this?

Regarding the price: Something seems off if you’re paying under €200,000 for a 170 sqm (1,830 sq ft) house with brick cladding. There must be additional costs, right?

Site work is sufficiently covered in the construction description; it’s a new development area, and the soil report confirms this. Utility connections are around 5,000 euros (about 5,400 USD). For other additional costs like building permits, the soil report, and temporary construction electricity, I budgeted another 5,000 euros (about 5,400 USD). Architect fees and similar costs are already included.
