ᐅ Estimated Construction Costs for a Single-Family Home in the Tübingen Area

Hello everyone,

I’ll briefly describe our situation. We have reserved a plot of land for a single-family house. We would like to build a solid (whether Liapor or another type of "masonry," we are not really sure) structure on it. The plot is flat and square, measuring 417 m² (4490 sq ft).

We are allowed to build 2 full stories with SD, PD, FD, although only one SD is an option (maximum ridge height 9.5 m (31 ft), maximum wall height 6.10 m (20 ft)).

So far, we have received offers ranging from €3500/m² (local large contractor) to €2800/m² from, for example, Fingerhaus (probably excluded due to timber frame).

Now to our dream house:
- KfW 55 standard
- solid construction method (type not clear, will depend on budget; do Liapor and “masonry stone-on-stone” not differ much in cost?)
- 140 m² (1507 sq ft) living area
- 1.5 stories with a “high” knee wall
- basement (utility cellar, which can be finished later, connections for heating and electricity installed)
- house dimensions (determined by room requirements? 11 x 9 m (36 x 30 ft)? 11 x 10 m (36 x 33 ft)? Building area ratio of 0.4 is sufficient)
- including photovoltaic system with battery storage
- turnkey delivery

- Basement: technical room + laundry (15 m² (161 sq ft)) + large hobby room (approx. 30 m² (323 sq ft)) + fitness room (15 m² (161 sq ft)) + cellar (10 m² (108 sq ft)?) + hallway / stairs (? m²) = 70 m² (753 sq ft) + x
- Ground floor: living & dining area + kitchen (approx. 45 m² (484 sq ft)) + pantry (3 m² (32 sq ft)?) + guest room (>12 m² (129 sq ft)) + shower bathroom (4 m² (43 sq ft)?) + hallway / stairs (? m²) = 64 m² (689 sq ft) + x
- Upper floor: child 1 (16 m² (172 sq ft)) + child 2 (16 m² (172 sq ft)) + master bedroom + dressing room (20 m² (215 sq ft)) + bathroom (14 m² (151 sq ft)) + hallway + stairs (? m²) = 66 m² (710 sq ft) + x

Calculating room and floor area requirements (without the unknown x for stairs and hallways/entrance) we come to approximately 130 m² (1399 sq ft).

Our specific questions are,

a) Which “solid construction” companies do you generally recommend in the Tübingen area?
b) How much area should roughly be allowed for hallways and entrance / stairs? Yes, it depends on the floor plan, but we would like to estimate the total space requirements.
c) What rough price range should we expect in €/m² (living area) + €/m² (basement) for Liapor or other masonry? We do not want to consider additional costs like kitchen and garage here, but they are naturally included in the overall budget.

We hope you can help us. Please feel free to ask questions—I’ll respond promptly.

Have a nice evening!
