Cost of enclosed space. First draft discussed with architects

We are building in Rhein-Main. We had our provider remove the objects, we will get them separately.

Inside we have: Air-to-water heat pump, controlled residential ventilation, residential basement in WU, many windows, oak staircase, burglary protection on windows and doors, chimney, colored windows

We are building in Rhein-Main. We had our provider remove the objects, we procure them separately.

Inside we have:
Air-to-water heat pump, controlled residential ventilation, living basement in WU, many windows, oak staircase, burglary protection on windows and doors, chimney, colored windows

That sounds like a very "identical" equipment. The additional cost for burglary protection will probably be included somewhere for us.

At 2.385m basement height, is that already a living basement? – rather not, right? I can’t say about WU yet.

With the very close KfW 55 equipment, was KfW 55 not an option for you? If I could save 10-20k€ by not being KfW 55 stamp-certified, that would be an idea to consider.

No, KfW was never an option. You will never save back 10-20k in your lifetime.
2.385 will end up at 2.25 or less.

Hello everyone,

I have updated my cost calculation. In case anyone is interested. The shell construction offer is available and is within 40% of the estimated gross volume, whereby some costs (23k€) for outdoor facilities & carport foundation are already included here.

Equipment:
- 139m² living space with 67m² basement
- 2 full floors with gable roof monolithic with "Poroton"
- KFW 55
- Slope (over 22m there is about 3m gradient - is caught with 80cm (29m long) and 180cm (25m long) L-stones.
- Chimney and fireplace from Schiedel
- 180m² terrace + carport + driveway paving
- Ground floor completely tiled
- Upper floor hallway and bathroom tiled, rest laminate
- Basement will mostly be not a living basement and tiled by myself.
- Air-water heat pump + controlled residential ventilation
- 2x 3m sliding lift doors (doors + windows anthracite)
- No venetian blinds. Electric roller shutters downstairs
- Bathrooms (let's say normal) nothing concealed, showers (also in guest WC) floor-level but not tiled.
- Possibly photovoltaic system without storage but not included in the calculation.

We now end up without kitchen, furniture, move, fencing + lawn + topsoil at 523k€, of which 94k€ is land including acquisition incidental costs.

Quite a nice sum
