Hello everyone.
My wife (41) and I (47) want to build a house.
Region:
Kaiserslautern district (20km (12 miles)), Rhineland-Palatinate
House:
Solid bungalow, approx. 125sqm (1350 sq ft) with partial basement (including garage), underfloor heating, air source heat pump with controlled ventilation.
Simple design. Turnkey.
Plot:
800sqm (8600 sq ft), on a south-facing slope, road runs parallel to the slope.
Slope: approx. 19% gradient. Over 35m (115 ft), it drops 7m (23 ft) to the south.
Plot is already owned and paid for (30,000). Soil survey is available.
Infrastructure:
Gap site, supply and disposal lines run in the street next to the property boundary (approx. 2-5m (7-16 ft)).
Development plan:
Gap site, no formal development plan. Preliminary building inquiry resulted in: development according to §34.
"Development is permitted if it fits in with the type and extent of existing buildings, the construction method, and the developed area of the neighboring properties."
Finances:
Joint monthly net income: 4000.-
Children: 1, already 17 years old (no more planned).
Equity: 50,000.- available, another 100,000.- locked in until the end of 2021, building plot (see above)
We currently live rent-free in our own three-family house in the city.
Rental income: Ground floor: none (my mother lives there), 1st floor: 600.- net rent, 2nd floor: we live there ourselves (will be rented out upon moving. approx. 650.- net rent).
Joint monthly expenses (total): approx. 2900.-
So monthly savings are 1100.- plus rental income as above.
Therefore, approx. 1100.- plus rental income is available for financing.
We have made a rough cost estimate so far.
Please correct any possible miscalculations on my part!
Plot costs including incidental costs: 30,000.- (already paid)
House costs (bungalow): 125sqm (1350 sq ft) * 2000.- = 250,000.-
Partial basement with integrated double garage: 50,000.-
Additional building costs: 80,000.-
Outdoor facilities: 20,000.-
Buffer: 20,000.-
Total budget approx. 450,000.- gross
Is this realistic?
Attached you will find a cadastral map and a rough idea of the exterior view from the street.
(The current slope is shown in green.)
I am open to any suggestions. Thank you.

What? Is the basement staircase coming up or down right in the middle of the living area?I agree. The floor plan is quite unusual. That long hallway from the entrance would drive me crazy. You’re always looking straight down a narrow passage. The kitchen is also relatively small.
I’d definitely wait a bit longer before finalizing the floor plan. There are users here with really good advice that you should listen to. You can definitely get a lot more out of the house without causing a major cost explosion.
Financially, it should be manageable. Your expenses will likely decrease in the coming years once your child moves out… although it’s probably better not to say that too loud.
A partial basement does not save as much cost as is often assumed. Additionally, problems are more likely to occur with a partial basement if there are any ground settlements.
Depending on the soil, settlements in buildings are not uncommon. If the load can be evenly distributed, this is not an issue. With a partial basement, however, the effort required is greater.

Huh? Does the basement staircase actually come up in the middle of the living area?Yes. That was actually the plan. I know it’s not everyone’s preference.
But it’s also meant to function as a room divider. It’s easier to see that in the picture without exterior walls.
Are you really a "new user"? – this project seems familiar to me.
