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.

Uh, sorry to say it so bluntly:
The exterior of the house is a matter of taste, okay. It’s definitely not mine.
But the floor plan is a complete disaster – it’s a first-class amateur design. The “first-class” refers to “amateur.” You’re just trying to rationalize your room divider.
The rest doesn’t work: the kitchen is too small and almost impossible to furnish, the walk-in closet is too narrow, the hallway is too long and narrow, basically a string of rooms.
The living room is only large, but not cozy.
A basement staircase in the living area. Cheers to that.

I wonder what the purpose of having two hallways is?! When I get out of the car, I use the lower one, but when I’m without the car—even if just in the garden—I miss things up top because they’re downstairs.
Apart from that, I would skip such a staircase entirely in a bungalow. Here, you’re making it the main feature of the house. A headline could be: “Bungalow built around staircase – emergency stretcher gets stuck.”
Also, it’s still unclear where there is ground-level storage space for an office, sewing machine, etc.
If money is tight, I would actually build a bungalow without a basement. In the north, it will sink slightly into the slope, but that doesn’t matter if the utility rooms are placed there. If needed, you can use skylights, which provide nice light.
Add a double carport on the side where the main entrance and the mail carrier will be, with no barriers!
If money allows, a bungalow with two levels...
By the way, I will also correct the 2000 per square meter (2000/sqm) here, since the 2000 refers to an average, and a bungalow is proportionally more expensive than an average house. An interior garage in the house also increases basement costs, due to insulation requirements.
Furthermore, a terrace or balcony over a basement connected with living space naturally costs more than a regular terrace and a standard basement. So, I can imagine an energy disaster and thus much higher costs with this combination of basement/living space/garage/terrace.
Without rent! Where is your money going? If I were you, I would seriously think about this. We don’t even have 2900 including financing etc....
I wouldn’t include rental income at all, but treat the three-family house separately.

Thanks for the reactions and constructive feedback.
Of course, this is an amateur design...
We have gathered more ideas and input.
The basement will probably be dropped, at least with an integrated garage.
The garage will then be detached from the bungalow.
What does the group think about the attached revised bungalow floor plans?
All are between 120-125 square meters (1292-1345 square feet) of living space, each with a double garage located to the right side of the house.
The driveway will be on that side. The street runs from bottom to top on the right side.
North is at the top. The plot slopes downward from north to south.
Looking forward to your opinions.

The third option just doesn’t work at all, because with all those slanted walls it’s hard to use any room properly, not to mention the maze-like layout. To top it off, two bedrooms are positioned right next to the bathroom, so the occupants would have to listen to someone using the toilet…
The second option: where do guests shower? Having to walk through the dressing room and bedroom? That would be a deal-breaker for me.
The first option is the least problematic, but the dressing room won’t work—1.7 meters (5 ft 7 in) wide minus 60 cm (2 ft) on each side for closets equals no. However, if you straighten out the unnecessary angled walls, it has potential for expansion.
Others will probably find more issues; this is just a quick first impression…
