Hello everyone,
Two months ago, we purchased a serviced building plot on a hillside and are currently deeply involved in the floor plan design, which is proving quite challenging due to the elevation difference.
I have been following the forum for a while and recently found a great template for our project that I think just needs some adjustments to fit our requirements. I would really appreciate your feedback and am, of course, open to criticism!
Development Plan / Restrictions
Owner’s Requirements
House Design
If you have to give up something, which details or features
Why does the design look the way it does?
We really like the design here by "kaho674." It truly reflects our ideas. The upper floor should still fit now but, of course, with our minimum required room sizes and the requirement to build only 1.5 storeys.
What is really important to us, especially since the plot is on a slope — the highest point at the street is just under 1m (3.3 ft) above the zero level and it drops 5.11m (16.8 ft) to the lowest point — is how everything can be integrated into the plot without the costs for filling and leveling running out of control. We have also considered an alternative to the urban villa in the style of a split-level house. What have your experiences been building on such a plot?
Many thanks

I already told you what you need to include and what you can exclude in your calculations. My estimate also includes two levels of 65m (213 feet) L-shaped retaining walls, each 80–100cm (31–39 inches) high, along with terrain modeling. This will cost me around €30,000 gross. Could you please repeat that including the terrain modeling? There’s so much information here that I’ve lost track of what is necessary and what isn’t. Thanks!
You can expect to pay around 2000 per square meter (approximately 186 per square foot) just for the house.
As someone from Lower Saxony/Northern Germany, your costs might be somewhat lower... however, these prices have been quoted for about a year now, and costs are continuously rising.
I would definitely include this estimate in your planning.
In addition, there are 25,000 in additional construction-related costs, and in your case, I would add another 30,000 due to the slope.
Paving will cost another 10,000, the carport 5,000, and painting/flooring around 10,000.
Of course, everything could be done more cheaply, but I would base calculations on average values.
You really need to get involved yourself to develop a feel for it.
Going through your own thread is the least of your problems, I would say.
You should create your own numbers because otherwise, costs tend to get underestimated.

Kannst du mir das noch mal nennen incl. Geländemodellierung? Hier steht so viel drin das ich die Übersicht verloren habe was nötig ist und was nicht. Danke!

If I exclude my basement now, you should expect somewhere around €380,000 for 139 m² (1,495 ft²) including a double carport, terrain modeling, and additional construction costs. Possibly plus €10,000 for a thicker foundation slab due to the slope. This does not include the kitchen. But €380,000 is a good reference point for you.

Ok, I had roughly estimated €350,000, but thanks for that!

I would at least plan for that.
Additionally, expect around 25,000 for incidental building costs. In your case, I would add another 30,000 because of the slope.
Paving would be another 10,000, carport 5,000, painting/flooring 10,000.
Of course, you can go the budget route, but I would calculate with average values.

And browsing through your own thread is the least of your worries, I would say.
You should form your own numbers; otherwise, people tend to underestimate the costs. The living area is supposed to be about 140 sqm (1,507 sq ft), maybe "a bit" less. I initially just wanted a rough estimate, since you also mentioned here that in the end the prices depend on personal preferences—for example, wood staircase or glass staircase!
But now we probably need a rough floor plan first, right?
