Hello,
we have seen a plot of land for a house and are now considering whether we want/can afford it.
The plot is on a slope, located in North Rhine-Westphalia near the Bergisches Land. There is a preliminary building inquiry for a structure measuring 7 by 10 meters (7x10m) with 2.5 stories. The entire plot is about 400 square meters (4300 square feet) in size.
The land slopes approximately 7 to 8 meters (23 to 26 feet) over a length of around 20 meters (66 feet).
We are trying to get a rough idea of how much the house might cost...
Have I forgotten any important information?
Is it possible to make a (very) rough price estimate based on these details?
Thanks in advance,
Scrat72

hampshire19 Feb 2019 08:24Tomtom is right; stabilizing the terrain is a significant cost factor. However, it is also possible (almost) without a basement.
Haydee's estimate is roughly what our architect also gave during the first site visit. In practice, we are more than double her list—and that only includes a gravel driveway for the landscaping, which is not “finished,” but it also covers the site development and infiltration system.
I respond to suggestions to reconsider with a view. The avatar photo shows part of what can be seen from the terrace. Another snapshot is shown below.
Here are some pictures of the project on a sloping site. We have the steepest slope on the west side, facing south. The terrain also slopes towards the east, so the west part of the house is built into the hillside, while the east part stands on or above the slope.
Correct on this sketch: the slope at the house. Incorrect is that the terrain rises further to the north and that we extended the driveway shown where the carport is located. Looking at the south view: on the left and in the center is the main house (about 115 m² (1237 sq ft)); on the right are two apartments (each about 35 m² (377 sq ft)) with their own entrance for the boys (almost 18 / 20 when they move in during summer). The utility room is located centrally below the terrace and has basement-like characteristics.
Below is the west side. What is shown in red here is the boulder wall we constructed. Everything behind it under the house is not living space but rock (graywacke). The exit from the kitchen is partially obscured here—it leads to an approximately 3 m (10 feet) wide area in front of this door and provides access to the garden and the terrace that runs around the house. The house can be exited at ground level again towards the north.

@haydee: I was wondering who I can ask on site for a cost estimate (architect, builder...). If you don’t hire a general contractor but work with local tradespeople like we did, then ask the civil engineer or groundworks contractor. In the end, they were accurate and brought us the "bad" news. From that point on, the calculations were correct. The soil classifications increased the costs slightly—chiseling rock is more expensive than excavating soil. You only see what’s there once you start.
@ hampshire:
That looks really nice.
The view is always a good selling point when building on a slope.
We have a few more good reasons on our side, but if it exceeds our budget, then even good reasons won’t help much. That’s why we try to gather as much information as possible beforehand.
We also know that you can never be completely sure about additional costs.
Now I’ll start looking for a groundwork contractor.

We have a sloped site, and the view is not a factor for us since we are located down in the valley.
Our local builder was here, and he clearly dismissed the geologist’s nonsensical claims, along with my great-uncle. Then we also had a specialist excavation contractor. Both companies know every square meter of the mountain and have been working there for generations. They put the structural engineer and the architects in their place. Real calm and order came only through the company that carried out our earthworks, concrete, and masonry work.
