ᐅ Site Development Consultation for Single-Family Home Construction Projects

I have a plot of land with shrubs, large tree roots, and a slope, and I would like to discuss the costs for clearing, excavation, gravel leveling, soil and tree root removal, foundation pit backfilling, drainage, etc., with an architect before I even start the building project!

The plot is located near Freiburg and could be developed immediately, but I am hesitant because of the enormous effort involved, which I can hardly manage on my own. Can anyone advise me whether building on such a plot makes sense? I imagine that the costs up to the foundation slab installation could be quite high.

You will be helped roughly in proportion to how much information you provide about the plot. You are not allowed to link the zoning plan, but you can mention it. If the property is located in a §34 area, this changes some aspects of the construction, mainly in terms of the procedure rather than the possibilities – it simply involves a different level of assessing what is permitted.

Show the site (land registry excerpt, photos, aerial image) – important: don’t crop too tightly. Then it’s easier to say who is best to consult.

You can forget about a foundation slab on a slope; search for "11ant Kellerregel" here. Neighboring properties are a good indicator. An important point is the access and drainage from either the uphill or downhill side, as well as the severity and orientation of the slope (lengthwise / crosswise / diagonal).

No matter how dense the vegetation is, if you are already worried about these costs, it will never be enough for building the house anyway.

I especially recommend NOT asking an architect about the costs of site preparation.
Meet with a good local civil engineer or groundworks contractor on site – they will provide you with an initial estimate.

The main cost factor will probably be the fact that you own a sloped lot, and the house itself cannot be compared to a slab-on-grade house. As @Gerddieter already mentioned, I also recommend a meeting with an earthworks contractor for the clearing work. If you already have an architect, a joint meeting between all three of you would be advisable. Because the location and design of what is built is where the architect’s expertise comes into play again.
