I have a small house (80m² (860 sq ft)) without a basement; the building structure is not particularly good. It was built in the 1950s, and there are no construction documents available. It also seems that there is no concrete slab; I cannot determine whether it has a strip foundation. The walls are thinner than standard, and due to the lack of a proper foundation and the small rooms (two floors of 40m² (430 sq ft) each), the ground floor is prone to mold and moisture.

The plot value, according to the land valuation, is €77,000. Now I am wondering whether a demolition and new build would be economically viable or if it would be better to leave it as is.

The only reason not to demolish something like this would be if rebuilding is no longer allowed, due to setback regulations, open space requirements, etc. Even during a complete renovation, it is not possible to live inside, at least not with 80m² (860 sq ft).

Please upload a site plan of the property with the house. That way, it will be easier to provide more detailed advice.

A demolition would certainly make sense. However, the building is located exactly on the boundary. Demolishing it would mean losing this development status. It would need to be clarified whether it might be possible to retain the old house and integrate it into a new construction in order to keep the status.
