Enlarge and fully renovate a single-family house or demolish and rebuild?

You can't just widen a house by 3 meters. The old walls have to remain. At most, an extension is possible. We pictured it something like this: Does it work?

Hello everyone, Here is the situation: We can get a plot (600sqm) with a house from the 60s with 105sqm living space on 2 floors for €150,000. The land value (standard land value) alone is €130,000. However, the house is too small for us. We would like to carry out the following measures (the development plan allows everything): 1. Enlarge the house by 3 meters to the back and 3 meters to the side. 2. Increase the number of floors 3. New roof 4. New exterior facade 5. Complete interior renovation. In other words: We basically want to redo everything. Can it be worth it or does demolition and new construction make more sense? Are there tips for funding (KFW) etc.? Sorry, but I am (still) an absolute beginner. I know you can't predict costs here. But maybe there are people who have undertaken a similar project ;) I am grateful for any information.

Short answer: no. But we can gladly tell you what is possible - your homework on this is in post #4.

Can you also tell me why that doesn’t work? As I said, complete novice!

That works if you like an L-shaped room that is 2m wide on one side and 3m wide on the other side. But 99.99% of home builders can’t do anything with that. Neither can I.

If you seriously want to know what is possible, you need a structural engineer and an architect. For initial ideas of what might work, we need the current floor plans and an overview of the neighboring plots (keyword building boundaries).

To assess whether this makes sense compared to demolition, again the current floor plan would be necessary and your requirements profile for rooms and use.

Without that info from you, we CAN only answer here as does.

1. Enlarge the house by 3 meters to the back and 3 meters to the side. 2. Increase the number of floors 3. New roof 4. New exterior facade 5. Core renovation inside. In other words: We basically want to redo everything.

Counter question: what exactly of the old house will still remain afterwards? If for your homework

Name the exact year of construction, show photos, current and planned floor plans, and also a cross-section.

no answers can be found in grandpa's folders, you can also inspect the building file at the building authority and have copies made from it. THEN we can tell you what’s possible.

Does it work?

No, because of the structural engineering. The floor slabs rest on the exterior walls, so you can't just remove them. The exterior walls generally have to stay. Door openings would still be possible so that you can get into the extension with the 2m hose room. With a lot of money, of course, it could be done, if you had a listed facade or something like that, but tearing down and rebuilding is the way you want to go and also the cheapest way for what you have planned. Have you already bought the property or is it the inherited one from your other thread? If plots are not yet scarce in your region, it might be cheaper to switch to a vacant plot without any existing buildings. You would have to get quotes for the demolition and compare with other plots.
