ᐅ Enlarge and completely renovate a single-family home, or demolish and rebuild?

Hello everyone,
Here is the situation:
We have the opportunity to buy a plot of land (600 sqm (approximately 6458 sqft)) with a house from the 1960s that offers 105 sqm (approximately 1130 sqft) of living space over two floors for 150,000 €. The value of the land alone (land reference value) is 130,000 €.
For us, however, the house is too small. We would like to undertake the following measures (the development plan allows all of these):
1. Extend the house by 3 meters (about 10 feet) to the rear and 3 meters (about 10 feet) to the side.
2. Add extra floors.
3. Install a new roof.
4. Replace the exterior facade.
5. Complete interior refurbishment.
In other words: we basically want to redo everything.
Would this be financially worthwhile, or would demolition and rebuilding make more sense? Are there any tips regarding funding options (KfW programs) or similar?
Please excuse me, as I am (still) a complete beginner. I understand that it is impossible to predict costs here, but maybe there are people who have undertaken a similar project 🙂
I would appreciate any information.

You can’t simply widen a house by 3 meters (10 feet). The existing walls need to remain in place.
At most, an extension is possible.
This is roughly what we had in mind:

Hello everyone,
Here is the starting point:
We can get a plot (600 m² (6460 sq ft)) with a 1960s house with 105 m² (1130 sq ft) of living space on two floors for 150,000 €. The land value alone (official land price) is 130,000 €.
However, the house is too small for us. We would like to carry out the following measures (the zoning plan allows everything):
1. Expand the house 3 meters (10 feet) to the back and 3 meters (10 feet) to the side.
2. Add another floor.
3. New roof.
4. New exterior facade.
5. Complete interior renovation.
In other words: we basically want to redo everything.
Would this be cost-effective, or would demolition and rebuild make more sense? Are there any tips regarding subsidies (KFW) or similar?
Sorry, I’m still a complete beginner in this. I know no one can give cost estimates here. But maybe there are people who have undertaken something similar 😉

Will this work?Short answer: no. But we can gladly tell you what is possible – your homework on this is in post #4.https://www.instagram.com/11antgmxde/

Summary: no. But we can gladly tell you what is possible – your homework is in post #4. Can you also explain why that is not possible? As I said, I am a complete beginner!

Can you also tell me why this isn’t possible? As mentioned, I’m a complete beginner!It can work if you like an L-shaped room that is 2 meters (6.6 feet) wide on one side and 3 meters (9.8 feet) wide on the other side. But 99.99% of homebuilders wouldn’t know what to do with it. Neither would I.
If you seriously want to know what is feasible, you need a structural engineer and an architect. For initial ideas about what might be possible, we need the current floor plans and an overview of the neighboring properties (keyword: building boundaries / setback lines).
To assess whether this makes sense compared to demolition, we would again need the current floor plans and your requirements regarding rooms and their use.
Without this information from you, we can only respond like @11ant.

Provide the exact year of construction, share photos, current and planned floor plans, and also a cross-section. in your grandfather’s files, you can check the building records at the building authority and request copies. THEN we can tell you what’s possible.

Does this work?No, because of the structural system. The floor slabs rest on the external walls, so you can’t simply remove them. Generally, the external walls need to stay in place. Door openings could still be made to access the extension with the 2m (6.5 ft) utility room.With a lot of money, it might be possible—if you had a listed facade or something similar—but demolishing and rebuilding is the route you want to take and also the most cost-effective for your plans.
Have you already purchased the plot, or is it the inherited one from your other thread? If building plots are still available in your area, it could be cheaper to move to a vacant lot without an existing building. You should get demolition quotes and compare them with other land options.
