ᐅ Conversion effort feasibility

Hello everyone,

This concerns a house built in 1971.
I have attached a floor plan with my proposed changes.
We would like to create a more open layout, meaning a large combined living and dining area.
Possibly by including the hallway in this space.

The current floors would need to be removed for this (approximately 30 sqm (323 sq ft) parquet strip flooring and approximately 50 sqm (538 sq ft) tiled floors).
We would prefer wooden floorboards.
Additionally, a large new exterior window, possibly floor-to-ceiling (top, marked in orange), would be great.

Now my questions:
- Is this kind of renovation even feasible (bearing walls, etc.)? Would it be necessary to leave support columns or similar?
- What approximate costs should be expected for:
- Demolishing walls
- Removing floors (about 25 sqm (269 sq ft) parquet strip flooring and about 50 sqm (538 sq ft) tiled floors)
- Purchasing and installing floorboards (about 70 sqm (753 sq ft))
- Installing a large exterior window

- Would you include the hallway in the open area, or rather not and only open the wall between the current child's room and the living room (considering heating costs, etc.)?
- Do you have better ideas for modernizing the layout?

It would be very helpful to get rough estimates of costs and also how long such work might take if doing it yourself, if possible (for example, the floors).

Thanks in advance!

Aside from the fact that I couldn’t open the attachment on my end, I would say that no one can really assess from a distance what is feasible (for example, load-bearing walls) and what costs you might face.
With an older building, there can definitely be some surprises that end up being expensive.
Consult a local professional and discuss the entire project with them (including your second question about insulation).

It works fine for me with the attachment, where exactly is the problem on your side?

One more thing: Who would be the professional to ask about this?
Is it possible to get a free cost estimate for something like this?

Hello,

I also can’t open the attachment...

You can easily find an expert in the business directory or through various websites of building surveyor associations.

Usually only the initial consultation is free—I assume you wouldn’t want to work for free either? An assessment of the existing condition and developing possible solutions takes quite a bit of time.

Kind regards

"Building expert" is probably the keyword here?

Well, the point is that I don’t own the house yet. I just wanted to roughly estimate in advance whether buying it is even worthwhile or if I can still afford the renovation afterwards.
