Renovating a half-timbered house - low ceiling heights, are there possibilities?

Remove every second ceiling, so between ground floor and upper floor and between attic and roof space, could that work?

Maybe.

If you really want to completely renovate, that is, to today's energy standards, unfortunately 200k is not much.

That was just said casually, I don't want to reach today's energy standards with that half-timbered house.

I asked you a (yes, amateurish) question, no reason to make fun of it.

Don’t make fun. Sometimes you have to write exaggeratedly for the intention to come across. I also added a detailed assessment and didn’t just laugh at you. You want to outsource the risk for a special property to the bank. That doesn’t work. You have to put up a lot of money in advance. And still have money in reserve, because unforeseen events are guaranteed to happen.

P.S. I estimate a suitable renovation of a half-timbered house to start at €1,500 per sqm of living space.

A conversation with an architect two weeks ago resulted in at least €2,500 if it is to be completely renovated and meet "new building standards." In my case, it is not even a half-timbered house, but a normal brick house with historic monument protection and built around 1920. Renovation costs including incidental expenses are roughly around €300k. By the way, the bank will also agree to financing, but only if detailed plans from an architect with cost calculations prepared by the architect are provided beforehand. For this planning (everything necessary for the monument office and building application, grants, KfW) the architect charges about €9k. If the property/existing house were not in equity, I would not do it. This results in an "advantage" compared to a newly marketed semi-detached house about 100m away with a significantly smaller garden of about €100-150k.

: The original poster will realize that as well, even if he does not want to renovate so extensively (and not under monument protection). But you will also receive a nice subsidy then.

I'll give my two cents as a former owner of [Fachwerk] and outbuildings like a barn and stable

"Collector's item" practically means that it is only suitable for a clientele who have the money and can afford to write it off as a flop. Indisputable ceiling height, timber framing on a vaulted cellar, change of use, a "grown" colorful ensemble of outbuildings: at least in total these are contraindications – at least for those not experienced (in severe cases) in renovation. In my assessment, this is clearly not a case for beginners; you can only get hurt. Overall, I would rather describe the property as contaminated than as developed (in my case just a personal opinion, but as a board member of a bank I would hardly think differently).
