complete renovation of an old single-family house

Hello, I am new here in the forum and have a basic question about [Altbau-Sanierung]. I intend to completely renovate an older single-family house. Now, of course, the basic question for me is how to proceed exactly in order, or where to actually "start," if I may put it simply. Which "plan" can you recommend to me? You don't want to get into a fiasco! Thanks in advance for your answers!!!!!! Regards Alexander!!!

Hello! First question: has the house already been purchased? If not, definitely go through the house with a professional and check the condition! Secondly, it is questionable what exactly needs to be done and should be done. Should the floor plan be changed? Typical and expensive for old buildings are: Water/sewage new Electric completely Heating completely Roof truss OK? Covering including insulation Bathrooms anyway Walls/ceilings/floors Windows Facade Basement dry? But: since you obviously have no experience, I advise you to consult an architect with old building experience. Also an energy consultant. Another member here recently started a topic in which he described how he did it without a plan (and managed well). The basic procedure is basically, everything out and then everything new from inside to outside and from top to bottom. However, there are certain things to consider that one should be aware of. Overall too extensive to present briefly here. Specific questions are better answered

I see little chance of success for the project

Hello Joedreck,
thank you very much for your quick reply to my question here in the forum.
I already live in the house in question and now finally want to undertake a complete renovation to bring the living quality up to a modern standard.
The more and the closer you deal with the matter, the more you realize that it is not that simple !!!!
The house must remain habitable during all the work.
I think your idea of having a professional take a look at it immediately beforehand is a good idea.
Where can you actually find such a professional?
Does it have to be an architect right away?
Under which category do I find the thread you mentioned where someone has carried out a similar project?
I could certainly get one or two pieces of advice there.
My idea would be to possibly start with a new heating system in the basement, which can later be expanded with solar panels on the roof.
But even here the question arises, for example, whether I should install radiators or perhaps go straight for underfloor heating.
Would you also see this proposal to start with the heating system that way?

Regards Alexander !!!

Note:
why do the "bankers from Hesse" always have to see everything so negatively? At some point you have to tackle the matter, and nothing comes from nothing, as the saying goes so nicely !!!!

Take a look in my thread (I only have one). There you will find my renovation project.

If you want to live in it, it gets much more difficult. Do you have 2 floors so that you can live on one and renovate the other? Otherwise, it will always turn out badly and you will never finish because you have to keep moving your stuff back and forth.

Best to completely gut and rebuild one floor first.

If the roof needs to be replaced, definitely start with that.

I would do the heating itself last.
Write more about the house and also something regarding your budget.
There are also building experts.
If you also want to renovate energetically, you can consider the KfW with the energy consultants listed there for financing.

If it is supposed to be good and there is a lot of money available then:

Insulate the roof including the top floor ceiling
Facade insulation
New windows or glass
Insulate basement ceiling
Remove screed, install underfloor heating with screed including heat load calculation
Last the new heating, which really fits..

If you first replace the heating and then start insulating, it will be significantly too large and cycle frequently. That is inefficient and wear increases significantly.

And exactly for that reason you need a professional to accompany you in the planning.

Or a year of intensive research and subsequent planning.

Just quickly here I can share experiences with you. But as you see, even that takes time.. I like to do it, but I am also just an interested layman with my own experiences.
