Own contribution - what did you do and would you do it again?

Hello!

We did the painting work (incl. filling), doors and floor coverings (excl. tiles on the ground floor and bathrooms) ourselves. We are also doing the outdoor areas.

and one00: you have no idea what you can do (if you want to)...

and one00: you have no idea what you can do (if you want)...

Wanting is one thing, whether you can acquire the knowledge in a short time, apply this knowledge, and have the time for it is another question.

Want another example:
We and many others in our residential area have made the attics accessible as storage space ourselves. I had previously read extensively about the issue of moisture. There was repeatedly the advice to use tongue-and-groove boards and not OSB panels or to ventilate accordingly.
Many took the easy way and simply laid OSB panels without a substructure.
That is certainly faster, also looks great at first, but what will happen in a few months or years, no one knows. It can work well, but it doesn't have to.

What does the example have to do with self-performance? Many craftsmen also lay OSB boards - even though the topic is well known.

If you lay [ESB-Platten], then you won't have any problems with all the advantages of OSB.

What does the example have to do with personal contribution?

He laid the tongue and groove planks.

That a personal contribution - provided one claims to do the whole thing professionally, which I assume in any case - must be preceded by an intensive engagement with the topic should be clear to everyone. Just watching three YouTube videos and then believing you know how to properly carry out roof insulation can also go seriously wrong. Blindly trusting every supposed expert, however, can as well

What we did:
Soil replacement
Floor slab including perimeter insulation and waterproofing
House connection: wastewater, rainwater, empty conduits for electrical and telephone connection
Prefabricated ceilings including reinforcement and concrete
Electrical cables installed, boxes for ceiling spots built into prefabricated ceiling (24 pcs)
Planned and installed controlled residential ventilation
Roof and screed insulation
Vapor barrier
Drywall including filling
Painting and wallpapering work
Interior plaster including filling (Q3)
ETICS facade
Interior and exterior window sills
Interior doors
Retaining wall shuttered and concreted (44 linear meters)
Scaffold rebuilt for craftsmen (3 times)
etc.

It is easier to list what I subcontracted:
Masonry (helped), roof (helped), electrical cabinet, sanitary and heating, screed (helped), flooring, tiles, windows and front door (due to warranty)
