Own work - floor coverings, painting, tiling, what else?

Just casually: Vinyl is not always cut with the cutter. We have now chosen some with an HDF carrier board.

What I have often read is that when building turnkey and "removing" services, it often is not worthwhile. The construction company often profits from the removal of services... We build solidly with an architect and individual trade contracts. So if we do not commission a job (e.g., flooring), we save the full cost. Furthermore, it should be a combination of 1. a time-consuming activity (labor) that one 2. also "masters" oneself. I always like it very much when afterwards people complain that it is not 130% perfect and blame the helpers for it.

I prefer a middle way here. In my opinion, the price-performance ratio is best when you have a skilled worker doing the fine work and the "helpers" working under his instructions. You save slightly less than if you do everything yourself, but the result is often better and in tricky spots, this person also knows what to do...

Exactly, those are the ones I mean! Score with a cutter and then snap, gives super clean edges and even works at a 90 degree angle

Oh? Cool - nice to know!!!

I prefer a middle ground here. In my opinion, the price-performance ratio is best when you have a skilled worker doing the fine work and the "helpers" working under their supervision.

The tricky spots are always the reason why you need the professionals. Anyone can stack and glue the big aerated concrete blocks on top of each other after 10 minutes of training. But not everyone can do the corners, etc... only those difficult positions are the ones where later defects/problems will occur (mold, statics, leaks, etc...). That's why your idea is indeed the best decision. Bring in the specialist, but only let them do the special tasks while you/friends/relatives take care of the grunt work. I can only say about our construction period that besides my job from 6 a.m. to 5 p.m. daily (except Fridays until 2 p.m.), I spent about 15-20 hours per week on the construction for administration, paying bills, and also selecting things or making certain decisions. Because there is always something new to choose and plan. Almost all Saturdays were spent on visiting show houses or obtaining offers, etc... there was absolutely no time for major DIY work. We laid speaker cables ourselves after the electrician chased grooves for us. I just taped the speaker cables together with his cables and that was it. Now I have in-wall speakers without any visible cables (home theater with projector, woohoo). But it was a lot of effort to plan exactly so that it looks decent in the end.

With my best friend, for example, we plastered the entire house ourselves (inside). In the basement, we did everything ourselves. In the living rooms, we then mixed and applied the plaster with 4 "helpers," and a "professional" did the finishing and the tricky spots.

This way, you save money, time, and the result is also right. If you do everything yourself, you need a lot of time exactly at these points, and the result is usually not 100%. Electricity is the same. The electrician marks where what should be. Chasing grooves, laying empty conduits, and pulling in cables can then also be done yourself. Just talk to the craftsmen; they usually like doing that. With their schedules being full right now, they are glad to earn money on materials, have the homeowner do the work, and still be able to take on another job themselves....
