Our floor plan design for an affordable house

For us, it was the good Ivar cupboards that were installed as stair railings. It was no rocket science for somewhat skilled craftsmen from our circle of acquaintances. A nice board on top and done. You really have to be a bit more creative – and not insist on custom-made furniture from a possibly expensive cabinetmaker. They are usually really top-quality (there have already been so many beautiful pictures in the forum that made me a bit jealous), but you can't always afford them. There are other options.

But for 1 year every weekend and the annual vacation as well. Planned self-performed work: drainage on the property, pouring the base slab (actually!), building the roof structure (nail plate trusses) (I really have no clue about these two points, but my father-in-law is sure that he and my boyfriend can do it themselves with support), drywall & insulation, heating and sanitary installation including underfloor heating, floors (except tiles), possibly facade cladding, exterior work anyway (building a terrace, building a carport, that can also be 2-3 years later).

Well, I hope you’re not overestimating yourselves. We only did the electrical work ourselves and painted. We had 6 (!) helpers from the family. It cost us the whole annual vacation, several weekends, and a damaged foot.

maybe you could break down where you spent most of the time?

The three of us prepared the electrics throughout the whole house in 2.5 days (sockets, switches, network, thermostats, drilling for lamps, plastering, and chasing). Maybe I underestimate the time required for the rest of the electrical work, but 8 people with annual leave and several weekends for electrics and painting seems like a lot to me. But without knowing exactly what was done during that time, you can't realistically estimate it either.

Work speed always has a lot to do with experience and routine. Those who have a skilled environment that is closer to one trade or another make faster progress than someone who also produces good work as a result but has to figure out the individual steps and processes largely on their own and ends up in one or another dead end of complexity. Good tools are also a significant time factor.

I myself am rather slow and constantly have all kinds of ideas when I just start working. If I take the time to plan, everything goes faster, even if I ask a lot of questions and do research. Once I have internalized the plan based on my experience, I am very fast.

my father-in-law is sure

and my father-in-law is installing it

Your optimism and enthusiasm are all well and good, but you are entrusting numerous critical trades to your father-in-law. I hope you have something in reserve in case he is no longer so sure at some point or can no longer contribute as planned for other reasons. Botched work on the foundation slab and gas boiler can end catastrophically.

sure, everyone works at their own pace. But if I roughly estimate:

30 days vacation for the builder (male and female) plus several weekends for the 6 helpers: could be a lot, I'll assume 10

Annual vacation for builder (male and female) 10h*30days*2= 600h
10 weekends helpers 10h*20days*6=1200h

I come to 1800h. As I said, the scope of the work is not clear at all, all good. I just meant that it seems like a lot to me and therefore asked if Kaho674 can provide something more precise
