Hello,

today I would like to ask you again for what you do best: bringing a layperson’s naive ideas back down to reality.

I hope the attached calculation is at least somewhat self-explanatory. It might be worth mentioning that in the estimates (h=hours, d=days, w=weeks) I have already taken the number of helpers into account. So these are not man-hours/days/weeks.

Many of you probably have more practical experience: would you consider these figures roughly realistic? Most of the tasks (those listed with 1.5 people) I will do more or less alone, with my wife as an assistant. There might be more active helpers, but I’m not counting on that for now. At least for the trades involved, I’m reasonably skilled but not exactly fast—at least until I get into a routine, then I can speed up quite a bit.

Best regards

For example, check with the Association of Private Homeowners, which estimates 125 hours for painting and wallpapering work. They allocate many more hours than you.

This house is being built with a lot of self-help. Many relatives, friends, and acquaintances are skilled tradespeople. Work can only be done in the evenings and on Saturdays, so they expect a construction period of about one year.

Thank you for your input; I knew I could count on you when it comes to tempering naivety [emoji6]

I think the point about transport and procurement is very valid, and I hadn’t actually factored that in. I will also include trips between the apartment and the construction site.

Google for example the Private Building Owners Association, they estimate 125 hours for painting and wallpapering work.

Are those man-hours or for a four-person team? Wallpapering isn’t part of the plan for now. My numbers were gathered from various sources, and they mostly suggested around 100 hours. However, quite a few people here in the forum mention several weeks. My estimate is four people times 63 hours.

What I would really like to know is what realistic efforts would be, regardless of the timeframe in which the work is done. That scheduling will come afterward.
Do you really think 22 hours per week is too much? Honestly, I’m currently spending about 50 hours per week on the house project, simply because I enjoy it and have the time. Of course, that enjoyment will likely decrease significantly during construction, I don’t kid myself about that. Also, it’s not just the 22 hours of manual work, but alongside that there are still various clarifications and other tasks ongoing.

Travel time between apartment and house, procurement, downtime due to illness, appointments—all of these add up.
You still have work to do.

Keep in mind that the times do not account for a 4-person team. However, this does not significantly reduce the total number of hours required.
You also need to consider that helpers are not on site every free minute, and generally, you won't reach 22 hours per week.

The house has approximately 140 sqm (1,507 sq ft) of living space. For electrical work, a total of 130 years of experience are available for advice and planning, thanks to several relatives in this field. However, they will hardly be able to assist with the actual installation.

Sorry, but the electrical situation really worries me. So the dads are constantly acting as construction supervisors for you? Or are you just going ahead on your own? In my family, when it comes to water and electricity, the advice was always to let professionals handle it.

Also consider the preparation and follow-up... if you work a 4-hour shift during the week, you will spend 0.75 hours preparing and 0.75 hours following up, leaving only 2.5 hours of actual work. This means that out of 12 hours per week, you will only have 7.5 hours of effective work time.

From my own experience, the electrical work is probably underestimated as well. It really is quite time-consuming.^^
