In my opinion, this plan with the "children's floor" is completely going wrong... So you want to have an 11 sqm bedroom in the foreseeable future, and your bathroom is supposed to become the guest toilet? While the children reside upstairs in the palace? I always think it’s nice to prioritize the children, but you really don’t have to degrade yourselves to their lackeys, sorry.
I also find the study upstairs very small. Is it only used for the tax declaration or also for other purposes?
In the bathroom upstairs, the shower seems very small to me. Is it 80x80? If so, I would consider whether you could somehow get a larger, more modern, "more comfortable" shower size.
You don’t have a cloakroom area. I find that more than difficult with 5 people...
Overall, I think you have very small / few window surfaces. Was that planned intentionally?
We sleep in that room and get dressed there – for us the priorities are simply different there. Bigger would of course always be nicer, but at the moment we simply don’t see any possibilities given the available space and we also don’t want to cut back on the living room since we spend most of our time there... and whether we implement it will be looked at, so it’s only an option and an explanation why there is no very small guest room for 1-2 guests per year. We are still thinking about it, the plan sounded good in our minds to have peace down there.
The study upstairs will rather be a "storage room" for the vacuum cleaner, ... so not a room for a home office or similar where real work is done.
We will look at the shower again, it is planned to be walk-in.
You’re right about the cloakroom, it is supposed to be integrated into the utility room and more in the hallway for guests or for everyone’s daily jacket.
We haven’t planned the windows in detail yet, but that will also be added to the "check list."
