Ground floor approx. 100 sqm, upper floor expandable (planned bathroom, 2 children's rooms, 1 storage room)

How absurd is that? Of course, you have to plan the upper floor if you want to expand it. Whether that happens immediately or in 100 years doesn’t matter. The position of the stairs is crucial and is difficult to move even in 100 years. What knee wall height have you planned?

I would also reconsider the door situation. You find the rooms too narrow, but this narrow hallway, where you run up and down 1000 times a day, can be blocked with doors? Also nice when someone walks down there and then runs into a wall. That’s nonsense. The hallway is used much more often than the rooms. It has to remain clear.

Please no more discussions about the utility room. I think everyone here has accepted that by now.

Ah, that's what you mean. Yes, it might not be entirely to scale. However, the floor construction will probably be around 10 cm. Underfloor heating, dry screed, floor covering. A cousin has 9 cm. Also a wooden beam ceiling.

To represent it quite well to scale as a sketch, it helps to place a tracing paper over the ground floor drawing and trace the basic dimensions. Alternatively, good old baking parchment also works.

With the 10 cm floor construction, you have forgotten the wooden beam. Even with 10 cm construction, at 2.5 m section you only have just over 1.5 m passage height.

I would have no problem with the outward opening doors. Just move the bathroom door so that the bathroom door and the entrance door do not interfere with each other.

How is the insulation of the upper floor planned?

Is the utility room also prepared for future expansion? Is the electrical cabinet large enough? Can all other connections be easily routed upwards?

I would reconsider the door issue as well. Your rooms are too narrow, but this narrow hallway, where you run back and forth a thousand times a day, can be blocked with doors? Also nice if someone walks by and then gets stuck on the board in front of their head. That’s nonsense. The hallway is used much more frequently than the rooms. It has to remain free.

I know the staircase under the roof slope would have been more optimal, but then the ground floor wouldn’t have fit, and since the staircase is now relatively central, the space on both sides can be used and wasn’t a problem for us. I have to admit, though, that the topic was quickly settled for us. Maybe a mistake.

We’re still not sure about the knee wall. Basically high enough to fit a bed underneath, but especially I could also get along with a small one. There are nice solutions with shelves, for books for example. We’re completely open there and would choose a knee wall that best fits the room layout.

Hmm, you’re certainly right about the doors, it could be very annoying and the doors would, of course, always have to be closed, which also takes light from the hallway. We definitely have to rethink that.

Your hint about the ground floor almost prompted me to comment; I’m staying calm though.

To get a fairly good scale sketch, it helps to place tracing paper over the ground floor drawing and trace the basic dimensions. Alternatively, the good old wax paper works too.

With the 10 cm floor construction, you forgot the wooden beam. Even with 10 cm construction, you have just over 1.5 m head clearance with a 2.5 m opening.

I wouldn’t mind the outward-opening doors. Only move the bathroom door so that the bathroom door and entrance door don’t get in each other’s way.

Is the utility room also prepared for the future expansion? Is the electrical panel big enough? Can all other connections be easily routed upstairs?

I’ll measure the stairwell this evening, then I’ll have it more precisely.

The wooden beam ceiling construction is drywall sheets, counter battens, vapor barrier, 24 cm wool, roof boarding as tongue and groove.

We’re having empty conduits installed for electricity and plumbing going into the upper floor so the ceiling won’t have to be opened again later when it is expanded. The sizing of the devices and panels accounts for future expansion.

@Moderation: Thanks for adjusting the thread title. Please add 1 bedroom to the 2 children's rooms, bathroom, and 1 storage room on the [OG].

If you are already building, there must be a knee wall specified in the execution plans for the roof. You won't get approval without a finished plan. Or what do you mean by

Moinsens,
we are currently in the middle of the construction phase.

?

Nope, apparently not here. In our development plan, everything is allowed except for an apartment building or rental apartment, as long as the total height does not exceed 9.00 m. We could have even built pink roof tiles and a neon green exterior façade. Currently, we do not have a knee wall/dormer.

This is how it currently looks.



Or I'm just too dumb and don't get it right now.
