I am currently considering whether we should do a ground floor increase or not. Basically, we like high ceilings. However, we are somewhat uncertain about how much it will affect the upper floor. The maximum eaves height is 4.5m, so we are limited.

Without a ground floor increase, we would have a knee wall of about 1.28m on one side of the house and about 0.97m on the other side (due to ridge shift). With a ground floor increase, we would have about 1.15m and still 0.97m. Measurements are from the top edge of the finished floor. Since the rooms are quite long (about 5.5m), I am considering simply doing the ground floor increase and artificially reducing the knee wall with a drywall partition, or later installing built-in wardrobes along the roof slope.

The ground floor increase would mean 2.635m to 2.76m clear rough height.

What do you think about that?

Good evening,

how thick is the finished base slab - excl. covering, planned?

Hello, The floor slab (basement) is to be 28cm thick + 10cm XPS insulation underneath. In what way would you have to do with that? The house will not be higher, only the ground floor ceiling will be shifted. In other words, fewer bricks on top, but more below. It should also make no difference in terms of weight, right!?

I also like quite a lot, but that’s not why I have it.

What I want to say: you don’t have to have everything you like ;)
Whether a ceiling height increase is appealing or even necessary depends heavily on the floor plan; in some cases, the increase might not even be noticeable. I would also check the dependent lowering of the KS with a very sharp pencil. I wouldn’t want less than 1.25 KS for roof pitches under 30 degrees and room widths of about 3.50 on the upper floor.

Regards

@ Nothing at all; had no info that you are building with a basement. So, anew - how thick is the ceiling above the basement planned excluding the covering? Rhenish greetings from on the road Construction expert

Hmm, that's a good question. I need to find out. As far as I understand, that's determined by the structural engineer, who of course also needs to know whether an EG height increase is planned or not. I'll ask.
