Hello everyone,
we are quite far along in planning our dream house. We want to build a single-family home using T9 bricks (36.5cm (14 inches)) in a Tuscan style.

Now we are stuck on the thickness of the interior walls. I have read in many forums that it is perfectly fine for load-bearing walls to be 17.5–24cm (7–9½ inches) thick and the other walls 11.5cm (4½ inches). This seems quite thin to me.

My builder considers these wall thicknesses perfectly fine. What do the experts here in the forum think about this? I would feel more comfortable if the load-bearing walls were 24cm (9½ inches) thick and all other walls 17.5cm (7 inches). What would be the downside to that? Is it just a waste of space?

Thanks in advance for your answers.

Why? The others do not carry load, they only divide space.

Thanks in advance for the answers.

Additionally, unnecessary costs are built in. (More costs for less living space)

Hello ypg,

Thank you for your reply. Am I correct in understanding that it is quite normal for non-load-bearing interior walls to be only 11.5cm (4.5 inches) to 17.5cm (7 inches) thick? I currently live in an older house where the walls are quite thick, so 11.5cm (4.5 inches) or 17.5cm (7 inches) seemed thin to me.

Best regards
Y

I don’t measure the walls in every house, but I always notice when a door frame is 24cm (9.5 inches) deep — doors are also found in load-bearing walls, after all... 24cm (9.5 inches) is quite something. Professionally, I look at floor plans very often... these almost always show (with a few exceptions or for load-bearing walls) dimensions of 11.5cm (4.5 inches). I think you are worrying unnecessarily.

Thank you, ypg, now I am relieved again.
