ᐅ Wall Thicknesses in Timber Frame Construction – Interior Walls and Exterior Walls?

Good day.

What are the typical thicknesses for exterior walls, load-bearing interior walls, and non-load-bearing interior walls in timber frame construction (energy saving regulation standard)?

We are planning to build an urban villa, and until then, I would like to create my own floor plan. For this, I want to have an approximate idea of the wall thicknesses I need to work with. I understand that there are certainly many options, but what are the most common wall thicknesses?

Best regards.

Take a look at the construction specifications provided by house manufacturers, for example Schwörerhaus, Weberhaus, Rensch-Haus.

For a good exterior wall, plan for about 38-44 cm (15-17 inches). Interior walls can vary depending on the structural requirements. Usually, they are at least 12 cm (5 inches), or 18-24 cm (7-10 inches) for load-bearing walls.

Thank you very much for the responses.

Don’t make it too complicated as a layperson, especially since it’s hard to know exactly where load-bearing walls should be. As a general rule, plan for 40cm (16 inches) exterior walls and 20cm (8 inches) interior walls. Be careful not to add just a few centimeters for fitting a specific piece of furniture. This way, you’ll have a solid basis to continue working from.

That way, you’ll end up with something you can work with.

I’d do it similarly.
Timber frame construction is slimmer than solid walls. For exterior walls with just plaster, I’d go with 34 cm (13 inches) and 15 cm (6 inches) for interior walls. There are no load-bearing walls, but necessary studs are integrated within the interior walls. Allowing some clearance everywhere is important when planning yourself. After all, you usually don’t place furniture directly against the wall, so there should be some space between. And 5 cm (2 inches) too much is better than 5 cm (2 inches) too little.
However, a word of caution: many prefab home manufacturers don’t allow many changes to their standard floor plans. So the contractor should already be decided, and the preferred design should be only slightly modified.
