ᐅ Replace Load-Bearing Interior Partition in a Prefabricated Timber Frame House

A good carpentry company can handle this with a structural engineer. Most prefabricated house manufacturers do not do this, as it is not of interest to them.

Do you have a rough idea of how much something like this would cost?
The dimensions are 90cm (35 inches) passage, then a 196cm (77 inches) wall, and then another 90cm (35 inches) passage... The wall itself is 17cm (7 inches) thick and is marked with a wooden beam as a support beam. Unfortunately, the photo cannot be uploaded.

It is naturally hard to say. The structural engineer usually charges 500–800€ (about 540–860 USD), but if they receive the framing plan from the builder, it might be 300–500€ (about 320–540 USD). Supporting the structure over the full width could cost 2,000–4,000€ (about 2,160–4,320 USD), but it might also be cheaper. I know someone who only paid 2,600€ (about 2,800 USD) in total and had no problems.

Ok, well, we’ll have to check that out. Thanks a lot already 🙂

Without plans from the house manufacturer, the entire structural engineering might need to be recalculated. However, a good manufacturer will provide the structural calculations during construction and also hand over the fabrication plan. The more information you can get, the better.

Steel in timber frame construction is actually quite common. I have used several HEA and HEB beams as concealed support beams and to transfer the load from a dormer.
