Does anybody know what size rsj's are needed for a garage conversion being knocked into the lounge - the size of the garage is 16 ft x 8ft. Once knocked through it will take the size of the room to 19ft x 16ft.
Building Control at The Council have to pass it anyway, so doubt they would pass a wrong rsj size. How much do structural engineers cost then jackthehat? I have been told almost a grand, perhaps I am wrong. Considering the conversion is only costing £5k seems quite high.
Queenie .......... it's not just the size they'll want to see, it's the calculations as well. They sometimes have them confirmed by another SE then.
If you don't know of anyone locally, I had some done online once, when I was in a hurry. It cost £150 for three beams, so £100 sounds about right.
They have to calculate the loading on the beam. It can vary from job to job.
