Thread: Is this a structural internal wall

I suspect it's impossible to tell from the information available on those plans. It looks like the rafters are 150 x 45 LVL's @ 600 centres, but we don't know what the span or roof load is. It appears from what you've provided that there are a couple of rafter spans in that roof section that are only supported at the ends, but to offer an opinion without further info. would be a bold step. The roof may have been designed by a structural engineer as a unit. If the wall is load bearing can the 112 x 112 laminated post in the living room and the 230 x 65 laminated beam it supports support any additional loads? Who knows?

Call in the experts to have a look.

Good advice!

Without the drawings for Section's A, B & C its a guessing game.

Best approach is to contact your local authority / building certifier to obtain the "approved" plans and structural engineers report for the previous renovations, and the certifying authorities inspection report / approval sign off. That will have all the info you require, then its only a matter of verifying that nothing has changed.

Given the "150 x 45 LVL @ 600 max crs" note and that the rafters span the whole of that Family / Bedroom / Deck area its probable that the wall may not be load bearing - however it may be a bracing wall for wind loading.

Do not rely on your plans or the ones the council has on file, they don’t necessarily reflect what actually happened on site. Changes get made all the time that are not documented on file
Use the plans by all means as a guide but you really need to get in the roof / remove a sheet etc if necessary to confirm what is there and how it is supported.

If the premise of the question is to see if you can remove or create an opening in the wall I don’t see that as being an issue. An appropriate lintel beam can be installed if necessary to support the load.

Thanks all

Advice really appreciated.

I have to get some external work approved so will add removal of this wall to the plans. A lintel will be fine, as there is another one on the opposite side of the room near the kitchen so it will not look out of place.

Cheers!
