Removing all internal walls tomorrow!
Discussion
Tomorrow is Demolition day for the interior of our 70's bungalow. Engineer says it's got a self supporting roof, architect says it's a trussed roof, I've looked and seen plasterboard bewteen the tops of the internal walls and the ceiling/roof so it must have been plastered before internal walls went up.
Still seems odd though - anything I should watch out for?! Internal walls are currently block. Should I get some props in just in case?

t out of it!
Trussed rafters - self supporting - were only introduced in the 70's I think.
Hope the early ones were up to it
Edited to add - are they self supporting? I'd have thought they'd be tied into the stud walls at some point, possibly mid-span. Eurgh.
Go for it - just stand as near to the door as possible when you take the last wall out.

Beat out all the plasterboard then start cutting the studs. Start from the middle of the wall and work out alternately until all are cut. If the wall is supporting any weight then your earlier saw cuts will close up. A push up from below will show how much load it takes to free the cut stud. If you can't push it up on your own then I would say the walls are supporting the roof.
Not a professional, just a safe approach rather than crash and burn.

Sound advice there, Steve!Not a professional, just a safe approach rather than crash and burn.

I believe its a long way to A&E from this particular bungalow too!
The roof is (from memory) is made up of 2x4 across the span (the actual ceiling) and some bigger stuff below the tiles and tied to the span. Distance between the rafters is about 18".
ALL internal walls are block. All internal walls meet the ceiling below the plasterboard so ceiling was built before the internal walls. Maybe i'll leave a wall running down the middle of the house, just in case, at least until we start building new stud walls.

I don't know the calculations (someone will be along soon who does, no doubt), but I wouldn't like 2 x 4 across the 7m span.I guess the height (and obviously the pitch) of the roof would make a difference though.
It's not really the size of the timbers in a truss that's important but the design.
7m is not that big a deal with trussed roofs, and they don't draw support from internal walls, well, very rarely and that's in certain specific and rather unusual circumstances.
1970's bungalow.....no chance. Why would they? To do that would mean that the internal wall became load bearing, which in turn would have meant a foundation was required below the wall. Non loadbearing block walls in a bungalow will just be sitting on the floor slab.
The ceiling over the top of the walls is the real clincher though.
Kinda fun knocking things down though!
