Extension advice (bits & bobs)
Discussion
Just started the footings on our new lounge.
Couple of things bugging me, nothing stated on the plans either (no surprise!)
We want a rooflight, as shown here http://www.visionrooflights.co.uk/gallery.php?albu...
2000 x 1000 in the middle of the room. However, it's 70kgs, and the roof joists are supposed to be 400 centres? how do you go about that when there's a 1000 window in the way?
Secondly, any thoughts on a layout? We're thinking about a woodburner in the middle (where shown) but may be more suitable on the same wall as the utility? (only other option) But then having the tv on that small wall in the middle may look daft? Any thoughts welcome?
Cheers

I would suggest that there the detail you are looking for is missing as these are architectural plans not something from the structural engineer?
With regards the ceiling joists, again the structural engineer will give the definitive answer. But a rule of thumb would be to have double joists running parallel to the window, with the intervening joist(s) cut off and horizontals attached across at 90 degrees (if that makes sense?)
That said, I'm no professional...

Yep, those plans would be used for PP not Building Regs/Structural. You need detail plans for anything involving non standard lintels, beams ext. You might even need steels to support that. Its not that costly to do, you just need to make sure its all calculated properly and your builder knows what needed.With regards the ceiling joists, again the structural engineer will give the definitive answer.

Don't just assume that your builder will know what to do BTW. Its your responsibilty to provide the detail to the builder. They are just there to do the donkey work. If you leave it to the builder they will just put the easiest option in
Is the roof light a feature, or do you feel you need the extra light? Our lounge is almost exactly the same size as that, and has windows in the same place, we get plenty of light.

We've got a kitchen in the middle (north of the utility) which will end up being pretty dark, so it's going to be a feature and there for the light.Don't just assume that your builder will know what to do BTW.

70kgs doesn't seem that heavy in the grand scheme of things.
More curious on how I approach the 400 centres thing? If someone wouldn't mind sketching how they might look? MSPaint is ace!

You trim the joists around the opening for the rooflight.
Would look similar to this, although there may well be some doubling up of joists
You might need steels aswell on that as at 5.5m you are stretching the maximum you would want to do with timber as timber would get rather bouncy over that sort of distance. so you might need steels either side of the long side wall to wall ie 5503 side and then the trimmers in steel as well along the 6m side, hope that make sense???Would look similar to this, although there may well be some doubling up of joists
