Are these roof members structural support?

You absolutely need to engage an engineer. Ignoring those braces, which may or may not be relevant, your ceiling joists tie the outer walls together and keep them from bowing outward. As an aside, ...

Are these roof members structural support?

That looks like an old house, with the original roof sheathing made out of boards instead of plywood or OSB. The rafters, however, look like 2x6 or 2x8s and not the usual 5x5 rough sawn lumber with ...

Reframing Engineering Roof Truss System for attic conversion

That could have been a great second floor if it was framed that way. With the high pitch roof you have, it had high potential. In my opinion, you will be better off removing the whole roof system and ...

Should there be a junction box for each outlet?

Use residential raceway and (if you want) boxes and outlets designed for it. This achieves your "B" in a way that looks attractive and doesn't need painting. A couple of examples of US-type ...

2x6 joists at the span that you are talking about (16' and 18') are not strong enough to support a floor as a living space. With a span like that the timber size that you sister in would have to be at ...

What insulation should I use in the ceiling of my attic

Use polyisocyanurate sheet foam insulation for that part, which is (I believe) still the best insulation value per inch available to mere mortals with budgets. If you don't have a budget, aerogel.. ...

2x4 floor joists in attic: make stronger/level?

Usually you'd add new joists of the correct size, in between (but not fastened too) the old joists. Pack them up slightly off the wallplate (10mm or so) so any flex in the new joists won't touch the ...

Adding "floor" to unfinished attic with blown-in insulation

You don’t give us all the info we need, but I’ll make some assumptions and you let me know if I’m wrong. The roof and ceiling structure is what we call “stick framing” it is not framed with trusses. ...

Any tips on keeping straight lines in drywall on ceiling with multiple angles?

You always start with the ceiling boards first. Then the vertical wall boards help hold the edges of the ceiling boards up. Tape and mud. If you have cut the boards fairly straight, the edge lines ...

Ceiling joists hung below top plate

One old technique that might work here is the “let in ribbon” or “cut in ribband”. This traditional method was used in “balloon framing”. Before the wide adaptation of “platform framing” with the ...

Loft Insulation Alternatives (UK)

2 angle braces on attic of a gable roof

It’s difficult to see, but I suspect your gable end wall is not ballooned framed, but rather has a double top plate. This creates a “hinge” in the wall. The diagonal braces keep the end wall from ...

2x4 floor joists in attic: make stronger/level?
