Newbie here. Waiting to here opinion back from SE, but interested in opinions here.
Small kitchen extension on back of bungalow. 8 ft/2.4 m in depth, width 3.6 m, which is also the way the rafters run. It’s a gable end and we are looking to vault the ceiling.
Ceiling joists run in opposite direction to rafters, so do not act as rafter ties. At the far end/gable wall end, there is a 45x90 timber beam running across between the rafters it’s bang on midway between ceiling and ridge , at 2 ft height it falls between not being a rafter tie of collar tie. The beam at gable end can stay. At the opposite end, 8 ft away, the only support is a timber post sitting on -I assume - a load bearing wall. This takes the weight of the ridge board.
Midway is another 45x90mm joist running between 2 rafters again at 2 ft/mid height between ceding and ridge.
In an ideal world I would like to remove this, and have a velux either side.
Is it feasible to remove that joist, and maybe use 4/6/8x2 further up towards the ridge as a larger collar tie?
Could I also place lateral support ties from across wallplate, and fixed down the wall?
On the existing plan of house, A & C will stay. Just ideally B could go.
Because of the adjoins wall on the left side, would that limit spread, as effectively acts as a buttress - kind of? The wall opposite has no support, other than it maybe gaining mor resistance to spread by definition of being tied into the return/corner of the property.
Happy to be told if I’m talking/thinking nonsense…
