yes mate the window will be going right near the top what would you recommend
be aware, any brickwork near the top of the gable end will be very fragile. the weight of the ridge board will only press down on the brickwork if the roof has spread a little. be very wary if you have an open ceiling with metal ridge though!!
how do you mean should i fit some kind of lintal i was thinking of some sort of metal strip as there isnt that much weight in the bricks plus its such a small window only 450 mm accross probley only 2.5 bricks accross
always assume the worst. a traditional roof with rafters, ridgeboard, purlins and joists, ( as opposed to trusses, wich have no ridgeboard) will support the weight of its own ridge board, the brick and block work is only cosmetic, until the roof spreads a little, then some weight can come down onto the masonry. i would fit a regular steel, cavity spec lintel in case of any later settlement, i.e. catnic cn7, birtley cb 70 etc.
Best to check with BCO first as there are rules & regulations on this to do with fire spreading out the window. I think it used to be 2m (?).
Might be easier to fit velux window with air-vent type and open it on a hot day

there are about 11 houses same as mine done this i no you should get regs but!!! any way by looking at some of them they have no lintal there is only one house i can see which has a concrete one but all these windows are larger .. i was also thinking of fitting a skylight window as they come 450 wide and my rafters are 440 so bit of adjustment needed but was going to see just how much light is given with the small window first as im only going to put the pc up there
