You need to ask a structural engineer. You cannot cut out these timbers without full support.

If this a new build house you will likely need to go through full planning application with the council as there is can be restrjctikns on permitted development rights on new builds. You will definitely need full architectural drawings & engineer calculations for steels & as it’s a terraced house you will need partywall agreement drawn up with your neighbour as whatever work you do will have an effect on their house too.

Very difficult as no external gables to support ridge beam. Those roofs are built with the triangle principle so they cannot be cut without new supports.
I designed one as the clients had the bungalow left to them. We built internal pillars on each gable.but access was bad so the steel ridge purlin was hard to get in.

We are converting our loft in a 9 year old house. It’s taken 11 steel beams, loads of reinforcement of absolutely everything. Looking at your pic you will struggle with head height before even looking at getting a set of stairs up there. Looking at what you’ve got and it being terraced I’d probably just move house lol

It’s a trussed roof, so not something simple you just just guess.
Even a simpler roof needs designing by a structural engineer.

OK, I’m a structural engineer and have done a few of these.
You will need steel beams in the floor to pick up new floor joists, a knee wall on those beams to support the rafters at the node points (where the struts join the rafters) A ridge beam isn’t required when two supports are provided to the rafters.
