Truss Loft Conversion - Advice

[kickingk]

Hi, we have just started a loft conversion, and I have attached a picture of what the SE has advised, If you look at the picture, to get the head height as it is tight,
1) The I beams will be approx 1cm above the existing ceiling,
2) They will attach Flitch Beams in the middle by notchting the existing ceiling joists to keep the head heights then attaching thes from these I beams to the wall.
3) Then they will run new floor joists along the existing ceiling joists from the wall to the flitch beam. 6X2
4) These new joists will be tied to the existing ceiling joists to support the existing roof.

Im trying to get my head round it, as it is nothing like what I have read,

Can this be done?

There are many ways to crack a nut!

A flitch beam down the centre which is typically formed with an RSJ with timber inserted into the webs to support the ends of the new joists

Not saying you're wrong Fred, but I'd just call that a, erm, beam

A flitch beam is a length of flat plate on edge, restrained by timber either side to stop it buckling...

Yea fair enough Ronny, if you wanna get all technical on my ass!
