What's the construction and thickness of the wall?

Yes, you'll need Building Regs approval for the structural opening and for the
window itself. You're not going to use the loft as a room are you? If so
you'll need to do a lot more work, like strengthening the floor and providing
Means of Escape in case of fire etc etc.

You should also talk to Planning, esp if you're in a conservation area or if the
window overlooks next door, and ask them if they need an application. Give them
a few more details than you've put on here though!

outer layer standard brick with a 70mm cavity and iner layer standard brick

Yes, you'll need Building Regs approval for the structural opening and for
the
window itself. You're not going to use the loft as a room are you? yes
sort of computer room
If so
you'll need to do a lot more work, like strengthening the floor (already
had permission for the floor and it has been approved
and providing
Means of Escape in case of fire etc etc
..well would this not be the window

Certain it's 70mm? The internal brick tells me it's a fairly old house and
cavities were virtually always 50mm in those days, although there could have
been some build inaccuracy or some bulging of the outside skin. Anyway, either
way the easiest way to do this is with a Catnic CN7A lintel (for 50mm cavity) or
CN3A (for 70mm). If you can slide the lintel up inside the cavity you could use
a CG50/100 or CG70/100 which saves a bit of work.

A Catnic is the best for this job as it does not need a separate cavity DPC
above. It's 150mm deep and needs to be min 300mm longer than the width of the
opening to give 150mm bearing each end. They come in 300mm increments in
length.

You're going to need an access tower and hire 1 or 2 Jackall wall supports from
HSS to support the wall while you cut out the bricks to insert the lintel.
These will save having to support the brickwork all the way down to ground
level.

see www.catnic.com and look for Products Lintels Cavity Wall Combined Box
Lintels or Open Back Lintels

Possibly not.

Escape Windows:

- An ‘Escape Window’ must be accessible via a ladder to assist rescue of the
occupants from the new room(s).
- Whether incorporated within a dormer or a roof light, it must have a clear
opening area of 0.33m2 with either the height or width being at least 450mm.
- The escape window should be within 1.7 metres of the eaves, measured along
the roof slope.
- The height of the sill of the vertical window should be between 800mm and
1100mm above the floor, and for a roof window between 600mm and 1100mm above
floor level.
