Internet is always wrong, don't trust it.
My neighbour got a pretty standard one done and it cost 55 I think, but it was a shit show as there was no overall design or project manager so the trades didn't give a shit and worked in isolation resulting in thresholds that don't match up (slight step up into one of the rooms), messy as hell external pipe runs and flashing that looks over sized and unfinished.
You could prob get something acceptable for a shade over that but make sure everything is coordinated.I'm planning on doing the same soonish so interested in how your experience pans out!

I assume you are London based? The last side-hustle L-dormer project I worked on was mid-2017. The dormer was near identically sized and planned to the estate agent plans above including rooflight/window quantities. The client ended up choosing a dormer specific company who priced the works at £50k (inc VAT).
Worth noting that the quote excluded:
- Planning and Building Control drawings (my role)
- Finishes throughout
- Bathroom/Sanitaryware
- Making good/Decoration from 1st floor hallway up to new 2nd floor
You will need to allow for the above and general inflation, so I would allow a decent bit of top of the above to cover everything.
- Planning and Building Control drawings (my role)

Mine without the back part (but with an ensuite), cost about £55k all-in (including decorating, carpets, bathroom suite, party wall, building control, etc) in early 2018. Could have knocked maybe £5k off with some cheaper options.

Anyone had an L-shaped dormer done recently? I’m about to get quotes and researching typical costs. Internet says ~£45k, although unsure what that would cover and what I’d need to budget for all-in, i.e. staircase, fittings etc.
It would more or less be the size of the loft in this floorplan.
