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.

Thanks for that. Would that 50k have included the staircase build? (just that it would be unfinished?)
My next biggest unknown is budgeting to re-fit the existing bathroom. It's very small and would get rid of bath and have new sink, toilet, enclosed shower.
The door currently opens inward, which is a huge pain. Would there be any regs preventing it opening outward?

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.
