Start at the Archetect he will be able to give you a good indication of how much you should be looking to pay. I have done loads of lofts ranging from about 5k up to £28k it depends a lot on headroom on staircases, and in loftspace span of loft load bearing walls etc most of the money that goes into a loft conversion is on materials that will never be seen ie RSJ's and Insulation. depending on the property type you may also have to replace all habitable room doors with FD30 fire doors, fit mains smoke detectors and heat detector change 1st floor windows for fire escape possibility of removing cielings on 1st floor to gain headroom in loft. until you have a drawing in your hands, it is impossible to get an exact price hope this helps.

An `in the roof` velux type conversion will be about 10K inc. plans etc.
A dormer conversion around about 13/15K inc.
Thing is you really need plans to tie it down.
Allow about £1000 for plans. calculations & Building Control fees, then get your quotes.

Hi it does variy depending on building regulations, and structual engineer calculations, upon which materials, ie steel sizes timber sizes.

A good velux would be in the region of £10,000 upwards all in, depending on the above and to what standard of finish you require, but a full detailed quote, a free quote, this includes all drawings and calcs

hi , ive just done a two bedroom loft conversion with kite winding stairs for £8900
and that was 8 meters by 6 meters wide with 2 velux .
it all depends on the layout of your roof which playes a major factor inthe pricing and whether it will need steel beams to support the weight.
