Local knowledge
What we know about building in Islington
Housing stock
Four-storey Georgian terraces with lower ground floors, Victorian terraces in Highbury and Holloway, converted flats and warehouse conversions around Clerkenwell.
Planning and permitted development
Around half of Islington is in a conservation area and the council has detailed guidance on rear extensions, roof additions and basements. Permitted development rights for roof extensions are often removed, so most lofts need full planning. We design to Islington's Urban Design Guide.

- Can I add a mansard roof extension in Islington?
- Mansards are often the only acceptable roof extension on Islington terraces and are supported where there is an existing pattern of mansards in the street. They always require planning permission. Budget £80,000–£120,000 including the new floor and staircase.
