Islington’s Georgian and Victorian terraces around Barnsbury, Canonbury and Highbury are some of the most characterful in London, and also some of the most tightly protected. Many sit in conservation areas or under Article 4 directions, so a mansard loft conversion or a wrap-around extension usually needs full planning permission, and the design has to respect the original facade.
We work across N1, N4, N5, N7, N19 and EC1. For Islington homes we tend to recommend a mansard where the roof slope faces the street and a rear dormer where it does not, and we match sash windows, cornices and brickwork to the existing house so the new work reads as original.
Loft conversions and house extensions in Islington
Islington projects often combine a loft conversion with a lower-ground or side-return extension to create a kitchen-dining space at the back. Because these homes are usually mid-terrace, the Party Wall etc. Act 1996 applies to almost every job, and we handle the notices and the surveyor.
Do you need planning permission in Islington?
Much of Islington is covered by conservation areas and Article 4 directions, so loft and extension designs frequently need a planning application and a design that suits the period property. We prepare the drawings, submit the application and deal with the council. Every project also needs building regulations approval, which we manage.
