Loft Conversions in Islington
LLAC has worked on loft conversions across Islington for years, from the Victorian terraces of Barnsbury and Canonbury to the Georgian streets of Highbury and the mixed housing of Holloway and Finsbury Park. If you're in N1 or the surrounding postcodes and want to add a bedroom, home office or bathroom in the roof, we can make it happen.
Types of Loft Conversion We Build in Islington
The most popular conversion in Islington is the L-shaped dormer — and for good reason. Most properties here are Victorian mid-terraces with a rear outrigger. An L-shaped dormer wraps around both the main roof and the outrigger, typically giving you 30–40m² of usable space — enough for a large bedroom with en suite, or two smaller rooms.
We also build:
Mansard conversions, ideal for properties in or near conservation areas, keeping a lower roofline profile while maximising headroom
Dormer conversions, a rear-facing box dormer that adds light and standing height
Velux / roof light conversions, the most affordable option, keeping the roofline intact
Planning Permission in Islington
Islington has over 30 conservation areas — including Barnsbury, Canonbury, Highbury Fields, Thornhill, Cloudesley and Tufnell Park. This means most loft conversions in Islington require full planning permission rather than permitted development rights.
LLAC handles planning applications as part of our full project management service. We know what Islington Council looks for and design conversions accordingly.
The Party Wall Act applies to almost every terraced and semi-detached property in the borough. We'll advise you on your obligations and help serve the correct notices before work begins.
