Islington

Victorian terraces in Islington all have the same problems. Narrow side returns that eat up half the kitchen. Dark ground floors. Tiny bathrooms upstairs. We fix those things - and we do it without losing what makes the house worth living in.

What We Do in Islington

Extensions and conversions for Victorian and Georgian homes

The typical Islington project starts in the kitchen. A side return extension opens up that narrow galley layout and turns a cramped room into somewhere the whole family actually uses. Add some proper glazing at the back and the ground floor goes from dark to flooded with light.

Rear extensions work the same way. They push the living space out towards the garden and create the kind of open kitchen-dining room that makes a terrace house feel twice the size. Upstairs, a loft conversion adds a bedroom and bathroom without changing the footprint of the building.

We handle the whole thing - design, planning, building regulations, construction. One team from start to finish.

Local Knowledge

We know Islington and its planning rules

Islington is one of the most conservation-heavy boroughs in London. Large parts of Canonbury, Highbury, Barnsbury and Angel fall within conservation areas, and many streets have Article 4 Directions that strip away your permitted development rights. That does not mean you can not extend or convert - it just means the planning application needs to be done properly.

We know what Islington Council tends to approve and what they push back on. Rear extensions with contemporary glazing generally go through well. Loft dormers need careful design, especially on front-facing elevations. Side returns are almost always supported as long as the design respects the existing terrace rhythm.

Each neighbourhood has its own character. Georgian squares in Barnsbury are treated differently to Victorian streets in Highbury Fields. The terraces around Angel have different constraints again. Knowing those differences is the difference between a smooth approval and months of back-and-forth.

We are an architecture and construction studio, which means one team handles everything under one roof. No separate builder to find, no finger-pointing between architect and contractor. One contract, one point of contact, from sketch to keys.

Common Questions

Architecture in Islington - answered

Do I need planning permission for an extension in Islington? +
It depends on the property and its location. Islington Council has conservation areas covering much of the borough, and many streets are subject to Article 4 Directions that remove permitted development rights. This means even smaller extensions often require a full planning application. We check the planning position for every property at the start of a project so you know exactly what is needed.
How much does a house extension cost in Islington? +
Construction costs in Islington typically run between £2,500 and £4,000 per square metre, depending on the specification and complexity. A typical rear extension to a Victorian terrace in Islington costs between £80,000 and £180,000 including finishes. We provide a detailed cost estimate at the start of every project so there are no surprises.
Can I do a loft conversion on my Victorian terrace in Islington? +
Yes, in most cases. Dormer conversions are the most common type on Victorian terraces in Islington, adding a full-height bedroom and bathroom within the roof space. L-shaped dormers are popular where the roof allows, as they maximise floor area. If your property is in a conservation area, there may be restrictions on dormer size and positioning, particularly on the front elevation. We design around these constraints.
What areas near Islington does Rosace also cover? +
We work across North and East London alongside Islington. This includes Hackney, Camden, Stoke Newington, Dalston and Finsbury Park. We also take on projects in other parts of London and selected locations outside the capital.
