Islington's Housing Stock: What We're Actually Working With

Islington's homes fall into three distinct types, and each one comes with a different set of rules and a different set of problems. We treat them differently because Islington Council does too.

• Georgian terraces (Barnsbury, Canonbury, Canonbury Square, Duncan Terrace and Colebrooke Row): Three and four-storey stock-brick terraces, rendered ground floors, built as complete architectural compositions. Most work here, even a rear kitchen extension, needs full planning permission, and the council is particularly protective of rear gardens and the mews-lane pattern behind these streets.
• Victorian terraces (Highbury, Tufnell Park, Holloway, Finsbury Park): The bulk of Islington's housing. Two and three-storey terraces, many with an original rear outrigger, the narrow single-storey projection that used to house a scullery. Kitchen extensions here usually mean either infilling alongside the outrigger, building behind it, or both, and the council treats that differently from a flush new rear wall.
• Converted flats, maisonettes and ex-warehouse conversions (Angel, Clerkenwell, City Road Basin): A large share of Islington's housing is converted flats. Flats and maisonettes get no permitted development rights at all, regardless of location. Any external change needs full planning permission, and freeholder or lease consent usually needs checking too.

Common Problems We See in Islington Properties

Islington's period housing has a predictable set of issues, and knowing them before we start a job saves time and avoids nasty surprises once walls are opened up.

• Damp from failed damp-proof courses: Most Victorian terraces here have an original slate or bituminous-felt DPC over a century old. Bridged ground levels, cracked pointing and failed guttering let water in, and modern cement renders or vinyl wallpaper trap it, rather than letting the wall breathe the way it was designed to.
• Seasonal cracking from London clay: Shallow Victorian foundations sit on reactive clay that expands and contracts with the seasons, producing a pattern of hairline cracks in more or less every Islington terrace. Most of it is historic and expected, but it needs a trained eye to tell that apart from active movement.
• Drainage blockages from tree root ingress: Islington's tree-lined streets mean old clay pipe joints are a common entry point for roots, especially from London plane and lime trees, one of the most frequent causes of recurring blockages we deal with in this part of London.
• Hidden structural surprises behind chimney breasts and outriggers: Partial chimney-breast removals from decades past are common in Islington terraces, and the support above isn't always what it should be, something we always check before opening a wall.

Where We Work in Islington

We cover the whole borough, N1, N1C, N5, N7, N19, and the Islington pockets of EC1 (EC1A, EC1N, EC1R, EC1V), including:

• Angel & Upper Street: the antiques stalls of Camden Passage, the Business Design Centre, and the Georgian and Victorian shopfront conversions along Upper Street and Essex Road.
• Barnsbury & Canonbury: Georgian squares around Myddelton Square and Canonbury Square, close to Highbury & Islington station.
• Highbury: the Victorian terraces around Highbury Fields and Highbury New Park, near Union Chapel on Compton Terrace.
• Holloway, Archway & Tufnell Park: Victorian terraces along Holloway Road, near the Emirates Stadium and Caledonian Park.
• Finsbury Park: Victorian terraces bordering the park itself, near Finsbury Park station.
• Clerkenwell & Finsbury: the mixed residential and warehouse-conversion streets around Exmouth Market and Clerkenwell Green.

Working Around Islington's Parking and Access

Islington is covered entirely by Controlled Parking Zones, and on Arsenal home match days at the Emirates Stadium, restrictions near Highbury and Holloway extend beyond the normal CPZ hours. We arrange our own tradesperson parking permits and any skip or builder's bag permits needed for public highway placement before work starts, so deliveries and scaffolding don't hold your project up on day one.
