Islington writes its Highbury rulebook street by street — literally. Within the Highbury Fields Conservation Area the council applies roof policies address by address: no roof extensions or dormers on most of Highbury Park, Highbury Terrace and Leigh Road, existing mansards on parts of Highbury Place and Highbury Terrace to remain unaltered, and traditional roof extensions permitted only on scheduled properties. In the Highbury New Park Conservation Area, no new or altered dormers are allowed on front or side roof slopes at all. A builder here checks the address against the policy before anything is drawn.
The stock deserves the care. Gathered around the green expanse of Highbury Fields, the conservation area takes in some of the finest Georgian terraces in the borough fronting the Fields, the Victorian villas between Highbury Hill and Aubert Park and the old village centre of Highbury Barn — with an Article 4 Direction over the lot. Highbury Place and Highbury Fields face the park, Aberdeen Park holds larger detached and semi-detached Victorian villas, and Highbury Grove mixes period houses with Edwardian mansion blocks.
The work follows the type: whole-house refurbishment, lofts and rear extensions on the terraces and villas, leasehold projects in the mansion flats where acoustic separation and freeholder consents sit alongside the finish. The headline range for a house renovation in Islington is £90,000–£475,000 excluding VAT.
Builders in Highbury: Applied to the Local Stock
Highbury sits in the London Borough of Islington, gathered around the green expanse of Highbury Fields. The Highbury Fields Conservation Area (CA5) takes in some of the finest Georgian terraces in the borough fronting Highbury Fields and the distinguished Victorian villas north of the Fields from Highbury Hill to Aubert Park, together with the old village centre of Highbury Barn; an Article 4 Direction applies to the conservation area. Islington's register also designates Highbury New Park (CA15) and Aberdeen Park (CA27) as conservation areas; Highbury New Park was laid out in the 1850s as a fashionable development of grand detached and semi-detached houses, and no new or altered dormer windows are allowed on front or side roof slopes of properties in that area.
Within the Highbury Fields Conservation Area the council applies street-by-street roof policies: no roof extensions or dormers are permitted on most of Highbury Park, Highbury Terrace and Leigh Road, existing mansards on parts of Highbury Place and Highbury Terrace must remain unaltered, and traditional roof extensions may be permitted only on scheduled properties.

What Our Building Service Covers
Hiring a builder should mean hiring one accountable team, not refereeing a chain of subcontractors. As a design-and-build practice we carry your project from drawings to handover under a single fixed-price contract, with the architect, engineer and site manager answerable to the same programme. The scope below covers most of the building work we are asked to price.
- Extensions — rear, side-return and wraparound additions, built weathertight before the existing house is opened up
- Loft & basement conversions — new storeys above and below, with steelwork and waterproofing engineered in-house
- Structural alterations — load-bearing wall removals, new openings and floor changes with calculations done before pricing
- Refurbishment — whole-house or single-floor upgrades sequenced so trades never queue behind each other
- Kitchens & bathrooms — first fix to final silicone, delivered by the same teams who built the rooms around them
- Mechanical & electrical — rewires, heating systems and ventilation installed and certified as part of the main contract
- Joinery & carpentry — doors, staircases, skirting and fitted furniture made to suit the age of the building
- External & facade works — brickwork, render, roofing repairs and landscaping tied into the main programme
How We Run Your Project
Six checkpoints between first phone call and final handover, each signed off before the next starts.
- Site visit & scope — we walk the property with you, test what the budget can realistically deliver and flag constraints early.
- Drawings & approvals — our architects prepare the design and handle whatever consents the work requires.
- Itemised fixed price — every trade, material and provisional sum listed line by line, so nothing is priced twice.
- Mobilisation — protection, welfare, neighbour notifications and deliveries organised before the first skip arrives.
- The build — structural work, first fix, second fix and finishes run by a dedicated site manager you can reach directly.
- Handover — a walked snagging inspection, full certification pack and aftercare contact once the site is cleared.
Almost all building work of this scale needs Building Regulations approval — structural openings, electrics, drainage, heating and fire safety are each inspected and certified through building control, which we manage on your behalf. Where the works cut into, bear on or excavate near a wall shared with a neighbour, the Party Wall etc. Act 1996 obliges you to serve notice before starting, and we coordinate the surveyors so the programme is not held hostage to it. Our planning guide library sets out what applies borough by borough.
Why Hampstead Renovations
The word “builder” covers everything from a van and a ladder to a full construction practice, so credentials matter. Ours: design by our in-house RIBA Chartered Architects, structural calculations from our own chartered structural engineers, and RICS surveying support through our sister company, Hampstead Chartered Surveyors, for party wall and condition matters. Every project runs on a fixed-price JCT contract, carries £10M public liability insurance, and is backed by a 12-month defects period plus a 10-year workmanship warranty. Enquire before 2pm on a weekday and we will call you back the same day.
Builders in Highbury: Questions
Which conservation areas cover Highbury?
Islington designates three here: Highbury Fields (CA5), which takes in the finest Georgian terraces fronting Highbury Fields, the Victorian villas from Highbury Hill to Aubert Park and the village centre at Highbury Barn, plus Highbury New Park (CA15) — laid out in the 1850s as a development of grand detached and semi-detached houses — and Aberdeen Park (CA27). An Article 4 Direction applies to the Highbury Fields Conservation Area.
Are there Highbury streets where roof alterations are restricted?
Yes — the council's policies are street-specific. Within the Highbury Fields Conservation Area, no roof extensions or dormers are permitted on most of Highbury Park, Highbury Terrace and Leigh Road; existing mansards on parts of Highbury Place and Highbury Terrace must remain unaltered; and traditional roof extensions may be permitted only on scheduled properties. In Highbury New Park, no new or altered dormers are allowed on front or side roof slopes.
What building work suits Highbury's houses?
The terraces and villas suit whole-house refurbishment, loft conversions and rear extensions, with conservation-led restoration of brick, stucco and joinery on the period houses — while the Edwardian mansion flats of Highbury Grove are leasehold projects where acoustic separation and freeholder consents sit alongside the finish.
What does a house renovation cost in Highbury?
The headline range we use in Islington is £90,000–£475,000 excluding VAT. Within that, London-wide bands put a cosmetic renovation of a three-to-four-bed terrace at £90,000–£180,000 and a back-to-brick renovation at £275,000–£475,000, both excluding VAT.
What should we expect Islington's planners to focus on in Highbury?
The council is demanding on terraces of group value, windows and rear extensions, and the mansion blocks add a leasehold layer on top. On the cost side, budgets are driven by terrace structure, party-wall awards, facade and window decisions, leasehold approvals in flats, acoustic upgrades, service renewal and the access limits of established N5 streets.
How do you differ from a standalone builder in Highbury N5?
Most builders subcontract design, structural engineering and planning — leaving you managing four to six separate firms with overlapping responsibilities and gaps where things get dropped. We are one practice with every discipline in-house: RIBA chartered architects, surveying support through Hampstead Chartered Surveyors, IStructE chartered engineers and our own build teams. That means one contract, one point of responsibility, one fixed price.
