Building and renovation in N1
N1 covers Islington, Angel, Barnsbury, Canonbury, De Beauvoir, Hoxton. Georgian terraces in Barnsbury and Canonbury, Victorian houses in De Beauvoir, canal-side warehouse conversions and a large stock of conversion flats.
Planning and consent in N1
Islington and Hackney conservation areas cover most of the district, with widespread listing on the Georgian squares. Islington's basement policy restricts depth and garden footprint, and rear extension design is closely controlled.
Access and site logistics
Narrow streets with heavy permit parking, canal-side access limits and almost no rear access. Grab collections and small scheduled deliveries are standard, with protected routes through the house.
What we are usually asked for here
- Georgian townhouse renovation and restoration
- Lower-ground-floor and cellar conversion with light wells
- Rear extensions and closet-wing infills
- Conversion-flat renovation with acoustic and fire upgrades
We survey the property before pricing, confirm the constraints that apply to your specific address rather than the postcode, and issue a fixed price against a written scope. One site manager runs the trades from first fix to snagging.

Islington and Hoxton have Georgian and early-Victorian terraces with vaults under the front pavement and cellars converted to kitchens, utilities and studies, often within conservation areas.
Vaults are usually kept breathable and ventilated rather than sealed. Inside the house we install cavity drain membrane, a channel to a discreet sump under a cupboard, and a floor membrane before insulation and screed, keeping historic brick intact behind the system.
A Type C cavity drain system in N1 is specified after a survey, designed to BS 8102 for the way you intend to use the room, and installed with the drainage channel, sump and pumps left accessible for maintenance. Read the full basement waterproofing and Type C cavity drain guide, or see how it fits into a basement and cellar conversion.
Waterproofing or damp proofing in N1?
Damp proofing deals with moisture in above-ground walls. Waterproofing protects a room that sits below ground against water pressure from outside. In Islington & Hoxton we decide which one the property needs at the survey, and often the answer is an external repair first.
How a N1 quotation works
We visit, find the source of the water, check head height, drainage outfall and any lease or listed-building constraints on your address, then issue a written scope and fixed price covering membrane, channel, sump and pumps and the finished room.
Garden designer in N1
Islington and Hoxton terraces often have compact gardens suited to clear zoning, durable paving and screening planting.
North London gardens range from small terrace yards to steep hillside plots; level changes, access through the house and clay soil drainage are the usual starting points.
Our garden design and landscaping service covers layout, levels and drainage, planting, terraces and paths, garden lighting and external power, and how materials and plant reach the garden. In N1 that access question matters: Narrow streets with heavy permit parking, canal-side access limits and almost no rear access. Grab collections and small scheduled deliveries are standard, with protected routes through the house.

N1 roofs commonly include slate, parapets and butterfly or valley gutters hidden behind terrace facades.
Terrace roofs with butterfly or valley gutters, parapets and slate coverings are common, and rainwater outlets hidden behind parapets are worth checking first.
Roofing work starts with a survey and photographs, then a written scope that states whether repair or replacement is recommended: pitched and flat roofs, leadwork and flashings, guttering and rainwater goods, and the scaffolding the roof needs. Planning, conservation and freeholder requirements for your address are confirmed at survey.
