Covering Holloway

Homes in London

London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.

What goes into a wraparound extension?

Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.

Steel frame or goalpost for the corner opening
Pitched, flat or glazed roof with rooflights
Glazing, insulation, plastering and electrics

How is a wraparound extension approved in Holloway?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.

What should I think about before starting?

Roof water from an L-shape needs careful falls and outlets.
An open-plan space this size needs a heating plan, often underfloor heating.

What are the steps?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.

We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

What people ask before starting

Can we keep part of the kitchen working?

Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.

Glazed roof or solid roof?

A mix usually works best: solid roof with rooflights over the kitchen and a glazed section over the dining area.

Can you visit a house in Holloway to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
