How long does a typical home extension take?

Most single-story extensions take 8-12 weeks from start to completion, depending on size and complexity. We provide detailed timelines during our initial consultation.

Do I need planning permission for a home extension?

Many extensions fall under permitted development rights, but this depends on your property type and extension size. We help assess requirements and handle planning applications when needed.

Are you fully licensed and insured?

Yes, we are fully licensed with £2 million public liability insurance. All our tradespeople are qualified professionals and members of relevant trade associations.

Prime London's Trusted Luxury Builder

Vine Construction luxury London home renovation — Kensington townhouse extension with heritage sash windows and stone facade

Vine Construction is a family-run firm of luxury London builders specialising in the discreet, high-specification renovation of period townhouses, mews properties and prime residential estates across the capital. Since 2008 we have delivered complex home extensions, loft conversions, basement conversions and full period property restorations for owners of Grade II listed homes, conservation-area properties and estate-managed leaseholds including Grosvenor, Cadogan, Portman and Howard de Walden.

Our teams combine traditional trades — lime plastering, timber joinery, lead work, stone masonry and traditional sash window restoration — with modern building science: airtightness detailing, MVHR, underfloor heating and heritage-appropriate secondary glazing for acoustic and thermal upgrades that preserve historic character. Every project is led by a dedicated contracts manager, delivered under a JCT contract, and covered by £2m public liability and £10m employer's liability insurance.

Commercial · Offices, Retail & Hospitality

Commercial Interior Decoration in London

Commercial decoration is judged on two things: how the space looks the morning it re-opens, and how invisible we were while getting it there. Our commercial team delivers office, retail, hospitality and clinical interior decoration across central London — from Mayfair private offices and Bond Street retail units to Marylebone medical clinics and Chelsea restaurants — working evenings, weekends and phased shutdowns so trading is uninterrupted.

We hold public liability cover to £5m, all operatives are DBS-checked where clients require it, and we work to method statements, risk assessments and site-specific inductions on every project. For landlords and managing agents we can operate to full permit-to-work systems, out-of-hours dust and fume control, and post-completion certification.

The finish standard is residential-grade — the same preparation, the same premium coatings, the same senior decorators — because a Mayfair office reception is judged by the same visitors who set the bar in their own homes.

Offices & Corporate Interiors

For office and corporate interior decoration we work to the tight programmes that go with lease turnovers, dilapidations settlements and pre-launch fit-outs. Typical scope includes full-height wall preparation, feature-wall branding, meeting-room accents, ceiling reinstatement after M&E works, and durable finishes on high-touch zones such as reception desks and lift lobbies.

Where the client is remaining in occupation we run evening and overnight programmes, using low-VOC coatings that allow the space to be back in use by 8am without odour or air-quality complaints.

Retail & Hospitality Environments

Retail interiors demand a finish that photographs well and stands up to daily footfall. We specify hard-wearing eggshell and satin coatings on walls, two-pack polyurethane finishes on joinery, and specialist textured or metallic effects for feature areas. In hospitality — restaurants, bars, private members' clubs — we manage decoration around live kitchens and licensed hours, with fast turnaround so the venue trades the same week.

Clinics, Consulting Rooms & Regulated Spaces

For clinical and consulting environments we work to CQC-appropriate specifications: wipe-clean, antimicrobial or scrubbable coatings, coved skirting where required, and finishes that meet infection-control expectations. Programme sensitivity is critical — clinic downtime is expensive — so we prefer phased room-by-room decoration during evenings and weekends.

Managed Programmes for Multi-Site Clients

For estate managers and multi-site retailers we manage rolling redecoration programmes across a portfolio — Bond Street, Sloane Street, Regent Street and beyond — with consistent quality standards, dedicated account management, and monthly reporting. This is often more cost-effective than piecemeal contractor selection and gives you a single point of accountability.

Frequently Asked Questions

Can you work outside our trading hours?

Yes. The majority of our commercial work runs evenings, weekends and overnight to minimise trading impact. All operatives are supervised and building sign-in / access protocols followed.

What insurance and compliance do you hold?

£5m public liability, £10m employers' liability, CHAS accreditation, and DBS-checked operatives available. Method statements and risk assessments provided for every project.

Can you match our brand colours exactly?

Yes. We hand-match to any Pantone or hex reference using spectrophotometer-verified samples, then supply the paint from Little Greene, Dulux Trade or the client's preferred manufacturer.

Do you handle wallpaper and specialist finishes for retail?

Yes — vinyl wallcoverings, digital murals, metallic and lime-based finishes are regularly specified for hospitality and retail interiors. See our wallpaper hanging service for detail.
