House Refurbishment Marylebone

House refurbishment in Marylebone is the smaller part of the work. The VOA figures for the wider Marylebone & Park Lane and Bryanston & Dorset Square statistical areas put houses at 8% of homes, almost all of them terraced. The streets are known for mansion blocks and Georgian townhouses, and a house refurbishment renews a townhouse's wiring, pipework, plaster, joinery, sashes and roof without re-planning its rooms. On a Marylebone street, Westminster also controls the hours, the scaffold and the footway outside the front door.

For Marylebone, published UK figures put a three-bed house refurbishment at £43,530 to £110,350, and London houses usually cost more, with a London architect allowing £1,800 to £2,200 per square metre before VAT (Checkatrade and Bradley Van Der Straeten Architects, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Marylebone: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

What a Marylebone townhouse needs renewed after a century of use

In the VOA figures for the Marylebone & Park Lane and Bryanston & Dorset Square statistical areas, houses make up 8% of homes and almost all are terraced, and 54% of homes were built before 1919. So a townhouse refurbishment usually opens up lime plaster on lath, solid brick walls and floors laid on timber joists that have been cut for a century of cables and pipes. We strip back only what has failed and patch the rest in materials that behave like the original. Gypsum skims over lime can trap moisture, so the specification is agreed room by room before the first wall is touched.

A tall terrace brings its own list beyond the plaster. There is a long timber stair with worn treads and loose balusters, sash windows with rotten sills and broken cords, and a roof, parapet gutter and chimney stacks reached only by scaffold. We repair sashes where the frames are sound and renew them where they are not, and we coordinate roof and stack repairs as the survey requires so the scaffold goes up once. A stack shared with next door needs a party wall notice under the Party Wall etc. Act before it is repaired or rebuilt, and you serve that notice as the building owner. Where a floor, wall or roof element is renewed, insulation to Part L goes in at the same time.

Housing in Marylebone

Count the homes in Marylebone and you get about 12,620: 29% built since 1945, 16% between the wars and 54% before 1919, with flats at 92% and houses at 8%. Most homes here are flats, and where most homes in Marylebone are flats, a whole house is refurbished as one building, with a single intake for the services and one roof to keep sound.

Sashes, doors and roofs on a Marylebone house in a conservation area

Check the designation before any window, door or roof on a Marylebone house is changed. Westminster has 56 conservation areas covering over 76% of the City, and East Marylebone was designated a conservation area in 1982 and extended in 1990. In a conservation area you need planning permission for demolition and for some alterations that would not need it elsewhere. Westminster has also removed permitted development rights in eight conservation areas, where planning permission is required for the specified minor alterations. Your designer or agent confirms which applies to your street.

For a refurbishment the practical line is between repair and change. Easing and re-cording a sash, splicing in a new sill or re-slating a roof in matching slate keeps the house as it was. Swapping timber sashes for a different pattern, fitting a new front door design or changing roof coverings is where permission can come in. Check the statutory list as well, which includes around 11,000 buildings and structures in Westminster. For a house on it, consent can reach inside, to plaster, joinery and fireplaces. We price both routes at survey, so you can decide what to repair and what to renew before anything is ordered.

Hours, scaffold and skips outside a Marylebone house

Westminster sets the hours for noisy work on a Marylebone house: Monday to Friday 8am to 6pm and Saturday 8am to 1pm. Noisy work outside that window needs a Control of Pollution Act Section 61 application at least 28 days before it starts. On a townhouse the loud stages are stripping plaster, lifting floors, chasing for cables and breaking out old hearths, and we keep all of them inside those hours so the neighbours on both party walls know when to expect them.

The front of the house is the only way in, so the pavement plan matters. Scaffolding, construction fencing or a cherry picker on the road or footway needs a temporary structure licence from Westminster, and the footway must not be reduced to less than 1.5m wide around works. A skip on the road needs its own permit from the highway authority, and on a narrow Marylebone street a wait-and-load collection or bagged waste can suit better. We settle deliveries, waste and any licence before the start date.

Phasing and sign-off for a Marylebone house refurbishment

An empty house is refurbished floor by floor in one pass: strip out, first fix of wiring and pipes, plaster, second fix, then decoration. If you are living in a Marylebone townhouse during the work, we split it into zones instead, often the upper floors first while you keep the ground floor and a working kitchen, then swap. That takes longer, but the heating, water and a safe stair stay in use throughout. The order is fixed before the start so the services run up the house only once.

Westminster building control has its own paperwork for a house. A building notice can be used only where the work does not affect the layout of the building and is not affected by the Fire Safety Order, which suits a like-for-like refurbishment of a single Marylebone house. Westminster must be told the start date at least 2 days before work begins. It issues a completion certificate only once all fees are paid and all relevant electrical and gas certificates have been supplied, so we collect those from the registered electrician and the Gas Safe engineer as each trade finishes.

• Whole-house replumbing, including old lead and galvanised supply pipes
• Staircase repairs: treads, risers, strings, balusters and newel posts
• Whole-house refurbishments for landlords re-letting a house

The GS Renovation Difference in Marylebone

You get one contractor for the strip out, repairs, services, plastering, joinery and decoration of the whole house, with the trades ordered so each floor is opened up once and closed once. We agree with you whether the house is phased around you or worked on empty, keep noisy stages inside the permitted hours, and arrange any pavement licence before we start. Certificates from the registered electrician and the Gas Safe engineer are gathered as each trade finishes, ready for the completion certificate and any later sale.

• A written scope and programme agreed before work starts
• First fix cabling on each floor inspected by the electrician before the walls are closed
• A top-floor-first programme when your family stays in the house
