For a flat in Knightsbridge, read the lease and identify the landlord or managing agent before agreeing alterations.

International luxury quarter between Hyde Park and South Kensington. Mix of grand period buildings and modern luxury developments. Split between Westminster and RBKC. A refurbishment in Knightsbridge coordinates the layout, mechanical and electrical services and finishes with the condition of the building. The agreed scope determines what is retained, repaired or replaced, including the treatment of original period features.
Our Knightsbridge refurbishment projects are managed through a single point of contact, coordinating architects, structural engineers, M&E specialists, and specialist subcontractors. We work within Westminster's planning and building control requirements against the agreed scope and programme.
Flat refurbishment in Knightsbridge: what actually drives the project
Knightsbridge combines Regency and Victorian townhouses with prime mansion flats around Lowndes Square, Cadogan Place and Wilton Place, where many buildings are listed, leasehold or estate-controlled.
Knightsbridge sits within RBKC conservation areas, where external change and basements are tightly controlled. Estate or freeholder consent and Licence to Alter requirements often run alongside planning and Building Regulations.
Cost is driven by high specification, RBKC-compliant basement works, acoustic separation in mansion blocks, conservation-grade external work and party-wall awards with close, high-value neighbours.

What a Flat Refurbishment Involves
Refurbishing a flat means renovating inside a building you share — so the job is as much about leases, neighbours and building rules as it is about kitchens and finishes. We plan every project around the consents your lease demands and the protocols your block expects, then deliver the technical work under one fixed-price contract. A typical scope covers the elements below.
- Licence to Alter — lease review, application pack and freeholder’s surveyor queries handled on your behalf
- Acoustic build-up — separating floors and walls upgraded to meet Building Regulations Part E and any stricter freeholder schedule
- Wet-room tanking — certified waterproofing beneath every bathroom, flood-tested before tiling and covered by a 12-month defects period
- Rewire & replumb — new circuits, pipework and heating, coordinated with the building’s risers and stacks
- Layout changes — internal openings engineered, approved by building control and cleared with the freeholder where the lease allows
- Kitchens & bathrooms — designed, supplied and fitted to the specification tier you select
- Period detail — cornicing, sash windows and fireplaces retained and repaired in conversion flats
- Block protocols — lift protection, booked deliveries, restricted noisy hours and daily cleaning of communal areas
How We Run Your Project
Six stages, with the consent requirements and their effect on the programme considered before work starts.
- Survey & lease review — we measure the flat, inspect the services and read your lease to identify exactly which consents apply.
- Design & consents — our architects develop the layout while the Licence to Alter application runs in parallel, not afterwards.
- Fixed-price contract — an itemised specification agreed in full, with the acoustic and tanking details written in.
- Strip-out & first fix — soft strip, structural openings, cabling, pipework and the acoustic carcass, all removed and delivered through agreed routes.
- Second fix & finishes — kitchen, bathrooms, joinery, flooring and decoration.
- Testing & handover — snagging, certification and reinstatement of any communal areas before the keys come back to you.
Read the full flat refurbishment guide for flat typologies, specification tiers and the Licence to Alter process in detail.
Read the lease and identify any required freeholder consent or Licence to Alter for the proposed work before it is programmed. Planning permission, listed-building consent and Building Regulations are separate checks. Flats do not share the householder permitted-development rights available to houses, but that does not mean every external repair needs an application: like-for-like window replacement may not need planning permission, subject to the property and local requirements. Check the actual alteration, including any effect on a listed building's special interest. Our planning guide library explains the separate approval routes.
Why Hampstead Renovations
Flat refurbishment rewards a team that already knows what freeholders and managing agents will ask for. Design is led by our in-house RIBA Chartered Architects, lease and party-structure matters are supported by RICS surveying through our sister company, Hampstead Chartered Surveyors, and the build is carried out by our own long-standing teams. Every contract is fixed-price on JCT terms, backed by £10M public liability insurance — the level major London freeholders require — plus a 12-month defects period. Enquire before 2pm on a weekday and we will call you back the same day.

Flat Refurbishment in Knightsbridge: Questions
Do I need a Licence to Alter to refurbish a flat in Knightsbridge?
For a flat in Knightsbridge, read the lease and identify the landlord or managing agent before agreeing alterations. Written consent or a Licence to Alter is required where the lease and proposed work call for it; do not assume the same requirements for every building. Check shared floors, walls, service routes and access conditions. Planning and listed-building requirements are separate checks with Westminster or Kensington and Chelsea.
What kinds of Knightsbridge flats do you refurbish?
The great mansion blocks hold some of the most valuable leasehold flats in London, set among the grand stuccoed and red-brick terraces of Lowndes Square and Cadogan Place and the elegant houses of Wilton Place and Montpelier Square. In the blocks, structure, acoustics and freeholder or estate consents are handled as one exercise — the finish is exacting, and so is everything behind it.
Which planning rules apply to a flat refurbishment in Knightsbridge?
Check the address and proposed work with Westminster or Kensington and Chelsea. Confirm the conservation-area boundary, any Article 4 direction and whether the building is listed. Listed-building consent may be required for alterations affecting its special interest, including internal work. An Article 4 direction applies to specified properties and types of development; it does not make every refurbishment a planning application. Assess Building Regulations and any lease or estate consent separately.

Local character & heritage: renovating flats in Knightsbridge
Knightsbridge sits in the City of Westminster and the Royal Borough of Kensington & Chelsea, and a large share of its homes are leasehold flats — within grand stucco and red-brick mansion flats and townhouses. Refurbishing one is a full interior project: reconfiguring the layout, renewing services and finishes, and often combining or reworking rooms within the existing footprint.
The work runs under the lease, so the freeholder's or managing agent's consent sits alongside Building Regulations and party-wall notices may be needed for qualifying work; external elements such as windows stay controlled in conservation areas. Because most homes are high-value leasehold flats and a large share are listed, we coordinate the lease, the freeholder and the build as one fixed-price contract.

the Royal Borough of Kensington & Chelsea context
Check the address and proposed work with Westminster or Kensington and Chelsea. Confirm the conservation-area boundary, any Article 4 direction and whether the building is listed.
