Kensington & Chelsea
We design and coordinate residential projects in Holland Park’s grand villas and townhouses, working within RBKC planning, conservation, heritage and basement policy.

The short answer
Yes — most of Holland Park sits inside the Holland Park Conservation Area, administered by the Royal Borough of Kensington and Chelsea, which adopted the current Conservation Area Appraisal on 19 June 2017. Article 4 directions, the earliest from 1978 with further directions to 2012, restrict permitted-development rights on specific streets and property ranges, so confirm the exact designation for your address before commissioning drawings.

Holland Park is one of London’s most prestigious residential addresses, characterised by grand detached and semi-detached villas, substantial townhouses and generous gardens around the park itself. It lies within the Royal Borough of Kensington and Chelsea, so it shares the borough’s rigorous planning and conservation policies and its specific basement controls. Properties here are high-value, projects are often comprehensive, and expectations of design quality and finish are correspondingly high.
The work we see most in Holland Park is high-value whole-house refurbishment, basement and lower-ground projects that add space without altering the street scene, carefully designed rear extensions, and internal remodelling of grand villa interiors. As elsewhere in RBKC, basement feasibility must be tested against the borough’s policy, which limits depth and extent and requires supporting reports, and party wall processes are almost always engaged given the scale of below-ground work.
Holland Park proposals are assessed by RBKC against the borough’s local plan, conservation-area appraisals, basement policy and the listing of the building where applicable. We design to those exacting standards, coordinate the structural, waterproofing, heritage and party wall input these substantial projects require, and prepare the planning and building regulations drawings — while being clear that no planning outcome can be guaranteed.
Local analysis
Holland Park work is not just large-house refurbishment. It can involve detached and semi-detached villas, townhouses, mansion flats, mews houses, garden-facing apartments, listed buildings and high-management blocks around the park and Holland Park Avenue.
The address should be checked against RBKC Holland Park conservation material, Article 4 street records, listed status, garden and tree context, basement policy, estate or freeholder controls and previous planning decisions.
A Holland Park package may need to satisfy RBKC planning, conservation officers, listed-building reviewers, freeholders, managing agents, structural and basement consultants, building control, party wall surveyors and contractors.
Holland Park projects often turn on basement feasibility, waterproofing, vaults, trees, garden levels, retained facade or roof fabric, services routes, acoustic floors, fire separation, party walls and high-value common-part protection.
Tender and site information should deal with access, parking, delivery windows, neighbour protection, tree protection, scaffold strategy, services shutdowns, basement method statements and protection of retained villa fabric.
The most expensive Holland Park mistakes are usually sequencing mistakes, so we would order the early stages deliberately. A measured survey and address-level checks come first: whether the property sits within the Holland Park Conservation Area, whether one of the Article 4 directions made between 1978 and 2012 covers the street or property range, whether the building is listed, and what the lease, freeholder or tree and garden context adds. Those answers set the consent route before layouts are refined, because a front-elevation alteration caught by an Article 4 direction can need a full application that an unaffected property would not, and a listed villa brings heritage reviewers into the approval path alongside RBKC planning officers.
From there, be honest about programme. Pre-application advice is worth considering where basement depth or heritage impact is finely balanced, and a lawful development certificate can settle whether permitted-development rights survive at a particular address. A householder application carries a statutory target of around eight weeks once validated, but validation depends on a complete package: for basement and lower-ground work the borough's policy requires supporting reports, so structural and waterproofing input commissioned late is the usual cause of drift. Party wall procedures run in parallel and notices benefit from early service, while building-regulations drawings form a separate package best begun once the consent strategy is settled.
Local services
Holland Park advice should establish whether the useful service is feasibility, heritage evidence, basement coordination, planning drawings, Licence to Alter, technical design or tender support.
High-value refurbishments should connect interiors to structure, services, fire, acoustics, waterproofing, common-part protection and contractor logistics early.

Is the property listed, estate-managed, leasehold, garden-facing or affected by trees, basement constraints or a sensitive roofscape?
