Luxury Builders
in Greenwich & Blackheath

Prime residential construction in Greenwich & Blackheath

Crown Building works at the top of the London market, and Greenwich & Blackheath is core territory for our team. The projects in our published case studies were delivered under exactly the constraints that define this part of London. Protected fabric, exacting consents, discreet site conduct and clients who judge the result at touching distance.

We do not operate at volume. We compete on execution. Meticulous programming, a trusted specialist supply chain and senior management present on site throughout are the baseline for every commission we accept in Greenwich & Blackheath. The standard does not change with the scale of the project.

What we build in Greenwich & Blackheath

Our residential work spans the full scope of high end building. We deliver architecturally distinctive new build homes, private residence refurbishments and structural reconfigurations, single and multistorey extensions, basement excavations, listed and period property works, and the bespoke joinery and interiors that define a finished home. Each project is delivered as design and build or contractor only, with Crown appointed as your prime residential main contractor, and transparent, itemised pricing from the outset. Commercial occupiers are served by the same teams through our commercial fit out division, and clinical and wellness premises through our healthcare and specialist environments team.

Blackheath's Georgian and Regency terraces: the Paragon, Montpelier Row, Dartmouth Grove, and the Cator estate's substantial villas are heritage assets first and family homes second, and the work must respect that order: listed consents, correct materials, craft trades. Greenwich's West Greenwich conservation area and the streets around the Park bring World Heritage Site sensitivities into planning. Beneath the heritage layer, these are houses being brought up to modern family specification, kitchens, services, insulation, garden rooms, and the join between old and new is where quality shows.

Areas we serve

We work across Greenwich and Blackheath: the Paragon, Montpelier Row, the Cator estate, West Greenwich and Greenwich Park's borders. Plus Charlton and Lee. You can see our full coverage, London within the M25 and a fifteen mile radius of our Watford headquarters, on our areas we cover page.

The heath is split by the A2, and so is the planning regime

Blackheath sits across a borough boundary, and the line is the A2 Shooters Hill Road. North of it is Royal Greenwich; south of it, including Blackheath station and the village, is Lewisham. Each borough designates its own separate Blackheath conservation area, and Greenwich additionally has Blackheath Park. Establishing which side an address falls on is the first question on any project here.

The two basement regimes are quite different. Greenwich has no standalone basement policy in its Core Strategy, which addresses extensions including basements only through a general design policy. The numbers sit in its Urban Design Guide, which supports only single storey basements, generally limits them to the host building footprint, may refuse schemes where daylight provision causes cumulative loss of more than half the rear or front garden, does not support basements at listed buildings and does not permit them in Flood Zone 3, with a Basement Impact Assessment required. Lewisham adopted a new Local Plan on 16 July 2025, and its Policy QD9 requires a Basement Impact Assessment proportionate to the host building, accounting for local geology, showing no harm to trees of value and maintaining adequate soil depth for landscaping. It sets no numeric limits at all, so no garden percentage, storey cap or soil depth figure should be quoted for a Lewisham address.

Maritime Greenwich is a World Heritage Site, and the buffer reaches the heath

Greenwich carries a constraint that few English boroughs do. Maritime Greenwich was inscribed as a UNESCO World Heritage Site in 1997, with a Statement of Outstanding Universal Value agreed in July 2013. Policy DH4 requires that development within the site, its buffer zone and its setting must not harm that value, expressly including views to and from the site.

The geography matters for building work. Greenwich Park and the heath north of the A2 sit inside the World Heritage Site itself. The heath south of the A2 and Blackheath Village sit within the buffer zone. A property well away from the Old Royal Naval College can therefore still be assessed against World Heritage policy, and the buffer zone is treated as inappropriate for tall buildings. There is also a formal Blackheath Joint Working Party, a joint Greenwich and Lewisham body coordinating planning and management across the heath, with the Blackheath, Greenwich and Westcombe Societies represented.

Article 4 coverage differs sharply between the two boroughs

On the Greenwich side, householder Article 4 directions cover Ashburnham Triangle, East Greenwich, the Progress Estate, Rectory Field, Shrewsbury Park and West Greenwich, but notably not the Blackheath or Greenwich Park conservation areas. Greenwich has twenty three conservation areas and almost a thousand listed buildings.

On the Lewisham side the position is the opposite way round: historic environment Article 4 directions cover around thirty five conservation areas including Blackheath, alongside a borough wide direction covering small houses in multiple occupation. Lewisham has twenty nine conservation areas and over six hundred listed buildings. Two adjacent properties either side of the A2 can therefore sit under materially different control, which is exactly the kind of thing that needs checking rather than assuming.
