Architects and Engineers in Kensington
Local knowledge of Kensington's stucco terraces, mansion blocks, and basement policy, from first feasibility conversation through to a finished project.
Living and Building in Kensington
Kensington Square, laid out in 1685, was the first garden square built outside central London, and that same instinct, grand houses facing shared green space, still defines streets near the Palace today. The red-brick mansion blocks that followed a generation later, pitched at buyers who'd never considered a flat before, now sit under the same protection, in places a listing covers the entrance hall and stair of an entire block, not just the address you actually live at.
Diagram X is a London AEC (Architecture, Engineering, and Construction) consultancy with hands-on experience of exactly this housing stock, stucco terraces, mansion block conversions, and mews properties tucked behind the grander streets, bringing architecture and structural engineering together in-house from that first conversation through to a project that actually gets built.
Planning in Kensington
Kensington carries one of London's most developed basement policies: excavation is generally limited to a single storey below the lowest floor, unbuilt garden coverage is capped at around half, and a Basement Impact Assessment examines ground and water conditions specifically, since Counter's Creek, an old culverted watercourse, still shapes drainage and flood risk along the borough's western edge.
Mansion block flats bring their own complications, alterations often need freeholder consent on top of planning permission, and listed status can cover the building's facade and communal stairwell even when your own flat was renovated decades ago. We test what a lease and a listing will actually allow before a design goes anywhere near a planning application.
Refurbishing in Kensington
A refurbishment today is rarely about putting a Kensington property back the way it was. Building standards, insulation, and how people actually want to live have all moved on since most of these interiors were last touched, often decades ago, so a genuine refurbishment means bringing a home properly up to modern performance and modern living, not recreating a past version of itself.
Heritage features earn their place when they're genuinely worth keeping, an original cornice line, a period fireplace, and we're glad to retain them deliberately within a thoroughly modern, open-plan result. But that's a choice we make feature by feature, not an assumption that period character should dictate the whole design.
Construction in Kensington
Kensington's mews were built for horses and carriages, not modern deliveries, and that history still shapes how a build gets managed today, narrow turning widths, shared cobbled access, and neighbours who notice everything. We plan logistics around that reality from day one, rather than finding out the hard way once a lorry can't get round the corner.
Basement and structural work demands particular care here given the borough's ground conditions and its history of culverted watercourses, with Party Wall agreements and monitoring in place well before excavation starts. The result is a contemporary home delivered safely, with Kensington's grand terraces and mansion blocks still standing exactly as they should on the street outside.
