Structural stabilisation in Chelsea

Chelsea is Royal Borough of Kensington and Chelsea (RBKC)'s early georgian (1720-1780) submarket. Chelsea's Cadogan Estate freehold covers roughly 93 acres — a quirk that means many kitchen remodels here require a secondary Estate Consent on top of RBKC planning, and the Estate's design review is consistently stricter on elevational changes than the council itself.

What a structural stabilisation project looks like here

Chelsea's Cadogan Estate freehold covers roughly 93 acres — a quirk that means many kitchen remodels here require a secondary Estate Consent on top of RBKC planning, and the Estate's design review is consistently stricter on elevational changes than the council itself.

Because RBKC's Basement Policy CL7 was tightened in 2015 to ban multi-storey subterranean excavations, any Chelsea scheme that includes a swimming pool or cinema now routes through a planning committee rather than delegated officer decision — add roughly 14 additional calendar weeks.

The area's pre-1850 long-narrow lightwell basements almost always have shallow brick footings at ~1.1m depth, so rear extension designs that sit within 3m of the neighbour wall trigger Party Wall Act underpinning notices on both flanks.

London is non-seismic — but London Clay shrink-swell + 19th-century shallow-footing terraces drive underpinning, helical pile, and crack-stitch retrofit work, all Building Regs Part A structural. In Chelsea specifically, early georgian (1720-1780) stock means structural stabilisation scope is shaped by the neighborhood's dominant construction typology.

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
