Because Holland Park mid-Victorian villas typically have their original internal wooden spiral service stairs, LBC strictly refuses removal or structural alteration of these historic vertical circulation routes — forcing kitchen-to-basement MEP routing into unusual back-of-house paths.
The park's Registered Historic Park designation extends setting checks ~200m into the neighbourhood — even unlisted Edwardian infill within that zone must justify any roof-level addition on setting-of-heritage-asset grounds.

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.
