Annexe / outbuilding in West Kensington
West Kensington is London Borough of Hammersmith and Fulham's high victorian (1870-1890) italianate stucco terraces submarket. The Barons Court Conservation Area covers most of Castletown Road, Edith Villas, and North End Road; the LBHF 2014 Article 4 Direction here strips Permitted Development for rear extensions, dormers, and replacement windows, and the conservation officer is unusually strict on stucco repair specifications.

The Barons Court Conservation Area covers most of Castletown Road, Edith Villas, and North End Road; the LBHF 2014 Article 4 Direction here strips Permitted Development for rear extensions, dormers, and replacement windows, and the conservation officer is unusually strict on stucco repair specifications.
The 2010s Earl's Court Opportunity Area Planning Framework places the southern half of West Kensington inside the OAPF zone, which requires a 35% affordable housing target plus Whole Life Carbon assessment under the Mayor's London Plan 2021 for any scheme above 10 units.
Many of the late-Victorian Italianate stucco terraces along Edith Villas are Grade II listed individually rather than as a group, so internal alterations including kitchen reconfigurations need Listed Building Consent in addition to LBHF planning, adding roughly 6-12 weeks.
Garden annexes, ancillary outbuildings and granny annexes — Permitted Development under Class E where the borough hasn't issued an Article 4 Direction; planning consent otherwise.

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.
