Rear & side extensions in Fulham
Fulham is London Borough of Hammersmith and Fulham's victorian + edwardian terraces (1880-1910) — 'fulham pattern' cottages + peterborough estate submarket. The Peterborough Estate (built 1895-1905) has unusually narrow plot widths (3.7-4.2m) with set-back front gardens and distinctive white-brick façades — any extension that changes the repeating rhythm requires an H&F Design Review, adding 4-8 weeks.
What a rear & side extensions project looks like here
The Peterborough Estate (built 1895-1905) has unusually narrow plot widths (3.7-4.2m) with set-back front gardens and distinctive white-brick façades — any extension that changes the repeating rhythm requires an H&F Design Review, adding 4-8 weeks.
H&F's Basement Policy (adopted 2015) is among the strictest in London — the council refuses any multi-storey subterranean excavation and requires a Basement Impact Assessment on any single-storey dig greater than 1.2m deep.
Because Fulham has a high density of two-up-two-down Victorian cottages on 3.7-4.2m plot widths, almost every kitchen remodel here involves a rear return / side return extension to gain a family-dining space — this has driven a specific Fulham-side-return design typology with known cost bands.

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.
