Annexe / outbuilding in Rotherhithe
Rotherhithe is London Borough of Southwark's georgian (1790-1830) thames-frontage warehouse-conversion stock submarket. Rotherhithe Village's Thames-frontage warehouse stock includes several Grade II listed buildings (Brunel Museum area, Hope Sufferance Wharf), and any internal works to the listed warehouses need LBC through Southwark conservation, with the conservation officer particularly strict on retained timber-and-cast-iron structural fabric.

Rotherhithe Village's Thames-frontage warehouse stock includes several Grade II listed buildings (Brunel Museum area, Hope Sufferance Wharf), and any internal works to the listed warehouses need LBC through Southwark conservation, with the conservation officer particularly strict on retained timber-and-cast-iron structural fabric.
Most of Rotherhithe's Thames-frontage sits in Environment Agency Flood Zone 3a, which means basement schemes here need a flood risk assessment plus a sequential test under NPPF Annex 3, adding 6-8 weeks to consent.
The Port of London Authority is a statutory consultee for any works that affect the Thames foreshore or river wall, and any below-ground works within 16m of the river wall need a PLA Section 73 licence in addition to Southwark planning.

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.
