Luxury interior design in Marylebone
Marylebone is City of Westminster's georgian terraces (1770-1830) around portman and howard de walden estates + edwardian mansion blocks submarket. Around 60% of Marylebone freeholds are still held by the Howard de Walden Estate or the Portman Estate, so any significant works on an estate lease require Estate Licence to Alter plus Planning — two parallel consent tracks that typically run 12-16 weeks each but can be compressed when scheduled together.
What a luxury interior design project looks like here
Around 60% of Marylebone freeholds are still held by the Howard de Walden Estate or the Portman Estate, so any significant works on an estate lease require Estate Licence to Alter plus Planning — two parallel consent tracks that typically run 12-16 weeks each but can be compressed when scheduled together.
Because Georgian Marylebone terraces often have 4-5 habitable storeys above a shallow basement, the 2022 Building Safety Act higher-risk-buildings threshold (18m / 7 storeys) rarely bites — but cladding remediation still applies to post-1960 mansion-block inserts along Marylebone Road.
The Harley Street medical cluster means many Marylebone ground floors are mixed-use with surgeries or clinics; changing a ground-floor clinic back to residential use routes through a full Change of Use application rather than Class MA permitted development, adding 8-12 weeks.

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.
