SEBASTIAN BORN

AGENT

Seb has spent over a decade immersed in the London property market, working across Sales, Lettings, New Homes and Commercial real estate. That breadth of experience across the full property spectrum is rare — it means Seb understands not just how deals are done, but how they interconnect, and how to move quickly when the right opportunity arises.

His reputation has been built the old-fashioned way: through repeat business, trusted referrals, and a genuine commitment to doing right by his clients. A significant portion of Seb's business is conducted off-market, operating with the discretion and confidentiality that serious buyers and sellers expect.

LONDON

Seb has worked all across the capital, and now calls Notting Hill home — a neighbourhood that reflects exactly the kind of character, architecture and community he champions for his clients. His knowledge of Prime Central London is granular and lived-in, not just transactional.

Outside of work, you’ll find Seb running through Hyde Park in the early mornings, or exploring the neighbourhood’s growing restaurant scene in the evenings.

PROPERTY

With over a decade of experience spanning the full breadth of London real estate, Seb has established himself as a trusted advisor to a distinguished client base including High Net Worth individuals, private family offices and overseas embassies.

He works extensively with international investors and buyers, with particular expertise serving clients from the Middle East, the United States and Asia. Seb travels to Asia regularly to maintain those relationships in person.

PEOPLE

For Seb, property has always been a people business first. His focus is on building lasting relationships — not just closing transactions — and being a consistent, dependable presence for his clients at every stage of the process.

Whether it’s an early-morning call from a client in a different time zone, a last-minute viewing request, or simply a second opinion on a decision, Seb makes himself available. His clients know they have someone genuinely in their corner — someone who will be there for the first deal and the tenth.
