Healthcare investment company, 10M Healthcare, has successfully let No 1 Harley Street from The Howard de Walden Estate. The deal marks a significant investment in the future of outpatient care within London’s renowned Harley Street Health District.
The site will be transformed into a new £100m ambulatory surgery centre (ASC), due to open in Q4 2026. It will offer private patients high-quality same-day surgical treatments across a range of specialities including orthopaedics, neurology, gynaecology and women’s health, cardiology, dermatology, and ENT.
Situated in the heart of Harley Street Health District and designed around the needs of modern patients, No 1 Harley Street will have five surgical theatres providing same-day surgical treatments for minor procedures. It will also have GP consultation rooms, screening services, and wellbeing suites, bringing together multiple stages of the care pathway under one roof.



ASCs are specifically designed to provide high-quality day care for patients who do not require an overnight hospital stay, supporting improved patient outcomes and streamlined healthcare delivery. No 1 Harley Street will provide excellent care for private patients in the heart of London’s leading innovation district.
10M Healthcare is a specialist healthcare investment platform focused on developing and scaling high-quality clinical businesses across ambulatory care, diagnostics and digital health. Cushman & Wakefield represented 10M Healthcare throughout the negotiations.
Paul Bakker, Head of Healthcare Asset Management at The Howard de Walden Estate, landlord and steward of Harley Street Health District said:
“We are delighted to welcome 10M Healthcare to Harley Street Health District. This letting reflects the growing demand for high-quality ambulatory care and supports our broader ambition to create a more integrated, future-facing healthcare ecosystem in the heart of London.
“As part of our ongoing strategy, we are curating a diverse ecosystem that brings together leading providers, innovative care models and emerging technologies to support whole health from diagnosis through to recovery.”
Evi Georgadidis, Healthcare Capital Markets, Cushman & Wakefield, said:
“We identified No. 1 Harley Street as the right location for the new facility for several key reasons – its central position within London’s Harley Street Health District, its accessibility by public transport, and of course the prestige and credibility that come with a Harley Street address. We are incredibly proud to have advised 10M Healthcare on this deal.”
Ken Anderson, CEO at 10M Healthcare, said:
“Securing this building is a significant milestone and reflects our commitment to delivering a state‑of‑the‑art medical facility for short‑term day patients. What sets this development apart is the creation of a fully integrated ASC in the heart of the Harley Street Health District. The extensive refurbishment and fit‑out is well underway, and we look forward to opening later this year in London’s leading health innovation district.”
