Lothbury Investment Management will next month launch a £100m fund targeting central London property next month.
The closed-ended fund will have a seven-year lifespan and invest mainly in offices, retail and leisure assets.
The investment manager is targeting US investors to raise £100m of equity, which is expected to come from wealth managers, family offices and institutional investors.
Lothbury was launched in 2010 after an all-equity management buyout of KBC Asset Management (UK) from the KBC Group, led by chief executive Simon Radford.
The group now has more than £1bn assets under management, including core funds the Lothbury Property Trust and the European Property Fund.
The firm is also responsible for management of the Clarendon and Broadland Unit Trust.
