The plans would see the Gurnell Leisure Centre in Ruislip Road East rebuilt along with private flats on the site, which would be used to help fund the community scheme.
Ealing Council is expected to use its new Broadway Living company which was set up develop homes in the borough for sale and both private and affordable rent.
Ealing’s cabinet agreed for officers to do preliminary work on possible options before reporting back in the autumn when decisions will be made about more detailed plans.
The revamped leisure centre would be designed to offer a 50m swimming pool, as well as a sports hall and gym.
