The Perceval House site extends to approximately 1.27 ha (3.14 acres) and is located in the heart of Ealing town centre, within the London Borough of Ealing. The site backs onto the Great Western main line and is bordered to the east by Longfield Avenue and the south by Uxbridge Road and New Broadway.

The site is adjacent to the new Dickens Yard residential and retail quarter currently being developed by St George, due to complete in 2018. The site is also adjacent to the the Council-owned Grade II listed Ealing Town Hall, which is due to be refurbished and converted into a high quality boutique hotel. To the south of the site, Land Securities is developing a new cinema and mixed use scheme, to be known as Ealing Filmworks.

The site is currently dominated by Perceval House, a large office building constructed in the 1980s and occupied by the Council. There is also a car park to the rear of the site with approximately 106 spaces.

The Council owns the site freehold and is the main occupier apart from an area of the building leased to Ealing Clinical Commissioning Group (CCG). Scottish and Southern Energy (SSE) lease part of the site for a substation.

The building is arranged over five storeys and has a gross internal area (GIA) of approximately 212,000 sq ft (19,695 sq m) and is too large for the Council’s current operational requirements. It is anticipated that the building will require substantial investment in its mechanical and electrical equipment within the next 20 years.

The Council has taken the decision that a comprehensive redevelopment of the site is the best way to deliver a new HQ office building for its continued operation, customer service centre and a new library, as well as new private and affordable homes and other appropriate town centre uses.
