Active project dates: approximately 1989-1992.

Chiswick Park is a business park located within an existing built-up area on a brownfield industrial site of the former Chiswick Bus Garage. In 1988 Stanhope Plc and Trafalgar House Plc formed a joint venture to develop this site, forming Stanhope Trafalgar Chiswick Ltd. In 1990–1991, architects Terry Farrell & Partners designed a masterplan on behalf of the consortium for the site with buildings designed by Foster Associates and Peter Foggo around the main piazza, and others by Rogers Stirk Harbour + Partners and ABK Architects around a smaller square to one side. Outline planning permission was granted in 1991 for 11 buildings to be constructed.

In 1996, Kværner took ownership of the site, selling it in 1999 to the Chiswick Park Unit Trust led by Schroders and Aberdeen Property Investors with Stanhope Plc as development manager. At this point Rogers Stirk Harbour + Partners were commissioned to prepare a new master plan.

The original Farrell design was an attempt to avoid the "A4 Death Valley syndrome," where office building as real estate investment was isolated along a transport artery. Instead, the masterplan was developed in dialogue with local residents and businesses, aiming to provide benefits to people both working and living at or near Chiswick Park. Planned facilities included a sports club, child day care centre, a running track and events area.
