Projects / Heathrow Terminal Four Extension


Heathrow Airport Limited

Project description

We were Architect and Lead Designers on BAA’s ‘Tomorrow’s T4’, a suite of projects which transformed Heathrow’s Terminal 4. The project was delivered from inception to completion over a 30 month period within the £180 million budget. New projects included a 7750m2 departures concourse extension, departures forecourt and public realm plaza and 1400m2 CIP lounge accommodation. Full refurbishment projects included the existing departures concourse, central search area, transfers security area, airside arrivals concourse and the immigration hall. The departures extension features a bespoke glazed façade designed to withstand the strictest bomb blast criteria and together with a 180m long ETFE canopy forms a grand gateway into the terminal. All projects developed and integrated the Heathrow character and product palettes initially defined at T5 to introduce a ‘Heathrow brand’ look and feel across the terminal. Palette materials included floor, wall and ceiling finishes, way finding, architectural metalwork process desks and other specialist joinery. Also key to the design was ensuring the access and maintenance strategies employed were aligned with the holistic airport wide initiatives.

Innovations & added value

We sourced our own manufacturers and supply chain and modelled full size mock ups of the glazing panels, designing new products that gave a much closer fit and minimised warping. This gave not only much better quality of finish, but also greater control over the quality of the components. This also benefitted the project with a rapid construction programme.
