A brief history

GIA was established on 15th November 1993 at 6 Langley Street, Covent Garden. In the early days Gordon Ingram ran the business with the help of his mother Janet. They started operating on a small-scale with just two desks, a filing cabinet, and a computer.

The business grew quickly, moving next door, then to Drury Lane, and finally to The Whitehouse on the Southbank, where we are based today. Daylight & Sunlight specialists in a basement office with little natural light was always going to be a talking point. Gordon’s vision was to bring life and movement into the space and so he installed one of the largest fish tanks in London.

During the pandemic we completely transformed our office space. When we reopened in March 2022, our team returned to a fresh and cutting edge office environment that puts our team’s wellbeing and new ways of working at the forefront.

“GIA is a team who understand the built environment. They proactively assess the development opportunity and understand our aspiration in a visionary way”

“GIA’s market-leading research and technology has allowed them to pioneer new ways to interpret and present a tricky subject matter to understand what the change of light is likely to be experientially. This unique approach allowed us to produce a persuasive and successful narrative for the Inspector at a recent inquiry for which GIA produced exceptionally impressive evidence.”
