A principal practice in light, its implications in design and its effects on its neighbours. We provide a more creative, lateral approach. By challenging current thinking, we deliver incisive and fresh solutions for every project on which we consult.

“Without hesitation, I would recommend GIA as they are unequivocally the leading innovators in their industry. While the BRE Guidelines are a good starting point, it’s clear that in a city which is constantly evolving and developing, context is king when considering daylight and sunlight. Their approach goes far beyond a simple numerical calculation of light. Instead their 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. By way of example, this unique approach allowed them to produce a persuasive and successful narrative for the Inspector at a recent inquiry for which GIA produced exceptionally impressive evidence”.
