As innovative Surveyors in Rights of Light, Daylight and Sunlight, Neighbourly Matters, Wind Analysis and Plan Tech, we provide a more holistic perspective to planning and development. By using cutting edge technology to analyse and inform, we provide a broader and more contextual approach. Challenging current thinking, we deliver incisive 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 us to produce a persuasive and successful narrative for the Inspector at a recent inquiry for which GIA produced exceptionally impressive evidence.”

Thought leaders and initiators

Our research and our broader approach to planning through contextual studies, amenity and the use of cutting edge technology, enables us to identify significant issues very early on in the process. This ‘real life’ approach to planning, looking at problems in their widest context, allows us to be more agile and responsive for our clients, whilst considering the needs of all affected by a project.

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

Challenging the guidelines

With a growing population and up to 70% of us living in cities by 2050, GIA recognises the inherent tension between the need to meet development targets against the right for our citizens to have a decent quality of life. When holistically considering new development, we focus on the wider context of the urban environment, considering the different aspects of human wellbeing and amenity.

“GIA is leading the way in influencing London policy in a pragmatic and positive way, challenging conventional thinking towards densification, demonstrably improving the optimisation of Land in London”.
