Daylight, sunlight and overshadowing are material planning considerations generally guided by the Building Research Establishment and British Standards Institute. With expanding populations and density in our cities, safeguarding natural light to buildings is becoming increasingly important and presents one of the biggest challenges faced by developers and local authorities.

At Trident, our Rights of Light team’s natural light competencies extend to the planning arena. With experience of working on a full spectrum of planning applications from rural extensions to urban skyscrapers, our team of experts have accumulated a comprehensive understanding of the varying expectations of UK planning authorities.

Using specialist analysis software, Trident’s expert CAD technicians apply innovative techniques developed over a number of years to maximise density and optimise natural light provision. Our services can be tailored depending on the project requirements and include a suite of planning and environmental assessments which can be applied at any stage to demonstrate site potential.

Our experts can also satisfy all daylighting and sunlighting provisions set out in the suite of BREEAM and WELL Building technical guides. Speak with one of our experts for further details on our environmental assessment capabilities.
