Daylight, sunlight and overshadowing is a material planning consideration largely guided by the Building Research Establishment’s, Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice (2011). The guide sets out numerical target values for various methods of assessing natural lighting adequacies both within and around buildings. Failure to comply with BRE criteria may give rise to unfeasible planning conditions or refusal of planning permission.

At Trident, our Rights of Light team’s natural light competencies extend to the planning arena. With over 20 years’ experience in identifying potential planning constraints, developing risk mitigation strategies and producing bespoke reports in support of a significant number of successful planning applications, our department director Dan Wade and his team have acquired an unrivalled understanding of the varying expectations of UK planning authorities.

Whether required to advise on the feasibility of design objectives pre-purchase or quantify compliance levels for a fully developed scheme, our range of sophisticated analyses can help achieve maximum density whilst optimising good design. Assessment findings can be illustrated to support outline planning submissions, detailed planning submissions, Environmental Impact Assessments or BREEAM assessments.
