Daylight/Sunlight/Overshadowing

Our Daylight, Sunlight and Overshadowing work is conducted under the umbrella of Trident’s Rights of Light service but falls under the jurisdiction of Local Authority Planning. All assessments unless specified will be undertaken in accordance with the guidelines of BRE 209 Paper “Site Layout Planning for Daylight and Sunlight, A guide to good practice” by Paul Littlefair (2011),

Similar to our Rights of Light service, Trident has a three-tier outlook for DSO advice:

  • 1st Tier Analysis – the team will conduct a preliminary outline analysis in order to identify and comprehend the initial DSO planning risks to developments but also the potential risk to their neighbours.
  • 2nd Tier Analysis – preliminary / advanced technical analysis quantifying DSO impact through detailed technical assessments using specialist DSO software. We analyse all forms of daylight assessment, consideration of probable sunlight hours as well as transient and permanent shadow calculations amongst other factors. Once this analysis has been founded, Trident will be able to provide clients with impartial and strategic advice for compliant envelopes or amendments, dependent on the outcome of each specific project.
  • 3rd Tier Analysis – Trident’s specialist offering for Daylight, Sunlight and Overshadowing at this level covers EIA assessments, BREEAM assessments (for residential and office properties) and representation at planning committees and inquiries as well as public inquiries.

Trident treat Daylight, Sunlight and Overshadowing services like all other services by combining cutting-edge technology and experienced staff to deliver top-quality expedient advice, saving you time, money and stress.
