The talk will address the two main elements that designers should consider in relation to natural light. These are (i) daylight and sunlight, which local planning authorities often wish to see assessed to understand the impacts of development on existing buildings, and (ii) rights of light, the private property right that owners of affected buildings can use to influence the volume of adjacent developments or to claim damages if too much light is lost. The presentation will include the following contents:
Daylight, sunlight and overshadowing
- Regulatory framework - the BRE guide and BS8206
- Existing tests and recent changes
- New considerations
- Appendix F - Setting Alternative Targets
- Appendix H – Trees and Hedges
Rights of light
- Site Surveys
- Sufficiency of light
- Example of contour analysis
- Valuation of damages
- Managing Rights of Light
- Case study
- Practical applications - envelopes and 'cut-backs'
Gary Blackman BSc (Hons) FRICS. Gary is an Associate at Malcolm Hollis and specialises in rights of light and daylight and sunlight matters.
His work predominantly involves assisting clients and designers during the planning stages of development projects and advising on the impacts that developments will have on rights of light and daylight. This includes negotiation with affected parties to avoid potential disputes and to mitigate risk.
Changes in planning policy toward sustainability and recent high profile cases in these fields, such as the Heaney Case, have focused the industry on opportunities and risks associated with daylight and sunlight amenity and rights of light. This is leading to an ever increasing demand for good quality and timely advice and to address this Ian has developed a national team of specialists to provide that advice.
