We model the scheme and its surroundings, test the impact on neighbouring windows and gardens, and assess daylight within the new homes, with practical suggestions if any rooms or windows fall short.
When you'll need it
- Taller buildings or extensions near existing homes
- Higher-density residential schemes
- When a planning officer requests a daylight report
- Early massing studies, before the design is fixed
What's included
- 3D model of the site and surrounding buildings
- Vertical sky component and daylight distribution tests
- Sunlight to windows and overshadowing of gardens
- Daylight within new homes to BS EN 17037
- Massing and layout recommendations
- Planning-ready report with clear findings
Daylight & sunlight FAQs
When is a daylight and sunlight assessment needed?
When a scheme could noticeably reduce light to neighbouring homes, or when the council wants evidence that new homes will be well lit. Taller and denser schemes are the usual triggers.
Can you help shape the design rather than just report on it?
Yes, and it's the best time to involve us. Testing massing options early avoids a failing report late in the planning process.
Which guidance do you follow?
The BRE guide BR 209 for impacts on neighbours, and BS EN 17037 for daylight within new homes, as most councils expect.
