The Sill Landscape Discovery Centre

Twinkle Twinkle Little Star

The SILL building is located in Europe’s largest Gold Tier Dark Sky Park. As a result, the external lighting design and the control of the internal light spill had to be carefully design and managed. At the outset of the project measurements of the existing light spill and site conditions were taken and these acted as a baseline condition. Despite the new building being three time bigger than the original and having more glazing, to allow visitors to experience the amazing views, the lighting design meets the dark sky park criteria.
