The document provides details on the proposed masterplan for redeveloping the Seafield site in Edinburgh. It includes an analysis of the existing site and context, as well as proposed land uses and elements for the new development called "The Tide". The key elements proposed include a lighthouse auditorium as a focal point, residential and commercial dock-style buildings, restaurants and bars, a watersports center, and community gardens. The development aims to create a mixed-use destination for leisure, living, and working that capitalizes on Edinburgh's tourism industry and reputation for the arts.
