The new Rocket Field Building provides a new focus point for visitors to the island, providing information and interpretation, an area for watching birds, and a muster point for groups. The building is constructed of stone masonry construction using locally-sourced and worked whin stone with a turf roof. The site is a Ramsar and SSSI site.
The Lookout Tower is a refurbished former Coastguard lookout tower dating from the 1950s. The original rooftop brick lookout cabin has been removed and replaced with a fully glazed, steel-framed lantern offering 360˚ panoramic views over the island, local nature reserve and estuary and Farne Islands. The steel frame has been designed to minimise interruption into this spectacular field of view. In addition to the new lantern, the masonry of the original tower has been consolidated and visitor access into the building has been improved through the construction of a new internal steel staircase.
