Exciting development for the Park

The Sill: National Landscape Discovery Centre

The Sill is an exciting £14.2 million initiative of international importance that will create a Landscape Discovery Centre and new YHA Youth Hostel at Once Brewed in Northumberland. The Centre will open Summer 2017.

The Sill – Landscape Discovery Centre will enable people of all ages and circumstance to understand and explore the landscapes, history, culture and heritage of Northumberland. Its major purpose is to allow the landscapes of Northumberland National Park and beyond to be accessed by even more people, including children, families, older people, disabled people and those who are less confident at exploring natural places.

The Sill

The design was finalised after months of extensive public consultation and refinement. The Sill design will harmoniously reflect the distinctive Northumbrian landscape in both its shape and the materials used in its construction. Its centrepiece will be a beautiful Whin Sill grass roof, planted to replicate the unique natural grasslands of the surrounding area. The Sill’s fully accessible living roofwill sweep gently upwards, giving visitors a bird’s eye vantage point across one of the UK’s most magnificent landscapes and the UNESCO World Heritage Site of Hadrian’s Wall. 80% of the externals are constructed from local stone and timber.

Architects vision of The Sill

The new hub will host extensive learning and participation activities, with the aim of welcoming new visitors to Northumberland National Park and inspiring future generations to celebrate, enjoy and conserve the incredible landscape of the Park and well beyond.
