Transforming Alnwick Garden to its former glory

Our civil engineering and construction capabilities transformed a derelict 12-acre garden within the grounds of Alnwick Castle.

Located within the grounds of Alnwick Castle in the heart of Northumberland, we transformed a derelict 12-acre garden into a majestic tourist attraction.

Originally constructed in the 1750s and further developed during the 1850s, Alnwick garden was amongst the finest in Europe. During the 20th Century, the site fell into disrepair after the Second World War.

Using our civil engineering excellence, we helped revitalise the derelict 12-acre garden within the grounds of Alnwick Castle, featuring a centrepiece Grand Cascade and one of the world’s largest treehouses.

Our project teams have completed a series of contracts at the attraction including:

  • The Grand Cascade
  • The Pavilion and Visitor Centre
  • One of the world’s largest treehouses 
  • The formation of three new gardens
  • A playground and car park

Award winning

Alnwick Garden Pavilion was honoured at the Royal Institute of British Architects Awards (RIBA). The judges felt the emphasis on sustainability and awarded the Pavilion and Visitor Centre with the Composite Steel and Timber Structure Award.

The treehouse was also recognised at the Local Authority Building Control Awards (LABC) and was awarded the Best Access/Disability Regulations Innovation award.

This is a complex scheme, but it has a clear design vision and is innovative in its use of materials.
