A heritage project at Preston Tower has won two top architecture awards.

The project team received the Conservation and Heritage Award and the Building of the Year Award at the Edinburgh Architectural Association Awards for Architecture.

The £1.1 million project at the Scheduled Monument in Prestonpans, parts of which dates back to the 15th century, was completed earlier this year.

The first phase  involved repairs to the doo'cot, installation of new interpretation boards, a new garden seating area around a carved stone contemplation circle, and new paths.

The second phase featured specialist stonework and plaster repairs, renewal of metalwork to the tower, installation of external CCTV and lighting, and an external staircase to allow public access to the inside of the tower for the first time in over 40 years.

Councillor Colin McGinn, cabinet spokesperson for community wellbeing at East Lothian Council, said: "The heritage project at Preston Tower was a very successful initiative which saw East Lothian Council work in partnership with local residents including Prestonpans Community Council, the Friends of Preston Tower, Groves Raines Architects Studios, the National Trust for Scotland and Historic Environment Scotland.

"In recognising the significance of Preston Tower to the local community and as an historical landmark, great care was taken at every stage to ensure that the works were of high quality whilst being sympathetic and sensitive to the structure and fabric of this Scheduled Monument.

"I’m absolutely delighted to see the project recognised at the Edinburgh Architectural Association Awards for Architecture – huge congratulations to everyone involved.

"Their efforts will ensure Preston Tower can be appreciated by generations of local people and visitors well into the future."

All of the works were led by conservation-accredited consultants at Groves Raines Architects Studios, supported by the National Trust for Scotland.

Construction work was carried out by East Lothian-based firm Campbell & Smith.

Bryan Dickson, head of building conservation policy at the National Trust for Scotland, said: "We are thrilled that the team’s efforts are recognised in this way, with both awards recognising the spirit of community engagement and the level of thoughtful interventions required in providing access for future generations."

The repair project to the tower, doo'cot, and gardens was funded from a variety of sources including the Scottish Government through its Town Centre Fund and Place Based Investment Programme, as well as the UK Government's UK Shared Prosperity Fund and by the National Trust for Scotland.
