Fresh proposals for a £20m redesign of Union Terrace Gardens in Aberdeen have been revealed.

The new blueprint, drawn up by Olympic Park designers LDN Design, features a new walkway route from Union Street, providing better disabled access and scope for keeping as many trees as possible.

The plans were released on Friday to coincide with a public consultation which will run for a week.

A debate over the regeneration of the park has been running for years.

Councillors narrowly rejected Sir Ian Wood's controversial £140m plan to bring it up to street level in 2012.

Under the latest proposals, the central lawn would be kept as a "flexible space" for large-scale gatherings and events, while a new "entrance plaza" and cafe would be created opposite His Majesty's Theatre to provide a venue for smaller activities.

A "grand staircase" would be reinstated as part of the new routes into the gardens from Rosemount Viaduct.

The new accessible walkway into the gardens would also include lift access into the lower level of the gardens, through an entrance building on Union Street.

Lift access would also be provided from Union Terrace into the upper level of the gardens, while new disabled parking spaces would be created near the walkway routes.

Aberdeen City Council leader Jenny Laing said: "I am delighted with the proposals that LDA Design has brought forward for Union Terrace Gardens as part of our city centre masterplan.

"LDA was tasked with improving access, amenity and activity while conserving UTG's rich heritage - what residents asked for during a consultation on the masterplan itself.

"These proposals respect the unique character of the Gardens while making the space more usable for all. I would urge all residents to share their views so the LDA can refine the design and ensure we get the best result for everyone."

Deputy council leader Marie Boulton, who chairs the cross-party city centre regeneration board, said: "LDA Design has presented us with a vision we believe everyone can unite behind.

"They have taken as their starting point priorities spelled during the masterplan consultation, in which thousands of people participated.

"It became very clear that UTG was important to residents as a garden space, one that would require sensitive handling but also significant interventions to make it a place for all.

"LDA Design has responded magnificently to those wishes and challenges, honouring UTG's character and setting while offering imaginative new ways to transform the gardens and the Denburn Valley."

An online survey on the plans will be open until December 9.
