Plans for a residential, retail and spa hotel development at Edinburgh Marina have been submitted.

Developers said the 400 berth marina will be the focal point of Granton Harbour’s regeneration.

The masterplan lodged with the City of Edinburgh Council is believed to be the first new Marina next to a capital city in Europe for several decades, providing a major boost to inward investment in Edinburgh of over £300 million.

The development will deliver new homes for over 4,000 residents as well as local employment opportunities for up to 700 people, whilst the new masterplan provides for improved marine services, including a larger community boatyard and improved facilities for the Royal Forth and Forth Corinthian yacht clubs.

The residential content of the development remains virtually unchanged from the previously approved plans, but now provides for a significantly greater offering of family sized housing for rent. The total area of the proposed new retail and leisure space remains unchanged from that approved in January 2014 - 9220 sq.m and 4220 sq.m respectively. However, the layout has now been redesigned to provide a centre to the retail, commercial and leisure space, easily accessible to both residents and visitors.

The revised scheme also makes provision for the proposed new transport facilities in the area, including the extension of the tram service and a potential fast link ferry service to and from Kirkcaldy, as well as facilities to accommodate cruise ship tenders.

A spokesman for the developers, Granton Central Developments Limited, said: “We are very pleased with the way in which our development plans have been supported by the local community and we look forward to starting work on this exciting project in 2015. We hope that Edinburgh Marina will soon be not just a gateway to Edinburgh, but a focal point of an exciting and energetic new community.”
