International architecture practice 10 Design has revealed its design concepts for an ambitious redevelopment of Edinburgh’s city centre.

The project will transform the former Royal Bank of Scotland (RBS) site on Dundas Street into a first-rate mixed-use development, which will create a new urban centre, providing a significant addition of public realm, including hotel, retail, residential and office components.

The development will replace the existing car park and the ex-RBS office with a new integrated development that respects its unique location bordering the World Heritage Area in a respectful but contemporary design that will reconnect the King George V Park with both the New Town and the wider urban context.

Robust, low maintenance natural materials and the addition of health and wellbeing components – such as a new health and fitness club – will create new amenities for both the local and wider community to "add quality of life and sense of place".

The form and character of the proposed development will create a new urban hub while being sensitive to the surrounding area. It is anticipated to have a population density in line, or lower than 165 people per hectare, which is the average existing population density of the locality (based on current census data).

Ediston Real Estate and Orion Capital Managers submitted plans for the New Town Quarter – previously referred to as New Town North – for planning earlier this year, following an extensive public consultation exercise through the pre-planning process.

Gordon Affleck, Design Partner at 10 Design, said: “The site has offered a unique opportunity to reconnect the park to the north and west of the city.

"Respecting both the sensitivity of its location with the New Town and the complexities of the physical restrictions of the site has proved challenging, however we believe the quality and diversity of the development uses and the new public realm will create a focal point and positive amenity for both the local and wider community.”

The proposed project considers a series of landscape and amenity terraces to maintain vistas while creating new pedestrian and cycle routes, greatly improving permeability in this part of the city.

The key route will connect Dundas Street through the heart of the site to King George V Park with a variety of interconnected landscape terraces that absorb the steep level changes of the site creating a new East-West narrative, transitioning from a more green environment of the park to the more urban setting of Dundas Street.

The route will create a new public plaza accommodating retail and restaurants, where community events can take place.

Structured planting design will create an activated landscape link to the park while providing new entry points for the key components of the development, maintaining a car free pedestrian environment across the site.

Ross McNulty, Development Director of Ediston Real Estate, said: “We are aware this is a complex and large site, with important links to some of Edinburgh’s finest streets and green spaces.

"We are making sure we take the right amount of time to consult properly with local people to deliver a market leading development to benefit both the community and the wider city.”
