This gateway site to the city centre will include office, retail, residential and leisure areas. Central to the plans for phase one is a 60,000sq ft office building at the heart of the 5.5 hectare site, which will look out on to the Keel Line. There will be 19 separate buildings or blocks built over a number of years to create a flagship development for living, working and relaxing.

The masterplan has been designed to provide active streets, with small scale retail, cafes, restaurants and leisure uses occupying ground floors, and trees and planting adding to the attractiveness of each street.

New public spaces are being designed to invite people to enjoy views of the Wear and the bridges, as well as providing space for events such as food and drink festivals and music events.

We are also developing ideas to animate the cliff-edge to include a restaurant partially set into the cliff-face. We propose that access to Riverside Park is improved – which could help reduce anti-social behaviour in hidden areas along the lower embankment.


One of the key objectives of the masterplan is to provide a scheme which is well connected to the city centre.

The layout of the streets is designed to provide maximum movement through the site, as well as introducing new pedestrian access points onto St Mary’s Way. There will also be a new pathway along the entire edge of the cliff and completion of the Keel Line across the site to connect to this pathway.

Plans are being drawn up to provide a promontory which could connect the Keel Line to Riverside Park below.


The north west corner of the Vaux site is the focus for new homes with fantastic views over the Wear. The Keel Line, a pedestrian link from the new Keel Square to the cliff-edge will connect the site with the Riverside park, city centre, new developments at the MAC Quarter, the High Street and the Bridges Shopping Centre.

Each street will have its own character, created using distinct materials and landscaping. In total there is provision for over 200 homes in this area.


We aim to provide Grade A office space in Sunderland city centre through the Vaux site. With virtually no Grade A space at present, companies requiring this space are taking their business outside of the city. The Vaux site provides a huge opportunity to have a positive impact on the future of the city’s economy and our development proposals incorporate a masterplan which aims to attract investors and create demand, whilst at the same time providing a well-thought out scheme.

The Siglion proposal allows each development block to be built separately, as occupiers and investors come forward, but is flexible so that blocks can be combined to accommodate potential larger space users.

Architects Fielden Clegg Bradley have designed Phase One of Vaux incorporating a 60,000 sqft grade A office building designed to achieve BREEAM Excellent environmental rating. The building will be a step change in terms of quality for the city and help to attract new businesses and employees to the site.


During the early phases of development, when much of the site is vacant, spaces will be temporarily landscaped to provide areas for ‘meanwhile’ uses. This will allow the space to be used creatively during the early construction phases, creating interest and activity on the site and keeping it open to the public.
