Trinity Leeds

Waterman are providing a full scope of structural and civil engineering services to the landmark retail development; Trinity Leeds, which is the largest retail project to open in Western Europe in 2013.

Set in the UK’s third largest City, the multi-million pound City Centre development is the first major retail-led development in the UK to get the go ahead in recent times and is programmed to open 21st March 2013.

Spread across a tapestry of arcades that traverse three of the busiest shopping streets in Leeds (Briggate, Albion and Commercial Street) and covering one million square feet over three levels, Trinity Leeds will be a retail beacon. It will attract international brands and boutiques to Leeds and give shoppers 120 sensational shops, stores, restaurants and cafes to explore at their leisure.

The retail line-up includes leading UK and International retailers, with flagship stores for Superdry, Hollister, Mango, Topshop, Topman, H&M, Next and River Island. These are all anchored by Marks & Spencer, in their home City store and a dazzling new three floor Primark.

D&D London will be adding two roof top restaurants in Trinity Leeds to its map of acclaimed eateries in London, Paris, New York, Copenhagen and Tokyo. Meanwhile, boutique cinema chain Everyman will open its first venue outside of London, providing Trinity Leeds with a film offer that sits independent cinema alongside screenings of the latest blockbuster movies.

Trinity Leeds’ unrivalled location ensures an unprecedented footfall. On the doorstep there are 3,500 car parking spaces, exceptional road and rail links and 18.2 million people travelling through the nearby bus and train stations annually. Trinity Leeds is connected in every way to the city and beyond.


The title for the project ‘Trinity’ was derived from the adjacent Grade 1 listed building ‘The Holy Trinity Church’. The development has been designed to enable the church to be seen from as many view points as possible; indeed the mall roof has been designed and is predominantly glazed such that the spire can be seen from within the development.

The new structure, founded on sandstone, comprises a tanked basement service yard and a structural steel superstructure which has been modelled using Masterseries 3D design software.

The fast-track composite superstructure utilised stability frames to improve retail flexibility and local ‘thin floor’ construction techniques to overcome severe headroom restrictions. Precast twin wall construction, cladding panels, prefabricated service riser modules and the roof top plant room has assisted in minimising the construction programme.

The specialist grid shell feature roof and micro thin mall bridges will bring added excitement to the experience.

As a BIM project, we have provided on-going support via the collaboration website by uploading our Revit model. This model is constantly updated during the life cycle of the project as part of the shared knowledge resources and has formed a reliable basis of team decision making.

The Trinity development will be the culmination of Waterman’s fifteen years’ involvement with the site; first for USS; then Caddick Developments and finally Land Securities.
