trinity shopping centre leeds

The city of Leeds in northern England is the fastest-growing city in the UK. A large shopping centre with an area of about 100,000sqm is being built right in the heart of the city in order to invigorate an area dominated by buildings in baroque, classical and Victorian styles. The design by the Chapman Taylor architectural practice weaves together old and new urban structures and integrates an existing shopping centre. Inviting shopping arcades on two floors are topped by a third floor with restaurants and cafés offering panoramic views across the city and the neighbouring 18th century Trinity Church. A large open space in the centre of the public thoroughfare below invites shoppers to stop and linger. 

  • A delicate, sweeping glass roof spans over the streets and the central square. This roof consists of eight separate segments that slide over one another where they meet. Half of the approx. 3,700sqm of glass is to be found in the imposing main dome which spans 48m across the central square. It is here that the biggest challenge faced by seele on this project becomes readily apparent: The fully welded steel structure is supported on four different buildings, each with its own particular expansion behaviour. The situation is similar for the seven smaller roofs. All the roofs handle the movement through a combination of fixed and movable bearings. The latter can accommodate axial rotation, displacement and deflection. Added to this is the complex water run-off situation that had to be considered in the design work. The lack of space on this city-centre site and the fact that no two parts are identical called for seele’s efficient logistics management to ensure a successful project.
