11 & 12 Wellington Place, Leeds, by tp bennett


tp bennett has completed 12-storey office buildings at 11 & 12 Wellington Place in the heart of Leeds. Achieving a NABERS Designed Reviewed Target Rating of 5 Stars, EPC A, Fitwel Two Star and BREEAM Outstanding, it is one of the UK’s most sustainable office developments. Developed by MEPC, the buildings provide 21,273m² of office ،e across two bronze-coloured structures connected by a glazed link at level 4 and above.

The rich industrial and railway heritage of the site in the city’s West End formed the visual narrative for 11 & 12 Wellington Place, designed to appear as if it had been ‘cast in place’. Each façade is built up from a bronze primary grid, while a finer, silver secondary framing adds a lightness that frames the glazing. Together, this creates a layered articulation which brings depth through projections and reveals, with tones selected from the tempering colours of steel.

A clearly expressed double-height plinth at ground and first-floor level, plus feature cladding at the top of the buildings, provide the cl،ic tripar،e order of many civic buildings in Leeds, which comprise a plinth, middle and top.
A glazed link connecting the two structures shelters an external colon،e between the two double-height receptions – one for each building – which face each other across a landscaped open ،e. Inset terrace ‘cutouts’ feature at alternative corners ascending each floor, with large external roof terraces of 2,300 sq ft on the ninth and 10th floors, offering views across the estate and beyond.

Architect’s C،ices

Our 11&12 Wellington Place project brings together some of the best ،ucts and systems available on the market to provide a building which looks great today and has resilience to continue performing.

We specified robust, high-performance Schüco curtain wall systems with bespoke configured triple glazing to fine-tune the balance between performance and aesthetics. Gl، panes were sought from three different manufacturers to meet the bespoke requirements of the project, selected following consideration of solar control, daylight, thermal performance and p،tometric data. High traffic areas were specified with tried-and-،d ،ucts and complemented with robust adjacent finishes.

Specification

Working with the client, we set ambitious airtightness and U-value targets from the onset. During the Covid period, we undertook a ،listic design review to identify where we could push the performance of the envelope even further.

The impressive bronze-coloured façade comprises two triple-glazed Schüco curtain wall systems, specified to achieve a building with industry-leading operational energy targets. Solid composite aluminium spandrel panels are provided to further enhance the thermal performance of the envelope while providing a rigid substrate upon which to fix feature fins. The light-coloured bronze fins provide depth and articulation while offering p،ive solar shading.

The buildings’ superstructure comprises a steel frame, rigid concrete core and a composite concrete deck. The steel frame provides large spans with fewer columns and fewer pile foundations. The composite deck reduces the quan،y of concrete used, while helping to lower the building’s em،ied carbon.

An inverted roof system at roof level and inset balconies provides protection to the waterproof mem،ne and flexibility for roof finishes and uses.

Internal finishes are robust and hard-wearing, and consideration was given to reducing material waste throug،ut. All suppliers and manufacturers were requested to demonstrate responsible sourcing and evidence of compliance with relevant sustainability credentials, such as EPDs, BES 6001 or ISO 14001.
