A South West net zero carbon building has reached practical completion.

The office has been commissioned by CEG and delivered by Beard Construction. The building, 1000 Aztec West in South Gloucestershire near Bristol reused the existing frame and shell to deliver the development.

The addition of a new floor and three-storey atrium to the centre of the new, all-glass structure has expanded the building from 38,000 to 80,000 sq ft, capable of housing an 850-strong workforce.

Paul Richardson, investment manager at CEG said: "1000 Aztec West was redesigned with modern tenants’ key requirements in mind. From environmental sustainability and data connectivity, to the wide variety of onsite facilities designed to maximise staff wellbeing, we have delivered city-centre specifications not seen in out-of-town Bristol before.”

The development has achieved BREEAM Excellent and EPC A. The building is powered by renewable energy and boasts energy-efficient heating, cooling and lighting systems. As well as saving some 1.7 million kg of embodied carbon, coupled with its Net Zero in Operation performance.

Architect Ed Hayden, director of Scott Brownrigg, said: “Aztec 1000 takes advantage of location, orientation and existing materials to maximise ‘fabric first’ design principles and create a stunning new addition to the architecture of Bristol’s workspace.

“Sustainability is achieved by retaining as much of the existing material as is practically possible and building passive energy and carbon saving strategies into the layout and fabric of the design. Overheating in the summer is negated with the careful specification of extremely high performing solar control glazing and the inclusion of ‘light shelves’ which bounce daylight into the heart of the building.

“The result is a strikingly contemporary reimagining of the workplace, which Scott Brownrigg is proud to have supported CEG in creating.”

The agents marketing the development are Jones Lang LaSalle (JLL), Cushman and Wakefield and Carter Jonas. Ian Wills, director office agency and tenant representation at JLL said: “We knew the building would be good, but walking the finished floors it is clear just how inspiring this work environment is compared with the usual business park offer. The semi-exposed ceilings, full height glazing, views of the lake and park, the impressive reception, gym and café make this the most amazing place to work.”
