Over the last week, our Spirax Group colleagues have been settling back into our new headquarters after moving in on 11 March. Now we are back home, we wanted to share some of the features of the development. 

Project Oak, is the name of our redevelopment project which includes the demolition of the extensions to Charlton House. The Grade II listed building has been home to our Group for almost 80 years, so it required a sympathetic yet fresh approach to create a sustainable and modern workplace.   

The new extension enables colleagues to work flexibly with lots of space for both informal and formal meetings, while being able to take advantage of the wonderful countryside views from the wide expanse of windows. Colleagues can move from the new open plan floors into the original house using the mezzanine levels accessible through stairs and lifts. The building also includes a fitness and wellbeing area that seamlessly flows into biodiverse landscaping outside.  

To support the efficiency and sustainability of the building for decades to come, we have installed air source heat pumps (ASHPs) on the roof. Other sustainability features include solar control glass, which limits solar gain, maximises daylight and minimises the need for artificial lighting, and active chilled beam technology ensures consistent temperature control. 

Our grounds also include a biodiverse garden area for colleagues to enjoy. In addition to this space, we have installed electric vehicle charging points alongside our car and bike parking provision.  

The sustainable focus of the new build led to a Building Research Establishment Environmental Assessment Method (BREEAM) rating of ‘Outstanding’ at Design Stage. This reflects Project Oak’s best practices in sustainable building design, construction and operation. 

BREEAM recognises the top 0.5% of sustainable new builds in the UK and their rating takes into consideration how the design of the building supports its reduced impact on the environment, as well as efficiency in energy consumption and reduced CO2 emissions.  

As well as protecting a legacy of nearly 80 years on this site, the HQ has been built with the next 50 years in mind and is designed to have a positive impact for colleagues and the local community as part of our continuing commitment to Cheltenham and the wider area.
