Plans for sustainable office buildings have been given the green light on a prime 60,000sq ft business site situated at Exeter Business Park, close to Junction 29 of the M5. The approval follows proposals by sustainable property developer Grenadier Estates, a sustainable partner of Exeter City Futures. Grenadier is aligned with our goal of making Exeter’s buildings energy independent.

Plans for the top-end energy-efficient office have been now been approved by Exeter City Council. Grenadier is looking at building a substantial 40,000 sq ft office building suitable as a corporate headquarters, and a lesser 20,000 sq ft office building.

Peter Quincey, Director of Property at Grenadier Estates, said: “All of our developments are built with sustainability at the forefront, and the new site at Exeter Business Park will not be any different. All buildings will meet stringent standards and we will aim to optimise efficiency through a fabric first approach combined with the use of renewable systems.

“The development of sustainable infrastructure is important, as the UK is under increasing pressure to reduce its carbon emissions,” Peter continues. “New developments that harness sustainability have a positive effect on the environment, and help to reach carbon targets. Following our successful development of our head office at Oxygen House on the business park we are confident that we can create super energy-efficient buildings that will benefit the environment, as well as Exeter as a city.”

Energy Efficient Buildings

Grenadier Estates announced plans to build a 22,000 sq ft, EPC A rated office building, also within the same business park. The construction of Emperor House has already begun, and will include key energy efficiency features such as a new 138 kW solar array.

Grenadier Estates is also invested in redeveloping old properties to bring them up to a high standard of energy efficiency. St Margaret’s is another project currently being undertaken – a retrofit of a Grade ii listed building in St Leonards, Exeter. The challenge with St Margaret’s is to bring it up from an EPC E/F rating to an A rating.


Exeter City Futures working alongside Grenadier Estates is a great example of how forming partnerships and collaborative projects will help us to achieve our energy independence goal. These new developments are inline with recommendations outlined in Energy Independence 2025 to make our buildings more energy efficient. Grenadier is also aligned to our goal of reducing congestion by finding better ways of getting people to work, with solutions which will be validated within the business park.
