Oxford Space Systems – The Zephyr Building

Oxford Space Systems needed a new Harwell headquarters to support its expanding work in deployable satellite technology – a space designed for precision, collaboration and future growth.

We were appointed to design and procure the full fit out of Unit 1 in the Zephyr Building, turning a blank 1,500 m² shell into a purpose-built HQ and manufacturing hub for 50 technical staff.

Designing precision from concept to completion

Our building surveying, cost management and health and safety teams led the work from the first schematic layouts – used during lease negotiations – through to construction.

We developed clear, detailed Employer’s Requirements that included a 300 m² ISO Class 7 cleanroom, a gantry crane and high-spec Cat B office space. We secured landlord approvals via a Licence for Alterations, brought specialist cleanroom designers into the team and negotiated procurement with a local fit out contractor. Each step helped keep quality high and progress steady.

A specialist facility built for the future

The completed unit gives Oxford Space Systems a modern workspace that blends precision-engineering capability with flexible office areas. The ISO14644 compliant cleanroom supports the manufacture and testing of deployable satellite structures, while open-plan offices and meeting spaces create a place where teams can collaborate, solve problems and share ideas.

Powering the next generation of space innovation

This new facility gives Oxford Space System everything it needs to expand operations, attract talent and develop technologies used by leading satellite builders. It also strengthens Harwell’s role as a global centre for space research, showing how practical design and thoughtful engineering can fuel scientific innovation for years ahead.
