CAR Structures has a reputation for intelligent design, for practical and innovative solutions using new materials, and for conserving and restoring historic structures.

Creative structural design is both an art and a science. We use imagination to create ideas, engineering science to predict behaviour under load, and practical knowledge to devise construction methods. Our skill is engineering ‘know-how’, achieving more with less, and designing safe and economical structures.

The team has many years of experience with both new and historic buildings in a wide variety of contexts, including colleges, churches, laboratories, and cultural, sports and residential buildings. Staff are able to deal with projects of all sizes – we are a general practice of structural engineers.

We have worked on high-profile public buildings like the Royal Academy of Arts, the Hippodrome Theatre and Cafe Royal in London, but also more modest house extensions and basement extensions. We have also designed the structures behind many new buildings for Cambridge University and Cambridge Colleges.

We enjoy a challenge, and we revel in bringing together environmental concerns such as low embodied carbon, and minimalist structures, alongside achieving best value for clients, designing beautiful buildings, and ensuring that buildings are a delight to live, work and play in.
