01 / About
One team from first idea to technical resolution.
Established in London in 2018, Fifth Element Interior Designers is a multidisciplinary design and technical consultancy. We bring architecture, interior design, building engineering and commercial thinking into one coordinated process.
Our work is grounded in how a space will be used, built, approved and operated. We work across borders, adapting to local codes and project requirements, and coordinate with appropriately qualified local professionals where statutory sign-off is required.
