Twin and Earth is an independent engineering and sustainability consultancy. We bring together knowledge of technical design and practical implementation to deliver exceptional buildings, products and corporate strategies.

We provide independent, tailored advice to our clients to deliver practical solutions that are well engineered, simple and pragmatic. What sets us apart is our ability to challenge the norm and provide solutions that work both on paper and in practice.


Formed in early 2014, we collaborate with architects, developers, contractors and engineers, end users and operators of buildings, product manufacturers, and public and private sector organisations.

Our services include;

  • Providing concept and detailed engineering and sustainable design solutions for new and existing buildings.
  • Supporting businesses in the development of more sustainable products.
  • Helping public and private sector organisations to develop and adopt more sustainable operations.

At our core is a desire to create truly integrated sustainable solutions that are underpinned by expert knowledge of building physics, engineering systems, sustainable product design and corporate sustainability drivers.
