ShellCo is a Stevenage-based construction company focused on structural shell delivery and defined building packages for developers, contractors and private clients. The lead service is structural shell construction, coordinating major stages from below ground through to a watertight handover. Individual stages and wider packages are also available.
The company operates by first understanding the project's specific needs, starting with current drawings, site information, a defined package, and an honest view of the programme. This approach ensures a clear scope and direct communication throughout the project lifecycle. ShellCo works with developers, main contractors, and self-build clients, providing commercial clarity and a practical conversation based on developed plans and site position.
ShellCo's core work is centred on Stevenage and Hertfordshire, but they consider projects farther afield when the scope, programme, and travel costs make practical and commercial sense. They aim to reduce gaps between separate appointments by offering coordinated stages under one defined package, ensuring clear inclusions and interfaces before pricing.
