Values
Design and build develop together. Engineering, fabrication and installation are considered in parallel within the yard.
Decisions are informed by the structure and the practical demands of the work. Details are resolved before the next stage begins and the finished result is often simple.
James’ Wharf is the clearest expression of this approach. It is a working shipyard shaped by how the work is carried out each day.

Restoration
Restoration begins with understanding what is already there. Historic vessels and listed buildings are studied closely before any work is carried out.
Intervention is measured and purposeful. Character is retained, structure is strengthened and each element is prepared for continued use.

Our Team
The strength of Calshot lies in the people who work here. Our team includes bespoke joiners, engineers, shipwrights, welders, painters, electricians, plumbers and designers who bring a depth of skill and a shared commitment to doing things properly. Everyone is close to the work and every decision is shaped by hands-on knowledge. This is a place where craft is taken seriously and where collaboration happens at source.

Sustainability
We prioritise repair and retention wherever possible. Existing structures are kept in service and reclaimed materials are used when appropriate.
Environmental responsibility is part of daily decision making in the yard, from design through to fabrication and installation.

Calshot is based at James’ Wharf on the River Itchen in Southampton. Established in the 1870s as a railway ship repair depot, the site now operates as a fully equipped shipyard and production space.
The yard extends across more than 2.5 acres, with over 6,000 square metres of covered workshops and the last remaining operational dry dock in Southampton. It is structured to support complex, multi-disciplinary projects from concept through to installation.
The buildings have been restored progressively using salvaged materials and traditional methods. The workshops house engineering, fabrication and specialist trades working side by side within the yard.
