We built this one to our own brief — the van we’d take ourselves.

Most of our work starts with a customer’s van and a list of what they want fitted. This one started with a blank Relay and a simple question: if nobody was watching the budget, how good could a genuinely liveable, genuinely off-grid camper be?

The answer is on this page. A long-wheelbase, high-roof Citroën Relay taken from empty panel van to a three-berth camper with its own power, heat, hot water, a proper kitchen and an internal shower — the systems that let you park up somewhere remote and stay there. It’s the standard everything else we build is measured against.

The same work on smaller jobs: battery, solar & 12V installs and electrical fault-finding.

Warm on a Lancashire morning

Truma heating and hot water throughout, so the van’s as usable in February as in July — cabin heat where you need it and hot water at the tap and the shower.

A kitchen, not a compromise

Hob, oven, fridge and a proper sink built into bespoke units, with a dining table and seating that work for real cooking and real meals — furniture cut and fitted in-house to suit the layout.

Sleeps three, seats three

The long-wheelbase L3H2 shell gives the room to carry three on belted travel seats and sleep three — a layout that holds a washroom, a kitchen and a bed without feeling squeezed.

Listed and sold on completion — proof that a van built properly, systems as carefully as the finish, holds its value and finds its owner.

The same work, on your van.

We built every system in this Relay ourselves — the electrics, the heating, the plumbing, the furniture. That’s the same work we do week in, week out on smaller jobs: a diesel heater, a leisure-battery or solar upgrade, a water system, an awning, or a fault that needs finding — or a full conversion like this one.
