The Commission

Bosham, the bespoke Defender D90, invites you to imagine the feeling of commanding a legend that’s been completely reimagined for the present day.

Bosham exudes classic Defender charisma, but beneath its iconic exterior lies the precision and comfort that set Helderburg builds apart. Each Defender D90 starts as a canvas for transformation, stripped down and handcrafted back to life, paying homage to heritage while integrating innovative upgrades.

From the flawless, deep finish of the paint to the snug yet spacious interior, every facet is tailored to elevate the classics from utilitarian to utterly desirable. With modern performance enhancements and bespoke comfort features, Bosham is designed to stand out—whether weaving through city streets or cruising scenic backroads. It’s a vehicle that gathers admirers everywhere it’s seen and offers an ownership experience that extends well beyond simply driving.

The photos on this page are more than images; they’re gateways to the craftsmanship and devotion poured into every build. Owning a Helderburg isn’t just about having a Defender; it’s about indulging in timeless design, relishing the drive, and becoming part of a passionate community that values authenticity, individuality, and legacy.

Every line above is the result of upgrades engineered in-house, found in no other custom or restomod Defender in the world.

Four Styles, One Custom Process

A Helderburg is not one look. It is your own.

Bosham is one direction. Every Helderburg is custom, designed around the owner rather than chosen from a catalogue, and most commissions draw from one or two of these four. The expedition build is the one most people picture first. It is only the beginning of what a custom Defender by Helderburg can be.

Why a Helderburg Drives Differently

The difference is not cosmetic alone.

The architecture itself has been re-engineered. If you want the full picture of what is under a Helderburg before you speak to Paul, two doorways.

The Twelve Systems

Bosham carries twelve proprietary Helderburg systems, found in no other restored, custom or restomod Defender. The drivetrain on the original block. A suspension with the body roll engineered out, widened at the chassis, not with spacers. A cabin built for the eighth hour, not the first.

Three Approaches. Only one is a Helderburg.

A classic Defender can be restored, restomodded, or re-engineered. A restomod replaces the body and drops in a GM V8 crate motor, no longer numbers matching. Respectfully, a kit car. A Helderburg keeps the original chassis and block, and re-engineers everything else.

Past Commissions

Every one built once. None of them again.

Bosham is one of many. Each Helderburg is built for a single owner, then never repeated. A few of the commissions that came before.
