Who says a classic 911 should be saved for the weekend?
Every Theon Design commission is created around how its owner wants to drive it. That might mean a favourite road on a Sunday morning, a journey across Europe, or simply making the everyday commute something to look forward to.

With contemporary comfort, carefully developed engineering and a driving experience that makes even the shortest journey rewarding, there's every reason to enjoy your car as often as you like.

After all, the more you drive it, the more you'll enjoy it.

Colour is one of the most personal decisions in any Theon Design commission.

Here’s an early glimpse of our latest Coupé in build, finished in a striking shade of yellow. And from what we can share so far, the rest of the specification is every bit as individual.

There’s much more to reveal in the coming weeks.

Have a particular colour in mind for your own commission? We’d love to hear your ideas.

Fighter jet technology comes to Theon.
Our first Theon commission with carbon ceramic brakes is in build. Developed in the aerospace industry, these composite material brakes are designed specifically for Theon to deliver unrivalled stopping power every time you press the pedal.

Driving is about having full control - from our bespoke flat-six engines, purpose-built suspension, and now carbon ceramic brakes. Every Theon rewards its driver.

Our latest Targa may be finished in a beautiful bespoke Aquamarine, but when you strip away the colour, the purity of a Theon Design commission speaks for itself.

Our cars offer an opportunity for true individual expression, whilst still guided by the same philosophy – respect the original, refine with purpose and create something that will look and feel just as special decades from now.

Vibrant details in the city.
Completed in June 2026, this UK RHD 4.0 Coupe commission takes a particularly focused approach to the air-cooled 911, pairing Crayon Grey with Lizard Green accents for a specification that feels purposeful, contemporary and distinctly urban.

Understated from a distance. Full of character up close.
