About Theon Design

Theon Design has a simple goal: to create the ultimate air-cooled Porsche 911. Rooted in a deep respect for Porsche heritage and driven by an uncompromising pursuit of engineering excellence, Theon blends the analogue soul of the classic 911 with the precision, refinement and usability expected of a modern performance car.

Based in the heart of the UK’s renowned “Motorsport Valley” in Oxfordshire, Theon Design brings together a highly specialised team of experts spanning automotive design, engineering, powertrain development, chassis tuning, trim craftsmanship and precision manufacturing. Every commission is approached with OEM-level precision, combining cutting-edge digital design and manufacturing techniques with painstaking hand-built craftsmanship.

Founded in 2016 by automotive designer Adam Hawley and business and marketing specialist Lucinda Argy, Theon Design was born from a shared vision to reinterpret the iconic 911 without compromising the essence that made it legendary. Together, Hawley and Argy have built a company that combines world-class automotive design and engineering with a highly personal, client-focused approach, establishing Theon as one of the most respected names in the modern restomod world.

Adam Hawley brings more than two decades of experience from leading global manufacturers including BMW, Jaguar and Lotus, while Lucinda Argy’s expertise in business and brand strategy has helped shape Theon’s international reputation and bespoke customer experience. Their complementary skillsets underpin the company’s philosophy: engineering-led, design-driven and entirely focused on creating deeply personal driver’s cars.

Theon Design evolved from Hawley’s personal ambition to build what he believed was the perfect Porsche 911 — a car that captured the purity, tactility and emotional engagement of an air-cooled classic, while integrating modern levels of comfort, drivability, reliability and performance. The original prototype received immediate acclaim from enthusiasts and collectors alike, leading to the creation of Theon Design.

Today, every Theon commission begins with the iconic Porsche 964-generation 911 before undergoing a comprehensive ground-up transformation. Each donor car is stripped to its bare shell, digitally scanned, strengthened and meticulously reengineered before being rebuilt using lightweight materials, bespoke detailing and carefully developed mechanical upgrades. The result is a uniquely tailored machine that preserves the unmistakable character of the classic 911 while elevating every aspect of the driving experience.

Attention to Detail

Theon Design has developed considerably in the ensuing years, and now operates out of a state-of-the-art facility in Oxfordshire, nestled in the heart of the UK’s ‘Motorsport Valley’.

For every bespoke commission, the expert team holds steadfast to its ‘Purity of Purpose’ ethos; state-of-the-art digital design techniques are blended with traditional hand-craftsmanship, distilling the character of the air-cooled 911, and elevating every part of the experience.

The goal is to evolve and enhance a classic Porsche, applying an OEM-like approach with Computer-Aided Design (CAD) and manufacture to ensure the highest possible quality and finish.

Design Ethos

Theon Design honours Porsche’s heritage and engineering ethos, with a focus on lightweight construction and enhanced performance, as well as ultra-precise and engaging driving dynamics.

The ‘Purity of Purpose’ approach results in what Theon Design calls ‘OEM+’; each bespoke, individually tailored commission blends the highest possible quality, finish and overall aesthetics, with a perfectly optimised, emotive 911 driving experience.
