Theon Design is a UK-based Porsche specialist focused on reengineering classic air-cooled 911 models into modern, bespoke creations.

Each car begins as an original 911 and is completely rebuilt with a focus on precision, lightweight construction, and refined usability — while preserving the character that defines the air-cooled era.

Rather than restoring cars to original specification, Theon reimagines them. Every build is tailored to the individual owner, combining traditional craftsmanship with modern engineering to create a driving experience that feels both authentic and contemporary.

From suspension and drivetrain to interior and finishing, every detail is carefully considered and executed to an exceptional standard.

Each car is built to order.
Each car is unique.
