What Theon Design does
Theon Design is a UK-based, founder-owned bespoke restomod company that transforms Porsche 911 (964-series) donor cars into individualised, performance-enhanced vehicles. Founded in 2016 by automotive designer Adam Hawley and business/marketing specialist Lucinda Argy, the company operates from a purpose-built facility in Deddington, Oxfordshire, within the UK's 'Motorsport Valley' cluster, with a registered office in Abingdon.
The core product is a ground-up restoration and re-engineering of the 964 chassis: each donor is stripped to bare metal, digitised in 3D CAD, and rebuilt with carbon fibre bodywork, F1-derived carbon strengthening tubs, and an air-cooled flat-six engine (3.6L to 4.0L, 350-500+ bhp) managed by MoTeC electronics. The line consists of the Coupe, the open-top Targa, and the performance-focused Theon R (sub-1000kg, 500+ bhp). Every build is a one-to-one collaboration between the customer and founder Hawley, takes approximately 18 months and ~6,000 hours, and is priced from £420,000 (Coupe) and £430,000 (Targa), excluding donor car, shipping, and taxes.
The business model is direct, founder-led, and deliberately scarce: production is capped at roughly six commissions per year, sold exclusively through personal consultation with no dealer or reseller network, and serves a global clientele of high-net-worth collectors across the UK, Europe, the US (first delivery to Dallas in 2026), and Mexico. Theon is privately held with no external funding, generates revenue entirely from one-time commission sales, and relies on earned media and word-of-mouth rather than paid marketing.

Theon Design competitors and assessment
Company assessmentDirect peers
- Canepa: California-based collector car facility combining restoration, motorsport preparation and performance upgrades, with notable work on air-cooled Porsches. Comparable full-service approach to bespoke Porsche builds and similar price tier.
- Singer Vehicle Design: California-based restomod house that takes Porsche 911 (typically 964) donors and transforms them into bespoke, high-performance commissions. The category-defining player that Theon is consistently benchmarked against by press and customers, with a similar build-time, scarcity-driven model.
- DP Motorsport: Germany-based Porsche specialist producing classic 911 restomods (DP 964 RS, DP 935) with body, chassis and engine upgrades. Long-established European peer with similar donor-based bespoke model.
- Emory Motorsports: California-based bespoke Porsche builder known for hand-crafted 356 and 911 restomods with custom bodywork, interiors and powertrains. Long-standing direct peer in the air-cooled custom Porsche niche.
- Gunterwerks: California-based shop offering carbon-bodied 911 (993-based) restomods with bespoke engines and chassis tuning. Direct head-to-head competitor cited alongside Theon in Autoweek and Octane reviews as one of the leading air-cooled restomods.
- Tuthill Porsche: UK-based heritage Porsche specialist offering ground-up restorations, bespoke builds and racing preparation. Most direct UK geographic peer, with comparable 18-month bespoke commissions and pricing tier.
- Paul Stephens Automotive: UK-based specialist offering restored and reimagined classic Porsche 911s including carbon-body conversions and bespoke interiors. Direct geographic and product peer with comparable price points and craft positioning.
Broad incumbents
- RUF Automobile: Germany-based manufacturer of bespoke Porsche-derived sports cars (CTR, SCR, RGT) with VIN-recognized vehicle production, not just restomods. Overlaps on bespoke air-cooled performance positioning but operates a broader portfolio than Theon's 964-only focus.
