§ 02 — The Doctrine
Design,
engineered
TO OBSESSION
Three uncompromising commitments separate a NorthSea build from the catalogue. Every line, every surface, every byte — drawn with intent.
§ 01
Sculpted Form
Each silhouette begins in clay and CAD in parallel — a dialogue between hand and surface model until the proportion is right under any light.
Class-A surfacing
§ 02
Aero Verified
Splitters, diffusers, ducts — every aero surface is CFD-tuned and wind-tunnel verified before it ever touches a car.
Drag · Downforce · Cooling
§ 03
Digital Craft
Custom toolchains, generative geometry and bespoke control software. The car is hardware. The signature is the code behind it.
In-house R&D
§ 03 — Capabilities
A design
powerhouse.
From the first sketch to the final shakedown — exterior design, aerodynamic engineering, and the digital systems that bring a car to life. One studio. One signature.
Exterior Design

§ 04 — Divisions
Road. Sea.
Air.
One studio, three domains. The same doctrine — sculpted form, verified aero, digital craft — applied to whatever the brief demands.
Division I
Road
Bespoke bodykits and full builds for the world's most exacting marques.
See the fleet→
Division II
Sea
Stealth interceptors, super-tenders and mega-yachts, engineered from the keel up.
Enter Sea Division→
Division III
Air
Extreme aircraft — Mach 6 private jets, hydrogen VTOL heavy lifters, stealth rotorcraft.
