Bespoke Landaulet Exterior Coachbuild Conversion Package
Transform your luxury SUV platform into an open-top coachbuilt masterpiece with the custom Landaulet conversion package by Kubay Design. Engineered specifically for modern donor platforms produced from 2018 onward, this comprehensive workshop conversion combines an extended rear body structure, portal-axle suspension, and a manual mechanical soft top into one fully re-engineered open-air configuration.
Standard enclosed SUV bodywork offers great daily utility, but upgrading to a coachbuilt open-top layout creates an exclusive, collector-grade vehicle silhouette. This conversion alters the vehicle at both a structural and visual level, featuring:
- Extended rear body section with custom wide-body fender arches.
- Manual mechanical folding roof assembly requiring no complex hydraulic systems.
- Portal-axle suspension upgrade providing a lifted stance and correct geometry.
- Full exterior structural re-engineering and bodywork finishing.
- Professional on-site workshop labor handled by qualified specialists.
Designed for private builds, limited collector runs, and brand demonstration vehicles, this conversion preserves structural rigidity while delivering unmatched open-air luxury. Discover complementary exterior components in our Shop or view completed builds in Our Projects.
Portal Axle Engineering & Manual Folding Soft Top Architecture
Executing a coachbuild-level conversion demands combining advanced chassis geometry with dependable mechanical operation. The Kubay Design engineering team utilizes portal axles to elevate ground clearance and maintain proper axle geometry alongside a simplified, ultra-reliable manual folding roof mechanism.
Key Coachbuild Features
Creating a high-end open-top off-road build requires specialized manufacturing and structural standards, which our workshop package delivers through focused engineering:
- Portal-axle suspension integration: delivers incredible ground clearance, wide-track stability, and aggressive off-road stance.
- Pure mechanical folding roof: engineered with a manual latching mechanism that operates seamlessly without electronic sensors or hydraulic pumps.
- Wide fender arch extension: custom-molded fender flares balance the lifted portal-axle proportions and wider track width.
Generational Compatibility & Vehicle Delivery Requirements
While this coachbuild conversion targets modern donor platforms produced from 2018 onward, verifying your vehicle’s physical condition and delivering the donor chassis to our workshop before starting your executive open-top Landaulet coachbuild project is essential:
- Modern donor platforms (2018–2024): full structural transformation including portal axles, rear body extension, and soft top fitting.
- Updated donor platforms (2025+): compatible with updated chassis mounting points and modern electronic architectures.
Workshop delivery requirement: this service is not a ship-to-customer parts kit. The donor vehicle must be delivered directly to our workshop facility for complete structural re-engineering and hand-crafted bodywork installation. Optional interior upgrades, glass partition walls, and custom roof linings can be commissioned separately. Please contact our team via our Contacts page to review vehicle compatibility and schedule your build.
