Custom-built backyard submarines engineered with sheet iron and reinforced wood — affordable, innovative, and immersive.
We design and build budget-friendly backyard submarines using engineered sheet iron and reinforced wood structures. Website launching soon.
Our proprietary build process combines marine-grade sheet iron with structurally reinforced wood frameworks — delivering durability, buoyancy control, and an honest engineering aesthetic at a fraction of industry cost.
Hand-formed marine-grade iron plating, sealed and pressure-tested for shallow recreational depths.
Laminated hardwood ribs provide internal rigidity, vibration dampening, and a warm interior aesthetic.
Ballast, lighting, and viewport modules are pre-engineered for fast deployment in any backyard pond or basin.
Together we sketch your submarine — size, viewport configuration, interior layout, and depth profile.
Our Helsinki workshop fabricates the hull, frames the wood core, and assembles all systems by hand.
We deliver and install your submarine on-site, complete with operational training and safety briefing.
Compact backyard sub for shallow water exploration.
Mid-range explorer with extended viewport and dual-seat cabin.
Premium deep diver with reinforced hull and luxury interior finishings.
A fraction of traditional submarine costs without compromising on craft.
Hybrid iron-wood construction is our signature engineering principle.
The world's first dedicated backyard submarine builder.
