Watch this full transformation from an empty shipping container into a hidden luxury underground room built directly beneath a backyard pond.
This satisfying build shows the complete container conversion process — from preparing the container structure and installing a wooden floor foundation grid, to adding mineral wool insulation, plywood flooring and wall panels, and creating a stunning glass ceiling panel beneath the pond above. The result is a one-of-a-kind hidden space with moving water reflections dancing across the interior.
Inside, the container is finished with cozy lounge area with a wall-mounted TV and L-shaped sofa.
If you love secret rooms, bunker builds, hidden container homes, underground spaces, luxury tiny houses, and satisfying construction timelapses, this project is for you.
