This beach house couldn’t get any closer to the water even if it wanted to. Located near Cape Town, South Africa, this house was designed to create an extraordinary living experience.
The home was built using a minimal steel framed box with a hull-shaped roof, clad in hardwood.
All of the external walls are made up of frameless sliding folding glass doors, with privacy and security added with slatted hardwood shutters, which open hydraulically to become verandas when open and a continuous secure screen when closed.
The living and sleeping areas are separated by sliding ash clad doors which slide away during daytime hours to create a single large living space.

I notice they didn’t show the safe room vault, automatic weapons rack, minefield map, emergency helipad, or the angry Rottweiler kennel.
I would consider those to be essential supporting features.
