Luxurious 'treehouse' on the beach

The designers were able to open up between two of the vertical portal frames to create a 4m wide window that – at the press of a button – could disappear upward into a cavity to leave the lower section of glass as the balustrade. This lower section of glass is frosted for complete privacy while at the touch of a button, the glass un-frosts and the bath's occupant experiences an uninterrupted view to the ocean.
