The Wall House I Sliding Glass Doors For Luxury Villa - IQ Glass International

Glass Bottom Swimming Pool and Double Height Automated Vertical Sash Window

This luxury home in Portugal has two stunning swimming pool areas, with one suspended above the other. Both areas benefit from expansive views of the surrounding gardens. The multiple sets of sliding glass doors for luxury villa featured, and each one granting uninterrupted views with ultra slim sightlines and allowing in an abundance of natural light throughout the home.  

One side of the large property presents a completely glazed façade, with a ground floor configuration of slim framed sliding doors and fixed structural glazing elements. The moving and fixed elements look perfectly symmetrical, presenting a consistent façade design.

For the outdoor areas of this luxury Portuguese home, a combination of bespoke glazing in Portugal and concrete building materials were used to give the structure a modern design with an industrial-style edge. The pool that is suspended across the ground floor pool was designed as a glass bottom swimming pool, supported by a steel structure. The swimming pool is situated within a double-height concrete structure, with arched designs and open walls to provide shelter whilst simultaneously enjoying the outdoors. The glass bottom of the pool provides shelter for the pool and surrounding area below without obstructing the flow of natural light.

The double height vertical sliding sash windows use specialist counterweighted technology and have a completely flush threshold to seamlessly merge the different areas when open, opening up the entire ground floor effortlessly.  The ground floor pool area is situated to the rear of the house, directly beyond the main house. A large, open-plan dining area and lounge create the perfect outdoor living experience for relaxing around the ground floor swimming pool.  

The glass ceiling houses the second swimming pool, where the homeowners can swim on the first floor. Due to the glass being the primary material in this innovative structure, someone swimming on the first floor can be seen from the ground floor terrace and pool area.

As the pool has a glass bottom, the load bearing of the glass had to be carefully calculated to ensure the right specification was used to withstand the pressure.
