In truth, the upper floor is designed around a central outdoor patio which is the same size as the ground floor below it, and is planned around a "grid of four modules per side," as the architects describe it. The result is that all rooms on this floor are exposed to the outdoors on all four sides, bringing in the light and fresh, eucalyptus-scented air.

Geometric perfection also plays a leading role in the ground floor. Although it too is divided into "found equal quadrants," the north quadrant is "cut back" creating a harmonious entrance into the house from the lagoon and garden, leading up a flight of heavy concrete stairs - inventively built into the corner - to the upper floor's outdoor patio.  

Inside, the same sparse and heavily minimal design elements develop, with a long hallway wrapping around the upper courtyard and leading to the rooms off of it. This is further mirrored in the façade which was created by thin wood formwork boards that were used during the casting of the concrete, infusing the building's veneer with a coarse "woodsy" texture as well as a seemingly weather-beaten black patina.

All in all, Guna House is the type of architectural specimen that causes double takes as viewers wonder at the genius behind its balance, as well as at the simplicity sheathing its complex design.
