Floating among trees,

Bilbao (Spain)
300 m2
A54 Arquitectos

Sitting in the tree tops to obtain the best views and sunlight, this floating building is constructed with natural materials such as slate, wood and stone. Most notably, the exterior of the building is cladded with CUPACLAD® 201 Vanguard.

This house has been designed by Sustainable Energy & Housing architects to become a Net Zero Energy Building (NZEB).

A contemporary dwelling representing a creative challenge, but both architecturally stunning and functional at the same time.

This contemporary 3 storey building is in total harmony with nature. The thermal energy which is necessary to make it self-sufficient is generated in the home itself, combining aerothermic and a photovoltaic system with battery.

Besides this, the architects wanted it to blend with the natural landscapes while improving the efficiency of the dwelling. That’s the reason why they decided to install CUPACLAD® 201 Vanguard.

“Our project is inspired by organic architecture: we wanted it to embrace nature, looking for the least impact. That is why we chose natural materials. CUPA PIZARRAS slate was the perfect material for this project: it is 100% natural, rainproof, efficient and provides a great aesthetic value.“
says Pedro Rebollar, Sustainable Energy & Housing CEO.


The CUPACLAD® 201 VANGUARD rainscreen cladding system stands out due to its stainless steel clips, which are slightly visible at the bottom, contrasting with our natural slate. The result is sustainable cladding with a modern touch.
