This is a project developed under the rules of eco-design UNE-EN 14006, through traditional systems and innovative construction. In this case CLT wood panels were used as the outer enclosure of the facade and the structure is made of reinforced concrete. The wavy polymer concrete panels are fixed to the top of the ventilated façade. The timber warmth also has been used to design the interior spaces. The natural lighting also plays an important role in this design thanks to the interior courtyards and the curtain wall of the back façade.
