Designed by Iñaki Leite, this dwelling is located in the Arousa estuary, in the Northwest of Spain. It stands out for the use of recycled wood from the local fishing industry. It is also a reference in the area thanks to its energy efficiency and the careful integration of the building systems into the architectural design. It is no surprise that it has obtained the highest energy efficiency rating. In the interior, the use of the raw materials, natural reflexed light and bathrooms in frozen glass, create a relaxing effect. Another important feature of this house is the visual relationship of the different spaces, which contribute to the interaction of the occupants and the good spacious sensation. The wood used in this unique local fishing technique is exposed to the sea and coastal weather for over 25 years before being sent to recycling normally for vineyards or gardening. The use of this wood in architecture is pioneer. The beams have been treated and halved to produce two different textures. The outer part of the wood beam is rough and keeps the old texture. This is therefore used for the outer façade as a response to the urban scale. On the contrary, the wood used in the interiors, is the inside cut of the beam and is purposely used to provide more visual comfort and warmth.
