Casa 103 is located in an elevated position in Ferragudo, a fishing village in the Algarve, Southern Portugal. A derelict two storey house with a storage area on the ground floor formerly occupied the site. The challenge was to create a contemporary and eco-friendly retreat which took full advantage of the river view. A physical barrier or ‘wall’ at street level ensures privacy.Visual connections with the village and river are strengthened by the inclusion of large openings in the facade. Several levels form the internal spaces and reflect the topography of the site. A range of sustainable measures allow the building to function in an energy efficient way. Locally sourced materials were specified to complement plain white walls. Ultramarino designed a custom made kitchen and a range of storage solutions to maintain the understated quality of the concept.
