Budget: 3.193.750



The 24 homes required are distributed on first, second, third and attic floor, so that 10 of them are two bedrooms, 2 of two adapted bedrooms, 10 of a bedroom, and 2 of three bedrooms. The ground floor is used for parking, common access areas and storage rooms, and two premises with direct access from Pere Matutes Noguera Avenue. The organization in plant of the set, generates an inner distributor that opens towards the views on the Punta D'Abaix, generating a communal terrace in each floor of houses. It is a place of meeting, of interaction between the neighbours, in which the boundaries between the public and the private are blurred, generating an additional external stay for each of them. The houses are oriented towards the coast and towards the interior, favouring cross ventilation. All of them are organized in service bands perpendicular to the façade, one including living-dining room and kitchen, and the other bedrooms and bathroom. They open to the outside through a large terrace that incorporates a gardener with native vegetation.



A construction is planned above ground, thus avoiding the excavation of the land and the production of waste derived from this operation. The proposal generates two elements of houses linked together by interior corridors that open onto a large interior garden. The structure and the external enclosures are built using prefabricated concrete panels made in Ibiza, thus reducing CO2 emissions both in its transport and in its installation. In this way, the final image of the building is shown honestly to citizens, avoiding the use of other materials or exterior coatings that cover their original appearance. The interior insulation of the houses is solved with panels of rock wool, with thickness between 12 and an air chamber in facades, and 30cm on the roof. The interior distribution of the houses is made by laminated wood panels, pre-cut in the workshop and placed on site. Inside they will be painted white, except in toilets and other technical rooms, where local ceramic tile will be used on walls and floors. The interior pavements are configured with laminated wood panels and local ceramic elements. The joinery, with breakage of thermal bridge, is raised in wood, with double glazing and thermal solar control. All of them incorporate a roll-up sun protection system.



To achieve the required level, class A, the initial configuration of the project in the plot, is completed with a series of passive measures related to the use of available local energy resources, as well as the responsible relationship with the surrounding natural environment. The cross ventilation in all homes, uses the Embat and Terral wind currents, to ensure an improvement of the conditions and the interior comfort of all of them. It is combined with the use of mobile solar protection joined to the terraces created by cantilevers on the facade. The use of plant species in all the proposed planters on the terraces, as well as in the interior garden, will reduce the thermal sensation of the whole. We opted for the inclusion of native species of low water consumption, both arboreal and shrubby. This is combined with the placement of a sheet of water in the garden that favours the circulation of air in the patio, reducing again the thermal sensation of the whole.
