Plot with license for two homes in San Francesc

Urban plot of 417m2, located in Sant Francesc, capital of the island of Formentera, with great proximity to the main services. A few meters away there are restaurants, educational centers, supermarkets, shops and the island's hospital.
The project, with a building plan already approved by the city council, is made up of:
Two semi-detached houses of 125m² each, with three bedrooms; with basement, ground floor, first floor and covered floor. The construction of these two houses will be the responsibility of the buyer, the sale price only includes the land plus the project approved by the city council.
The 68m2 basement will house the technical room and can also be used as a storage room or a games room. On the ground floor, measuring 61m2, there will be the day rooms. Once we enter the house, through a previous porch, we will find a distributor space where we will access the main rooms, all of them related to each other, giving a feeling of spaciousness and comfort. Both the staircase and the living room, dining room and kitchen are designed as very open spaces and we would end up with a small toilet.
On the first floor, measuring 65m2, there will be three bedrooms, one of them with an en-suite bathroom and the other two sharing a bathroom. On the covered floor, it is planned to create a pleasant space for a solarium, which could be completed with a jacuzzi, for example. In addition, it will have two parking spaces, one for each home, located in the free space of the plot not assigned to the garden.
The distribution of these two semi-detached homes is very similar, so everything that refers to one can be moved to the other.
Fantastic opportunity.
