Is a multifamily building behind to buildings in the town of Sant Feliu de Guíxols. Was build in 1970, more or less, is in good condition, but it hasn’t the buildability exhausted,neither has well distributed the placements. Firstly, I would like to make a diagnosis of the building and see if it is well structured. Then, I will set to do a redistribution of the floors to maximize space, currently there are only two floors of 200 m2 each, I think is excessive. Later, I will study the possibility of using the maximum regulatory level for the construction of the third floor where I would like to make two apartments.
