Urban land in Martinique Ateneu multi-family building

Corner Lot in Martinica Ateneu 1. Location and Land Classification The plot is located in one of the most established and highly valued residential areas of Cerdanyola del Vallès, the Martinica / Ateneu sector. The land is classified as Zona d’ordenació en edificació aïllada, Clau 20a, specifically within Subzone III (20a/7). Unlike other single-family subzones, Clau 20a/7 allows multi-family use in a detached-building typology. 2. Summary Table of Planning Parameters According to the detailed regulations for urban land in Subzone III, the following limits apply: *Plot Application (705 m²)Plot Area- 705 m². Net Buildability Index 0.75 m²st/m²s => 0.528 m²st/m²s (proportionally reduced) = 372.77 m² *Maximum Site Coverage. 30% =>211.50 m² *Regulatory Height. 9.15 meters =>9.15 meters *Number of Storeys GF + 2 upper floors => GF + 2 upper floors at the rear and on the façade GF +1 upper floor * Maximum Number of DwellingsModule of 80 m² of floor area =>4 Dwellings (rounded down) 3. Justification of Buildability and Density Given that the net area of the plot (705 m²) is below the minimum plot size established for Subzone III (1,000 m²), the net buildability index of 0.75 m²st/m²s must be reduced in the same proportion as the area relative to the required minimum.Buildable Floor Area Total Buildable Floor Area: This results in a maximum of 372.24 m² of above-ground built area.Residential Density: The maximum number of dwellings is calculated by dividing the maximum buildable floor area by the 80 m² module, allowing the development of an exclusive scheme of 4 residential units. 4. Siting and Massing The project must comply with the minimum setbacks to boundaries defined for Subzone III, ensuring a detached building with high privacy and environmental quality: Front Setback (Street): 4 meters. Side Setback: 6 meters. Rear Setback: 8 meters. Additionally, ancillary structures (such as garages or external storage rooms) are permitted with a maximum coverage of 4% of the plot and a height of 3.30 meters, counted within the overall maximum site coverage. Basement area is excluded from the buildability calculation, allowing optimization of space for private parking. 5. Asset PotentialThe 20a/7 regulations at this location represent a unique opportunity for the development of a low-density “Boutique Building.” The possibility of delivering 4 high-end homes in a garden-city setting, with a Ground Floor plus two upper floors and large private green areas, positions this plot as a high-return asset with strong demand in the Martinica market.
