RAVAL — PARK AND SKYLINE CONCEPT
2 October 2026

SCOPE
97.1 hectares of Raval’s urban core, using the published OpenStreetMap neighborhood boundary, clipped at latitude 41.3746 to exclude the port. This is a spatial concept, not adopted planning or a parcel survey. Most existing fabric outside the selected landmark precincts would be replaced.

LAND PROGRAM (rounded)
Public park network, including internal paths: 28.8 ha
New street rights of way: 20.6 ha
Retained landmark precincts: 9.1 ha
School, health and sports reserve sites: 3.7 ha
New building footprint: 14.3 ha
Other setbacks, courts and open ground: 20.5 ha
Areas calculated in UTM 31N. Residual open ground is not counted as public parkland. Civic capacity has not been demonstrated; these are reserved sites.

HOUSING BASELINE
Approximately 23,400 residential units, derived as 33,670 cadastral premises × 69.5% residential use from Barcelona Municipal Data Office’s 2023 Raval profile (2022 observations), reproduced at:
https://www.scribd.com/document/662490822/Raval-2023
This is a rounded historical proxy, not a verified 2026 dwelling census. Cadastral tax-account counts were not substituted for housing-unit counts.

PROPOSED CAPACITY
33 towers of 45–70 storeys, with 8-storey mixed-use frontages and separate 16-storey housing buildings. Tower floorplates range from 900 to 1,848 m². Six floors per tower are excluded from residential capacity for mechanical, amenities and other uses. Frontage buildings and separate housing blocks reserve two floors plus 15% of their remaining gross floor area for non-residential uses. Retained buildings and civic sites contribute zero counted new homes.

Modeled residential gross floor area: 3,661,608 m².
Base case: 3,661,608 × 80% usable-area efficiency ÷ 80 m² average usable apartment = about 36,600 homes.
Conservative case: 3,661,608 × 75% efficiency ÷ 90 m² = about 30,500 homes.

These are total new homes after redevelopment, not additional homes. Against the 23,400-unit historical proxy, the scenarios imply approximately +13,200 (+56%) and +7,100 (+30%) net homes. If current housing stock were 25,000 units, the increases would instead be about +46% and +22%.

DESIGN INTENT
A continuous central park connects the MACBA/CCCB area, the hospital precinct and Sant Pau del Camp, with branches toward the east and the Drassanes. Taller buildings cluster in the north and west; lower frontages and civic plots articulate the park edges. New local streets use a nominal 18 m right of way and approximately 95 m spacing where feasible. Walking and cycling routes cross the park. Street endpoints and access around retained campuses require further design.

RETAINED ANCHORS
Hospital de la Santa Creu ensemble, including Institut d’Estudis Catalans and nearby associated institutional buildings; Gran Teatre del Liceu; La Boqueria; Palau Güell; Sant Pau del Camp; Drassanes Reials; MACBA/CCCB and Casa de la Caritat ensemble; Betlem and Palau Moja; Sant Agustí Nou; Santa Mònica and Teatre Principal ensemble.
This selection is not a complete inventory of protected buildings or archaeology.

NEXT VALIDATION
Verify the current dwelling inventory and full heritage constraints. Develop representative apartment floors, cores and daylight layouts; assess winter shadows, wind and tower separation; test transport, utilities, schools and health capacity. Establish phasing that supplies replacement homes, affordable tenures and a right to return for existing residents before clearance. The model demonstrates floor-area capacity, not guaranteed delivery or planning permission.

CIVIC RESERVE DETAILS
The nine sites C01–C09 are selectable in the map and 3D model. Potential uses include a school, nursery, elder day-care centre, primary-care clinic, community centre, library or sports facilities. These are options, not final assignments. Each site's area is reserved land, not building floor area or verified service capacity.
