Poble Sec and Sant Antoni are 1920s–60s buildings, active communities and turnkey demand. Logistics, acoustics and permits — not a brochure neighbourhood.
Typical range is 950–1,600 €/m² excluding construction VAT. A 70–90 m² flat usually sits between €70,000 and €130,000 depending on services, acoustics and whether partitions need reinforcing. City context: Barcelona prices 2026.
Visit, survey of services, itemised budget, permit and build with a digital panel. If there is an interior designer, we join as the executing contractor. Related: Gràcia (similar old-stock buildings) and Barcelona permits 2026.
If structure and façade stay untouched, a prior communication or minor works filing is often enough. Redistribution or common elements raise the procedure. We define it from the actual building, not a template.
In most flats yes, unless it is a load-bearing wall or a beam is required. That is decided on a site visit, not in a form.
10–16 weeks for 70–90 m², depending on the community and the scope of services.
