Full home renovation in Barcelona with real site control

A large share of full renovations in Barcelona are commissioned by owners who are not living here — often bought as an investment, or inherited. At this scale the Spanish specifics stop being paperwork details and start driving the programme.

The three documents that gate the job

• Comunicat previ or minor works licence: a like-for-like refit is a prior notification, but move structure, change the layout significantly or touch the façade and it becomes a licence with a technical project — that alone is 1–3 months before anyone can start
• Cèdula d’habitabilitat: the habitability certificate, mandatory to let the flat or connect utilities in a new owner’s name. A full renovation is the natural moment to renew it
• Butlletí elèctric: the electrical certificate. A rewired flat needs a new one, and without it the supply company will not raise your capacity or reconnect

Where the comunidad has a vote, and where it does not

Everything inside your four walls is yours to decide. The moment work touches a communal element — the soil stack, the façade, the roof, the risers on the landing, the load-bearing structure — it needs the comunidad de propietarios to agree, and cost may be shared through a derrama apportioned by each owner’s coeficiente de participación. The practical consequence for a remote owner: we identify at survey stage which items sit on the communal side, so a junta that meets once a quarter does not silently become the critical path in your programme.

How we replace your presence on site

• One named site manager from strip-out to handover, not a rotating contact
• A weekly written report with photographs, including everything that gets covered up: services in the wall, waterproofing, structural work
• An inspection hole opened and photographed before the price is fixed, so structural surprises are found while you can still decide
• No additional work carried out without your written approval — variations are quoted and agreed, never invoiced after the fact
• Payments released against certified milestones tied to work actually finished
• Access, waste removal and working hours coordinated directly with the building administrator

Budget for what the walls hide

In the Eixample, Gràcia and Ciutat Vella the floors are typically Catalan vaults on steel joists. Where the joist ends are corroded, structural reinforcement adds 8–15 % to the budget. If you are buying to renovate, hold that contingency back rather than spending it on finishes — it is the single most common reason a remote project overruns.
