Building a House on Mallorca — Step-by-Step from Plot to Keys

This is the operational guide we wish we’d had as buyers ourselves. Nine phases, 18–36 months, written so you know what’s coming next at each stage.

Phase 0 — Before you buy the plot (2–8 weeks)

The most expensive mistakes in Mallorca construction happen at the moment of plot purchase. Things to check before signing:

• Catastral vs Registro — do they agree on boundaries, area, classification?
• Urbanistic classification — Urbano, Suelo Rústico Comú, Suelo Rústico Protegido, Núcleo Rural? Each has different building rights.
• Water and electricity — connected, or feasible to connect?
• Access — legal access via public road, or right-of-way through someone else’s parcel?
• Heritage flags — anything on the parcel or immediately adjacent that triggers patrimony review?

Have an architect run this review before you sign. The fee is small (typically €500–€2,000); the downside avoided is large.

Phase 1 — Plot purchase and post-purchase setup (4–8 weeks)

Notary, Registro inscription, payment of ITP (Impuesto sobre Transmisiones Patrimoniales — currently 8% on Mallorca for resales) or VAT (10% on new builds). You’ll also need a NIE (Número de Identidad de Extranjero) if you don’t have one — this can take 4–8 weeks if you’re not already in the Spanish system.

Phase 2 — Topographic survey + geotechnical (3–6 weeks)

Survey of the plot, geotechnical drilling and laboratory testing. These need to happen before serious design work — the topographic shows you what you’re really building on, and the geotechnical determines foundation strategy and ground-water risk. Typical combined cost: €2,000–€6,000.

Phase 3 — Concept + preliminary design (6–10 weeks)

Architectural conversations begin in earnest. Sketches, volumetric studies, room programmes, façade language exploration. This is also when major decisions like single vs two-storey, basement vs no basement, pool location, and orientation get finalised. By the end of this phase you should have a clear preliminary design that you and your architect both believe in.

Phase 4 — Proyecto Básico + permit submission (4–8 weeks)

The preliminary design gets developed into permit-grade documentation. Submission to the Ayuntamiento (or ECU). At this point the project enters a queue at the regulatory office — you do not control the speed from here. The architect handles all correspondence with authorities.

Phase 5 — Permit review (3–14 months, depending on route)

The longest waiting phase. Use this time productively: finalise material selections, interior design, kitchen and bathroom specifications, AV/smart-home strategy, landscape design. Most clients underestimate how much there is to decide and discover too late that they’re holding the project up.

Phase 6 — Proyecto de Ejecución (6–10 weeks, overlaps Phase 5)

Construction-grade drawings. Every wall section, every joinery detail, every mechanical layout, every finish specification. The Proyecto Básico is the “what we’re building”; the Proyecto de Ejecución is the “how, exactly”. This phase can largely run in parallel with permit review.

Phase 7 — Tender + contractor selection (4–8 weeks)

Bill of quantities goes out to 3–5 pre-qualified contractors. Bids return, get normalised, get compared. A choice is made, a contract is signed. The contract usually includes payment schedule (typically 5–8 milestone payments tied to construction progress), liquidated damages for delays, and clear scope definition. Boilerplate Spanish construction contracts are increasingly recognisable; we use a customised version.

Phase 8 — Construction (12–22 months)

Site works begin: clearance, excavation, foundations, structure, envelope, mechanical systems, finishes, pool, landscape. Weekly site meetings, monthly invoicing against bill of quantities, continuous quality control. A typical 300 m² villa in Sa Torre with mid-premium finishes runs 14–18 months of pure construction time, plus 1–2 months of preparation and 1–2 months of snagging.

Phase 9 — Final de Obra + hand-over (4–8 weeks)

The final certificate of completion (Final de Obra) is signed by the architect after final inspections. The owner applies for the Cédula de Habitabilidad (certificate of habitability — required to live in the house and to connect to utilities). The as-built version of the building is registered with the Catastro and Registro de la Propiedad. Snagging list is closed. Keys are handed over.

The realistic total

From plot purchase to keys: 18 months at the absolute fastest, 36 months as a planning estimate. Anyone promising you 12 months on a new-build villa with standard Mallorca regulatory paths is either oversimplifying or overpromising. We tell clients 24–30 months as the working assumption, and we work hard to be at the lower end of that range.
