Marine Hills Fase 1
Project lifecycle
Marine Hills Fase 1, in context.
Marine Hills Phase 1 is a gated residential development of apartments, penthouses and semi-detached villas in Selwo, on the western edge of Estepona — positioned within what is broadly referred to as the Golden Triangle between Puerto Banús, Estepona and Benahavís. Construction began in January 2025, with completion expected between September 2026 and June 2027.
Of the 119 residences across nine blocks in this phase, 95 have already sold, leaving just 24 available — a sell-through rate that speaks clearly to demand at this price point. Built areas range from 123 m² to 502 m², with plots on the semi-detached villas reaching 547 m². Pricing runs from €585,000 to €1,638,000. The communal offer is notably broad: three pools including a heated pool, two jacuzzis, a spa, gym, paddle court and co-working space, set within landscaped Mediterranean gardens.
For buyers who have missed the first wave, the remaining 24 units represent the last opportunity within this phase.

The off-plan discount, stage by stage
Off-plan entry typically offers the largest pricing headroom at the earliest stages. The advantage narrows as construction progresses — at completion the unit is priced at market. Marine Hills Fase 1 currently sits in the Under construction band.
Construction is live, the programme is defined, and the project's own sales record — 95 of 119 units sold — provides genuine market validation. The Selwo area's median resale price per square metre sits at approximately €3,709 (, current), and per-square-metre pricing at Marine Hills reflects a premium consistent with new-build specification and the amenity package on offer. With just 24 units left in Phase 1, the scarcity argument is not theoretical — it is arithmetical.
Why buyers reserve at this stage
Personalisation window
Reserving during the Under construction phase gives buyers genuine input into layout, finishes and basement use ahead of handover — a window that closes as the build advances.
Scarcity and specification
24 of 119 units remain. The plot sizes, orientation and amenity package on this scheme are not easily replicated in the immediate resale stock.
Risk-managed entry
Spanish new-build buyers are protected by staged payments held under bank guarantee, ten-year structural warranty and full licence review. Roccabox brokers all of this through regulated counsel.
The premium, contextualised
Useful context — not a substitute for unit-level valuation. Pricing data cross-referenced against live Costa del Sol market signals.
Marine Hills Fase 1 is not priced against average Estepona resale stock. It is a premium new-build product with the specification, plot quality and amenity package that the broader resale market typically does not match. At €4,756 per built m² the relevant question is whether the premium is justified against comparable new-build completions — not whether it beats the area's median of €3,364/m².

What every unit receives
Living in Estepona
Selwo sits in the transitional belt between Estepona and San Pedro de Alcántara, placing residents within reach of both Estepona's old town — with its pedestrianised lanes, weekly markets and harbour — and the commercial and leisure infrastructure of Puerto Banús, roughly 15 minutes by road. The immediate surroundings are defined by low-density hillside topography and open countryside views, with the coast accessible in under ten minutes. Selwo Aventura, the wildlife park adjacent to the development, gives the area a distinctive edge for families. The broader corridor offers some of the Costa del Sol's most recognised golf courses, international schools and private medical facilities, all within a short drive.

Understand the full picture
Spanish purchases involve taxes and fees that catch first-time international buyers off-guard. We surface every figure that matters.
Typical off-plan payment schedule
Spanish new-build purchases are typically paid in three staged instalments, with every euro held under bank guarantee until completion.
Total cost of ownership

Investment outlook

Residency planning for non-EU buyers
Spain's property-based Golden Visa route closed to new applicants on 3 April 2025. Non-EU buyers acquiring property at this value still have residency routes — non-lucrative visa, digital-nomad visa, and case-specific options — depending on circumstances. We introduce regulated immigration counsel before any commitment.
