One of the last frontline beachfront estates on the Costa del Sol - six villas and 42 residences on Estepona's New Golden Mile
Sierra Blanca by the Sea is a frontline beachfront estate on Estepona's New Golden Mile, set across a 33,346 m² coastal plot directly on Playa del Ángel. The development comprises a limited collection of six beachfront villas and 42 apartments and penthouses across five three-storey buildings — 48 residences in total, within a gated, low-density environment where all vehicle circulation is routed underground.
Beachfront land of this scale is no longer readily available on the Costa del Sol. A constraint shaped by geography, planning restrictions, and decades of accumulated coastal development means that a private frontline estate of this size, in this position, cannot be assembled or permitted in the same form today. The estate sits directly adjacent to the Senda Litoral coastal path, with immediate access to Playa del Ángel and frontage on the Mediterranean.
The project is developed by Sierra Blanca Estates and is currently at priority pre-registration stage. Ownership is structured as freehold under Spanish property law, available to all nationalities.
The estate is positioned so that the Mediterranean shapes the rhythm of daily life. Full-height glazing on sea-facing facades removes the boundary between interior and terrace, while outdoor living spaces are proportioned for dining, entertaining, and extended use throughout the year. At surface level, all vehicle movement is underground, leaving only gardens, pathways, and direct beach access.
Within the villas, double-height living volumes open to the shoreline. Basement spa levels include indoor pools, saunas, and home cinema spaces. Rooftop gardens give uninterrupted views of the Mediterranean and the coastline.
The defining characteristic of Sierra Blanca by the Sea is structural: it occupies one of the last significant private beachfront plots available in this corridor. This is not positioning — it is a function of supply. Coastal planning restrictions and decades of development on the Costa del Sol mean that a gated, vehicle-free frontline estate at this scale cannot be assembled here today.
Beachfront real estate on the Costa del Sol has demonstrated sustained resilience, supported by constrained supply and consistent international demand. Sierra Blanca by the Sea enters the market with characteristics that underpin long-term positioning: a constrained location, low-density planning, and a buyer profile drawn from Europe, the Middle East, and Latin America.
At approximately €12,500 per m² on initial release, pricing aligns with established ultra-prime benchmarks in the corridor. Marbella and Los Monteros comparables provide a market reference point, and the absence of comparable pipeline product supports pricing stability over time.
Sierra Blanca Estates is a Marbella-based developer with a track record in high-end residential projects across the Costa del Sol. The studio focuses on prime locations, architectural coherence, and long-term asset quality — a positioning consistent with the scale and specification of this project.
Sierra Blanca by the Sea is presented by AW Real Estate on a selective basis. Qualified enquiries receive direct access to floor plans, unit availability, orientations, and early pricing before general market release. Priority registrations are currently open.
The New Golden Mile is a coastal corridor running between Puerto Banús and Estepona's town centre, positioned as the next chapter of Costa del Sol ultra-prime residential development. Over the past decade it has undergone a quiet but sustained repositioning — lower density than central Marbella, a less crowded shoreline, and proximity to Marbella's infrastructure without its concentration have drawn increasingly discerning international buyers. The typical buyer profile is European, Middle Eastern, and Latin American — purchasers seeking direct beach access, privacy, and modern architectural quality within a well-connected coastal setting.
The immediate environment combines direct beach access with walkable proximity to beach clubs, marinas, and five-star hotel infrastructure. The New Golden Mile functions as a quieter residential corridor relative to central Marbella, with full lifestyle amenity within short reach and an established connection to Puerto Banús. Three private beach clubs — Laguna, Sublime Beach, and Trocadero — are accessible to residents of Sierra Blanca by the Sea directly.
Sierra Blanca by the Sea occupies one of the last large-scale frontline beachfront plots on the New Golden Mile. Coastal planning restrictions and decades of development on this coastline mean that a private, gated, vehicle-free estate of 33,346 m² in direct beachfront position cannot be assembled or permitted in this form today. The six beachfront villas occupy a separate category of scarcity within an already constrained market.
It is structural. The Costa del Sol's primary coastal strip is extensively developed, and planning controls on new beachfront construction are strict. A private estate of this scale — 33,346 m², low-rise, gated, with underground vehicle circulation — cannot be assembled at this address today. No equivalent pipeline product exists on the New Golden Mile. The six beachfront villas, with direct beach frontage and private spa basements, represent a finite asset with no replication path.
The estate is fully gated with controlled access. All vehicular circulation is routed underground, which means the estate surface is defined entirely by gardens, pathways, and beach — no surface roads, no passing traffic. This design creates a quiet, pedestrian environment that is unusual in a beachfront context, where road access and car parks typically compromise the frontage.
Within the estate: indoor spa, hammam, sauna, heated pool, fully equipped gym, outdoor pool, paddle court, children's pool, social lounge, and concierge services. Ownership includes resident access to three private beach clubs — Laguna, Sublime Beach, and Trocadero. The estate sits directly on Playa del Ángel and is adjacent to the Senda Litoral coastal path, with Estepona town centre 5-10 minutes by road.
At approximately €12,500 per m² on initial release, pricing is positioned within the established ultra-prime range for the New Golden Mile, with Marbella and Los Monteros comparables as reference points. The key constraint is supply: no equivalent frontline product is in the pipeline at this location. Constrained supply, sustained international demand across European, Middle Eastern, and Latin American buyer profiles, and the structural scarcity of the plot itself underpin long-term pricing stability.
Core Marbella land has become scarcer and significantly more expensive over the past decade, while the New Golden Mile offers comparable coastal infrastructure — beach clubs, marinas, five-star hotels — in a less concentrated environment. Lower density, a quieter shoreline, and proximity to Puerto Banús and Estepona's amenities have repositioned the corridor from secondary to credibly prime. Informed buyers are treating it as the coast's next chapter, with a lower established price ceiling and a quieter ownership environment.
The project is at priority pre-registration stage — the point at which preferred units, orientations, and early pricing are accessible before general release. With only 48 residences in total and six beachfront villas, access is sequenced and limited. Floor plans and unit availability are released directly through AW Real Estate upon pre-qualification. Priority registrations are currently open.
