Luxury Villa for Sale in Altea Sierra: Elite Estate with Guest House and Double Plot Development Potential

This premium luxury villa for sale in Altea Sierra represents one of the most significant real estate opportunities on the Costa Blanca. Merging classic Mediterranean architecture with high-end contemporary interior design, this sprawling 920 m² mansion offers unrivaled privacy, panoramic views of the Bay of Altea and the Sierra Helada, and elite lifestyle infrastructure.

Crucially, the estate is set across two urban plots totaling 2,440 m², offering the rare commercial or personal flexibility to construct an entirely separate secondary residence of up to 500 m² on the property grounds.

🏗️ Multi-Level Architecture & Sophisticated Interiors

Extensively refurbished using premier materials and timeless finishes, the main residence features an optimized multi-level layout designed to balance grand entertaining spaces with absolute family privacy.

Main Living Level

• Grand Entrance: A magnificent wooden door opens into a soaring reception hall, establishing an immediate sense of scale.
• Open-Concept Core: Features an expansive salon anchored by a contemporary fireplace, a formal dining area, and a designer kitchen equipped with a premium island and integrated appliances.
• Indoor-Outdoor Flow: Floor-to-ceiling windows line the entire level, bathing the space in natural light and framing the exceptional views of the Mediterranean Sea.
• Accommodations: Two large bedrooms, each featuring luxurious en-suite bathrooms.

Lower Living Level

Accessed via an ornate interior staircase, this bright floor operates as a secondary social hub or an autonomous guest zone:

• Includes a secondary spacious lounge, a dedicated TV media room, an additional dining space, and a fully functional open-plan kitchen.
• Housekeeping amenities—including a large laundry room and major storage facilities—are discreetly positioned on this level.

Ground & Wellness Level

• Includes a dedicated fitness gym area, utility management rooms, and extensive additional storage.
• Features a secure, integrated closed garage with capacity for three vehicles.

🌴 The Moroccan-Inspired Guest House & Exotic Gardens

The outdoor footprint of this estate is designed to resemble a private boutique resort, surrounded by enclosed, perfectly manicured grounds featuring mature Mediterranean flora.

• The Guest House: Completely separate from the main mansion, this independent villa boasts an authentic Moroccan architectural design. It features a private garden, independent climate control, a connected security alarm, fiber-optic internet, and cable TV—offering elite comfort for visitors or staff.
• The Grounds: Winding stone paths lead through vibrant flower beds to an exotic fish pond, creating pockets of absolute tranquility across the 2,440 m² estate.

📐 Double Plot Advantage: A Rare Investment Feature

The defining asset of this property is its land configuration. Because the estate sits on two independent urban plots, the new owner secures immediate development potential that is heavily restricted elsewhere in the Sierra de Altea:

• Build a Second Villa: You retain the legal right to build an additional 500 m² independent villa—ideal for extended family, a guest estate, or a high-value resale project.
• Unmatched Privacy Buffer: Alternatively, keeping the plot as a manicured garden guarantees that no future construction can ever compromise your views or your privacy.

Brokla Pro-Tip: Finding a 2,400+ m² plot in the Sierra de Altea that is already segregated into two urban parcels is incredibly rare today. Altea’s strict building regulations mean getting a new plot of this scale with 500 m² of extra buildable volume is almost impossible. Even if you don’t build a second home, that second plot represents a massive financial safety net that appreciates independently.
