El Unico Mansion Spain House Plan: El Único (sometimes written El Unico) is not just another luxury villa on the Costa del Sol — it’s a statement piece: a purpose-built, curved ultra-luxury mansion in the exclusive gated community of La Zagaleta near Marbella. This guide breaks down everything a buyer, architect, designer or luxury-property writer needs to know: where it sits, how it’s designed, the floor plan logic, amenities and technical systems, sustainability and costs, and how to evaluate it as an investment.

Location & context: why La Zagaleta matters

El Único is located inside La Zagaleta, the ultra-exclusive residential resort and country club that consistently ranks among the most private and secure neighborhoods in Europe. La Zagaleta’s cachet—gated access, private golf courses, helicopter pads, and strict privacy rules—is a major part of El Único’s allure, giving owners not only spectacular natural views but also a high level of exclusivity. Listings and specialist luxury brokers emphasize that El Único’s positioning inside La Zagaleta is central to its valuation and lifestyle proposition.

La Zagaleta sits above Marbella on the hills between Benahavís and the coast, which means properties there, including El Único, enjoy panoramic Mediterranean views, immediate proximity to Marbella’s luxury hospitality scene, and the region’s mild climate — an important selling point for year-round living, second-home buyers, and rental returns. Real-estate dossiers for El Único consistently call out the sweeping sea vistas and mountain backdrops as core selling features.

Architectural concept & signature design elements

What makes El Único visually and technically exceptional is its curved, continuous geometry — the villa is promoted as “the first curved ultra-luxury villa in Marbella.” The architectural language favors sweeping concave/convex façades, large floor-to-ceiling glazing, and terraces that follow the building’s curvature so interior and exterior spaces flow seamlessly. This sculptural approach was created to harmonize the building with the hillside contours and to create panoramic sightlines from nearly every principal room.

Key architectural highlights frequently referenced in listings and editorial features:

• Curved main volume — the continuous form sets El Único apart from rectilinear luxury villas in the area and allows unique terrace geometries and circulation patterns.
• Double-height entrance and atrium with monumental glazing (reports mention a 7-metre high window in the entrance) that stages the interior arrival sequence.
• Large terraces and cantilevered overhangs that shade interiors while creating sheltered outdoor living areas — important for Mediterranean comfort and for the villa’s visual drama.

From an architectural-programming standpoint, the curvature is more than a gimmick: it drives how rooms are planned (fan-shaped suites, radial circulation), how structural loads are managed (curved slabs and cantilevers), and how mechanical and façade systems are integrated (custom curtain walls, bespoke sun-screening). Architects and builders flag that curved forms increase both design prestige and construction complexity — a tradeoff reflected in price and build time.

Floor plan & internal layout — reading the house plan

When people ask for the house plan of a property like El Único, they want to understand the functional zoning: how many bedrooms, levels, service areas, entertainment spaces, and terraces — and how these components interact. Public listings consistently describe El Único as an enormous multi-level residence organized around both social and private corridors, with a separate staff wing and extensive back-of-house facilities.

Typical layout and floor-plan features for El Único (synthesized from agent brochures and property descriptions):

• Plot and built area: the estate sits on a plot of around 8,000 m² with a built area reported between 2,200–3,300 m² depending on the source (some brokers list 2,200 m² built with 1,100 m² terraces, while others list up to 3,300 m² as a turnkey figure). The property therefore behaves like a small compound rather than a single, modest villa.
• Levels & circulation: El Único is reportedly arranged over multiple levels (often described as four floors) to step down the hillside. The main social floor includes the double-height entrance, lounge, main living room, formal dining area and the show-kitchen(s). Upper levels and mezzanines open to terraces and capture views. Lower levels contain entertainment and wellness amenities.
• Bedrooms & suites: publicly available listings typically advertise 8–10 bedrooms (many sources specify 9 bedrooms) — each with en-suite bathrooms, and a monumental master suite described in several listings as a private suite of extraordinary size (some sources state the master is ~180 m², with private terrace, dressing rooms and a designer bathroom). Separate staff accommodation (2-bed staff suite in some descriptions) keeps service circulation discreet.
• Indoor/outdoor flow: the house plan emphasizes outdoor living as much as the interior square footage: expansive terraces (broker PDFs and web pages list up to 1,100 m² of terrace area in some breakdowns) that wrap the building permit al fresco dining, lounging and pool connections.
• Back-of-house & garage: the estate includes large garages (8 car garage cited in the marketing materials), staff kitchen, deliveries zone and service access that preserve the property’s luxurious presentation while maintaining functional day-to-day operations.

Because of the villa’s radial geometry, many rooms are planned as sectors of a circle or wedge — an uncommon house-plan logic that rewards careful furniture planning, custom millwork and purpose-designed lighting. Expect bespoke joinery and curved millwork throughout the layout.

Amenities, entertainment & wellness — the experiential plan

El Único was created to be an entertainment machine as much as a home. Broker dossiers and property walk-throughs list a spectacular roster of leisure facilities that read more like a boutique resort than a private house. Some of the standout experiential elements found in marketing materials include:

• A 130-metre water slide that runs through parts of the entertainment complex and links outdoor play with indoor recreation.
• Full wellness circuit with a spa, steam room, sauna, and a heated indoor pool. The presence of both indoor and outdoor pools is emphasized across listings.
• Entertainment complex with a private cinema, bowling alley, games room, bar areas and social lounges — literally designed for hosting large groups and events.
• Sports & active amenities like a half-basketball court and space for fitness studios. Several listings highlight unusual inclusions for a private home, like an indoor basketball practice area.
• Roof top terrace & observation decks — marketing calls out a roof terrace (reported in some sources at ~500 m²) that serves as a spectacular party level and view platform.

These amenities create specific requirements in the house plan: dedicated structural support for water features, acoustic separation for the cinema and bowling alley, ventilation and dehumidification for the indoor pool and spa, and concealed logistics routes for service and maintenance. Agents stress that these systems and spaces are built to hotel-grade standards — another reason why El Único is positioned at the top tier of the Marbella market.

Technical systems, sustainability & materials

Today’s top-tier villas are judged as much by their technical intelligence as by marble and wood finishes. El Único’s marketing emphasizes both cutting-edge home-automation and renewable energy integration.

• Sustainability: some listings explicitly mention state-of-the-art solar and wind energy systems integrated into the estate (solar pv arrays and auxiliary renewable features have been cited in developer and broker write-ups), indicating a shift in prime luxury properties toward energy resilience and reduced operational carbon.
• Smart home & AV: El Único is marketed as a house with centralized smart-home systems controlling lighting, HVAC, shading, security, AV and circulation. For a property of this scale, integrated BMS (building-management-style controls) are essential for both comfort and energy efficiency.
• HAVC, humidity & pool technology: the indoor pool, spa and water features demand advanced humidity control, heat-recovery systems, and chemical management — all of which are highlighted in the specification sheets as being installed to high standards.
• Finishes & bespoke components: expect high-end brands and bespoke design touches: Gaggenau kitchen appliances, designer bathrooms with premium tiles, curated lighting and furniture packages — many listings list top appliance brands and couture interior design by specialist firms.

From an engineering perspective, the most challenging items are the curved curtain walls, cantilevered terraces, and the water slide integration — each requiring bespoke structural solutions and high-precision waterproofing. Developers of El Único emphasize that the build has been executed with premium contracting partners familiar with high-end resort standards.

Price, market position & buying considerations

Price & positioning: El Único is offered at a multi-million euro price point. Multiple luxury brokers and listings situate the asking price near €30,000,000, making it one of the most expensive private homes currently available in the Marbella/La Zagaleta market. This headline price reflects both the size of the estate (plot/build figures detailed above), the rarity of the architectural concept, and the extraordinary list of amenities.

When evaluating El Único, consider these buyer-level factors:

• Running & maintenance costs: a property with hotel-grade amenities (spa, indoor pools, water features) has high annual maintenance — pool & water feature servicing, energy costs (unless fully covered by renewables), landscaping for 8,000 m², staffing, and security. Expect ongoing operating costs well into six figures per year. Listings and advisors stress budgeting for maintenance when calculating ROI or long-term ownership.
• Insurance & liability: extensive recreational installations (water slide, sports courts) raise insurance premiums and require carefully documented safety and maintenance protocols for legal and liability reasons. Work with insurers who specialize in ultra-luxury estates.
• Resale & rental potential: El Único’s one-off design is a double-edged sword — it can outperform the market because of uniqueness, but it can also be more niche when reselling. For ultra-high-net-worth buyers seeking trophy assets, uniqueness is a strength. If you plan to rent it short-term, the villa’s scale and exclusivity position it as a high-earning short-let for special events, but zoning and community rules in La Zagaleta must be checked before any rental program.
• Due diligence: given the complexity, buyers should request full as-built drawings, structural reports, mechanical & electrical (M&E) specifications, guarantees/warranties for pools and water systems, and third-party energy performance certificates. Work with lawyers experienced in Spanish property law and La Zagaleta’s community statutes.
• Negotiation levers: while headline prices in this market are often firm, potential levers include transfer of bespoke furniture packages, timing of completion (if listed as turnkey vs. handed over), and inclusion of maintenance contracts or staff transition support. Brokers typically negotiate on inclusions rather than move the headline figure dramatically.

Styling the plan — interior design, landscaping & staging tips

If you’re the buyer, architect or agent preparing El Único for market or use, the house plan needs complementing with an interior and landscape concept that respects the curved architecture. Practical design tips:

• Curved furniture & joinery: use bespoke curved sofas, radial carpeting, and arc-fitting cabinetry to reinforce the architectural language. Avoid heavy rectilinear furniture in the principal radial rooms, which will clash with the flow. (This is a design best practice for curved volumes and appears in interior briefs affiliated with the project.)
• Landscape terraces that mirror the plan: terrace planting should follow the building contour to maintain sightlines to the sea; choose low-maintenance, Mediterranean drought-tolerant species to reduce irrigation costs across large plots.
• Lighting strategy: cinematic exterior lighting on the curvature dramatizes the form at night, while layered interior lighting (ambient + task + accent) emphasizes materials and art without competing with views. For such a flagship property, lighting design is often handled by a specialist practice.
• Staging for sale or rental: present the villa in both daytime (to show views and terrace flow) and twilight (to showcase the light design). Use lifestyle photography that communicates both privacy (security, gated access) and entertainment capability (spill-over from indoor to outdoor events). Many of the marketing pages for El Único use cinematic video tours for this reason.

Conclusion — who should buy El Único and why it’s unique

El Único is explicitly for buyers who want trophy architecture, maximum privacy, and resort-grade entertainment under one roof. It’s not a “value play” — it’s a lifestyle asset: a private resort with bespoke architecture that doubles as a marketable trophy. The house plan reflects that purpose: compartmentalized but flowing spaces, event-ready entertainment wings, and a master suite that reads like a private suite in an upscale hotel.

If you’re an investor or buyer:

• Expect €30M-level pricing, high ongoing costs, and exceptional resale marketing potential if executed correctly.
• Do technical due diligence: pool/water systems, curved facade warranties, and a detailed M&E review are non-negotiable.
• Work with experts in curved construction and bespoke joinery if you plan further customization — the geometry demands specialist skills.
