Belding B&A in La Reserva de Sotogrande: Antares, Alnair, Aldebarán, Altair, Atria & Unique

Walk through La Reserva de Sotogrande today and you’ll notice a quiet pattern repeating on the hillsides: sculptural, single-owner villas that seem to grow out of the slope rather than sit on top of it. Six of them share the same architect and the same design philosophy — and, if you look closely, the same naming convention. Antares, Alnair, Aldebarán, Altair and Atria are all named after stars. Villa Unique is the exception that proves the rule, and the most literally-named of the six.
All six are the work of Belding B&A, a residential developer that has made La Reserva its showcase for what it calls “excellence” and “innovation” — and, increasingly, a name that buyers researching this part of Sotogrande are searching for directly. Two of the six, Villa Aldebarán and Villa Altair, are currently available through Open Frontiers. The other four give a clear picture of where the rest of this collection is heading.
Who is Belding B&A
Belding B&A (marketed as Belding B&A + Unique) describes itself as more than a developer — a studio built around “a passion for detail, an unwavering commitment to quality and a constant quest for perfection.” Its two stated pillars are excellence and quality, and its tagline — “excellence is our compass and innovation is our horizon” — is a fair summary of the six villas below: contemporary volumes, natural materials (stone, wood, white stucco), and a consistent basement-level wellness program of gyms, spas, cinema rooms and wine cellars across the whole collection.
The Six Villas
Villa Aldebarán

The first of the collection to reach the market through Open Frontiers, Villa Aldebarán sits on a 2,635 m² plot with 921 m² built, sculpted into a steep slope so the architecture responds to the terrain rather than fighting it. Six bedrooms, eight bathrooms, a central double-height living space, twin reflecting pools at the entrance and an infinity pool that reads as a continuation of the horizon. We’ve covered it in full in Villa Aldebarán Sotogrande: Where Architecture Meets the Landscape.
- Price: €9,950,000
- Plot / built: 2,635 m² / 921 m²
- Bedrooms / bathrooms: 6 / 8
- Status: Available through Open Frontiers
Villa Altair

Our newest listing, Villa Altair occupies the highest point of La Reserva de Sotogrande, on a 2,052 m² plot with 1,123 m² built — newly completed and never lived in. Belding B&A splits the main floor into two wings, one for daytime living and one angled toward the sea, with a sixth bedroom and guest house on the lower level. Underfloor heating, solar panels, an infinity pool and a heated indoor pool complete a home built for year-round use rather than a summer showcase.
- Price: €7,950,000
- Plot / built: 2,052 m² / 1,123 m²
- Bedrooms / bathrooms: 6 / 8
- Status: Newly completed, available through Open Frontiers
Villa Antares
On a 3,491 m² hillside plot overlooking one of La Reserva’s golf courses, Villa Antares is the largest of the six at 2,860 m² built — seven bedrooms and eight bathrooms arranged around a circular, naturally-lit wine cellar and a basement “leisure sanctuary” with its own spa, gym, cinema and virtual golf room. A sculptural pedestrian path and double-height entrance set up what Belding B&A describes as a panorama of sea, sky and fairway from the moment you arrive.
- Plot / built: 3,491 m² / 2,860 m²
- Bedrooms / bathrooms: 7 / 8
Villa Alnair
Villa Alnair steps down a hillside plot of 2,624 m² across two levels plus basement, linked by a glazed, timber-louvred walkway around a central courtyard. Living areas face east to the sea; every bedroom faces south, toward the Strait of Gibraltar — on a clear day, Africa is visible from the terrace. Six bedrooms, eight bathrooms, 1,731 m² built, with native olive, jacaranda and mastic planting worked into the landscaping.
- Plot / built: 2,624 m² / 1,731 m²
- Bedrooms / bathrooms: 6 / 8
Villa Atria
Built to answer a genuinely difficult plot — steep, irregular, 2,045 m² — Villa Atria uses cantilevered volumes that appear to hang over the slope rather than rest on it. Double-height dining opens to a terrace and pool on the ground floor; five en-suite bedrooms sit above; wellness and staff facilities occupy the lower level, lit through an internal courtyard. 1,620 m² built, six bedrooms, six bathrooms.
- Plot / built: 2,045 m² / 1,620 m²
- Bedrooms / bathrooms: 6 / 6
Villa Unique
The smallest and most restrained of the six, Villa Unique commits to single-floor living on an 1,816 m² plot — soaring ceilings, full-height glazing and a signature canopy structure instead of a second storey. Five bedrooms, six bathrooms, 861 m² built, with a neutral palette of coastal whites and natural stone and a central pool anchoring the plan. It’s the one villa in the collection where the name describes the layout rather than the sky.
- Plot / built: 1,816 m² / 861 m²
- Bedrooms / bathrooms: 5 / 6
The Collection at a Glance
Living in La Reserva de Sotogrande
Every one of these six villas sits inside the same gated enclave: wide, low-density plots around the golf course and clubhouse of La Reserva Club, with beach club access, international schools nearby, and the privacy and security that Sotogrande buyers specifically come here for. It’s also, at this point, one of the clearest concentrations of contemporary architecture anywhere in the south of Cádiz — six villas from one studio, each solving the same brief (steep terrain, sea views, wellness at basement level) in a genuinely different way.
Why This Matters If You’re Buying
For buyers comparing new-build villas in Sotogrande, this collection is a useful yardstick. Plot sizes here run from roughly 1,800 m² to 3,500 m², built areas from 860 m² to 2,860 m², and every villa carries the same non-negotiables: a spa-and-cinema basement, native landscaping, energy-efficient systems, and an architectural idea rather than a generic floor plan repeated with a different address. Villa Aldebarán and Villa Altair are the two currently on the market — one an established masterplan piece at just under €10 million, the other a brand-new, never-lived-in home just under €8 million. If Antares, Alnair, Atria or Unique come to market, or if you want to see the two available villas in person, Open Frontiers is the team to call.
