Alternative investments, smartly mastered.
Dunes Alternative Investments is a boutique practice helping private clients invest in what endures — prime property, wine funds, the freedom of the open sea and the reach of the skies, with full end to end support in terms of real estate advice, fund management and tax, legal and notary support on every transaction.
The practice
A small firm, by design, for clients who value discretion above all.
We do not chase trends. We acquire, structure and steward tangible assets with lasting value — and we do it for a deliberately limited number of relationships.

Real Estate
End-to-end acquisition, sale and advisory
From off-market villas and penthouses to completing the transaction, we guide clients through every step — acquisition, structuring, cross-border ownership, tax planning, legal review and notary coordination — across Dubai, Marbella, Monaco and Switzerland.

Art, Wine & Collectibles
Tangible assets of lasting provenance
Museum-grade art, investment-grade wine and rare collectibles — curated, authenticated and stewarded for both pleasure and long-term appreciation.

Luxury Boat Rental
The sea as an asset and an experience
Our curated fleet of motor yachts is available for charter across the Mediterranean and the Gulf — a tangible asset that delivers both yield and unforgettable days at sea.

Private Jet Rental
The world on your schedule
From short-haul hops within Europe to intercontinental journeys, we arrange private jet charter that matches your itinerary, privacy requirements and standards of service.
