The concept

One villa. One story.

Nestled in a peaceful, slightly elevated setting, Casa Una is a private collection of luxury villas crafted for those who seek both an emotional retreat and a smart investment.

Inspired by the intimacy of Balinese resorts and the purity of contemporary architecture, the project introduces a concept still rare on the island: private villas designed to live a unique experience.

Each space is conceived to be personal, immersive and timeless — where design meets profitability.

The island

Koh Samui

Koh Samui is emerging as one of Thailand's most promising real estate markets, driven by sustained tourism growth, limited land supply and rising demand for premium villas.

New direct flights to hubs like Dubai and Bali, major infrastructure projects (the upcoming bridge to the mainland) and the presence of recognised international schools strengthen its long-term appeal.

Investing in Koh Samui today means positioning yourself early in a destination that is moving up-market.

The location

Chaweng, the #1 address

Chaweng is the true economic heart of the island, with fast access to the international airport, the most renowned beaches, high-end restaurants, beach clubs and shopping.

This centrality makes it the strongest area for short-term rental, with year-round demand from an international clientele.

The model is transparent: a fixed fee for general estate maintenance, plus a commission on rental income. The better the villa performs, the better the collaboration works for everyone.

The concierge service is optional — you retain full freedom of management.

Frequently asked questions

Everything you need to know before investing

Can a foreigner buy a villa in Thailand?

Yes, through a leasehold of 30 years, renewable twice (30+30+30) for a total of 90 years. This is the standard, legal and secure structure for foreign buyers in Koh Samui. Casa Una assists every buyer through the process.

Why invest in Chaweng rather than elsewhere on Koh Samui?

Chaweng is the economic heart of the island: international airport 10 minutes away, the most popular beaches, fine dining and beach clubs. This centrality drives constant year-round rental demand (average occupancy 75–85%) and offers the strongest resale potential.

What rental yield can I expect on a Casa Una villa?

Depending on occupancy and collection: 13.9% to 29.9% for a UNA Nest (1 bedroom, €140,000), 17.4% to 34.9% for a UNA Horizon (2 bedrooms, €166,000), 17.4% to 37.9% for a UNA Signature (4 bedrooms, €254,000). Figures are based on documented scenarios (65%, 75%, 85% occupancy).

What is the project timeline?

Construction starts July 2026, delivery expected Q4 2027 (12 to 18 months of construction). A furnishing and rental setup period of 4 to 8 weeks follows handover.

What are the payment terms?

Staggered plan tied to construction progress: 5% on reservation, 10% at contract signing, 20% at construction start, 30% phase 2, 30% phase 3, 5% on handover. You pay at the project's pace.

Is there a rental management service?

Yes, Casa Una offers an on-site concierge: check-in/check-out, booking management, dynamic pricing, full maintenance (cleaning, pool, garden). The service is optional and based on a fixed fee + commission. You keep the freedom to self-manage if you prefer.

What fees and taxes should I expect?

On purchase: transfer fees (~6.3% of price), VAT not applicable on leasehold. Ongoing: estate service fees (~€150/month), rental tax based on income, and rental management commission if you use the concierge. Casa Una provides a full breakdown before signing.

Do I need to be in Thailand to buy?

No. The reservation signing and most steps can be done remotely, with legalised power of attorney. An on-site visit is recommended (but not mandatory) before final signing. Casa Una organises French-speaking guided visits in Chaweng.

What are the advantages of buying off-plan versus an existing villa?

Preferential launch-phase pricing (up to 20-30% below expected resale value), choice of finishes, brand-new equipment, 10-year warranty, interest-free staggered payments. The capital gain potential at delivery is significant.

What is the difference between the three villa collections?

UNA Nest (1 bedroom, €140,000): for couples, solo travellers, premium short-term rental. UNA Horizon (2 bedrooms, €166,000): for families or shared investment, open views. UNA Signature (limited collection 4 bedrooms, €254,000): for owners seeking prestige and long-term patrimonial value.

How does Casa Una secure the investment?

Developer The Circle Samui, transparent structure, 10-year construction warranty, payments tied to actual construction progress (no upfront lock-up), on-site team during and after construction. All legal documents are verifiable before signing.
