The UNA Signature is a four-bedroom architectural residence offered as a limited collection, with panoramic perspectives and a design inspired by international resorts, designed for owners seeking prestige and a long-term legacy asset. It is part of Casa Una Residence, a new off-plan development by The Circle Samui in Chaweng, Koh Samui. It is offered from 9,900,000 THB (≈ €261,000), excluding the furniture pack.

At Casa Una, the UNA Signature costs 9,900,000 THB (≈ €261,000), plus a furniture pack of 1,000,000 THB (≈ €26,000), for a total investment of 10,900,000 THB (≈ €287,000). Prices are set in Thai baht; the euro equivalent is indicative, at the rate of 5 June 2026 (€1 ≈ 38 THB). Payment is staged and interest-free, tied to construction progress: 5% on reservation, 10% at contract signing, 20% at construction start, 30% at phase 2, 30% at phase 3 and 5% on handover.

For a UNA Signature at Casa Una, the land lease rent is 12,500 THB a month (initial rate, +5% every 5 years), co-ownership fees are 8,000–8,500 THB a month (pool, garden, gym, spa, pest control, waste collection) and water is 250 THB a month, i.e. 20,750–21,250 THB in fixed monthly costs. Electricity is not included: it is metered and billed at the public PEA tariff, according to the villa's consumption. Rental income tax, property tax and insurance come on top of these amounts.

According to Casa Una's estimates, a UNA Signature rented between 65% (237 nights at 12,000 THB) and 88% of the year (321 nights at 12,000 THB) would produce an estimated net income of about €42,000 to €59,200 a year, roughly €3,500 to €4,930 a month. This is after the Airbnb/Booking commission (15%), rental management and concierge (15%), land lease rent, co-ownership fees, water and a maintenance and furniture reserve (5%). These are estimates, not guaranteed, before electricity, rental income tax, property tax and insurance.

Yes: foreign buyers acquire a Casa Una villa such as the UNA Signature through a lease registered at the Land Office (leasehold) for up to 30 years (Section 540 of the Thai Civil and Commercial Code); renewal options are contractual and only the first 30-year term is legally certain. Having the contract reviewed by an independent Thai lawyer before signing is recommended. On delivery you can live in the villa, rent it out, or combine both; the on-site concierge (fixed fee + commission) can run the rental, but it remains optional.

Casa Una's timeline sets the construction start in July 2026 and delivery of the UNA Signature in Q4 2027 (12 to 18 months of construction), followed by 4 to 8 weeks of furnishing and rental setup.
