Villas & land
A curated portfolio in Koh Samui, sourced through partner agencies and filtered before you see it.
We verify the land, structure the ownership, model the returns and supervise the build — through a network we have worked with on the ground.
Koh Samui, north coast. Where most of our files start.
Thailand rewards the informed buyer and punishes the trusting one.
Not every document gives the same rights. Setbacks, slope limits and access issues only appear at the Land Office.
Nominee companies, leases with no renewal mechanism, entities with no substance. We build the version that survives scrutiny.
An owner abroad and a contractor with no accountability is the fastest way to lose a budget. We put eyes on the site.
Most never reach a client. That is the part of the job nobody invoices you for, and the reason the ones you do see are worth seeing.
Twelve months of sourcing across Koh Samui, rounded.
You deal with ARRTEA. We deal with the agencies, brokers, lawyers, contractors and financial advisors behind your project.

A curated portfolio in Koh Samui, sourced through partner agencies and filtered before you see it.

Title, zoning, access, boundaries and seller authority — checked at the Land Office, before any deposit.

Specialist lawyers set the ownership route: lease, company, condominium quota, building ownership.

ROI modelling on your specific site, and design decisions tested against profitability.

Vetted contractors, a written specification, and independent supervision at every payment stage.

Positioning, realistic yield, and day-to-day coordination for owners who live elsewhere.

Corporate structuring, licensing and large-scale development with recognised Thai developers.
Our contacts pull the title at the Land Office and compare what is registered with what is being sold. Half the time, that conversation ends there.

Lease, company, condominium quota or building ownership: the right route depends on your purpose and your exit, and it is set by a lawyer — never by a seller.

Tender, written specification, and payments released only against inspected work. An owner eight thousand kilometres away needs eyes, not photographs.

Indicative gross rental yields. Yours depends on location, standard and management — which is exactly what we model before you buy.
Gross, before management, maintenance and tax. Illustrative market ranges, not a forecast.
Each one ends with a decision you make with documents in hand.
Objective, budget, horizon — and whether you are buying to use, to rent or to develop.
A shortlist that fits the brief, with a comparative note on each option.
Title, zoning, access, restrictions and seller authority, before any deposit.
Lawyers set the ownership framework; we model the numbers alongside it.
Tender, specification and supervision with contractors whose record we can verify.
Rental positioning, management and reporting for owners who live elsewhere.
How long it actually takes





“We were three days from signing. ARRTEA pulled the title, found the access strip belonged to a third party, and saved us the whole project.”
