Koh Samui Property Due Diligence
Koh Samui Property Due Diligence
Buying land or a villa in Koh Samui without proper property due diligence is risky. Slope, zoning, coastal setback rules, utilities and drainage can all limit what you can really build – even if the view looks perfect on the first visit.
Archi Studio and our construction arm Ancra help international buyers, funds and developers verify a site before they commit, so every Baht you invest is aligned with what is actually legal and buildable.
We combine on-the-ground experience in Koh Samui with architectural, engineering and construction knowledge:
– Check if you can build what you plan
– Identify hidden risks early (waterways, drainage, neighbour walls)
– Map out a realistic development strategy and budget
Our goal is simple: no surprises after you sign.

Make sure your Samui land can legally become the villa or resort you imagine.
Our team looks at more than just the title deed. We analyse how regulations, topography and infrastructure interact on your specific plot:
– Is the land in a waterway or drainage path?
– Are there existing retaining walls or neighbour walls to respect?
– Will you need special piling or slope stabilisation to build safely?
This is the kind of insight you don’t get from a quick site visit or an agent brochure.
We then translate that analysis into clear next steps:
– What you can build now
– What may be possible with permits or design adjustments
– What is too risky or not recommended
So you can negotiate price, structure the deal, or walk away – with confidence.

FAQ
Common questions about Koh Samui property due diligence
Do I really need due diligence before buying land in Koh Samui?
Yes. Koh Samui has strict environmental, height, slope and coastal rules. A plot that looks ideal in photos may be heavily restricted once you check altitude, slope percentage, beach setback and green-area requirements. Due diligence gives you the real buildable picture before you transfer any money.
Can you check if there is electricity, water and road access?
Absolutely. We review power lines, water supply options and legal access (public road or registered servitude). We also flag if you’ll likely need your own well, pump room or upgraded transformer, so you can factor this into budget and negotiations.
What if the land is in a natural waterway or drainage line?
If the land sits in a natural waterway or low-point drainage basin, you risk flooding, erosion and disputes with neighbours. We identify these risks early using topographic data, site walks and storm-water logic. In some cases we can design around it; in others, we may recommend not proceeding.
Can you estimate construction cost as part of due diligence?
Yes. While this is not a full BOQ, we provide high-level construction cost ranges per sqm based on your intended spec (standard luxury vs. ultra high end) and site difficulty (hillside vs flat land). This helps you check if the land price plus build cost still matches your investment strategy.
Do you also handle design, permits and full construction?
Yes. After due diligence, many clients stay with us for concept design, masterplanning, permitting and full construction. Because our design and build teams were involved from the first analysis, we move faster and avoid rework.
How do we start the due diligence process?
Step one is simple: send us the Chanote copy, Google Maps pin and any concept brief. We’ll review and propose a due diligence scope, fee and timeline. Once confirmed, we begin the Scan → Study → Strategy workflow and schedule your follow-up call to walk through the findings.
