Koh Samui Construction Expertise That Protects Your Investment
Building in Koh Samui isn’t the same as mainland construction. Island conditions demand specialized knowledge in materials, scheduling, logistics, and site management. Our two decades on Samui mean we’ve learned what works—and what fails—in this unique tropical environment.
Climate Challenges
- Monsoon Season: We schedule concrete pours, envelope work, and finishes around November-December rainfall patterns.
- High Humidity: Material selection crucial for preventing mold, warping, and corrosion in 80%+ humidity.
- Salt Exposure: Coastal properties require corrosion-resistant fasteners, treated materials, and protective coatings.
- Intense UV: Exterior finishes must withstand year-round tropical sun without fading or degrading.
Island Logistics
- Material Transport: Ferry scheduling and storage planning essential for uninterrupted workflow.
- Site Access: Many premium sites require specialized equipment for steep, narrow roads.
- Local Resources: Strategic relationships with island suppliers reduce delays and costs.
- Skilled Labor: Established teams familiar with quality standards and tropical construction.

- Access road planning and construction

Koh Samui Construction FAQs
How long does it take to build a villa in Koh Samui?
Typical villa construction takes 12-14 months from permit approval to turnkey completion. This includes 8-12 weeks for design, 6-8 months for construction, and 2-3 months for finishes.
Do you handle building permits and approvals?
Yes, we manage the complete permit process, including building permits from Koh Samui Municipality, EIAs, and utility approvals.
Can you build during the monsoon season?
Yes, but we strategically schedule work. Foundation and structural framing proceed with protection, while envelope closure and finishes are avoided during heavy rainfall.
Do you use local materials or import from mainland Thailand?
We combine both. Structural materials (concrete, block) are sourced from reliable Samui suppliers. Premium finishes are often imported from Bangkok or abroad based on quality requirements.
What warranties do you provide?
10-year structural warranty; 5-year waterproofing warranty; 2-year MEP warranty; 1-year finishes warranty.
