Why this works
A process built for proper clarity and control
Most problems on island builds do not come from one mistake, but from a series of early decisions made without the right understanding. Land is not properly assessed, designs are applied from the wrong climate, legal requirements are unclear, and builders are chosen without proper scrutiny.
This process is designed to resolve those risks in the right order, whether you are based locally or overseas. Each stage builds on the last, so the project moves forward with clarity, control, and decisions grounded in how building actually works on the island.
01
2–4 WEEKS
Land viability
"Small changes in slope, wind, and orientation can completely change how a house performs on Samui.."
island insight
Land Viability Assessment
Before any design work begins, we walk the land with you. We assess orientation, topography, soil, access, building setbacks and legal limits, all clearly understood from the outset. You leave this stage with a clear picture of what can be built, where, and what constraints apply.
What we deliver
Site analysis report
Legal & zoning check with tessaban
Buildable area assessment
Initial constraints summary
Verbal cost band guidance
What we need from you
Land documents (chanote)
Site access for visit
Initial brief or vision
Honest budget range
Concept design
"On island builds, the way a house is lived in matters more than how it is arranged on plan.."
island insight
Shaping the design
We translate your brief and the site analysis into a complete architectural concept. Three rounds of revisions are included as standard, giving enough room to refine without endless drift. The concept emerges from how you'll live, what the land allows, and what makes a home feel inevitable in its setting.
What we deliver
Floor plans, elevations & sections
Basic 3D renders & design narrative
Up to 3 rounds of revisions
Initial cost band estimate
What we need from you
Detailed brief & priorities
Reference images and priorities
Sign-off at each revision stage
Honest budget confirmation
02
6–10 WEEKS
Construction documentation
"Clear drawings protect you. When everything is defined, there is no room for interpretation."
island insight
Construction Drawings and Documentation
The approved concept is developed into a complete construction drawing set. Every wall, opening, junction, and finish is clearly defined so the project can be priced and built without ambiguity. This is the information the builder prices from, builds from, and is held to. Weak documentation is one of the main causes of budget overruns on Thai island projects.
What we deliver
Full 2D construction drawings
Structural brief & engineer coordination
MEP layouts
Materials & finishes schedule
What we need from you
Final material selections
Sign-off on spec decisions
Any specific fittings or imports
03
8–12 WEEKS
Permits & Approvals
"Permits in Thailand are not just paperwork. They depend on relationships and timing. A builder promising fast approval is either overpromising or taking risks."
island insight
Permits and approvals
We manage every application your project requires, including building permits, structural approvals, and any environmental, coastal, or zoning requirements. This is where foreign buyers trying to handle the process themselves often lose months. We understand how the system works, who to deal with, and the order things need to happen in.
What we deliver
Building permit submission (Tessaban)
Structural engineer sign-off
Environmental clearance (where required)
All follow-ups & resubmissions
What we need from you
Simple villa permit: 6–10 weeks
Site access for survey
Coastal or hillside site: 10–16 weeks
Commercial or resort: 12–20 weeks
04
2–4 MONTHS
Tendering & builder selection
"The cheapest quote is rarely the right one. Builders who underbid often recover costs later, once you are already committed."
island insight
Builder selection and cost review
With permits approved and documentation complete, the project can be sent to a shortlist of suitable builders you wish to consider. Each quote is reviewed against the Bill of Quantities, along with their track record and insurance. We provide a clear, independent assessment so you can make an informed decision.
What we manage
Detailed Bill of Quantities (BOQ)
Tender document pack
Quote review & normalisation
Reference checks on past work
Contract drafting & review
Payment schedule negotiation
red flags we watch for
Unrealistically low quotes
No liability insurance
Demand for front-loaded payments
Missing or unclear BOQ line items
No recent completed references
05
4–6 WEEKS
Construction oversight
"Projects without proper oversight tend to run into problems. Regular supervision keeps quality, cost, and progress aligned."
island insight
Site supervision and quality control
We visit site regularly, and unannounced where needed. We review quality at each stage, approve or withhold payments based on verified progress, manage variations in writing, and keep you informed with clear reports wherever you are in the world. Our role is to protect you by identifying issues early, before they become costly.
What we do on site
Scheduled milestone inspections
Quality sign-off at every stage
Payment approvals to the builder
Variation management (written)
Sub-contractor coordination
Photographic site reports
What you receive
Monthly written site reports
Photo & video updates
Scheduled video calls
Transparent payment approvals
06
6–12 MONTHS
Handover & beyond
"Handover is not the end. The first year of use reveals how the building performs in real conditions. Ongoing support during this period matters.."
island insight
Handover and completion
Before final payment is released, we carry out a full snagging inspection. Every issue is recorded, tracked, and signed off before completion. We then assemble your final documentation pack, including as built drawings, warranties, supplier contacts, and maintenance guidance. Where appropriate, we can also introduce trusted villa management for ongoing care.
What we deliver at handover
Full snagging inspection report
As-built construction drawings in PDF format
All product warranties
Materials & finishes record
Maintenance guide
Supplier contact directory
Post-handover support
Introductions to villa management
90-day defects liaison with builder
Anniversary-year walkthrough
Design support for future changes
07
