Interior Design Cost in Thailand: What You Pay For
Separate design fees from build costs before you set an interior budget.
2026-04-03
Interior design cost in Thailand splits into two parts: the design fee and the build. Design alone is often 500 to 2,500 baht per square meter or 8 to 15 percent of the build. Turnkey fit-out typically runs 15,000 to 50,000 baht per square meter depending on whether the level is economy, standard, or premium.
Design fee vs build cost
The design fee pays for concept, drawings, material selection, and site supervision. The build cost covers demolition, systems, carpentry, finishes, and furniture. Some studios charge design separately, others fold it into a turnkey price. Always clarify which model a quote uses so you compare like with like.
Levels: economy, standard, premium
Turnkey rates rise with material and detail. Economy uses laminate and standard fittings, standard adds better built-ins and finishes, premium brings veneer, stone, custom lighting, and imported pieces. Knowing your target level early keeps the design realistic and avoids redrawing when the quote lands.
- Design fee: about 500 to 2,500 baht per sqm, or 8 to 15 percent of build
- Economy turnkey: about 15,000 to 20,000 baht per sqm
- Standard turnkey: about 20,000 to 30,000 baht per sqm
- Premium turnkey: about 30,000 to 50,000 baht per sqm and up
What sits outside the headline rate
Per-square-meter rates often exclude loose furniture, appliances, curtains, and decor, plus permits or juristic-person fees in condos. Building rules, work-hour limits, and lift bookings can add time and cost in Bangkok high-rises. Ask for an itemized scope so surprises do not appear mid-project.
How much does interior design cost in Thailand?
Design fees are commonly 500 to 2,500 baht per square meter or 8 to 15 percent of the build, while turnkey fit-out runs roughly 15,000 to 50,000 baht per square meter across economy, standard, and premium levels. The mix depends on your finishes and scope.
Is it cheaper to hire a designer or a contractor directly?
A contractor alone can be cheaper upfront but riskier on layout, material choices, and coordination. A designer adds a fee yet often saves money by avoiding costly mistakes and rework. For complex or premium projects, integrated design and build usually gives the best result.
