Interior Design Cost per Square Metre in Bangkok
Interior design priced per square metre, from design-only to full turnkey delivery, finished with styling and photography.
Interior design in Bangkok is priced per square metre: roughly 1,500 to 3,500 THB per sqm for design only, and 18,000 to 50,000 THB per sqm for turnkey work covering design, materials, built-in furniture, and installation. Final cost depends on style, material grade, and floor area. HONGHAUS quotes transparent, stage-by-stage pricing.
Design-only suits owners who already have a contractor: you receive 3D visuals, floor plans, and a material spec to build from. Turnkey means we handle everything from design to move-in-ready handover, controlling budget and quality under one contract.
The per-sqm rate rises with material grade, the complexity of built-in joinery, and style (modern luxury uses more material and craftsmanship than minimal). We break the price down by category before any work begins.

Questions, answered
How is interior design priced per square metre?
Design-only runs about 1,500 to 3,500 THB per sqm, while turnkey work including materials and construction starts around 18,000 THB per sqm. The real figure depends on style, material grade, and how much built-in joinery is involved. We calculate from the unit's actual usable area.
Is turnkey pricing very different for a condo versus a house?
Fairly different. A whole house usually carries a higher per-sqm rate than a condo because it has more varied spaces, more building services, and often higher-grade materials and bespoke work. Turnkey condos sit at 18,000 to 35,000 THB per sqm, while houses start around 25,000 THB per sqm.
Does the price include furniture and decor?
Turnkey packages include built-in furniture and core works. Loose furniture, decor, and styling are itemised separately in the quotation. You can choose full styling with photography, or have us cover only the construction and built-in scope.
