Interior Design Cost in Chiang Mai (2026)
Quick Answer
Estimated rangeInterior design costs in Chiang Mai are usually quoted either as a design fee, a percentage of project value, or a bundled package for a room or whole home. For a practical local budget, an estimated starting point is around THB 300–1,500 per square metre for design-only work, roughly THB 5,000–25,000 for a single-room concept package, and about 5%–15% of fit-out value for fuller design-and-project coordination services. Exact public Chiang Mai price lists are uncommon, so most figures below are clearly labelled estimates rather than confirmed tariffs.
Overview
In Chiang Mai, interior design pricing varies mainly by whether you need simple decoration advice, a full residential design package, or commercial design with drawings, specifications and site coordination. Unlike fixed-price consumer services, many designers in Thailand quote after a briefing because cost depends on floor area, design complexity, whether 3D renders are required, and whether the designer is also managing procurement and contractor coordination. For homes and condos, smaller jobs are often priced as a room package or by floor area, while larger house and hospitality projects may be priced as a percentage of the construction or fit-out budget. Chiang Mai generally sits below Bangkok for top-end design fees, but imported finishes, custom carpentry, and resort-style or boutique-hotel aesthetics can raise costs quickly. If you only need mood boards and layout guidance, expect the lower end of the range; if you need detailed joinery drawings, multiple revisions, site visits and supplier management, budget towards the upper end. Thailand does have a professional body for architects and an architectural licensing framework, but many interior design services are offered by studios, architects and design-build firms under different business models. Before hiring, ask what is included in the fee, how many revisions are allowed, whether site supervision is separate, and whether procurement mark-ups are charged on furniture and finishes.

Local Context
Quotes in Chiang Mai are usually given in Thai baht and may or may not include VAT, so check whether 7% VAT is included. Tipping is not generally built into interior design fees in Thailand, though some clients round up or provide a small gratuity for site staff on longer projects. Costs can vary significantly between Old City, Nimman, suburban housing estates and hospitality-heavy areas, especially where access, parking or condominium management rules affect site visits and deliveries.

Frequently Asked Questions
Is interior design in Chiang Mai cheaper than Bangkok?+
Often yes for standard residential work, especially local designer fees and labour coordination, but imported materials and custom furniture can narrow the difference.
Do interior designers in Chiang Mai charge by the hour?+
Some do for consultations or small advisory work, but fixed project fees, per-square-metre pricing and percentage-based fees are more common than pure hourly billing.
What is usually excluded from the design fee?+
Furniture purchases, contractor construction costs, custom joinery manufacture, permit-related work and repeated extra revisions are commonly excluded unless the contract states otherwise.
Do I need a licensed professional for interior design?+
For styling and general interior design, many studios operate without the service being sold strictly as architectural work. However, if the project involves structural changes, drawings requiring an architect, or regulated building work, use an appropriately licensed architect or engineer.
How can I find vetted interior designers in Chiang Mai?+
Start with recognised professional directories and established marketplaces. The Architect Council of Thailand can help verify licensed architects, while platforms such as DDproperty and local design directories can help you identify active firms to screen further.
