Interior Price per Square Meter: How to Read It

Interior work is often quoted per square meter because it lets you compare projects quickly, but the rate only means something once you know the scope. A 20,000 baht per square meter quote with premium finishes and one with basic laminate describe very different jobs, so always read what sits inside the number.

What a per-sqm rate typically covers

A turnkey per-square-meter figure usually bundles demolition, electrical and plumbing changes, ceilings, wall and floor finishes, built-in carpentry, painting, and basic lighting. What it often excludes is loose furniture, appliances, curtains, and decor. The line between included and extra is where quotes quietly diverge.

• Usually included: demolition, MEP changes, ceilings, finishes, built-ins, paint
• Often extra: loose furniture, appliances, curtains, decor
• Sometimes extra: design fee, permits, condo juristic fees

Why rates vary so much

Finish level is the biggest swing: laminate versus veneer, tile versus stone, standard versus imported fittings. Layout changes, moving wet areas, and structural or MEP work also raise the rate. Small units carry higher per-meter costs because fixed items like kitchens and bathrooms are spread over less area.

Compare quotes fairly

Never judge on the per-meter number alone. Ask each studio for the same scope, material schedule, and inclusion list, then compare. A slightly higher rate with clear specs and supervision often costs less overall than a cheap number that adds extras and rework as the project runs.
