One of the most common questions clients ask when considering an interior design project is: how much will it cost? It is also one of the most difficult questions to answer without context, because interior design costs vary enormously depending on the type of project, the quality of specification, the size of the space, and the complexity of the design. This complete interior design cost guide for Bangladesh provides honest, practical cost benchmarks for every major project type — so you can plan your budget with realistic expectations before you begin.
How Interior Design Costs Are Structured
Total interior design project costs typically comprise four components: design fees (the cost of the design service itself — typically 8–15% of total project cost); furniture, fixtures and equipment (FF&E — often the largest single component at 35–45% of total); construction and built-in elements (flooring, partitions, joinery, lighting, MEP works — typically 30–40%); and contingency (always budget 8–12% for the unexpected).
All cost benchmarks below are total project costs per square foot including all four components, based on mid-range quality specifications in Dhaka. Budget specifications reduce these figures by 35–50%; premium and luxury specifications increase them by 50–150%+.

What Drives Costs Up — and Down
Factors That Increase Cost
- Custom-designed furniture versus catalogue products
- Imported versus locally sourced materials
- Complex architectural details (curved elements, feature joinery, specialist finishes)
- High-specification lighting design with bespoke fixtures
- Advanced technology integration (smart systems, premium AV)
- Phased works with the space occupied during construction
Factors That Reduce Cost (Without Reducing Quality)
- Good early brief that minimises design changes later
- Early procurement that avoids delays and premium pricing for rushed orders
- Flexible timing that avoids peak contractor availability periods
- Retaining existing elements that work (rather than replacing everything)
- Integrated design-build appointment that eliminates coordination costs
Getting an Accurate Quote
The most reliable cost figures come from a detailed design and specification — not from early-stage cost guides like this one. A reputable designer will not provide a firm quote from a brief conversation; they will develop a design to a sufficient level of detail that accurate procurement pricing can be obtained. House De Arch provides detailed cost plans at concept stage (indicative range), design development stage (accurate estimate within 10–15%), and final specification stage (fixed price under our EPC contracts).
