Last updated: 27 June 2026. This interior design cost guide was refreshed with clearer 2026 budgeting sections, room-wise planning, material notes and links to AS Design’s main interior and construction resources.
Interior design cost in Kathmandu depends on room size, design detail, material quality, carpenter/modular system, hardware, ceiling, lighting, paint, flooring and execution quality. A simple interior upgrade can be affordable, while premium kitchen, wardrobe, false ceiling and wall panel work can significantly increase the budget.

Room-Wise Budget Planning
- Living room: TV unit, sofa, ceiling, lights, paint/wall panel and curtains.
- Kitchen: cabinet, countertop, hardware, backsplash, sink, faucet and appliances.
- Bedroom: bed, wardrobe, study/vanity, lighting and wall finish.
- Bathroom: tiles, sanitary, vanity, mirror, lighting and waterproofing.
- Stair/lobby: railing, wall finish, lighting and ceiling treatment.
How to Control Interior Cost
- Finalize room-wise scope before taking quotations.
- Choose hardware based on use, not only looks.
- Use premium materials in visible/high-use areas and simpler materials elsewhere.
- Coordinate electrical points before furniture production.
- Prepare moodboard and material list before execution.
- Keep 10–15% contingency for changes and site issues.

Final Recommendation
Interior cost becomes easier to control when the scope is clear before work starts. Decide what must be custom-made, what can be bought ready-made, and where premium materials are actually worth it. A practical interior should balance beauty, durability, storage and maintenance.
