Whether you have recently received the keys to a new flat or are planning a complete makeover for your current space, one critical question always comes up early: "How long will my interior renovation actually take?"

While television makeovers suggest full flat transformations can happen in just a few days, realistic architectural design and execution require a structured, phased approach. In Dhaka, overall project duration depends on apartment size (e.g., a compact 1,200 sqft flat vs. a spacious 2,200+ sqft duplex), material selections, custom millwork, and site coordination.

1. Renovation Timelines by Project Scope

Defining your overall scope early helps set realistic expectations before site work begins:

• Cosmetic Touch-Up (3 to 5 Weeks): Ideal for minor visual upgrades, including fresh wall paint, vertical fluted paneling, surface light updates, window treatments, and loose furniture placement.
• Partial Interior Fit-Out (6 to 10 Weeks): Focuses on high-impact zones like a modular kitchen makeover, custom living room TV feature units, dinner wagons, and bedroom wardrobe setups.
• Full Turnkey Interior Renovation (3 to 5 Months): Designed for complete apartment makeovers. Includes spatial replanning, full false ceiling integration, electrical and plumbing rewiring, custom HDF/Plywood cabinetry, and complete surface styling.

2. Phase-by-Phase Timeline Breakdown

To prevent mid-project pauses and maintain uncompromised finishing quality, a professional interior project moves through five organized execution phases:

• Phase 1: Spatial Planning & 3D Visualization (2 to 4 Weeks): On-site measurement, functional layout planning, client requirement mapping, detailed 3D visual renderings, and material sampling. Locking in exact design details on paper prevents costly structural alterations or delays once construction begins.
• Phase 2: Core Sourcing & Off-Site Millwork (2 to 3 Weeks): Procuring tested core boards (Gorjan Plywood, HDMR, or MDF), ordering anti-scratch laminates and soft-close hardware, and initiating off-site wood cutting. Preparing custom cabinetry carcasses in advance allows for cleaner, faster assembly on the active site.
• Phase 3: Civil Works, Utility & Ceiling Rough-Ins (3 to 5 Weeks): Wall adjustments (if required), electrical conduit routing, plumbing updates for kitchens and baths, and gypsum false ceiling framework setup. Concealed mechanical, electrical, and plumbing updates demand precise technical execution and adequate drying time.
• Phase 4: Custom Joinery, Tiling & On-Site Fit-Out (4 to 8 Weeks): Floor tile laying, full-height wardrobe shutter fitting, quartz countertop installation, CNC decorative panel mounting, and wall trim work. Multi-trade execution must follow a strict sequence where wet work and ceiling work precede delicate wood joinery.
• Phase 5: Surface Finishing, Lighting & Staging (2 to 3 Weeks): Duco paint or PU lacquer finishing, mounting cove and magnetic track lights, deep cleaning, furniture staging, and final quality inspections. Fine detailing, surface curing, and meticulous quality checks ensure long-lasting durability before handover.

3. Key Factors That Cause Unexpected Delays

Understanding common roadblocks helps keep your project running smoothly:

• Mid-Project Design Modifications: Changing cabinet layouts, wall textures, or material choices mid-way pauses site work and alters material orders.
• Housing Society & Building Rules: Many residential areas (such as Gulshan, Banani, Dhanmondi, or DOHS) enforce strict working-hour limits, lift usage rules, and weekend noise restrictions.
• Uncoordinated Independent Contractors: Managing separate carpenters, painters, and electricians often creates scheduling conflicts and accountability gaps.
• Delayed Material Decisions: Postponing choices for tiles, sanitary fittings, or laminate shades halts subsequent installation steps.

4. How BOQ Planning Keeps Projects on Schedule

A detailed Bill of Quantities (BOQ) clearly outlines exact material specifications, brand origins, hardware quantities, and fixed execution schedules upfront. Partnering with a professional interior architecture firm like Excellence Architecture provides transparent BOQ tracking and complete project management guarantees seamless trade coordination, zero unexpected mid-project price hikes, and a predictable, on-time handover date.

Conclusion

A successful flat renovation is not built on guesswork—it relies on thorough architectural planning, clear timelines, and disciplined site management.
