Almost every office fit-out conversation starts with cost. The second question — and often the more painful one — is time. Your lease commencement date is fixed, your rent-free period is ticking, and your team has already been told which Monday they are moving in. So how long does an office fit-out actually take in India?
The honest answer for a typical corporate office is 10 to 16 weeks from signed drawings to handover, with another 3 to 6 weeks of design and approvals before that. Below is what actually consumes those weeks, where projects slip, and how to compress the schedule without paying for it in defects.
The realistic office fit-out timeline, stage by stage
These durations assume a 10,000–25,000 sq ft warm shell office in a Grade A building in a metro like Ahmedabad, Bengaluru, Pune or Mumbai. Smaller spaces compress; larger or bare shell spaces stretch.
Weeks 0–3: Briefing, space planning and concept design
This stage decides how well the next four months go. Headcount projections, meeting-room ratios, workstation density, storage, pantry load and future expansion all get locked here. Rushing it is the single most expensive mistake in a fit-out, because every change after tender re-prices the job. Good space planning at this stage typically pays for itself in the area you avoid renting.
Weeks 3–6: Detailed design, MEP coordination and BOQ
Ceiling plans, HVAC layouts, electrical loads, fire detection and suppression, data cabling and plumbing all have to agree with one another before anyone lifts a tool. Uncoordinated MEP drawings are the number one cause of on-site rework — a diffuser and a sprinkler competing for the same 600mm tile costs days, not minutes. Running project and MEP consultancy in parallel with interior detailing, rather than after it, removes most of that risk.
Weeks 4–7: Landlord approvals and statutory clearances
This runs alongside design and is the stage most schedules underestimate. Building management approval for fit-out drawings, structural and load sign-offs, fire NOC where applicable, lift and material movement slots, and society or park working-hour restrictions can each add a week if submitted late. Submit landlord drawings the moment the ceiling and MEP layouts are frozen — not after procurement.
Weeks 6–10: Procurement and long-lead items
Most site activities take days. A handful of items take months, and they set your critical path:
- VRF/HVAC outdoor units and chillers — 6 to 10 weeks, longer for imported capacity
- Glass partitions and double-glazed acoustic systems — 4 to 8 weeks
- Loose furniture and workstations — 6 to 10 weeks for custom finishes
- AV, video conferencing and access control hardware — 4 to 8 weeks, often the forgotten one
- Imported flooring, veneers and specialist lighting — 6 to 12 weeks
Order these before civil work starts. A project that waits for a “final” furniture decision until the ceiling is up will finish four weeks late regardless of how fast the site team works.
Weeks 8–18: Site execution
On site, the sequence is broadly: demolition and setting out, then civil and blockwork, then first-fix MEP above the ceiling, then ceiling and partitions, then flooring, then second-fix electrical and joinery, then painting and finishes, then furniture, then AV and IT commissioning. Expect roughly 8 to 12 weeks for a warm shell space and 12 to 18 for a bare shell where HVAC, fire systems and electrical infrastructure are being built from zero. If you are still weighing shell types, our comparison of bare shell, warm shell and plug-and-play offices covers what each choice does to both budget and schedule.
Final 2 weeks: Snagging, testing and handover
Testing and commissioning, air balancing, fire system integration, snag list closure, deep cleaning and documentation handover. Teams that treat this as buffer end up moving into a half-finished office. Treat it as a real stage with a real date.
What actually causes delays
In practice, fit-out programmes rarely slip because masons work slowly. They slip because of design changes after tender, late landlord approvals, long-lead items ordered late, split accountability between designer and contractor, and unclear IT and AV requirements arriving in the last month. Four of those five are decision problems, not construction problems.
How to compress the schedule safely
The reliable levers are overlapping stages rather than shortening them. Freeze the brief early and hold it. Release procurement for long-lead items on the back of approved concept drawings instead of waiting for the full BOQ. Submit landlord drawings in the same week the MEP layouts are frozen. Use 3D visualisation to get stakeholder sign-off before detailing, not after — it is far cheaper to change a render than a built ceiling.
The structural lever is the delivery model. Under a single design and build contract, design, procurement and execution sit with one accountable party, which removes the tender gap between design completion and site start and typically saves three to five weeks on a mid-sized office. We break down the trade-offs in design and build vs traditional contracting.
Plan backwards from your lease date
The practical rule: count back at least 20 weeks from your intended occupation date for a warm shell office, and 26 for a bare shell. If you have less runway than that, the honest options are phasing the move, reducing customisation, or accepting a plug-and-play space for the interim — not compressing site work and hoping.
Timeline and budget move together, so build both models at once. Our 2026 office fit-out cost guide gives the per-square-foot side of the equation. If you are scoping a move and want a programme mapped against your lease dates, talk to the AirBrick Infra team — we will work backwards from your handover date and tell you honestly what is achievable.
