The Founder's Guide to Corporate Interior Budgets
Unlike residential design, commercial interiors are heavily governed by structural compliance, fire safety rules, and employee ergonomics. Under-budgeting a commercial fit-out can delay your operational launch by months.
1. Workstations and Density
The core metric of office design is the Square Foot per Employee ratio.
- High Density (IT/Call Centers): typically ~60-80 sqft per employee. Uses linear bench workstations with simple fabric dividers. Highly cost-effective.
- Medium/Low Density (Corporate HQs): typically 100-150+ sqft per employee. Features spacious L-shaped desks, massive boardrooms, and expansive breakout zones (cafeterias, game rooms). Costs scale rapidly due to premium furniture and wasted floor space.
2. The Invisible Costs: MEP & Fire Safety
Most casual estimates completely ignore MEP (Mechanical, Electrical, and Plumbing).
If you are leasing a Bare Shell property, you must install massive HVAC ducting across the ceiling and drop electrical lines to every single desk. More importantly, commercial buildings mandate rigorous Fire Safety systems. You will need to install smoke detectors, fire sprinklers at specifically measured distances, and a PA (Public Address) system. MEP usually consumes 25-35% of a commercial budget.
3. Glass Partitions: Aesthetic vs Acoustic
Modern offices rely heavily on glass partitions to segment Managers' Cabins and Conference rooms while maintaining an open feel.
- Standard Glass (10mm-12mm): Cost-effective but offers poor sound insulation. Suitable for standard manager cabins.
- Double-Glazed Acoustic Glass: Used in premium corporate boardrooms to ensure absolute privacy. These are extremely expensive and require specialized aluminum frames (like Dormakaba or ozone).
4. IT Networking (Passive)
Do not forget the cost of cabling. While companies buy their own laptops, the interior fit-out must include the "Passive IT" infrastructure. This involves laying thousands of meters of Cat6 or Fiber cabling under the floor or above the ceiling, terminating at desk faceplates, and routing back to a heavily cooled, secured Server Rack room.
Commercial Contractors: Pitch with Precsion
Corporate clients demand itemized transparency. Use Interify CRM to generate enterprise-grade BOQs spanning hundreds of line items—from HVAC tonnage to Cat6 nodes—in a beautifully formatted PDF.

Commercial office interior costs vary significantly across Indian business hubs, influenced by local labor rates, material availability, and regulatory compliance requirements.
| Business Hub | Standard Rate/Sqft | Premium Rate/Sqft | Key Factors |
|---|---|---|---|
| Mumbai (BKC, Andheri) | ₹2,200-3,000 | ₹4,500-6,500 | Highest labor costs, premium material access |
| Delhi NCR (Gurgaon, Noida) | ₹1,800-2,500 | ₹3,500-5,000 | Competitive market, good vendor ecosystem |
| Bangalore (Whitefield, ORR) | ₹1,500-2,200 | ₹3,000-4,200 | Tech hub, modern design preferences |
| Hyderabad (HITEC City) | ₹1,200-1,800 | ₹2,500-3,500 | Growing IT sector, cost-effective |
| Chennai (IT Corridor) | ₹1,100-1,600 | ₹2,200-3,200 | Established market, competitive pricing |
| Pune (Hinjewadi, Magarpatta) | ₹1,300-1,900 | ₹2,600-3,800 | Quality-focused, good craftsmanship |
6. MEP Systems: The Hidden Budget Killer
Mechanical, Electrical, and Plumbing (MEP) systems often consume 30-40% of commercial fit-out budgets but are frequently underestimated in initial planning.
HVAC System Breakdown
Cassette AC Units
- • Cost: ₹45,000-65,000 per unit
- • Coverage: 400-600 sqft each
- • Installation: ₹8,000-12,000 per unit
- • Best for: Small to medium offices
Central VRV/VRF Systems
- • Cost: ₹2,50,000-4,50,000 per system
- • Coverage: 3,000-8,000 sqft
- • Ducting: ₹80-120 per sqft
- • Best for: Large corporate offices
Fire Safety Compliance Costs
Mandatory Fire Safety Systems
- • Smoke Detection System: ₹25-40 per sqft (sensors every 80 sqft)
- • Sprinkler System: ₹45-70 per sqft (wet/dry pipe systems)
- • Fire Alarm & PA System: ₹15-25 per sqft
- • Emergency Lighting: ₹20-35 per sqft
- • Fire Extinguishers & Hose Reels: ₹8-15 per sqft
- • NOC & Compliance Fees: ₹50,000-2,00,000 (varies by city)
7. Workstation Design and Ergonomics
Modern office productivity depends heavily on ergonomic workstation design. The choice between different workstation types significantly impacts both budget and employee satisfaction.
| Workstation Type | Cost per Seat | Space Required | Best Use Case |
|---|---|---|---|
| Linear Bench (4-seater) | ₹18,000-25,000 | 60-70 sqft/person | Call centers, high-density IT |
| L-Shaped Workstation | ₹28,000-40,000 | 80-100 sqft/person | Software development, design teams |
| Executive Workstation | ₹45,000-70,000 | 120-150 sqft/person | Senior managers, team leads |
| Hot Desking Stations | ₹15,000-22,000 | 50-65 sqft/person | Flexible/hybrid work models |
8. Technology Infrastructure and Passive IT
Modern offices require extensive technology infrastructure that goes beyond just providing desks and chairs. The passive IT infrastructure forms the backbone of any functional workspace.
Passive IT Infrastructure Components
Structured Cabling (₹180-250/sqft)
- • Cat6/Cat6A cables to each desk
- • Fiber optic backbone cabling
