To calculate the per square foot rate of consultancy for both architectural and interior design services, we’ll use the given construction costs and consultancy percentages. Here’s the breakdown:
1. Architectural Consultancy Cost
- Standard Construction Cost (excluding interiors): ₹1,800 per sq. ft.
- Architectural Consultancy Fee: 5% of construction cost.
Calculation: ₹90 per square feet (consultancy)
2. Interior Consultancy Cost
- Standard Construction Cost (for interiors): ₹2,400 per sq. ft.
- Interior Consultancy Fee: 12% of construction cost.
Calculation: ₹288 per sq. ft. (consultancy)
3. Total Consultancy Cost per Square Foot
If both architectural and interior consultancy services are required for the same project, the total consultancy cost per square foot would be = ₹90 + ₹288 = ₹378 per sq. ft.
Summary of Consultancy Costs per Square Foot:
| Service | Cost per sq. ft. |
|---|---|
| Architectural Consultancy | ₹90 |
| Interior Consultancy | ₹288 |
| Total Consultancy Cost | ₹378 |
Example Calculation for a 1,000 sq. ft. Project:
- Architectural Consultancy Cost: ₹90 x 1,000 = ₹90,000
- Interior Consultancy Cost: ₹288 x 1,000 = ₹288,000
- Total Consultancy Cost: ₹378 x 1,000 = ₹378,000
