Architect fees in India: percentage, per sq ft or lump sum

There are three common ways. A percentage of the construction cost is the most usual for a house. A per sq ft fee is common for drawings only, with fewer site visits. A lump sum suits a small or very clear job, like an extension or a single floor.

The Council of Architecture (CoA) publishes Conditions of Engagement and a Scale of Charges. For an individual house it lists a minimum of 7.5% of the cost of works. For additions, alterations and retrofitting it is also 7.5%. Its own notes say fees on works up to ₹15 lakh may be negotiated.

In practice the fee is agreed between you and the architect. Small practices and tier-2 cities often quote lower. Well-known studios and complex designs quote higher.

The CoA breaks full service into seven stages. Ask your architect which of these are in the fee.

1. Concept design and a rough cost estimate.
2. Preliminary design and a preliminary estimate, for your approval.
3. Drawings for sanction by the local authority.
4. Working drawings, specifications and a schedule of quantities for tender.
5. Inviting and comparing contractors' quotes.
6. Construction: detail drawings, samples, shop drawings and periodic site visits.
7. Completion: as-built drawings and help with the completion or occupancy certificate.

Periodic site visits are not daily supervision. The CoA terms say day-to-day supervision is by a site supervisor or construction manager whom you appoint and pay. Budget for one.

The CoA schedule ties payments to stages, not dates. Each figure below is the share of the total fee paid by the end of that stage.

The fee itself is worked out on the real construction cost at the end, not counting land. Early stages are billed on the estimate, so expect an adjustment at handover. Our architect's fee calculator splits the payments on this schedule; if your agreement sets a different one, follow that.

Say your house will cost ₹60 lakh to build, excluding land. At the CoA's 7.5%, the fee is ₹4,50,000. GST at 18% adds ₹81,000, so you pay ₹5,31,000.

• Across the market range of 4–12%, the same house would cost ₹2,40,000 to ₹7,20,000 in fees, before GST.
• If documentation charges of 10% are added, that is another ₹45,000 on a ₹4,50,000 fee.
• By the time drawings go for sanction you would have paid about 30% of the fee, or ₹1,35,000 before GST.
• A structural engineer is often about 0.5–1.5% of construction cost, or roughly ₹30,000–90,000 here. This is general practice, not a published rate: treat it as an estimate.

Our house calculator folds the architect and structural engineer together at about 5% for a basic house up to 11% for a luxury one.

• Don't cut the construction stage. Site visits catch mistakes that cost far more than the fee.
• Freeze the brief early. Revisions after approval are where fees and delays grow.
• If budget is tight, agree a design-only fee with a fixed number of site visits, and hire a good site supervisor.
• Compare quotes on the same scope: number of site visits, 3D views, interiors, landscape and approvals.

• Hiring without a written agreement listing stages, deliverables, site visits and payment steps.
• Assuming the fee includes structural design, approvals liaison or interiors.
• Paying by date rather than by finished stage.
• Not checking the architect is registered with the Council of Architecture. You can search the register on its website.

An architect leads the design and the sanction drawings. A structural engineer designs the frame and foundations, often brought in by the architect. A contractor builds it. For anything beyond a simple house, ask the architect to name the structural engineer before you sign.
