Architect fees in India are structured three ways: a percentage of project cost, a lump-sum fee tied to deliverables, or a rate per square foot. Understanding what each model’s number does and does not commit to is the knowledge you need before you can meaningfully compare any two quotations.
The COA Scale of Professional Charges: what it is and isn’t
A fee guidance document published by the Council of Architecture under the Architects Act, 1972. It sets out recommended percentages by project category — residential, institutional, commercial — and by project cost range, published at coa.gov.in.
- Guidance, not tariff: the scale is a professional guidance document rather than a legally binding rate. Individual architects may charge above or below it based on scope, complexity and market conditions.
- Roughly 2–5% for residential: higher percentages apply to smaller projects, where the architect’s effort is proportionally greater relative to construction value, and lower percentages to very large ones.
- Use it as a sanity check: homeowners can reference the scale to judge whether a fee proposal sits within the normal professional range.
The critical gap: what the scale does not specify is which services are included within that percentage. Which is exactly why a fee can be entirely COA-scale-compliant and still cover a very different scope from another that looks identical. The percentage tells you the price. Only the written scope tells you what you are buying.
The Three Fee Models compared
Rated across the four measures that matter to a homeowner:
Percentage of project cost
2–5% of total construction cost for residential
Lump sum, deliverable-based
Fixed amount for a defined scope, paid in stages
Per square foot
A rate multiplied by built-up area
Why lump sum is marked as recommended: it is the only one of the three that scores well on all four measures at once. The homeowner pays only for something received and approved; the architect knows exactly what has been committed to and what has not. Percentage and per-sqft become equally transparent the moment an equally specific deliverables list accompanies them — the model itself is not the problem, the missing list is.
Percentage of project cost
A defined percentage of total construction cost. On a ₹1 crore construction, a 3% fee is ₹3 lakhs. This is the model referenced in the COA scale.
- Where it works well: complex or large projects where full scope genuinely cannot be defined upfront, and institutional or commercial work where construction value is known early and scope changes are tracked through a variation order process.
- The problem case: an architect quoting ‘architectural services at 3%’ without a scope list is quoting a percentage for an undefined scope. The percentage commits you to a fee; the absence of a list commits the architect to nothing specific. The homeowner discovers mid-project that working drawings are extra, MEP co-ordination is extra, and site visits are extra.
- How to protect yourself: always require a deliverables list alongside the percentage, identical to what you would require for a lump-sum engagement. A percentage quote with a complete list is exactly as transparent as lump-sum pricing.
Lump Sum, deliverable-based
A fixed total fee for a specifically listed scope — concept design, 2D floor plans, 3D renders, approval drawings, working drawings, MEP layout, BOQ co-ordination and site support visits. Each stage payment releases when the corresponding deliverable is complete and approved.
The structure protects both parties. The homeowner pays only for something received and approved. The architect is clear about what has been committed and what falls outside it. Variation orders — changes made after a stage completes — are assessed and priced before execution, rather than accumulating as a surprise at project end.
Typical Stage payment structure
Five stages. The right-hand column is the part worth reading closely — it is what gives the schedule its leverage:
Design work stalls; no obligation to produce developed design
Working drawing stage does not begin; approval drawings not produced
Approval filing cannot proceed; development charges cannot be computed
Contractor cannot build; BOQ-based construction contract cannot be signed
Site visits do not occur; design intent goes unmonitored during construction
Each stage payment buys a specific document, and withholding it stops a specific thing from happening. That is the whole mechanism: the schedule is only protective because each trigger is verifiable. A payment tied to ‘completion’ or to a calendar date gives you nothing to withhold against.
Every Payment Tied to Something You Can Hold in Your Hand
A lump-sum fee structure with a complete scope list and a five-stage payment schedule — so you pay only when a deliverable has been produced and approved.
Per Square Foot and why it misleads
Built-up area multiplied by a rate. A 2,000 sq.ft home at ₹75/sq.ft produces a ₹1.5 lakh fee. Widely used across India for quickly communicating an approximate figure, and the least transparent of the three because the rate almost never arrives with a scope list.
- The core problem: a per-sqft rate for approval drawings only and a per-sqft rate for complete service look identical. The first produces a set of drawings the planning authority will accept — but not drawings a contractor can build from. The second produces a complete construction document set.
- When it is acceptable: as shorthand in a first-meeting ballpark discussion. It is not acceptable as the sole basis for a contract without a full scope definition alongside it.
- How to protect yourself: ask which drawings the rate includes. If the list matches what you need to build — concept, floor plans, 3D, approval, working drawings, MEP, BOQ, site visits — then the per-sqft rate is simply another way of expressing a deliverable-based fee. If working drawings and site visits are missing from the list, it is an approval-only fee.
What a Full-Service Fee should include
Nine items. If a proposal omits any of them, that omission should be explicit rather than discovered later:

| Include | Service |
|---|---|
| Concept design — two to three floor plan options for selection before detailed design begins | |
| Developed 2D floor plans — all levels, fully dimensioned, with room names, door and window schedule, furniture layout | |
| 3D elevation renders — all facades with exterior material palette, allowing approval before structural commitment | |
| Approval drawings — TNOBPAS submission format, area statement, development charge computation, filed by a COA-registered architect with Class 3 DSC | |
| Structural co-ordination — the architect reviews the engineer’s column and beam grid against the floor plan and resolves clashes before working drawings issue | |
| MEP layout drawings — electrical conduit routing, water supply, drainage and HVAC routing within the working drawing set | |
| Working drawings — joinery, staircase section, bathroom and kitchen layouts, door and window schedules: the construction-ready set | |
| BOQ co-ordination — materials specified by brand, grade and quantity, approved before the construction contract is signed | |
| Construction site support — milestone visits across a minimum of six stages, site report within 48 hours, drawing clarification and variation assessment |
Typically excluded and quoted separately: the structural engineer’s fee, landscape design, furniture and movable design, 3D interior visualisation (sometimes included, sometimes extra), and the geotechnical or soil test fee. Ask for this exclusion list explicitly — it is as informative as the inclusion list.

Factors That Affect architect fees
- Project size: larger projects typically attract a lower percentage, since the architect’s proportional effort does not scale linearly with project value. Smaller projects attract a higher percentage for the same reason.
- Project complexity: a luxury villa with a feature facade, post-tensioned slab and smart home integration takes more design hours than a standard 3BHK G+1 of equal area. Complexity justifies a higher absolute fee.
- Scope of services: approval drawings alone cost less than approval plus working drawings plus MEP plus BOQ plus site support. The scope must be defined before the fee means anything.
- Seniority and track record: established practices with verifiable completed projects command higher fees. The premium is partly design quality and partly professional risk management.
- Location and constraints: premium localities, or plots with complex planning constraints such as marshland buffer zones, DP road setbacks or CRZ, command higher fees for the additional regulatory and design work.
Verify, Prepare, Then Read the Fee
The registration check comes first, the meeting preparation second, and the fee proposal third — each guide covers one stage of hiring an architect properly.
How to Compare fee quotations
Swipe or scroll to see the full table →
| Check | Before comparing any two numbers |
|---|---|
| Confirm every quotation covers the same scope — approval drawings only, or full service from concept through site support | |
| Add the estimated cost of missing services to any quotation excluding working drawings, MEP or site visits | |
| Ask each architect what is explicitly excluded — structural engineer’s fee, landscape, furniture, 3D interiors | |
| Confirm the stage payment structure is deliverable-triggered, not time-based or arbitrary | |
| Confirm the revision rounds included at each stage, and what happens once they are exceeded | |
| Confirm the COA-registered architect’s name and number appear on the quotation itself | |
| Cross-check the total against COA scale guidance for your project type and cost range | |
| Refuse to compare on rate or percentage alone where the two scope lists are different |
The COA scale tells you whether the fee is in the professional range. Only the scope list tells you whether it is for a complete or a partial service.

Frequently Asked Questions
How much do architects charge in India?
Fees typically range from 2–5% of project construction cost for residential work, per COA Scale of Professional Charges guidance. That translates to roughly ₹75,000–2,50,000 for a standard G+1 Chennai home depending on scope. The exact figure depends on complexity, scope of services and the practice’s seniority. The COA Scale is guidance, not a legally binding tariff.
What is the COA Scale of Professional Charges?
A fee guidance document published by the Council of Architecture under the Architects Act, 1972, providing recommended fee percentages by project category and value. It is not legally mandatory but is widely referenced as the professional benchmark. Homeowners can use it to evaluate whether a fee proposal sits within the normal professional range.
Is per-square-foot architect pricing reliable in India?
It is commonly used for quick fee communication but unreliable as the sole basis for an engagement. The rate almost never specifies what is included — in many cases it covers only approval drawings, not working drawings, MEP layout or site visits. Always ask for a specific scope list alongside any per-sqft rate before treating it as a commitment.
What should be included in an architect fee in India?
A full-service fee should include concept design with multiple options, developed 2D floor plans, 3D elevation renders, approval drawings, structural co-ordination, MEP layout, working drawings covering joinery, staircase, bathroom and kitchen, BOQ co-ordination, and milestone construction site visits. The structural engineer’s fee, landscape and furniture design are typically quoted separately.
Which architect fee model is best for homeowners in India?
Lump-sum, deliverable-based pricing is the most transparent, because every payment ties to a specific verifiable deliverable. It protects the homeowner by ensuring payment only for work received and approved, and protects the architect by defining scope clearly from the start. Percentage and per-sqft fees are equally acceptable when accompanied by an equally specific deliverables list.
A Number You Can Actually Compare
A lump-sum, deliverable-based fee structure with the complete scope list, the exclusion list and the stage-payment schedule written out — as standard, before you commit to anything.
The number is meaningless without the scope
Architect fees in India stop being confusing once you accept that the number — percentage, lump sum or per-sqft rate — means nothing without the scope list that says what it covers. A fee from a practice covering concept through working drawings and site visits, and a fee from a practice covering approval drawings alone, look identical until you read the scope. The COA scale gives you a benchmark for whether the fee is in the professional range; the scope list tells you whether it buys a complete or a partial service. Buildiyo’s architectural services in Chennai use a lump-sum, deliverable-based structure with a complete scope list and stage-payment schedule as standard.
