Architect Fees in Delhi — Engagement Models and What You're Buying

Percentage of project cost vs flat fee vs stage-wise; what each model actually covers; and how to avoid scope drift.
There is no single compulsory private-market architect fee for every Delhi project. Practices agree a fee against scope, complexity, responsibility, duration and the cost base, while the Council of Architecture publishes Conditions of Engagement and a Scale of Charges that remains an important professional reference. A percentage without its scope is not comparable: two proposals quoting the same number can include different consultants, drawings, site involvement and completion support. This guide shows how to read the model behind the headline.
The four common engagement models
1. Percentage of project cost (full scope)
A percentage model is useful when design and construction run as one long appointment and the final scope will mature over time. The agreement must define “cost of works assigned”: does it include civil structure, fixed interiors, external works, contractor-supplied equipment, taxes, escalation or client-purchased items? It must also say when an estimate becomes the certified or actual cost and how the fee is reconciled. Do not assume that sanction, tender, weekly visits or completion documentation are included merely because the fee is a percentage.
2. Flat fee
A lump sum can work well for a defined renovation, fit-out, feasibility or drawing package. Predictability comes from boundaries, not from the words “fixed fee”. State the measured area, rooms or buildings, deliverables, included options and revisions, programme, site visits and consultant interfaces. Then state how added area, redesign after approval, delayed construction or extra visits are authorised and priced.
3. Stage-wise / lump-sum per phase
Architect is paid at the end of each phase: concept, scheme design, working drawings, sanction submission, tender, construction administration. Either at fixed amounts or as percentages of an estimated total. Most flexible model for clients who want to step out after concept or sanction. Watch out for: making sure the construction-administration phase is properly priced — it’s the longest phase and the one most often under-quoted.
4. Hourly retainer (consulting only)
Less common for residential, more common for owners who already have a contractor in place and want an architect for a bounded review. The proposal should name the people and rates, minimum billing unit, meeting and travel treatment, what counts as an output, invoicing evidence and a not-to-exceed cap. It suits a specific brief such as reviewing a kitchen layout; it is a poor substitute for a full drawing package when the contractor needs coordinated construction information.
The Council of Architecture scale: the useful benchmark
The CoA page headed Scale of Chargesis marked last updated 21 October 2015. It describes minimum fees or additional charges against stated service scopes; it is not evidence that every 2026 Delhi proposal must use one market percentage. Read it together with the Conditions of Engagement, current professional obligations and the project’s signed appointment.
| CoA category | Posted scale | Scope caution |
|---|---|---|
| Comprehensive services—individual house | 7.5% of cost of works assigned | Excludes separate interior, landscape, graphics/signage unless appointed |
| Single-block housing/site up to 0.5 hectare | 5% of cost of works assigned | Do not confuse a housing development category with one private house |
| Projects other than housing | 5% of cost of works assigned | Comprehensive architectural scope as described by CoA |
| Conservation, retrofitting, additions and alterations | 7.5% of cost of works assigned | Investigation and specialist consultant scope still need definition |
| Interior architecture | 7.5% of cost of works assigned | Separate service category, not automatically inside architecture |
| Landscape architecture | 7.5% of cost of works assigned | Separate service category |
| Contractor-bill verification | 1% in addition to the stated fees | Based on measurements and contract information described by CoA |
| Documentation and communication | 10% of professional fees | Confirm how the appointment treats digital/physical deliverables and expenses |
This distinction explains why an architect may quote comprehensive architecture, interiors and construction management as separate lines. Combining them can be convenient, but the client should still see the service boundary. Our architecture service lists its deliverables, while construction managementcovers procurement, records, bills and site controls under a separately defined appointment.

Worked examples for all four engagement models
These examples demonstrate arithmetic and contract structure only. They are not Archaus quotations, recommended market rates or a promise that the example scope suits your project.
Percentage example
An individual house assigns ₹1.50 crore of civil and fixed-finish work to the comprehensive architecture scope. At the CoA scale’s 7.5% individual-house reference, the professional fee is ₹11.25 lakh before applicable taxes, reimbursables and separately appointed services. If fixed interiors are not in “works assigned”, their cost does not silently enter the base; if interior architecture is later appointed, its scope and fee are documented.
Flat-fee example
A measured one-floor renovation has a hypothetical ₹18 lakh design fee: ₹3 lakh for survey/brief/concept, ₹4 lakh for design development, ₹6 lakh for working drawings and tender, and ₹5 lakh for the stated construction-review period. The total remains ₹18 lakh if the defined area and programme remain unchanged. A second floor, redesign after sign-off or visits beyond the stated period follow the additional-service mechanism in the appointment.
Stage-wise example
A client authorises a hypothetical ₹12 lakh appointment one phase at a time: 15% or ₹1.80 lakh for brief and concept, 20% or ₹2.40 lakh for developed design, 30% or ₹3.60 lakh for coordinated construction/tender drawings, 30% or ₹3.60 lakh during construction administration, and 5% or ₹60,000 at the defined close-out. If the client stops after developed design, later phase fees are not earned—but they also do not receive later-phase drawings.
Hourly-retainer example
A bounded peer review uses an illustrative ₹5,000 hourly rate with a 40-hour cap. After 26 documented hours, the invoice is ₹1.30 lakh before taxes. Work stops or seeks written authority before exceeding ₹2 lakh. The letter says whether site travel, meeting notes and drawing mark-ups consume the cap and identifies the architect who performs the review. A capped hourly model without time records is not transparent.
You can test percentage, flat and stage-wise scenarios in the architect fee calculator. Its result is a planning comparison; the appointment still governs.
What the fee should include
- All design phases: concept, scheme, design development, working drawings.
- Sanction drawing preparation (AAA fee usually separate; ask).
- Structural coordination (structural engineer fee usually separate).
- Tender documentation: BOQ, technical specifications, drawing index.
- Contractor selection: shortlist, comparative analysis, recommendation.
- Site visits during construction: typically 1–2 per week or as project demands.
- Material approvals and shop-drawing reviews.
- Final inspections and snag list resolution.
What is typically outside the fee
- Liaison and approvals fees (MCD, structural NOC, fire NOC). Real costs passed through.
- Specialist consultants: structural engineer, MEP, landscape, lighting designer if separate.
- Site survey, soil test, contour survey.
- Drawings printing and physical models beyond an agreed allowance.
- 3D rendering beyond an agreed number of views.
- Project Management Consultancy (PMC) — if separately offered, typically 2–3% of project cost on top.
How to avoid scope drift
Most fee disputes between owners and architects come from mid-project additions that one side considered “part of the job” and the other considered new scope. The fix is upfront clarity:
- Define the deliverables per phase. List sheet count, drawing scale, and what each drawing must show.
- Define the number of revisions per phase. Three rounds at scheme design is typical; beyond that is hourly.
- Define site-visit frequency. Once a week vs once a fortnight is a real difference.
- Define what triggers a change order. A 5%+ shift in built-up area; a change in spec level; an extension of programme beyond a stated end date.
Also define ownership and permitted use of instruments of service, client-supplied information, consultant responsibility, suspension/termination, dispute resolution, taxes and reimbursables. For a local new build, the sequence on our Pitampura architect page helps map those deliverables to real phases. The Courtyard Houseis a useful case study of why concept, structure, detailed interfaces and site decisions cannot be compressed into one “drawing” milestone.
The contract that protects both sides is the contract that names the deliverables, not the contract that names the fee. Owners often spend an hour negotiating the percentage and ten minutes glancing at the scope. It should be the other way around.
Payment phasing
Typical phasing for a percentage-of-cost engagement:
- 10% retainer on contract signing.
- 15% on concept design approval.
- 20% on scheme design and sanction submission.
- 25% on working drawings issued for construction.
- 25% during construction, in monthly billings.
- 5% on completion certificate.
That split is illustrative, not a CoA-prescribed payment schedule. Match invoices to deliverables and the actual duration of construction administration. Define what “concept approved”, “issued for construction” and “close-out” mean, and do not leave a year of site work supported by a token final percentage.
What our fee looks like
We choose the commercial model after the brief, property, stage, consultant structure and expected site involvement are understood. Every proposal carries a scope and exclusion schedule before drawing starts. Ask for a project-specific fee letter when you are ready to discuss those inputs.
