Architect, Interior Designer, or Execution Contractor: Who Do You Actually Need?
You have a flat, a budget, and three quotes from three firms that describe themselves in almost identical language. One is a licensed architecture practice, one is a design studio, one is a fit-out contractor. The work they are offering to do is not the same work.
AlcorOne Solutions is an execution-first interior contracting firm delivering turnkey residential and commercial fit-outs across South India. It is headquartered in Chennai, with offices in Hyderabad, Visakhapatnam and Rajamahendravaram. All work is manufactured in-house and assembled on site — no subcontracting, no surprise substitutions mid-project.
The architect
In India, "architect" is a protected title. Only a person registered with the Council of Architecture under the Architects Act, 1972 may use it, and that registration is what allows drawings to be signed and submitted for statutory approval. That is the distinction that matters: an architect can take responsibility for structure, statutory compliance, and anything that alters the building itself.
For an apartment interior, you need an architect when the work touches the building rather than the fit-out — moving or opening a wall, altering a wet area's plumbing stack, enclosing a balcony, or anything the housing society or municipal body will want signed drawings for. For a fit-out inside an unchanged shell, you usually do not.
The interior designer
"Interior designer" is not a protected title in India. There is no statutory register, no licence, and no legal barrier to using the term. That is not an accusation — the field contains excellent practitioners, and many hold serious formal qualifications. It does mean the title alone tells you nothing, and you have to look at the portfolio and the drawings instead.
What a designer sells is a design: spatial planning, material and finish selection, lighting design, joinery detailing, and the drawing set that describes all of it. A good designer's output is buildable — dimensioned elevations, sections through joinery, a finish schedule, and electrical and plumbing point layouts that a contractor can price and build from without inventing anything.
The execution contractor
A fit-out contractor builds. The output is a finished flat, not a drawing set. What you are buying is procurement, factory or site fabrication, on-site sequencing across carpentry, electrical, plumbing, painting and installation, quality control on incoming material, and a warranty on the result.
This is the role AlcorOne occupies, and it is worth being blunt about the consequence: a contractor takes delivery risk. If the board delaminates or the alignment fails, that is a warranty claim against the firm that built it. A design-only engagement does not carry that exposure, which is precisely why the two roles price so differently.
How the three actually combine
| Your project | Who you need | Why |
|---|---|---|
| Apartment fit-out, shell unchanged | Execution contractor, with in-house or bought-in design | No statutory drawings required. One accountable party for both design and delivery. |
| Fit-out with walls moved or wet areas relocated | Architect for the alteration, then a contractor to build | Structural and statutory work needs a signed drawing. The fit-out does not. |
| You have a designer you want to keep | Designer for drawings, contractor to build to them | The common and workable split — provided the drawing set is complete enough to price. |
| Villa or independent house, new build | Architect leading, contractor under them | Structure, services and interiors are one continuous problem here, not separable. |
Can you buy drawings only?
Yes, and it is a legitimate thing to want. Buyers ask for it in two situations: they intend to run the build themselves with individual trades, or they want an independent design they can competitively tender.
Both work, with one condition. A drawing set bought without an execution partner has to be complete, because there is nobody to fill the gaps on site. In practice that means dimensioned elevations for every joinery item, sections through anything non-standard, a finish schedule keyed to the drawings, electrical and plumbing point layouts with heights, and a hardware schedule naming brand and model. If a design package stops at 3D renders and a mood board, it is not a buildable set — it is a proposal, and whoever builds it will be making decisions you did not approve.
The honest warning on the tendering plan: an incomplete drawing set makes quotes less comparable, not more, because every contractor prices the gaps differently. See BOQ vs quotation for how that plays out.
Questions that separate the three quickly
- "Are you registered with the Council of Architecture?" A yes means an architect. A no is not a problem unless your work needs signed drawings.
- "Who holds the warranty on the built work?" A designer will say the contractor. A contractor will say themselves. If nobody says themselves, stop.
- "Show me a dimensioned elevation from a past project, not a render." This separates firms that draw from firms that visualise.
- "Do you execute, or do you appoint and supervise?" Both are valid models — a project management consultant supervising trades is a real service — but the accountability differs sharply. See PMC vs contractor.
- "What happens if a material in the drawing is unavailable?" The answer tells you who is empowered to make substitutions, and whether you get asked first.
The honest limit of the distinction
Plenty of firms genuinely do two of these roles, and a few do all three competently. The taxonomy is not a way of ruling firms out — it is a way of knowing what you have bought. The failure mode is not hiring a designer when you needed an architect; it is reaching handover having assumed someone was accountable for something nobody agreed to.
One party should own the built result in writing. Everything else — who drew it, who supervised, who procured — is a structuring decision you are free to make however suits you.

Frequently asked questions.
Do I need an architect for an apartment interior in Bengaluru?
Usually not, if the shell stays as the builder handed it over. You need one when the work alters the building — removing or opening a wall, relocating a wet area's plumbing, enclosing a balcony — because those need drawings someone is licensed to sign, and many housing societies ask for them before allowing work. A fit-out inside an unchanged shell does not require a registered architect.
Is an interior designer more expensive than a contractor?
They are not comparable, because they are selling different things. A designer typically charges a fee for a drawing set, as a percentage or a lump sum. A contractor prices the built work, with design either included or bought in. A design-only fee looks smaller because it excludes materials, labour, procurement and warranty — the majority of what a fit-out costs.
Can an execution contractor build to my designer's drawings?
Yes, and it is a normal arrangement. What determines whether it goes well is the completeness of the drawing set — dimensioned elevations, sections, finish schedule, point layouts and a hardware schedule. Where a set is incomplete, the contractor either asks or assumes, and the second one is what causes disputes.
How are AlcorOne projects paid for?
Projects require an upfront deposit of 20% of the total contract value before work begins, adjusted against the final invoice. The remaining payment is released in milestones tied to project progress — material procurement, civil and carpentry completion, finishing and handover — and the exact milestone schedule is agreed in writing for each project, since it varies with project size, scope and site conditions. Anything not listed in the signed BOQ is out of scope until it is agreed in writing as a variation, costed and confirmed before execution. Published rates are exclusive of GST.
What warranty does AlcorOne give on its interior work?
Three tiers, stated separately because they cover different things and expire at different times. Ten years on the plywood carcass from the date of handover, against delamination, borer attack and manufacturing defect in the board — conditional on the grade specified in the signed BOQ being the grade supplied and installed. One year on installation and workmanship: alignment, levelling, fixing, edge-banding and similar. Hardware, fittings and appliances carry the manufacturer's own term, and AlcorOne registers that documentation in the client's name at handover and facilitates the claim. Not covered under any tier: water ingress originating from base-building or plumbing defects outside AlcorOne's scope; damage from misuse, unauthorised modification, or third-party work carried out after handover; and normal wear to finishes.
The three roles are not competitors. They are stages, and a project goes wrong when one of them is quietly missing rather than when the wrong one is hired.
AlcorOne is an execution contractor. We build to a designer's or architect's drawings where you have them, bring in a partner architect where the work needs signed drawings, and hold the warranty on what we build either way.
Already have drawings? We build to them.
