Two more ways a project takes shape.
Modular Kitchens
Kitchens planned around how you actually cook and host, then built with cabinetry and hardware chosen to survive that use for years.
- Layout planning
- Cabinetry
- Hardware
- Finishes
Renovation
Reworking a space you already live in — a different problem from fitting out an empty flat, and one that has to be sequenced around your life.
- Full-home
- Room-level
- Sequencing
Start from the problem, not the service name.
Most people arrive knowing what is wrong with their space and not which service fixes it. These are the situations we are asked about most, and where each one leads. If yours is not here, it is a conversation rather than a category.
We have just been handed an empty flat.
A full residential fit-out: layout, joinery, finishes and services from a bare shell. This is the most straightforward case to plan, because nothing has to be worked around and every decision is still open.
Residential interiorsWe are living here and something has to change.
Renovation. A different discipline from fitting out an empty flat — the work has to be sequenced around the household, sealed off, and often paused, and that sequencing decides both cost and how bearable it is.
RenovationOnly the kitchen is the problem.
A modular kitchen on its own is a legitimate standalone project, and usually the single largest concentrated cost in a home. Worth doing properly even if the rest of the house waits.
Modular kitchensWe are moving into or reworking a workplace.
Commercial. The design overlaps with residential; the constraints do not — a lease, a landlord, building services, multiple approvers and a date that costs money if it slips.
Commercial interiorsWe have ideas but no plan, and we are not ready to build.
Design consultation. Concept, material direction and a buildable plan, without committing to execution in the same breath. It is also the right starting point when two people want different things and the brief has to be settled first.
Design consultationWe do not want to coordinate contractors ourselves.
Turnkey execution. One studio holds design and build together, so nothing is handed off midway and re-interpreted — which is where most of the cost and most of the delay in an interiors project actually comes from.
Turnkey executionWe are trying to compare quotations we already have.
Nothing to buy here yet — the cost article sets out what each line in a quotation means, why two honest quotes for the same flat differ, and an eight-question worksheet for making them comparable.
Comparing quotationsFrom first conversation
to final handover.
Four stages, one team throughout. You deal with the same people from the first sketch to the day the space is handed over — nothing is passed to a separate contractor midway.

We start with how you actually live
Concept development, material guidance and clear design direction — the conversation that turns rough ideas into a refined, buildable vision for the space.

Finishes, furnishings, and decorative detail
Curated finishes, styling selections, and elevated decorative details are developed together — including material curation and any bespoke furniture — so the palette is settled before building begins.

We manage every detail on site
Turnkey execution from first sketch onward. We coordinate the work so the project feels effortless from start to finish, rather than becoming something you have to manage.

Final decoration, styling, and handover
The last layer — bespoke furnishings, beautiful decoration, and the styling that carries the promise every project is held to: it should feel like home the moment you step in.
Not sure which stage you're at?
Most projects start with a conversation, not a drawing. Full walkthroughs, drawings and material boards are shared during consultation.
What you decide, and when.
The four stages above are what we do. This is what is asked of you — worth knowing before you start, because the cost of a decision depends almost entirely on which stage it is made in. Nearly every interiors project that runs over does so because a decision that belonged in one column was actually made in the next one.
Before consultation
- Who the decision-makers are, and whether they agree
- A rough sense of budget — even a wide band helps more than none
- What is not working about the current space, in specifics
Cost of changing it here: Costs nothing to change. Changing it later is what makes projects drift.
During design
- The layout — where walls, doors and services go
- Material and finish direction, against boards rather than descriptions
- What is in scope and what waits for a later phase
Cost of changing it here: Cheap to change on a drawing. This is the stage worth taking slowly.
Before execution
- Sign-off on the layout and the specification
- Whether you live or operate in the space during the work
- Anything you are supplying yourself, and when it arrives
Cost of changing it here: The last point at which changes are inexpensive.
During execution
- Decisions on anything the site uncovers that the drawings could not
- Approval of variations as they arise, not at the end
Cost of changing it here: Changes here mean undoing work already done. Kept to a minimum by the three stages above.

A Legacy of Craft
Three and a half decades of design leadership, built on trust, taste, and timeless execution.
Luxury, Defined
Premium residential and commercial interiors with an elegant, function-first approach.
Home-Like Service
Warmth, care, and a personal commitment to every client — homely atmosphere, every time.
Three things that shape every project.
A legacy of craft
Three and a half decades of design leadership, built on trust, taste and timeless execution. Experience of that length mostly shows up in the unglamorous places — knowing which materials fail early, which layouts people stop using after a month, and what actually goes wrong on site.
Design and execution together
The studio designs and executes. That matters most when something unexpected appears mid-project, because the person who has to solve it is the person who designed it — there is no handover to a separate contractor where responsibility quietly changes hands.
Home-like service
Warmth, care and a personal commitment to every project. Interiors work is disruptive by nature and clients live with the disruption — how a studio behaves during that period is as much a part of the work as the drawings.

+91 79806 40714Do you handle the building work, or only the design?
Both. Alongside design consultation we take on turnkey execution — from the first sketch to the final styling, we manage every detail so the project feels effortless from start to finish rather than becoming something you have to coordinate yourself.
Do you work on offices and shops, or only homes?
Both. Residential work covers warm, modern homes shaped around how you actually live. Commercial work covers brand-first offices and retail environments designed to impress clients and keep teams inspired and productive.
What happens in the first consultation?
It is a conversation rather than a presentation. We talk through the space, how you use it and what you want it to become, then move into concept development, material guidance and clear design direction. Full walkthroughs, drawings and material boards are shared during consultation.
Do you supply furniture and materials, or do we source them?
Material curation and bespoke furniture are part of what we do, so you are not left to source and match everything yourself. Finishes and furniture are chosen as part of the design rather than bolted on at the end.
Who will actually be working on my project?
Avaya Udyog is led by Mr. Biswanath Adhikari, who brings over 35 years of industry experience. Because the same studio handles design and execution, you deal with one team throughout — nothing is handed to a separate contractor partway through.
How much does an interior project cost?
There is no single rate, because cost follows scope — the size of the space, how much is being rebuilt rather than refreshed, and the materials chosen. We would rather understand the project first than quote a number that turns out to be wrong. Costing is discussed openly during consultation, once there is something real to cost.
How long does each stage take?
We have not published stage durations, and we would rather say that plainly than give you a number that is not grounded in your specific project. Scope, site condition and how quickly material decisions are settled all move the schedule substantially. Ask during consultation, where it can be answered against a real space.
Can I make changes once the design is agreed?
Changes are normal, and the stage they arrive at decides what they cost. A layout change during design is inexpensive; the same change during execution means undoing work already done. This is why the design stage is worth taking slowly.
Where are you based?
We are an interior design studio in Kolkata, West Bengal. The quickest way to find out whether we can take on a particular space is to call or send an enquiry — we will tell you straight away.
