BDT 1,800 to 3,500 per sft, depending on design scope
The office interior cost in Dhaka is one of the first questions a business asks after choosing a floor. The answer affects approval, cash flow and the move-in date.
The difficulty is that quotations often describe different work. One may cover selected construction items. Another may include custom furniture. A third may exclude design, air conditioning, chairs and building access charges. Their headline rates are not directly comparable.
This guide explains Studio Archifiction’s office interior fit-out execution cost in Dhaka using delivered-project records. Professional design fees are treated separately unless the quotation includes them. The page separates the execution benchmark, worked budgets, scope, exclusions, renovation conditions, occupancy and programme.

How to read the evidence: Studio Archifiction reviewed its delivered office work and procurement experience in August 2026. The BDT 1,800 to 3,500 band is the practice’s first-party benchmark for turnkey fit-out execution against an agreed BOQ. It is not an independent market index or a project quotation. The market section summarises examples from publicly available price pages reviewed in August 2026. That review was qualitative, not a statistically representative sample.
The short answer on office interior cost in Dhaka
Across Studio Archifiction's delivered office projects, the August 2026 turnkey fit-out execution benchmark is BDT 1,800 to 3,500 per sft.
Here, turnkey means execution, site supervision and handover of the interior work written into the agreed BOQ. Professional design fees, including working drawings and BOQ preparation, are priced separately unless the quotation expressly includes them. Air conditioning, technology, loose furniture, taxes and building charges also remain outside unless listed.
What sets the per-sft office fitout cost in Dhaka
Whether you search for office fitout cost in Dhaka or office interior design cost per square foot in Dhaka, the same question sits underneath: what work is included? The rate depends on the agreed work, not floor area alone.
A floor with extensive storage, partitions, service changes and specialised rooms can sit differently within the band from an open workplace of the same size. The material basis matters too. A low starting rate can produce a higher final bill if necessary work appears later as a variation.
Read these cost groups together:
- custom joinery and storage
- ceiling and lighting
- electrical work
- partitions
- flooring and paint
- furniture, equipment and building requirements that are expressly added
Studio Archifiction prepares working drawings and BOQs and provides site supervision in house for office interior design in Dhaka. This lets the client trace each priced item to an agreed drawing or BOQ line.
Room type also changes scope. A conference room may require audiovisual and information-technology equipment outside the general rate. A CEO or MD room may have a different joinery, storage and privacy brief. Define the room before judging its price.
Calculated budgets by office size
The table shows straight multiplication of the BDT 1,800 to 3,500 execution benchmark before any project-specific small-floor adjustment. These are arithmetic planning ranges, not delivered-project quotations or occupancy promises. Treat it as a simple interior design cost calculator: multiply your measured area by both ends of the band.
| Office area | Lower-end calculation | Upper-end calculation |
|---|---|---|
| 300 sft | BDT 5.4 lakh | BDT 10.5 lakh |
| 500 sft | BDT 9 lakh | BDT 17.5 lakh |
| 1,000 sft | BDT 18 lakh | BDT 35 lakh |
| 2,500 sft | BDT 45 lakh | BDT 87.5 lakh |
| 7,500 sft | BDT 1.35 crore | BDT 2.63 crore |
| 10,000 sft | BDT 1.8 crore | BDT 3.5 crore |
Small-floor warning: These figures are straight-multiplication planning ranges. Because the rate tends to rise below about 500 sft, a 300 sft office may sit toward the upper end. The final figure still requires a defined BOQ.
Small offices have a cost paradox. Below about 500 sft, necessary work is concentrated into less area, so the rate per sft tends to rise. Above about 3,000 sft, repeated work can ease the rate.
This issue is explained further in small office interior design in Dhaka. A test fit is still required before attaching a team size or room capacity to a calculated floor area.
Large corporate and government floors: 5,000 sft and above
Above about 3,000 sft the rate per sft tends to ease. One reception, one set of drawings and one supervision team are carried by far more area, and repeated workstation bays are priced more efficiently than one-off rooms.
For a 7,500 to 10,000 sft floor, Studio Archifiction's planning figure from delivered institutional and corporate projects is roughly BDT 2 to 2.4 crore. Straight multiplication of the band would give BDT 1.35 to 3.5 crore for the same sizes, so the planning figure sits inside the band. It is a planning figure, not a quotation, and it assumes a defined BOQ.
Studio Archifiction has delivered office floors for a2i, UNDP, UNCDF, the Planning Commission and the Prime Minister's Office. The 7,600 sft a2i floor at Daak Bhaban, built by a contractor from Studio Archifiction's tender documents and completed in 2025, is the largest institutional interior in the practice's records. The 10,500 sft Creative Engineers head office across three floors is the largest corporate one.
A large floor changes the work more than the rate. Expect these on a floor of this size:
- Tender-grade documents. On an institutional project the contractor prices the drawings and BOQ, not the intent. A specification that can be read two ways is priced at its cheapest reading.
- Phased handover. Departments move in zone by zone or floor by floor, so sequencing is written into the programme from the start.
- Building protocols. Government and managed buildings control gate passes, working hours and material entry.
- Approval levels. More sign-offs mean the brief is frozen earlier, with sample boards and mock-ups approved before bulk procurement.
Working drawings, BOQ, tender documentation and site supervision are handled in house, which suits a private head office and public-sector procurement alike.

What Studio Archifiction means by turnkey
On this page, turnkey describes end-to-end responsibility for executing, supervising and handing over the interior work listed in the agreed BOQ. It is not an all-inclusive design-and-equipment price.
Studio Archifiction carries out the listed interior work, supervises the site and hands over that listed work. The signed quotation controls the boundary. If an item is absent from the drawings, BOQ and commercial terms, the word turnkey does not add it to the price.
Working drawings, BOQ preparation and site supervision are handled in house. Professional design fees, including the working-drawing and BOQ appointment, are separate from the per-sft execution benchmark unless the quotation expressly includes them. Custom items can be coordinated through the practice's custom furniture workshop in Dhaka in Badda.
The general per-sft rate usually excludes the following unless the quotation expressly includes them:
- VAT and advance income tax, or AIT.
- Professional design fees.
- Audiovisual and information-technology equipment.
- Air conditioning.
- Loose furniture, especially chairs.
- Building gate passes, service-lift bookings, security deposits and after-hours access.
- Price escalation when work starts months after the quotation.
Building obligations deserve their own check. A managed property may require advance item lists, booked delivery windows and deposits before materials can enter. These conditions can affect cost and programme even though they are not interior work.
Why published office prices are hard to compare
During an August 2026 qualitative review of publicly available Dhaka office cost pages, Studio Archifiction observed published examples ranging from roughly BDT 800 to 4,500 per sft. The review also found package totals of BDT 15, 19 and 23 lakh labelled Standard, Premium and Exclusive without a stated floor area.
This was not a statistically representative market study. The examples used different scopes, and package totals without floor area cannot be converted into comparable per-sft costs. They are included only to show why public price claims are difficult to compare. They are not a market average and they are not Studio Archifiction pricing.
One quotation may cover selected construction work. Another may describe a broader fit-out. Design fees, air conditioning, chairs, technology and building charges may sit outside either figure.
The honest comparison is the BOQ, material basis, exclusions and delivery responsibility. The headline rate comes after that. The same principle applies to the wider interior design cost in Bangladesh, for offices and homes alike: the BOQ decides, not the headline.

Why renovation needs a site survey
Office renovation cost in Dhaka needs a surveyed BOQ because the useful life of existing work and the operating conditions of the building cannot be read from area alone.
A shell fit-out begins with fewer inherited decisions. Renovation begins with existing ceilings, electrical routes, partitions, flooring, joinery and services. Some work can remain. Some needs repair. Some must be removed before the new work can proceed.
| Project condition | Correct first step | Reason |
|---|---|---|
| New shell or clearly defined fit-out | Apply the execution benchmark to a written scope | The proposed work can be listed and measured from the brief and drawings. |
| Occupied office | Confirm access and phasing before pricing | Noise, dust, working hours and material movement may need controlled stages. |
| Renovation | Survey retained, repaired and removed work | Existing conditions decide the BOQ. Area alone is not enough. |
On a delivered 2,500 sft office in Mohakhali DOHS, controlling entry windows and batching deliveries mattered as much to the programme as the drawings. That experience is why Studio Archifiction does not publish a separate office renovation cost per square foot without defining what survives and how the site can operate.
See how the practice handles office renovation inside an occupied building.
What changed since 2021
Studio Archifiction's records show a directional movement from a roughly BDT 1,500 blended office-work rate in 2021 to a BDT 1,800 to 3,500 turnkey fit-out execution benchmark in 2026.
| Evidence | 2021 | 2026 |
|---|---|---|
| Office work | Roughly BDT 1,500 per sft blended rate | BDT 1,800 to 3,500 per sft turnkey fit-out execution benchmark |
| One sheet of ply board | Around BDT 2,500 | Close to BDT 3,800 |
The office figures are not mathematically like for like: one is a blended rate and the other is an execution benchmark. The ply-board movement, roughly 50 per cent, is a separate material-cost signal. It is not a construction-price index and does not explain the whole fit-out rate.
It does show why a 2021 quotation cannot simply be carried into 2026. Old totals are context. A current BOQ is the price basis.
What delivered floors actually held
These delivered-project outcomes show what specific Studio Archifiction floors achieved. They are not density standards, legal occupancy limits or promises for another plan.
| Delivered area | Delivered outcome |
|---|---|
| 620 sft | A 10-person startup team with flexible workstations, custom storage and a controlled display area |
| 1,050 sft | A compact creative office |
| 2,500 sft | 32 workstations plus one meeting room |
| 7,600 sft | An institutional floor for a2i with workstations and gallery seating, several small meeting rooms, one large conference room with a seminar stage, reception, lobby and prayer room |
| 10,500 sft across three floors | 80 workstations and three meeting rooms |
The ALTIUS Startup Office provides the 620 sft benchmark. The Pritam Zaman Tower office provides the 1,050 sft benchmark. The Ek-Pay Office provides the 2,500 sft benchmark in Mohakhali DOHS. The a2i floor at Daak Bhaban provides the 7,600 sft institutional benchmark. The Creative Engineers head office provides the 10,500 sft benchmark across three floors.
The pattern is simple. Area does not promise a headcount. Columns, circulation, storage, privacy and room requirements must be resolved on the actual plan.
How long the work takes
For a 2,000 to 4,000 sft office, Studio Archifiction's delivered-project benchmark is 2 to 3 weeks for design and 8 to 10 weeks for execution.
A delivered 10,500 sft head office across three floors ran roughly three to four months from start to handover. These are programme benchmarks, not guarantees. Approval speed, procurement, building access, working hours and floor-by-floor sequencing still affect each project.
Freeze the brief early. Start execution from coordinated drawings.
A fair quotation checklist
Two office quotations are comparable only when they describe the same area, work and delivery responsibility.
- Confirm the measured area and room brief. Both quotations must address the same floor and workplace requirements.
- Align the BOQ. Compare matching lines for construction, joinery, finishes and services.
- Expose exclusions. Add taxes, fees, equipment, air conditioning, chairs and building obligations where applicable.
- Confirm responsibility. Identify who prepares drawings, executes the work, supervises the site and completes handover.
Do not compare the lowest totals first. Compare what each total buys.

Questions clients ask
What is the office interior design cost per square foot in Dhaka?
Studio Archifiction's August 2026 turnkey fit-out execution benchmark is BDT 1,800 to 3,500 per sft, based on delivered projects. It covers execution, site supervision and handover of the interior work listed in the agreed BOQ. Professional design fees and the stated exclusions remain separate unless the quotation expressly includes them.
What does turnkey mean in this cost benchmark?
Turnkey means Studio Archifiction executes, supervises and hands over the interior work written into the agreed BOQ and quotation. It does not mean every operational item is automatically included. Professional design fees, taxes, air conditioning, technology, loose furniture and building charges remain outside unless the quotation expressly includes them.
What budget should I plan for a 1,000 sft office?
Applying the BDT 1,800 to 3,500 per sft band gives a calculated planning total of BDT 18 to 35 lakh for 1,000 sft. It is not a final quotation. The room list, materials, services, access conditions and exclusions still need confirmation through a defined BOQ.
How much does an interior designer cost, separate from execution?
People also search for interior designer cost per square foot or interior design per sqft cost. On this page the per-sft figure is the execution benchmark. Studio Archifiction quotes professional design fees separately: generally BDT 50 to 80 per sft of office area, rising to BDT 100 per sft for a detailed or complex scope, verified September 2026. The proposal states the area being charged and the drawings, design views and BOQ work included; site supervision and execution are priced against their own agreed scope. Ask for the design fee and the execution figure as two lines so you can compare each one fairly.
Is interior design cost in Bangladesh the same outside Dhaka?
Studio Archifiction's benchmark comes from delivered projects in Dhaka. Outside Dhaka, material transport, local labour and building access change the BOQ, so the band should not be copied across as it stands. The method is the same: a measured area, a room brief and a defined BOQ before any rate is applied.
Can a low cost office interior design still work?
Yes, when the scope is reduced deliberately rather than the quality. A low cost office interior design usually means an open plan, fewer partitions, standard finishes and joinery built in phases. The rate per sft does not fall much; the quantity of work does. Decide what can wait, keep the electrical and ceiling work coordinated, and put the money into what people touch every day.
What does a large corporate or government office floor cost in Dhaka?
For a 7,500 to 10,000 sft floor, Studio Archifiction's planning figure from delivered institutional and corporate projects is roughly BDT 2 to 2.4 crore, inside the BDT 1,800 to 3,500 per sft band. A delivered 7,600 sft institutional floor at Daak Bhaban sat inside that band. Tender documents, phasing and building protocols decide the final figure more than the headline rate.
Why can office renovation not be priced from area alone?
Renovation begins with existing work. Ceilings, electrical routes, partitions, flooring and joinery may be retained, repaired or removed. Their condition must be surveyed before the BOQ is prepared. An occupied office can also require controlled entry, restricted working hours and batched deliveries.
How long does an office interior project take in Dhaka?
For a 2,000 to 4,000 sft office, the delivered-project benchmark is 2 to 3 weeks for design and 8 to 10 weeks for execution. A delivered 10,500 sft head office across three floors took roughly three to four months from start to handover. Access and approvals can still change the programme.
How should I compare two office interior quotations?
Confirm that both quotations use the same measured area and room brief. Then align the BOQ, materials, furniture scope and exclusions. Add taxes, equipment, air conditioning and building charges before comparing totals. Finally, check who prepares the drawings, supervises the work and remains responsible through handover.
