How to Choose the Right Interior Design Firm in Dhaka: 12 Questions to Ask Before Signing

Why Choosing the Right Interior Design Firm in Dhaka Matters for Your Commercial or Residential Project

When you’re about to invest BDT 5 lakh to BDT 20+ lakh (or significantly more for commercial, hospitality, or multi-floor projects), selecting an interior design firm is not a decision to rush. The wrong choice leads to budget overruns, project delays, substandard execution, and stress that compounds weekly. The right choice delivers a space that functions well, looks professional, and increases property or business value.

In Dhaka’s fast-growing design market, hundreds of firms claim expertise. Some are legitimate professionals with proven portfolios and transparent processes. Others are freelancers with minimal accountability, firms that disappear mid-project, or contractors masquerading as designers who prioritize speed and margin over quality or code compliance.

This guide provides 12 critical questions to ask any interior design firm in Dhaka before signing a contract, explains what transparent, professional answers look like, identifies red flags that should concern you, and shows what clients should expect when working with a firm like House De Arch.

Understanding What You’re Actually Hiring: Designer vs. Contractor vs. Full-Service Firm

Before asking questions, understand the difference between service models in Dhaka’s interior design market:

• Freelance Designer: Produces drawings and mood boards, but you manage contractors, procurement, and execution. Cost: typically BDT 300-800/sq.ft design fee only.
• Design-Only Firm: Delivers complete design and drawings but hands off execution to third parties. You coordinate implementation.
• Full-Service Design-Build Firm: Handles design, procurement, contractor coordination, and handover. Single point of accountability. Common for commercial projects, offices, restaurants, and high-value residential work.
• Contractor Claiming Design: Primarily executes construction; design is secondary, often template-based or copied. Risk: poor spatial planning, code non-compliance, aesthetic compromise.

Most serious commercial clients and residential clients with budgets above BDT 10 lakh choose full-service firms for accountability and integrated project management. Understand what you’re hiring before you start comparing quotes.

The 12 Questions to Ask Before Signing Any Interior Design Contract in Dhaka

These questions separate professional firms from amateurs. Listen carefully to how firms answer—evasiveness, vague promises, or refusal to document commitments in writing are immediate red flags.

1. What Is Your Firm’s Legal Registration Status and Professional Credentials?

Why it matters: Legal entities offer recourse; unregistered individuals or informal operations offer none. If a sole proprietor or unregistered “studio” disappears or fails to deliver, you have limited legal options.

What to ask:

• Is your firm registered with RJSC (Registrar of Joint Stock Companies) or as a legal business entity?
• Do your lead designers or architects hold degrees from recognized institutions (BUET, Ahsanullah, foreign accredited programs)?
• Are any team members registered with the Institute of Architects Bangladesh (IAB) or similar professional bodies?

Red flag: Refusal to share registration documents, vague answers like “we’re working on it,” or claiming credentials without proof.

HDA’s answer: House De Arch is a registered firm. Our team includes BUET-trained architects and designers with IAB affiliations and documented portfolios spanning 50+ residential and commercial projects across Dhaka, Chattogram, and beyond. We provide registration details and team credentials transparently upon request.

2. Can I See a Portfolio of Completed Projects Similar to Mine, Including Client References?

Why it matters: Past work predicts future capability. A firm that has never designed a restaurant should not claim expertise in restaurant interior design. A portfolio with only renderings but no built photos suggests limited execution experience.

What to ask:

• Can I see 3-5 completed projects in my category (office, retail, residential, hospitality)?
• Are these photos of actual built work or just renderings?
• Can you provide contact details for 2-3 past clients I can speak with?

Red flag: Only computer renderings, no built projects. Refusal to share client references. Portfolio filled with copied images from Pinterest or international sites (reverse image search if you’re unsure).

HDA’s answer: We maintain a documented portfolio of completed residential, office, retail, and hospitality projects. Clients receive project-specific case studies and, with prior client consent, references for direct conversation. Our work is built, occupied, and functioning—not hypothetical.

3. What Does Your Design and Execution Process Look Like, With Defined Timelines?

Why it matters: Professional firms follow structured processes: concept, design development, drawings, approvals, procurement, execution, handover. Firms without defined processes wing it, causing delays and scope creep.

What to ask:

• What are the phases of your process from contract signing to handover?
• How long does each phase typically take for a project of my size?
• What are the client approval checkpoints?
• How do you handle changes or revisions mid-project?

Red flag: Vague timelines (“we’ll finish when it’s done”), no defined approval stages, promises of unrealistic speed (a 2,000 sq.ft office interior in 30 days is not credible if quality matters).

HDA’s answer: Our process includes: (1) Briefing & site survey, (2) Concept design & client approval, (3) Detailed design, drawings & BOQ, (4) Procurement & contractor engagement, (5) Execution & site supervision, (6) Quality checks & handover. For a typical 1,500 sq.ft apartment interior, expect 8-14 weeks depending on scope and material lead times. Timelines are documented in contracts with milestone-based payments.

4. Who Will Actually Be Designing and Managing My Project Day-to-Day?

Why it matters: Some firms showcase senior designers in pitches but assign junior staff or interns to actual projects. You deserve to know who is accountable.

What to ask:

• Who is the lead designer assigned to my project, and what is their experience?
• Will I have a dedicated project manager or single point of contact?
• How often will senior leadership review my project?

Red flag: Evasive answers, promises that “the founder will handle everything” (unrealistic for firms with multiple concurrent projects), or no clear accountability structure.

HDA’s answer: Every project is assigned a lead designer and a project manager. Clients meet their team during contract signing. Senior architects review design milestones and site progress weekly. You will have direct access to your project manager via phone and WhatsApp throughout execution, with formal review meetings bi-weekly or as needed.

5. What Is Included in Your Fee, and What Are Potential Additional Costs?

Why it matters: Transparent firms separate design fees, execution costs, and potential variables upfront. Opaque firms lowball quotes and introduce hidden costs later.

What to ask:

• Is your fee design-only, or does it include execution/project management?
• What exactly is included: drawings, 3D renderings, material procurement, site supervision, contractor coordination?
• What potential costs are not included (e.g., structural modifications, RAJUK approvals for commercial fit-outs, custom imported materials)?
• How do you handle cost escalations if material prices rise mid-project?

Red flag: Quotes given verbally without written breakdown. Firms that refuse to provide itemized estimates. Vague answers like “everything is included” without documentation.

HDA’s answer: Our proposals separate: (1) Design fee (typically BDT 250-600/sq.ft depending on complexity), (2) Execution cost based on detailed Bill of Quantities (BOQ) with material/labor/contractor margins transparent, (3) Exclusions stated clearly (e.g., RAJUK fees, owner-supplied items, structural engineering if needed). Clients receive written cost estimates before contract signing. Material cost escalations beyond 10% are discussed and approved before proceeding.

6. How Do You Handle Material Procurement and Quality Control?

Why it matters: Material quality determines longevity and safety. Firms that source cheap, uncertified materials or take undisclosed kickbacks compromise your project.

What to ask:

• Where do you source materials (local suppliers, importers, specific brands)?
• Can I approve materials and finishes before purchase?
• Do you allow client-supplied materials if I prefer specific brands?
• How do you verify material quality and authenticity (e.g., for fire-rated panels, engineered wood, electrical fittings)?

Red flag: Refusal to disclose suppliers. Pressure to accept materials without client review. No quality certifications or material testing for safety-critical items (fire safety, load-bearing elements, electrical).

HDA’s answer: We source from established Dhaka suppliers (Otobi, Hatil, Partex, RFL, Asian Paints, and specialized importers for commercial-grade materials). Clients approve all material selections via sample boards. We accommodate client-supplied materials with advance notice. For commercial projects, we ensure materials meet BNBC fire safety and structural codes, particularly for restaurants, hotels, and offices.

7. What Happens If the Project Runs Over Budget or Timeline?

Why it matters: Even well-planned projects can face delays (supplier issues, client-requested changes, site conditions). Professional firms have contingency plans and change-order processes.

What to ask:

• What is your track record for delivering on time and on budget?
• How do you handle delays caused by suppliers, contractors, or unforeseen site issues?
• What is the process for client-initiated changes mid-project (additional cost, timeline impact)?
• Do you offer any guarantees or penalties for delays caused by your team?

Red flag: No mention of contingency planning. Blaming all delays on “market conditions” or clients. No formal change-order process.

HDA’s answer: We build 10-15% time buffers into schedules for supplier delays and unforeseen issues. Client-initiated changes are documented via written change orders with cost and timeline impacts stated before approval. Delays caused by our execution errors (not client changes or force majeure) are absorbed without additional client cost. Our contracts specify milestone deadlines and consequences for non-performance.

8. Do You Carry Professional Liability Insurance or Provide Warranties?

Why it matters: Errors happen. Insured firms or those offering warranties demonstrate confidence in their work and protect clients from financial loss due to design or execution failures.

What to ask:

• Do you carry professional liability or errors & omissions insurance?
• What warranty do you provide on executed work (structural, finishes, installations)?
• How do you handle defects discovered post-handover?

Red flag: No insurance, no warranty, or verbal-only promises. Firms that vanish after final payment.

HDA’s answer: We provide a 12-month warranty on all executed work covering structural integrity, finish defects, and installation failures (excluding normal wear or client misuse). Post-handover, clients have direct access to our service team for any issues. While professional liability insurance is still emerging in Bangladesh’s design sector, we maintain documented processes and financial stability to stand behind our commitments contractually.

9. How Do You Ensure Compliance With RAJUK, BNBC, and Fire Safety Regulations?

Why it matters: Commercial fit-outs, restaurants, offices, and multi-story residential projects must comply with RAJUK building codes and BNBC fire safety standards. Non-compliance risks fines, closure orders, or safety hazards.

What to ask:

• Are you familiar with RAJUK approval requirements for commercial interior modifications?
• Do your designs comply with BNBC fire safety codes (exit widths, fire-rated materials, emergency lighting)?
• Will you handle or coordinate any required RAJUK submissions or fire safety certifications?

Red flag: Ignorance of RAJUK or BNBC requirements. Promises to “handle it later” or suggestions to skip approvals. For commercial projects, this is a serious liability.

HDA’s answer: All our commercial, office, and hospitality projects are designed to BNBC fire safety standards from day one. For projects requiring RAJUK approvals (structural changes, commercial fit-outs in regulated buildings), we coordinate submissions or work with clients’ architects of record. Compliance is non-negotiable for life safety and legal operation.

10. What Is Your Payment Structure and Contract Terms?

Why it matters: Payment terms reflect risk distribution. Fair terms tie payments to milestones. Exploitative terms demand large upfront payments with no accountability.

What to ask:

• What is your payment schedule (e.g., 30% advance, 40% at mid-execution, 30% at handover)?
• Are payments tied to deliverables or milestones?
• What are the termination clauses if either party needs to exit the contract?
• Is there a retention amount held until defects are resolved?

Red flag: Demand for 70-80% upfront before any work begins. No written contract. Refusal to tie payments to milestones. No termination or dispute resolution clauses.

HDA’s answer: Our standard terms: 20-30% advance upon contract signing, 40-50% in milestone-based installments tied to design approvals and execution stages, 20-30% upon final handover with retention clauses for warranty period. All terms are documented in written contracts with clear deliverables, timelines, and dispute resolution mechanisms. We use milestone-based payments to protect both parties.

11. How Do You Communicate Progress and Handle Client Feedback?

Why it matters: Poor communication is the top complaint about design firms. Professional firms provide regular updates, welcome feedback, and document decisions.

What to ask:

• How often will I receive progress updates (weekly reports, site photos, meetings)?
• What tools do you use for client communication (email, WhatsApp, project management software)?
• How quickly do you respond to client questions or concerns?
• How do you document and implement client feedback?

Red flag: Vague promises of “we’ll keep you updated.” Unresponsiveness during the sales process (a preview of project experience). No documentation of client decisions.

HDA’s answer: Clients receive bi-weekly progress reports with site photos and milestone updates. Your project manager is reachable via phone and WhatsApp during business hours, with response times under 24 hours for non-emergencies. Major decisions (material approvals, layout changes) are documented in writing or email for mutual clarity and accountability. Transparency and frequent communication are part of our project management standard.

12. Can You Provide a Written Contract Before I Commit?

Why it matters: Verbal agreements are unenforceable. Written contracts protect both parties by clearly stating scope, cost, timeline, responsibilities, and remedies.

What to ask:

• Will you provide a detailed written contract before I make any payment?
• Does the contract include: scope of work, fees, payment terms, timeline, deliverables, warranties, termination clauses, and dispute resolution?
• Can I have my lawyer review the contract before signing?

Red flag: Refusal to provide a written contract. Pressure to pay before contract review. Contracts with missing scope, timeline, or cost details. Contracts heavily one-sided in the firm’s favor.

HDA’s answer: Every client receives a comprehensive written contract covering all project aspects before any payment is made. We encourage clients to review with legal or financial advisors if desired. Our contracts are designed for mutual clarity and fairness, not to trap clients in unfavorable terms. Transparency begins with documentation.

Red Flags That Should Make You Walk Away From an Interior Design Firm in Dhaka

Beyond the questions above, watch for these red flags during your evaluation:

• No physical office or showroom: Firms operating entirely remotely or from residential addresses may lack infrastructure or permanence.
• Pressure tactics: “Sign today for a discount,” “we’re very busy, slots filling up,” or similar urgency without substance suggests desperation, not demand.
• Plagiarized portfolio: If images look too good or too international, reverse image search them. Stolen portfolios are surprisingly common.
• Unwillingness to visit your site before quoting: Accurate quotes require site surveys. Firms quoting over the phone without seeing your space are guessing.
• No online presence or reviews: In 2025, legitimate firms have websites, social media, and client reviews. Total anonymity is suspicious.
• Refusal to answer tough questions: If a firm evades questions about credentials, costs, timelines, or references, assume they’re hiding problems.

Trust your instincts. If something feels off during initial conversations, it will likely worsen during a multi-month, multi-lakh project.

FAQ

How much should I expect to pay an interior design firm in Dhaka for a 1,500 sq.ft apartment?

For a full-service interior design project (design + execution), expect BDT 6-15 lakh for a 1,500 sq.ft apartment, depending on material quality, custom work, and finishes. Design-only fees typically range from BDT 250-600/sq.ft. Always request itemized estimates before committing.

What is the difference between a design-only firm and a design-build firm in Dhaka?

Design-only firms create drawings, material specs, and concepts but do not handle execution—you coordinate contractors and procurement. Design-build firms (like House De Arch) manage the entire process from concept through handover, providing single-point accountability for design, materials, contractors, and quality.

Do I need RAJUK approval for commercial interior fit-outs in Dhaka?

Yes, if your commercial interior involves structural modifications, changes to load-bearing elements, or occupancy changes in RAJUK-regulated buildings. Professional firms ensure designs comply with RAJUK building codes and BNBC fire safety standards and coordinate necessary approvals.

How long does a typical office interior design project take in Dhaka?

A 2,000-3,000 sq.ft office interior typically takes 8-12 weeks from contract signing to handover, including design approvals, procurement, and execution. Timelines vary based on scope, custom millwork, imported materials, and client decision speed. Firms promising completion in 3-4 weeks for quality work are unrealistic.

What should be included in an interior design contract in Bangladesh?

A comprehensive contract should include: detailed scope of work, itemized cost breakdown, payment schedule tied to milestones, project timeline with key dates, team assignments, material specifications, warranty terms, change-order process, termination clauses, and dispute resolution mechanisms. Never proceed without a written contract.

How can I verify if an interior design firm’s portfolio is authentic?

Request to see built project photos (not just renderings), ask for project addresses you can visit (with client permission), request client references you can contact, and reverse image search portfolio photos to ensure they aren’t copied from international sites. Authentic firms welcome verification.
