Most people sign with a design firm after seeing a beautiful portfolio and a handshake. Then the surprises start.

Before you commit to any architecture or interior firm in Dhaka, these 7 questions can save you lakhs in hidden costs, delays, and legal headaches:

1️⃣ Can you show completed projects I can visit?
Why it matters: Renders lie. Real spaces don't. If a firm only shows 3D visuals, you have no proof they can execute.
Red flag: "Our clients value privacy" for every project.
Transparency: A firm confident in its work will arrange at least one site visit.

2️⃣ Who owns the design files if the project ends early?
Why it matters: If you part ways mid-project, can you take the drawings to another firm or are you starting from zero?
Red flag: Vague answers or "that's in the fine print."
Transparency: Clear IP clauses in the contract, upfront.

3️⃣ What's included in your fee vs. billed separately?
Why it matters: "Design fee" might exclude RAJUK submissions, site visits, or revision rounds — costs that add up fast.
Red flag: "We'll discuss that later" or no itemized breakdown.
Transparency: A line-item proposal showing design, documentation, approvals, supervision separately.

4️⃣ How do you handle material procurement?
Why it matters: Some firms buy materials directly (transparent pricing), others add 15–25% markup without disclosure.
Red flag: Reluctance to share supplier invoices or "we handle everything."
Transparency: Clear policy — whether you're paying cost-plus, markup, or purchasing independently.

5️⃣ What's your average project delay rate and causes?
Why it matters: Every firm faces delays. Honest ones track and explain them (RAJUK approvals, supplier issues, scope changes).
Red flag: "We always deliver on time" (unrealistic) or blaming clients for every delay.
Transparency: Historical data and a process for managing risks.

6️⃣ Do you carry professional liability insurance?
Why it matters: If a design error causes structural issues or RAJUK rejection, are you protected?
Red flag: "Never needed it."
Transparency: Valid policy details, willingly shared.

7️⃣ Can I speak with 3 recent clients?
Why it matters: References reveal how a firm handles problems, communication, and budget.
Red flag: Only offering one cherry-picked client or none.
Transparency: Multiple references from the past 12 months, across project types.

At House De Arch, we built our practice on these conversations — not avoiding them. Every client gets clear contracts, completed project visits, itemized proposals, and reference lists before signing.

If your current shortlist can't answer these seven clearly, you're not being difficult. You're being smart.

Save this checklist for your next design firm meeting. And if you want a firm that welcomes these questions, not dodges them — let's talk.

Your 1,400 sq ft Gulshan apartment feels like 900 sq ft – and it's not in your head.

Most Dhaka developers design apartments like they're filling a Tetris grid: maximum units per floor, minimum thought to how people actually live. The result? Layouts that look spacious on paper but feel suffocating the day you move in.

Here are 5 layout mistakes we fix in nearly every apartment project – without touching a single load-bearing wall:

1️⃣ THE CORRIDOR TAX
Developers carve out 80–120 sq ft hallways connecting bedrooms because it's the laziest solution. We remove non-structural partitions and create open circulation zones – suddenly your living area breathes.
Cost: ৳45,000–৳85,000

2️⃣ THE KITCHEN CAGE
A closed-off kitchen makes both the kitchen AND living room feel smaller. Our move: a breakfast counter opening with a sliding glass partition. You get the open feel, control cooking smells when needed, and gain usable counter space.
Cost: ৳75,000–৳1,40,000

3️⃣ COLUMNS IN ALL THE WRONG PLACES
BNBC structural requirements mean columns – but developers drop them wherever the engineer says, ignoring furniture flow. We wrap them in custom built-ins: TV units, display shelves, wardrobe extensions. The column becomes the feature.
Cost: ৳55,000–৳1,20,000 per column

4️⃣ ONE-LAYOUT BEDROOMS
Most bedrooms are sized for exactly one bed position. We use modular furniture + strategic space planning to give you 2–3 layout options, so the room works whether it's a master suite, guest room, or future nursery.
Cost: ৳35,000–৳70,000 (planning + modular coordination)

5️⃣ THE FORGOTTEN BALCONY
Developers treat balconies as code-compliance afterthoughts. We turn them into weatherproof extensions – reading nooks, mini offices, morning coffee zones with proper lighting and seating.
Cost: ৳60,000–৳1,50,000

None of these solutions require RAJUK approvals. None involve structural changes. All of them make your apartment feel like the space you paid for.

If your Dhaka apartment feels like it's working against you, the layout's probably the reason – and it's fixable.

DM us your floor plan. We'll tell you what's stealing your space (and what we'd do about it).

Your interior designer just said '3 more weeks' for the fourth time this month. Here's why that keeps happening in Bangladesh—and how we fixed it.

Bangladesh interior projects routinely run 6-8 weeks longer than Dubai or Singapore timelines. Not because designers are slow—because the ecosystem is fundamentally different.

The real bottlenecks:
• Specialty materials stuck in Chittagong customs for 2-3 weeks (Italian tiles, German fixtures, premium wallcoverings)
• Local suppliers work on order-basis with 3-4 week lead times—zero buffer stock
• Skilled finishing trades (false ceiling installers, premium woodworkers) are booked months out
• Load-shedding halts workshop production 4-6 hours daily
• Monsoon (June-Sept) adds 15-20% timeline padding to any project

Most firms quote 8 weeks, deliver in 14. Clients blame the designer. The designer blames Bangladesh.

House De Arch runs a different system:

✅ Strategic pre-ordering: We place material orders during your approval phase—not after signing. Customs delays happen while you're reviewing mood boards, not after construction starts.

✅ Vetted supplier network: 8 years building relationships with suppliers who hold buffer stock for our projects. We don't order—we reserve.

✅ In-house project managers: One PM coordinating 6-8 trades simultaneously, not waiting for Trade A to finish before Trade B starts.

✅ Weather-adaptive scheduling: Outdoor/wet work front-loaded before monsoon, interior finishing scheduled for June-August when we can't pour concrete anyway.

✅ Modular design approach: Furniture fabrication, millwork, and soft furnishings happen in parallel workstreams—not sequential.

Result: Our average commercial fit-out (1,800-2,500 sft restaurant/office) completes in 6-8 weeks. Industry average for the same scope? 10-14 weeks.

The timeline difference isn't about working faster. It's about working inside Bangladesh's actual conditions—not pretending we're in Singapore.

If you've been burned by delayed projects before, you're not asking the wrong questions. You were working with a firm that hadn't solved the Bangladesh problem.

Currently managing delayed projects with another firm? DM us for a second-opinion timeline audit—we'll show you exactly where the bottlenecks are and whether they're fixable.

That BDT 3.5 lakh 'repair bill' your contractor just handed you? It was completely avoidable at the design stage.

We see Dhaka businesses make the same costly commercial interior mistakes over and over—errors that seem minor during fit-out but cost BDT 2-5 lakh (or more) to fix months later when operations are disrupted.

Here are the 6 most expensive ones:

❌ Mistake 1: Ignoring load-bearing walls in layout plans
You can't just 'open up' that wall for your café seating area. Now you need a structural engineer, RAJUK amendments, and beam reinforcement. Cost to fix: BDT 3-5 lakh.
HDA approach: We verify structural drawings with your building's engineer before any layout is finalized.

❌ Mistake 2: Choosing cheap imported furniture that breaks within 6 months
That 'premium' chair from an unknown supplier? It collapsed. Now you're replacing 40 units mid-season.
HDA approach: We source from verified Dhaka suppliers (Otobi, Hatil, Regal) or specify commercial-grade imports with warranties—furniture that survives actual Dhaka use.

❌ Mistake 3: Undersizing HVAC for Dhaka's heat and humidity
Your 1,200 sq ft restaurant has 2-ton ACs. It's 32°C inside at lunch hour. Customers complain. You're now adding split units and upgrading electrical.
HDA approach: We calculate cooling loads for Dhaka climate + occupancy + kitchen heat, then specify systems (Gree, Carrier, Daikin) that actually work here.

❌ Mistake 4: Skipping waterproofing in washrooms and pantries
Seepage appears on the floor below after 8 months. Now you're ripping out tiles, waterproofing, re-tiling—and dealing with an angry landlord. Cost: BDT 2-4 lakh + lost business days.
HDA approach: Mandatory waterproofing (Basf, SIKA) in all wet areas, with contractor supervision during application.

❌ Mistake 5: Poor electrical planning requiring disruptive rewiring
You need more outlets for POS systems. Conduits weren't planned. Now cables run exposed or you're breaking walls.
HDA approach: We map electrical loads by zone (coffee station, POS, kitchen, signage) and design conduit routes for future flexibility.

❌ Mistake 6: No maintenance-access planning for ceiling fixtures and AC units
Your false ceiling looks great—until the AC drain blocks or an LED panel fails. Now you're damaging ceiling tiles every service call.
HDA approach: We design access panels at all service points and specify modular ceiling systems for easy maintenance.

Every one of these mistakes is avoidable with proper design and specification—and every one costs significantly more to fix than to prevent.

If you're planning a commercial...

Your ৳180,000 laminate floor bubbled after one monsoon – here's what survives Dhaka's 80%+ humidity instead.

Dhaka's climate destroys the wrong materials fast. We see it constantly: warped wardrobes, peeling walls, rusted hinges within 18 months. After 12+ years designing spaces across Bangladesh, here's what actually lasts:

1️⃣ FLOORING
✅ Vitrified porcelain tiles (₹55–95/sqft): zero moisture absorption, 15+ year lifespan
❌ Laminate (₹45–70/sqft): swells at edges during monsoon, needs replacement in 3–5 years

2️⃣ WALL FINISHES
✅ Breathable emulsion paints + anti-fungal primer (₹18–32/sqft): prevents mold buildup common in Dhaka homes
❌ Non-breathable plastic paints: trap moisture, peel within 2 monsoons

3️⃣ FURNITURE MATERIALS
✅ Engineered wood with marine-grade sealing (₹850–1,400/sqft for built-ins): stable in humidity
❌ Unsealed solid wood: warps, cracks, and expands – we've seen ৳75,000 wardrobes unusable in 18 months

4️⃣ UPHOLSTERY FABRICS
✅ Polyester-cotton blends (60/40 ratio): dry fast, resist mildew
❌ Pure cotton/linen: absorb moisture, develop odor and mold in Dhaka's 6-month wet season

5️⃣ HARDWARE & FIXTURES
✅ Marine-grade stainless steel (304 grade, ₹280–450/piece): rust-free even in high-humidity bathrooms
❌ Chrome-plated mild steel: visible rust spots within 8–12 months

We specify every material in our projects against Dhaka's average 78% humidity (rising to 85%+ June–September). The upfront cost difference? Usually 12–18%. The maintenance savings over 10 years? 60–70%.

For RAJUK-regulated commercial projects, moisture-resistant material selection isn't optional – it's the difference between a space that works and one that requires costly remediation.

Most new business owners in Dhaka think BDT 5 lakh will transform their 1,200 sq ft shop or office. Here's what that budget actually gets you – and what BDT 8-12 lakh can realistically deliver.

We're breaking down real commercial interior costs because too many clients sign leases before understanding fit-out reality.

For a 1,200 sq ft office or retail space in Dhaka, BDT 8-12 lakh (roughly BDT 667-1,000/sq ft) typically covers:

✅ Flooring: Vinyl planks or homogeneous tiles (not marble, not engineered wood)
✅ Lighting: LED panel mix with accent spots in key zones – not full designer fixtures throughout
✅ Paint: Premium emulsion + one feature wall (wood slat or textured panel)
✅ Furniture: Mid-range modular desks/counters, laminate finish (not veneer)
✅ Basic electrical/AC prep work included
✅ Timeline: 35-45 days from handover

❌ What's NOT included: RAJUK approvals if structural, high-end imported materials, custom millwork beyond one feature, full FF&E package

This isn't the Instagram-perfect fitout. It's the smart, durable, business-ready space that actually works within SME and startup budgets in Bangladesh.

Want a space that looks premium but respects your P&L? That's where material knowledge and local sourcing experience make the difference.

We've done this exact scope for pharmacies in Dhanmondi, co-working zones in Banani, and retail outlets in Gulshan – clients who needed clarity before committing capital.

That awkward corner where nothing fits, the hallway that feels like a maze, the sofa blocking your only window – your 1,400 sq ft Gulshan apartment shouldn't feel this cramped.

Most Dhaka apartments feel smaller than they are because of 7 fixable space planning mistakes we see in nearly every residential brief:

1️⃣ Furniture blocking circulation paths
Your 3-seater sofa pushed against the balcony door isn't just inconvenient – it kills airflow and natural light. Solution: Float furniture 18–24 inches from walls; create clear 36-inch walkways.

2️⃣ No zone definition in open layouts
Living-dining-kitchen bleeding into one visual mess? Use area rugs, partial-height screens, or ceiling treatments to define zones without walls.

3️⃣ Ignoring natural light paths
Placing your dining table or workspace away from windows wastes Bangladesh's best free resource. Map sunlight movement first, then arrange furniture.

4️⃣ Oversized furniture in modest rooms
That imported sectional might look stunning in the showroom, but in a 12×14 ft Dhanmondi living room, it devours space. Scale matters more than style.

5️⃣ No focal points
Eyes wandering aimlessly = space feeling chaotic. Every room needs one anchor – a feature wall, window view, or statement piece – that organizes everything else.

6️⃣ Dead corner space
Corners aren't dumping grounds for fake plants. Custom corner shelving, reading nooks, or angled furniture turns wasted square footage into purpose.

7️⃣ Closed floor plans from the '90s
Removing one non-load-bearing wall (with RAJUK structural clearance) can transform two dark 10×10 rooms into one breathable 10×20 space.

Space planning isn't about buying less furniture – it's about intentional placement, proportion, and light. We've added 200+ usable square feet to Dhaka apartments without changing a single wall, just by fixing these mistakes in our layout drawings.

Confused whether your Dhaka commercial project needs an architect or an interior designer? Here's exactly when you need which (and when you need both).

ARCHITECT needed when:
→ New construction or building extensions
→ Structural changes (knocking down walls, adding floors)
→ RAJUK plan submissions and building approvals
→ BNBC compliance (fire safety, load calculations, exit requirements)
→ Façade design and building envelope work

INTERIOR DESIGNER needed when:
→ Office fit-outs without structural changes
→ Restaurant/retail space planning and layout optimization
→ Material selection, finishes, lighting, and FF&E
→ Renovations that don't touch load-bearing elements
→ Branding and spatial identity work

BOTH needed when:
→ Converting a shell space into a functional commercial environment
→ Renovations involving MEP upgrades + aesthetic overhaul
→ Hotel, showroom, or mixed-use projects with regulatory + design complexity
→ You want seamless coordination (one team, one vision, zero finger-pointing)

At House De Arch, we handle architecture AND interior design under one roof. That means your Gulshan office fit-out or Banani restaurant doesn't bounce between multiple consultants—our integrated team manages RAJUK approvals, structural coordination, and interior ex*****on as one smooth process.

Most Dhaka commercial projects benefit from both disciplines working together from day one. Saves time, prevents costly rework, and delivers spaces that actually work—not just on paper.

কয়েকদিন ধরে একটা বিষয় খুব বেশি চোখে পড়ছে।

বাংলাদেশে অনেক restaurant, retail shop আর commercial space-এর owner এখন interior design-এ আগের চেয়ে অনেক বেশি টাকা খরচ করছেন।

কিন্তু একটা প্রশ্ন আমার মাথায় আসছে—
এত টাকা খরচ করার পরও কতগুলো interior আসলে business-এর জন্য কাজ করছে?

কারণ একটা জায়গা দেখতে সুন্দর হলেই সেটা ভালো commercial design হয়ে যায় না।
একটা restaurant সুন্দর হতে পারে।
Instagram-এ খুব ভালো ছবি আসতে পারে।
দামি furniture থাকতে পারে।
Imported light থাকতে পারে।

কিন্তু customer যদি ঢুকে ৩০ সেকেন্ডের মধ্যে বুঝতেই না পারে কোথায় বসবে, কীভাবে order করবে, কোন জায়গাটা তার জন্য comfortable তাহলে সেই interior-এর সৌন্দর্যের business value কতটুকু?

এখানেই আসল বিষয়টা।
Commercial interior decoration আর commercial interior design এক জিনিস না।
Decoration-এর কাজ হলো জায়গাটাকে সুন্দর করা।
Design-এর কাজ হলো জায়গাটাকে কাজ করানো।

আমি যখন কোনো restaurant, retail outlet বা commercial space দেখি, প্রথম প্রশ্ন করি না -
“দেয়ালে কী colour দিলে সুন্দর লাগবে?”

আমি বরং দেখি-
Customer কোথা দিয়ে ঢুকবে?
প্রথম ৫ সেকেন্ডে সে কী দেখবে?
কোথায় দাঁড়াবে?
কোথায় বসবে?
কীভাবে movement করবে?
কোন জায়গাটা সবচেয়ে বেশি চোখে পড়বে?
কোন জায়গায় মানুষ ছবি তুলবে?
কোন জায়গায় বসলে বেশি সময় থাকবে?
আর সবচেয়ে গুরুত্বপূর্ণ -
এই interior কি business-এর sales বাড়াতে সাহায্য করবে?

ধরেন একটা fashion outlet।
দোকানের interior-এর পেছনে ২০ লাখ টাকা খরচ হলো।
সবকিছু premium।
কিন্তু customer ঢোকার পর product discovery কঠিন।
Walking path ঠিক নেই।
Best-selling products-এর visibility কম।
Trial room-এর location inconvenient।
Checkout area awkward।
তাহলে সমস্যা interior-এর budget-এ না।
সমস্যা design strategy-তে।
একই ঘটনা restaurant-এও হচ্ছে।

অনেক restaurant এখন interior বানাচ্ছে শুধু “ছবি সুন্দর আসবে” এই চিন্তা করে।

ফলে ceiling সুন্দর।
wall সুন্দর।
light সুন্দর।
furniture সুন্দর।

কিন্তু kitchen থেকে table-এর distance?
Waiter movement?
Table turnover?
Privacy?
Acoustic control?
Waiting area?
Family seating?
Couple seating?
Group seating?
এসবের কথা শেষ পর্যন্ত কে ভাবছে?

এখানেই একজন commercial interior designer-এর আসল value।
কারণ আমরা শুধু space সাজাই না।
আমরা space-এর ভেতরে customer behaviour design করি।

আর আগামী দিনে এই বিষয়টা আরও গুরুত্বপূর্ণ হবে।
কারণ customer এখন শুধু product কিনতে যায় না।
সে experience কিনতে যায়।

একটা restaurant-এর খাবার ভালো হলেই হবে না - experience ভালো হতে হবে।
একটা fashion store-এর কাপড় ভালো হলেই হবে না - shopping experience ভালো হতে হবে।

একটা office সুন্দর হলেই হবে না- employee productivity আর client experience-এর কথাও ভাবতে হবে।
এখন প্রশ্ন হচ্ছে—
বাংলাদেশের business owners কি interior-কে expense হিসেবে দেখবেন, নাকি investment হিসেবে?

আমার মনে হয় এখানেই আগামী কয়েক বছরের বড় পরিবর্তনটা আসবে।
যারা শুধু “সুন্দর interior” বানাবে, তারা অনেকের সঙ্গে compete করবে।
কিন্তু যারা brand + customer experience + business performance একসঙ্গে design করবে, তারা আলাদা হয়ে যাবে।

কারণ শেষ পর্যন্ত একটা commercial space-এর সাফল্য দেয়ালের সৌন্দর্যে মাপা হয় না।

মাপা হয়-
মানুষ কতক্ষণ থাকে।
কতবার ফিরে আসে।
কত বেশি কিনে।
কত সহজে জায়গাটা মনে রাখে।

আর সবচেয়ে গুরুত্বপূর্ণ-
interior design করার পর businessটা কতটা ভালো perform করে।

লিখে রাখেন - আগামী দিনের commercial interior design হবে শুধু “কেমন দেখায়” সেটা নিয়ে না।
হবে - এই space-টা business-এর জন্য কতটা কাজ করে” - সেটা নিয়ে।
