RESIDENTIAL
RESIDENTIAL • Shokipur, Tangail

5 Katha Duplex Villa

Tropical Modern Architecture: A multi-tiered, pitched roof layered with classic terracotta tiles provides excellent weather resistance while delivering a timeless aesthetic perfectly suited for the Bangladeshi climate. Earthy Material Palette: The facade balances smooth, off-white textured plaster with strategically placed exposed brick columns and accents, creating a warm, grounded visual contrast. Seamless Indoor-Outdoor Flow: Expansive floor-to-ceiling glass sliding doors on both the ground and first floors flood the interior with natural light and allow for optimal cross-ventilation. Extensive Open-Air Living: A deep, continuous first-floor balcony with slatted wooden railings and a spacious upper-level open terrace offer generous spaces for outdoor relaxation and unobstructed views of the surrounding greenery. Optimized Plot Utilization: The 5-katha layout efficiently integrates a deep, sheltered car porch directly into the ground floor footprint, maximizing utility without sacrificing aesthetic appeal. Integrated Landscape Design: The hardscaped stone driveway is softened by dense, manicured tropical landscaping, featuring native trees, vibrant bougainvillea draping the boundary walls, and a lush front lawn that enhances privacy and curb appeal.

Direct Answer: To calculate your flat interior budget in Dhaka, multiply your carpet area by the chosen finish grade, then factor in structural additions like false ceilings, full modular kitchens, and custom wardrobe walls.

  • 2,000 SFT Flat (Luxury Finish): ~৳45 Lakhs – ৳55 Lakhs (includes full drawing, dining, master suite, children's bedroom, kitchen, and false ceilings).
  • 3,500 SFT Flat (Signature Luxury): ~৳75 Lakhs – ৳95 Lakhs (natural teak veneer, imported German hardware, quartz tops, and ambient lighting).
  • 5,000+ SFT Duplex (Ultra Prestige): ~৳1.3 Crore – ৳2.0+ Crore (Italian marble flooring, double-height feature walls, smart automation, and bespoke furniture).

Direct Answer: Unregulated contractor estimates in Bangladesh frequently omit critical installation items, resulting in 25% to 45% post-contract budget escalations.

  • Generic Hardware Substitution: Quoting for Blum/Hafele but fitting unbranded Chinese hardware on site.
  • Omitted Electrical Rewiring & Breakers: Charging extra mid-project for essential electrical load balancing and conduits.
  • Substandard Paint & Surface Prep: Applying a single coat of low-grade paint without proper anti-damp primer treatment.
  • Hidden Site Supervision & Logistics Fees: Extra billing for debris disposal, scaffolding, and transportation. Interior Knowledge provides 100% fixed-price guarantees.

Direct Answer: A standard 2,000 to 3,500 sqft apartment interior in Dhaka takes 60 to 90 working days from design sign-off to handover. Large duplex villas (4,000 to 7,000 sqft) require approximately 90 to 120 working days.

  • Days 1–15: 3D visualization, material sample sign-offs, and site mobilization.
  • Days 16–45: Civil modifications, electrical conduits, false ceilings, and factory joinery fabrication.
  • Days 46–75: Cabinetry installation, marble polishing, primer, and surface paint coats.
  • Days 76–90: Decorative fixtures, lighting calibration, deep cleaning, snag audit, and formal handover.
