Our Services

Building design, 3D modelling & construction services

Every plot of land and household requirement is different. Rather than publishing generic fixed-price packages, we discuss your specific land dimensions, functional needs, and site conditions so you know exactly what each stage entails.

Architectural Plans, Structural & Working Design

Architectural floor plans, structural engineering drawings, and electrical & plumbing design tailored to your plot

Every successful residential or multi-storey building starts with a well-proportioned floor plan and sound structural design. At NK Building Design & Construction, we work closely with landowners to prepare architectural plans, structural drawings, electrical and plumbing layouts, and municipal plan submission drawings.

Multi-storey residential building 3D exterior design visualization

What this service involves

Architectural floor-plan layout based on plot dimensions, orientation, road access, and family room requirements.
Structural design and reinforcement detailing aligned with the intended number of storeys and site parameters.
Coordinated electrical and plumbing design along with project estimating and costing discussions.
Municipal plan approval process assistance—preparing required submission drawings and guiding landowners through the application steps (without guaranteeing authority approval).

Information to prepare before we talk

Approximate land dimensions or plot area (in Decimal, Katha, Square Feet, or Length × Width in feet).
Direction and width of the adjacent access road(s) and notable surrounding structures.
Intended number of floors, units per floor, and specific room requirements for your family or tenants.
Any existing land sketch, digital survey sheet, or site photographs you may already have.

How to discuss your requirements

You can initiate a design discussion by visiting our Chandanaish office (Gachbaria, Khanhat) or our Chattogram construction office (2nd Floor, Chawkbazar), or by calling / messaging us on WhatsApp.

3D Modelling & Exterior Visualization

Visualize your building facade, roof profile, balconies, and material palette in 3D before construction begins

Two-dimensional floor plans alone rarely convey how a home will look and feel from the street. Our 3D modelling and exterior visualization service translates your floor plan into a clear perspective rendering so you can review proportions, facade materials, and architectural details before breaking ground.

Two-storey residential building 3D design visualization by NK Building Design & Construction

What this service involves

Development of a 3D exterior model directly aligned with your building floor plan and plot frontage.
Architectural detailing of entrance porticos, balcony railings, window bays, roof parapets or pitched eaves, and boundary gates.
Exploration of exterior finishes—including paint palettes, brick or stone cladding textures, and decorative screen elements.
Collaborative review of the visualization so adjustments to the facade can be resolved prior to site execution.

Information to prepare before we talk

An existing floor plan or architectural layout (or we can develop the floor plan and 3D exterior together).
Any visual preferences regarding architectural style—such as a columned portico, contemporary geometric framing, or classic brickwork.
Details on front setback space, boundary wall/gate needs, and rooftop usage.

How to discuss your requirements

Browse our published design visualizations to see examples of our exterior work, then reach out with your plot details or floor plan to discuss a custom 3D exterior concept.

Building Construction, Site Survey, Soil Testing & Supervision

From digital land survey and soil investigation to methodical on-site construction and structural supervision

Sound architectural drawings require accurate site data and disciplined execution on site. NK Building Design & Construction undertakes digital survey, soil testing coordination, estimating and costing, and building construction & supervision across Chandanaish and the wider Chattogram region.

What this service involves

Digital land survey to verify plot geometry and levels, alongside soil testing to inform safe foundation design.
Detailed project estimating and costing (material quantities and stage-wise cost breakdowns) aligned with the working drawings.
Hands-on verification of foundation groundwork, column starter bars, beam reinforcement cages, and slab shuttering before concrete casting.
Flexible engagement scope—whether you want to discuss full building construction or periodic on-site engineering supervision.

Information to prepare before we talk

Exact project location (area, upazila/municipality, and district) and site access conditions for material delivery.
Whether you already have architectural and structural drawings or need design and construction together.
Your preferred scope—digital survey, soil testing, estimating & costing, full construction, or engineering supervision.
Which floors or phases you plan to build in the initial stage.

How to discuss your requirements

Because every site and structural design differs, we do not publish generic per-square-foot price promises. Instead, we review your drawings and site conditions directly to prepare a clear, realistic estimate and construction plan.

Our Complete 9 Building Design & Engineering Services

NK Building Design & Construction provides and coordinates the following nine core services from initial site measurement to construction supervision:

01. Architectural Plans

Thoughtful 2D floor plans, room layouts, and spatial organization tailored to your plot dimensions and household needs.

02. Structural Design

Structural engineering calculations and reinforcement detailing for foundations, columns, beams, and slabs.

03. Electrical & Plumbing Design

Coordinated working drawings for electrical distribution points, lighting layouts, water supply, and sanitary drainage lines.

04. 3D Modelling

Three-dimensional exterior modelling and perspective visualizations so you can review the building appearance before construction.

05. Soil Testing

Sub-soil investigation and bearing-capacity testing coordination to determine safe foundation requirements for your plot.

06. Digital Survey

Precision digital land surveying to record exact plot boundaries, angles, road alignments, and ground elevation levels.

07. Estimating & Costing

Preparation of material quantity take-offs and realistic stage-by-stage construction cost estimates based on your drawings.

08. Building Construction & Supervision

On-site construction execution and regular engineering supervision during foundation, reinforcement, and casting stages.

09. Municipal Plan Approval Assistance

Preparation of required submission sheets and procedural assistance for municipal plan applications (final approval rests with the relevant authority).

Transparent & Realistic Consultation

Construction costs, design schedules, and municipal plan approval procedures depend on plot location, soil conditions, building height, and applicable regulations. We assist with preparing municipal submission drawings and application steps, without making unsupported price promises or guaranteeing authority approvals.
