Architectural design
Concept, planning and detailed architectural design for new buildings, extensions and refurbishments.
- Site and massing studies

- Elevations, sections and details
We design buildings and see them built.
Architectural, structural, interior and MEP design for residential, commercial and industrial projects in Bangladesh.
The architecture and development company of LnS Group, working from Banani, Dhaka.
4S Design n Development Ltd. works across architectural, structural, interior and MEP design, and manages development and construction for owners in the residential, commercial and industrial sectors. Our sister company Line n Shape Ltd. has built civil, steel and electrical projects since 2015, and that site experience informs every drawing we issue.
Industrial
Factories, warehouses and steel framed sheds, with the structure and the services designed together.
Commercial
Offices, showrooms and retail spaces, from shell and core through to a finished fit-out.
Residential
Houses and apartment buildings, from a single plot study to a completed block.
- Design and build in one team. Architects, engineers and construction managers work from the same drawings from the first sketch.
- Drawings that can be built. Every design is checked against structure, services and site method before it is issued.
- Clear communication. One point of contact, a written scope, and progress you can see at every stage.
- Scope and fees in writing. Scope, fees and programme are agreed in writing before design work starts.

Four stages, each with a defined output and a sign-off before the next begins.
Concept
We visit the site, read the brief and the budget, and test massing and layout options until one direction is agreed.
Agreed concept and outline budget
Design
Architecture, structure, interiors and services are developed together, so the scheme that is approved is the scheme that can be built.
Coordinated design set for approval
Documentation
Construction drawings, specifications, schedules and quantities are prepared for authority submission, tendering and site use.
Construction drawings and tender pack
