Building Design in 60 Seconds
Building design is the process of planning a building and describing it in drawings and models clearly enough that it can be approved, priced, built on site and used comfortably by the people inside. It moves through stages: understanding the brief and site, developing a concept, planning spaces and floors, designing elevations, coordinating structure and services, producing working drawings and 3D visuals, and preparing construction and approval documents. Today most of this is done with software such as AutoCAD, Revit, SketchUp and rendering tools, increasingly through BIM (building information modelling).
- Main goal
- A building that works, stands and can be built
- Key outputs
- Plans, elevations, sections, 3D, working & approval drawings
- Core software
- AutoCAD, Revit, SketchUp
- Visualisation
- Lumion, Enscape, V-Ray, Twinmotion
- Works with
- Architects, structural & MEP engineers
- Career entry
- Draughtsman, Revit modeller, visualiser
Key takeaways
- Building design is about function, safety, buildability and approval, not just looks.
- It follows clear stages, from brief to approval drawings.
- Designers coordinate with structural and MEP engineers throughout.
- BIM is changing how buildings are documented and coordinated.
- Sustainable design is becoming a basic expectation.
- You can learn it after 12th, a diploma or a degree.
Building Design Meaning
Building design (noun): the planning, drawing, modelling and documentation of a building so that it meets the client's needs, follows building rules, can be built safely and economically, and is comfortable to use.
Every building design answers three questions
- 🧩Will it work?Rooms, sizes, circulation, light, air and how people use the space.
- 🏗️Will it stand?Structure, foundations and services coordinated with engineers.
- ✅Can it be built and approved?Clear drawings, building rules, budget and site practicality.
Who does what in a building project
From Temple Treatises to BIM
Building design is old; the tools are what keep changing.
- 🛕Ancient & medievalRules of proportionSouth Indian texts such as the Manasara and Mayamata set out planning rules; Thanjavur's Brihadisvara Temple (11th century) shows that precision.
- ✏️Until the 1980sDrawing boardsPlans drawn by hand with T-squares, set squares and tracing paper.
- 🖥️1982 onwardsCADAutoCAD brings drafting to personal computers, making drawings fast to copy and revise.
- 🏢2000s onwardsBIMRevit, first released in 2000, models real building elements that carry data.
- 🤖TodayReal-time & AIInstant renders, cloud collaboration and AI-assisted concepts.
Why Good Building Design Matters
- 🛡️SafetyCoordinated structure, exits, stairs and services protect the people inside.
- 💰CostClear drawings cut site mistakes, waste and rework, saving money.
- 🌞ComfortOrientation, daylight and ventilation make spaces pleasant and cheaper to run.
- 📋ApprovalsDesigns that follow building rules get approved with fewer delays.

See the courseHow Building Approval Works (Overview)
A general overview. Exact steps and fees depend on your local authority and the current rules.
- Check the rulesSetbacks, FSI, height, parking and road width for the plot.
- Prepare drawingsSite plan, floor plans, elevation, section and area statement.
- Professional sign-offA licensed architect or engineer signs the drawings.
- SubmitApply to the local body or planning authority, often online.
- ScrutinyOfficials check the drawings against the rules.
- CorrectionsRevise drawings if the authority asks.
- Permit issuedConstruction can start as approved.
- CompletionSome projects need a completion or occupancy certificate.
In Tamil Nadu, building plans follow the Tamil Nadu Combined Development and Building Rules and the local planning authority's requirements, alongside the National Building Code of India. Always check the latest version before a project.
Residential, Commercial, Industrial & Institutional
Each building type changes what the designer must prioritise.
- 🏠ResidentialHouses, villas and apartments where privacy, light and budget lead.
- 🏬CommercialShops, offices and hotels where frontage, flexibility and parking matter.
- 🏭IndustrialFactories and warehouses with large spans, loading and safety needs.
- 🏫InstitutionalSchools and hospitals where circulation and accessibility are critical.
Example: a 30 × 40 ft house plot in Saravanampatti and a G+4 apartment on Avinashi Road both need plans and approvals, but the apartment adds lift cores, parking, fire exits and repeated floor layouts.
Designing Buildings That Use Less and Feel Better
Sustainable design starts on the drawing board, long before solar panels are added.
- 🧭OrientationPlace long walls north–south and shade the west to reduce heat gain.
- 🌬️Cross-ventilationOpenings on opposite walls let breezes cool rooms naturally.
- ☀️DaylightWell-placed windows and light shelves cut daytime lighting use.
- 💧WaterRainwater harvesting, efficient fixtures and greywater reuse.

What is Building Design: 76 Questions Answered
Basics
Building design is the process of planning a building and describing it in drawings and models clearly enough that it can be approved, priced, built and used comfortably.
It means deciding how a building will work, look and be built, and communicating that through plans, elevations, sections, 3D models and documents.
A building designer turns a client's needs into plans, elevations, sections, 3D models and working drawings, usually working with architects and engineers.
They overlap, but in India the title architect is protected under the Architects Act, 1972 and needs a recognised degree and Council of Architecture registration. Building designers plan and draw buildings, often within architecture and engineering teams.
No. Civil and structural engineers make sure the building stands safely; building design focuses on planning, drawings and visualisation. The two work closely together.
The part of building design concerned with spaces, form, appearance and how people use the building, as opposed to structural or services design.
Arranging rooms, circulation, light and ventilation on a plot so the building works well and meets local rules.
Site plan, floor plans, elevations, sections, details, working drawings, schedules and, for approval, an area statement.
A plan is a view from above; an elevation is a straight view of one face; a section is a vertical cut through the building.
A professional who plans buildings and prepares their drawings, models and presentations, usually working alongside architects and engineers.
A training programme that teaches building planning, drawings, BIM and rendering with software such as AutoCAD, Revit and SketchUp, ending with a portfolio of projects.
Good design makes buildings safe, comfortable, affordable to build and run, easier to approve and pleasant to live or work in.
Process
Brief, site analysis, concept, space planning, floor planning, elevation design, structural and MEP coordination, working drawings, 3D visualisation, construction documentation and approval drawings.
Understand the brief and site, explore concepts, plan spaces and floors, design elevations, coordinate structure and services, then produce drawings, visuals and approval documents.
Studying the plot's size, shape, road access, orientation, levels, soil, surroundings, sun and wind before designing.
Arranging zones and rooms so movement is easy and related spaces sit together, for example kitchen next to dining.
The early stage of exploring ideas for form, layout and character, usually with sketches and quick 3D models.
Working with the structural engineer so columns, beams and slabs fit the design and the building is safe.
Planning electrical, plumbing, drainage, HVAC and fire services so they fit the building without clashing with structure or each other.
Turning the zoning into accurate, dimensioned plans with walls, doors, windows, stairs and furniture.
Designing how each face of the building looks: openings, materials, sunshades and proportions.
Detailed, dimensioned drawings that site teams use to build.
The complete set of drawings, details, schedules and specifications needed to tender and build a project.
Renders and walkthroughs help clients understand and approve a design before construction starts.
It depends on size, changes and approvals. A simple house can take a few weeks of design work; larger or more detailed projects take longer.
A written summary of the client's needs, budget, timeline and expectations.
Approvals
Drawings are prepared in the local authority's format, checked against building rules such as setbacks, FSI and parking, signed by a licensed professional and submitted for permission before construction.
A registered architect or licensed engineer or surveyor, as required by local rules.
Projects follow the Tamil Nadu Combined Development and Building Rules and the local planning authority's requirements, along with the National Building Code of India. Always check the latest version.
Open spaces required between a building and its plot boundaries; they depend on plot size, road width and building height.
Floor space index: the total built-up area allowed divided by the plot area.
They prepare the drawings; a licensed professional signs and submits them.
Building types and sustainability
Designing homes such as independent houses, villas and apartments, focusing on privacy, daylight, ventilation and budget.
Designing shops, offices, malls and hotels, focusing on frontage, flexible floors, parking and services.
Designing factories and warehouses with large spans, loading areas, safety and space for machinery.
Designing schools, colleges and hospitals, where circulation, accessibility and safety are key.
Designing buildings that use less energy and water, use materials responsibly and stay comfortable with less mechanical cooling.
Designing to green building standards, often assessed in India by rating systems such as IGBC and GRIHA.
Orient it well, shade west-facing walls, use cross-ventilation, sunshades, light-coloured roofs and good insulation.
Climate-responsive design, open and flexible layouts, natural materials, BIM-based delivery, real-time visualisation and smart building systems.
A building that uses sensors and connected systems to manage lighting, cooling, security and energy automatically.
Software and BIM
AutoCAD for drafting, Revit for BIM, SketchUp for 3D concepts, Lumion, Enscape, V-Ray or Twinmotion for rendering, Navisworks for coordination and Photoshop for presentation.
Building information modelling: creating a 3D model of a building where every element carries information, so drawings, schedules and coordination come from one source.
CAD draws lines that represent a building; BIM models real elements with data, so changes update everywhere.
Modelling buildings in BIM and producing coordinated plans, sections, schedules and sheets.
2D drafting of plans, details, working drawings and approval drawings.
Quick 3D concepts, massing studies and 3D elevations.
Combining models from different disciplines, checking clashes and reviewing projects.
A real-time rendering tool from Epic Games, used for visuals and walkthroughs, similar in purpose to Lumion and Enscape.
They do different jobs. AutoCAD is fast for 2D drawings and approvals; Revit is better for BIM models and large, changing projects. Most designers use both.
Lumion and Twinmotion suit walkthroughs, Enscape suits quick reviews inside Revit and SketchUp, and V-Ray suits detailed photoreal stills.
AutoCAD first, then SketchUp, then Revit, then a render engine.
AI helps with concept images, render enhancement, early massing studies and writing reports, but designers still check rules, structure and site conditions.
Learning and careers
Students after 12th, diploma holders, civil and mechanical engineers, interior designers, architecture students and career changers.
Many students first take a Diploma in Civil or Architecture after 10th, then add building design software and skills.
No. Building drawings are technical and made in software; practice matters more than artistic talent.
Basic maths for measurements, areas and scales is enough.
Planning sense, drawing accuracy, software skills, understanding of building rules, attention to detail and clear communication.
No specific degree is needed for draughtsman and modeller roles; a structured course and a strong portfolio matter most. Architect and engineer titles need the relevant degree.
It takes steady practice rather than talent. AutoCAD is quick to start; Revit takes longer because you learn how buildings fit together.
Architectural draughtsman, building designer, Revit or BIM modeller, 3D visualiser, approval drawing specialist and, with experience, BIM coordinator.
Architecture firms, builders and developers, civil and MEP consultants, BIM outsourcing companies, contractors, interior studios and visualisation studios.
Indicatively, freshers in Coimbatore often start around ₹12,000 to ₹25,000 a month, with Revit and BIM roles at the higher end; pay grows with experience.
Yes for people who enjoy planning spaces, detail and software. Construction keeps creating work, and BIM skills are increasingly valued.
More BIM, real-time visualisation, AI-assisted design and sustainable buildings, with steady demand from construction and overseas BIM work.
Yes. Freelancers prepare house plans, 3D elevations and renders, usually after gaining some job experience.
Many Revit and BIM professionals work with firms in the Middle East, UK and Australia after building experience.
A structured course of about 6 months can make you job-ready for junior roles; you keep learning on the job.
Learning only software buttons, skipping drawing basics, ignoring building rules, messy files and a portfolio of exercises instead of complete projects.
Include 6 to 8 complete projects with plans, sections, a Revit model, renders and short explanations.
