A practical guide to creating professional 2D and 3D floor plans online — from uploading an existing plan to designing from scratch.
You have two starting points: (A) Upload an existing floor plan — if you have a sketch, PDF, or DWG file from a previous design or client, upload it to an AI tool that converts it to a digital format automatically. This is the fastest method. (B) Draw from scratch — use the online editor to place walls, doors, windows, and rooms. Modern AI tools have smart snap features that make this fast even without architectural training.
Before placing any rooms, set your site dimensions. A standard Indian 2BHK is typically 800–1,200 sq ft (74–111 sq m). A 3BHK ranges from 1,200–1,800 sq ft. Set your scale early — most tools use millimetres or metres for professional accuracy. Standard wall thickness in Indian residential construction is 230mm (9 inches) for exterior walls and 115mm (4.5 inches) for interior walls.
Start with the structural walls — exterior walls first, then interior room dividers. Place rooms in logical order: living areas at the entrance, bedrooms in the private zone, kitchen in the east or south-east per vastu, and bathrooms in the west or north-west. Use the snap-to-grid feature to keep walls aligned. Most professional tools allow you to see the room area update in real time as you adjust walls.
Place doors with careful consideration for vastu: the main entrance should ideally face north, east, or north-east. Internal doors should open into rooms, not corridors. Windows should be placed on exterior walls in the north or east for maximum natural light. Standard door widths in India: main door 1,050–1,200mm, internal doors 900mm, bathroom doors 750mm.
This is where modern AI floor plan tools dramatically accelerate the workflow. Once your 2D floor plan is complete, click the 3D convert button. In Zlendo Realty, this takes under 60 seconds — the AI reads the wall placements, door and window positions, and generates a full navigable 3D model. Traditional tools require manual extrusion and 3D modelling, which takes hours. The AI conversion also calculates room volumes, which feeds directly into the cost estimation tool.
With the 3D model ready, place furniture from the catalog. Start with the largest pieces (sofas, beds, dining tables) and work down to smaller items. For a realistic presentation, add ceiling heights (standard 2,750mm in India), flooring materials, and wall finishes. Vastu-aware furnishing tips: avoid placing beds under beams, keep the north-east corner light and uncluttered, and position the master bedroom in the south-west.
Once you're satisfied with the layout and furnishings, generate photorealistic renders. AI render tools like Zlendo Realty's 60-second render engine produce client-ready images without any lighting setup. Share with clients via a direct link — no download required. For presentations, export the floor plan as a PDF or image alongside the renders and any vastu compliance report.
