Pick a common plot size, confirm road and floors, then start with a clean 2D plot, 3D site, boundary wall, gate, and rough budget.
Choose a complete starter design with rooms, walls, openings, structure, 3D objects, and live cost estimates already prepared.

Use this guide when you are deciding where the building should sit, which area should become a room, and which area should be used for structure and estimates.
You are allowed to build somewhere inside this area. It is the plot area left after setbacks and no-build space.
This is the house footprint you are currently planning. It is your chosen building size inside the allowed limit.
This open space stays around the buildable zone for road setback, ventilation, parking, garden, and local rules.
House area is mostly a planning guide and container. The real estimate built-up area mainly comes from the actual rooms, walls, doors, windows, structure, and objects you add, not just the blue guide box.
A 40 x 60 plot is 2400 sq.ft. After setbacks, the green buildable zone may become 1320 sq.ft. You can still choose a smaller blue house area, such as 900 sq.ft, and keep the remaining space for parking, garden, ventilation, or future expansion.
Use Draw Area to mark a 12 x 12 bedroom, an 8 x 10 kitchen, or a 5 x 7 toilet. Then add room walls, doors, windows, and fixtures inside those marked areas.
Select House Area before adding columns, foundation, slab, or roof when you want structure for the whole building. Select a smaller drawn area when you want structure only for that zone.
Select total floors. The app copies the ground-floor slab plan, rooms, walls, columns, beams, openings, staircase, and interior items into editable upper-floor maps.
This permanently deletes the current auto-saved draft and every saved project in this browser, then reloads a fresh default plan.
A 3D construction planner is a browser tool for sketching a home layout, visualizing spaces in 3D, and estimating materials before speaking with a professional. This page keeps the project local in your browser and does not require login.
Start with built-up area, wall length, wall height, openings, flooring, labor rate, and material rates. The calculator combines material, labor, equipment, and other allowances.
The estimate covers bricks, cement bags, sand, aggregate, steel, paint area, flooring area, and door or window counts using editable project assumptions.
The mini 2D plan uses Konva.js for selected wall handles, while the main workspace uses Three.js for a procedural low-poly 3D house with room labels.
Home owners, students, contractors, early-stage builders, and families planning a house budget can use it for rough planning and discussion.
Local soil, structure, foundation depth, design codes, labor availability, quality, wastage, and market rates can change final construction cost.
