Is the Coohom floor planner free?

Yes. The basic floor planner tool is available on the free plan. You can draw walls, add rooms, place doors and windows, and set dimensions without a paid subscription.

Can I import an existing floor plan into Coohom?

Yes. You can import blueprints, sketches, or images and trace over them manually, or use the AI recognition feature to auto-generate the plan.

How do I change measurements from meters to feet?

Click the gear icon in the top-right corner of the floor plan editor. Under 'Units,' select 'Feet' or 'Inches' as your preferred measurement system.

Can I create multi-story floor plans?

Yes. Click 'Add Floor' in the floor plan editor to create additional stories. You can copy the ground floor layout as a starting point for upper floors.

How do I add a garage or outdoor space?

Use the 'Draw Room' tool and select the room type as 'Garage' or 'Outdoor Space.' These areas use different floor materials and are excluded from interior calculations.

Can I collaborate with someone on a floor plan?

Paid plans support sharing projects with collaborators. You can share view-only links on any plan, but editing access requires a team plan.

What happens if I make a mistake?

Use Ctrl+Z (Cmd+Z on Mac) to undo any action. Coohom supports multiple undo levels. You can also use the version history feature to revert to earlier saves.

Can I draw curved walls?

What Is the Coohom Floor Planner?

The Coohom Floor Planner is a browser-based 2D design tool that lets you create accurate, scaled floor plans from scratch. It is the foundational tool in the Coohom platform, and every 3D design, render, and walkthrough starts here. The floor planner uses a grid-based canvas where you draw walls, define rooms, and place architectural elements like doors, windows, and columns.

The interface is designed for beginners. If you have ever used a drawing app or even Microsoft Paint, you will find the floor planner intuitive. Walls snap to grid lines for accuracy, dimensions auto-calculate as you draw, and the system prevents common mistakes like overlapping walls. Professional users will appreciate the precision tools for exact measurements and custom wall thicknesses.

Step-by-Step Tutorial

Step 1: Create a New Project

From your Coohom dashboard, click "New Project." Enter a project name and select "Start from Scratch" as the starting method. You will be placed into the 2D floor plan editor with a blank grid canvas. The default canvas size is generous enough for most residential layouts. If you need more space, the canvas extends automatically as you draw.

Step 2: Draw Exterior Walls

Select the "Draw Wall" tool from the left toolbar (it looks like a pencil with a line). Click on the canvas to place the first wall corner. Move your mouse in the direction you want the wall to go and click again to place the next corner. Continue clicking to outline the exterior perimeter of your building. Close the shape by clicking on the starting point. The wall thickness defaults to a standard residential width, which you can adjust in the properties panel.

Step 3: Add Interior Walls

With the "Draw Wall" tool still active, draw interior walls to divide the space into rooms. Click on an exterior wall to start an interior wall from that point, then click on the opposite wall to end it. Coohom snaps to wall intersections automatically. For rooms that share walls with multiple other rooms, work from the largest spaces to the smallest.

Step 4: Set Room Dimensions

Click on any wall segment to see its length. Click the dimension number to edit it and type the actual measurement. Press Enter to confirm. Coohom adjusts connected walls proportionally. For precise work, use the "Dimension Lock" feature to fix a wall length before adjusting neighbors.

Step 5: Place Doors

Click the "Door" icon in the left toolbar. Browse available door types: single, double, sliding, French, pocket, and more. Click on the door style you want, then click on a wall to place it. The door snaps to the wall and creates an opening automatically. Drag the door along the wall to position it precisely. Use the properties panel to adjust door width and swing direction.

Step 6: Place Windows

Click the "Window" icon in the left toolbar. Similar to doors, browse window types (single-hung, double-hung, casement, bay, skylights) and click on a wall to place. Position and resize using the properties panel. Set the sill height if you plan to render the view from outside.

Step 7: Label Rooms and Save

Click inside each room to see the auto-generated label. Click the label text to rename it (e.g., "Living Room," "Kitchen," "Master Bedroom"). Room type affects AI furniture suggestions later. Save your project with Ctrl+S or the save button. You can now click "Enter 3D" to start furnishing your plan in three dimensions.

Common Mistakes & Fixes

Not closing exterior walls: If the exterior outline is not a closed shape, rooms will not form correctly and you will have issues in 3D mode. Zoom in to verify all corners connect.
Placing doors too close to corners: Doors need clearance to swing open. Leave at least 6 inches (in scale) between a door and a perpendicular wall to allow realistic opening in 3D.
Ignoring wall thickness: Default wall thickness works for most interior walls but exterior walls and load-bearing walls are typically thicker. Adjust thickness for realism.

Pro Tips for Better Results

Start by drawing the exterior outline first, then add interior walls. This ensures proportions are correct before dividing into rooms.
Use the snap-to-grid feature for consistent wall alignment. Hold Shift while drawing to constrain walls to 90-degree or 45-degree angles.
Copy your ground floor layout when adding upper floors to maintain structural consistency, then modify as needed for each story.

Export Options

After completing your floor plan:

2D dimensioned plan: Export as PNG or PDF with measurements shown for construction or planning.
3D mode: Click "Enter 3D" to furnish, render, and create walkthroughs.
Share link: Generate a view-only link to share with clients or collaborators.

Troubleshooting

Walls are not snapping to grid

Check that grid snapping is enabled. Look for the magnet icon in the bottom toolbar and make sure it is active (highlighted).

Cannot place a door on a wall

The wall may be too short for the selected door width. Try a narrower door style or extend the wall. Also make sure you are clicking directly on the wall line, not nearby.

Room labels show "Unknown"

The room may not be fully enclosed. Check for tiny gaps in the walls surrounding that room. Zoom in to 200% and look for hairline openings at wall intersections.
