Everything you need to develop your floor plan.
Work on the layout, arrange furniture and choose finishes in one project. Review your decisions in 2D and 3D, then prepare drawings and images to share.
Drawing, furnishing, finishing one surface at a time, 3D and every export are free, with no watermark and no account. Gridsnap Pro adds tools that coordinate and compare: generated layouts, room kits, finish schemes, design options, automatic dimensions, additional checks and unlimited synced projects. Each section says which is which.
Make the space work
Walls, doors, windows, rooms and storeys to exact sizes, and how they connect.
Draw to exact sizes, click and type
Click a corner, type the length and angle, press Enter: the wall lands at that millimetre. Doors and windows snap into the wall and cut a real opening. Already have a plan? Trace a photo, scan or PDF after setting its scale against one known distance.
- Typed lengths and angles are exact, not suggestions
- Snapping to corners, midpoints, alignments and wall extensions, with casually drawn walls kept straight
- Clean mitred corners and T-junctions, solved for you
- Doors, sliding doors, cased openings and windows in many shapes
- Trace mode over an imported image or PDF
More detail
- Reference points: start a wall at an exact offset from existing geometry
- Door frames drawn properly: jamb posts, leaf thickness, swing arc, flush-to-face alignment
- Holes and niches cut into a wall, shaped in the panel
- Structure tool for chimneys and square or round columns
Rooms, areas and dimensions
Rooms are found from the walls and labelled with their net floor area, measured to the inner wall faces. Dimensions attach to corners and openings and update when the drawing changes.
- Automatic room detection with net m² (or ft²)
- Room schedule on the PDF
- Dimensions anchored to corners, jambs and points along a wall
- Automatic plan and elevation dimensions with Pro, reviewed before they are added
Storeys, stairs and basements
Add storeys above, or below for a basement. Stairs are parametric and cut their own opening through the floor they arrive at, and another storey can show faintly underneath while you draw, so walls line up through the building.
- Unlimited storeys, above and below ground
- Straight, L- and U-shaped stairs, with winders and landings
- Stair openings cut automatically, with headroom checked
- Split levels, lofts and guarding
Roofs
Drag a rectangle over the building and pick a form. Ridges, hips and valleys draw themselves in plan, the 3D roof has real thickness and overhangs, and walls rise to meet its underside, so a gable end is a wall you can put a window in.
- Gable, hip, pyramid, half-hip, gambrel, mansard, mono-pitch, butterfly and flat with parapet
- Pitch, eaves height, overhang and thickness per roof
- Overlapping roofs merge with proper valleys
- Skylights, and tile or standing-seam coverings
Terraces, decks and the site
Draw a deck the way you draw walls; it lands a step below the floor with boards, railings and steps that size themselves from the real height. Set the ground level, shape uneven terrain, and add paths, fences and pools.
- Terraces with steps and railings on the edges you choose
- Ground level, plinth and uneven terrain from a grid of heights
- Surface finishes, fences, gates and pools
Find out what fits
Real furniture sizes in the real room, in plan and 3D.
Furniture at the sizes you need
Search the catalogue, drop an item in and type its exact size. Sofas, beds, cabinets and fixtures back up against the wall they belong on, kitchen units snap into runs, and everything appears in 3D, so you can rearrange a room and see it from inside before you buy anything.
- A searchable catalogue for living, dining, bedrooms, kitchens, bathrooms, saunas, technical rooms and gardens
- Every item resizes to typed dimensions
- Wall snapping and furniture-to-furniture snapping for cabinet runs
- Measure the gap between any two items with the dimension tool
- Move by a typed distance, rotate as a group, and pick stacked items one by one
More detail
- Kitchen and bathroom fittings modelled with real bowls, taps and fronts
- Kitchen cabinets in flat, shaker or raised-panel fronts, with bar, long bar, knob, edge-pull or no handles, set for the whole kitchen in one click
- Scale figures for a sense of size
- Repeat an item along a line, a grid or a ring, and lighting layouts over a room
- The free plan check flags furniture standing in a wall or a doorway; Pro checks clearances, door swings and routes
- Furnish room (Pro): a full layout for a named room, which you then adjust
- My Library (Pro): save a sized, finished piece or a whole set, such as a kitchen run or a living-room group, and place it in any project
See the choices together
Floors, walls and furniture in the materials you are considering, in the plan and in 3D.
Materials for floors, walls and furniture
In the Finishes activity a click picks a surface: a room’s floor, one face of a wall, or one part of a piece of furniture. Choose a material from the built-in shelves or the Gridsnap texture library and it shows in the Textured plan and in 3D at its real size.
- Room floors with a laying direction, and finish areas for part of a room
- Whole rooms, single wall faces and accent walls
- Supported furniture parts, such as upholstery, frames, worktops and cabinet fronts
- Doors, windows and stairs
- Project defaults, and a review that finishes every exterior wall at once
More detail
- Paint: load one material and click every surface it goes on
- “Used in this project” lists each material and where it is, for reuse
- Library textures go on floors, walls and furniture parts; you cannot upload your own textures
- Finishes describe appearance: they change no area, quantity or check, and they are not prices or product specifications
Room kits
A room kit is a set of floor, wall, joinery and furniture finishes chosen to go together. With Pro, preview one on the rooms you pick, see exactly what changes and what stays, and apply it in one step you can undo. A kit finishes what a room already contains; it does not add or arrange furniture.
- Three built-in kits, free to browse with their materials
- Preview on chosen rooms, with every change listed first
- Save a room’s finishes as your own kit and reuse it
Finish schemes
A finish scheme saves this project’s finishes under a name, so you can try an alternative, compare the two side by side and put either back. A kit is a set of materials for any room; a scheme is the record of this project’s own rooms.
- Save the whole project or chosen rooms
- Preview a scheme with every change listed, then apply it in one undoable step
- Compare plans side by side with the finishes that differ, room by room
- Saved schemes stay viewable, renameable and deletable without Pro
Check the design, then share it
Look at the project from every side, check it, and prepare drawings and images for someone else.
3D, elevations and sections
Every plan is also a 3D model, four elevations and any section you cut. In 3D choose Diagram, Clay or Realistic, where finishes are textured with sun and shadows; cut the storey away at hip height to look into the rooms, save named views to come back to, or walk through.
- Live 3D, synced with the plan as you edit
- Diagram, Clay and Realistic styles, with daylight or interior light
- Saved views with camera, storey and display settings
- North, south, east and west elevations, and section drawings
- First-person walkthrough that opens doors as you reach them
Textured plans, legends and finish schedules
The plan has two styles. Technical is the measured line drawing; Textured draws each floor, wall face and furniture part in its finish, under the same linework and labels. Both export, and a Textured sheet can carry a finish legend. Tables → Finishes lists every room’s finishes with a code, which also prints as a finish schedule.
- Technical or Textured on screen, in PDF and in PNG
- Finish legend beside the drawing, with matching codes
- Finish schedule: each room’s floor and walls with their source
- CSV of the finishes table
More detail
- A Textured PDF keeps lines and text as vectors; the texture fills are images
- A finish schedule describes appearance. It is not a construction specification, a takeoff or a price list
Plan check
Rules read the geometry as you draw and mark each finding at its spot on the plan. The mechanical mistakes, such as furniture inside a wall or doorway or two openings cut into each other, are checked free. Pro adds checks on door swings, routes, clearances, daylight and kitchen and bathroom practice, plain-language explanations and one-click fixes where the repair is unambiguous.
- Findings counted live, each one a click from its spot
- Dismiss what you disagree with; it stays dismissed
- Free users see how many Pro findings a plan has, by category
- These checks help you review a drawing; they do not establish code compliance
Drawings, images and files
Export a PDF at a true scale with a title block, a layered DWG or DXF for CAD, a PNG, or an overhead render of a furnished storey. The measured outputs and the presentation image are different things, and each says which it is.
- PDF at 1:20 to 1:2000 on A4 to A0: Technical sheets are vector; Textured sheets keep vector lines and text with image texture fills
- Plans, elevations, sections and finish schedules on one sheet set
- AutoCAD 2018 DWG or DXF with layers and real dimension entities, plus a legacy R12 DXF
- PNG, and an overhead render as PNG or a one-page PDF
- No watermarks
More detail
- Model space at 1:1 in millimetres, with a paper layout per sheet
- Plot window: print a dragged area of the plan
- An overhead render is not a scaled drawing and not an editable 3D model
- DWG output has been checked in open-source readers; it has not been opened in AutoCAD itself
AI presentation images
Turn a 3D view, a saved view or a storey seen from above into a realistic presentation image. Choose how closely it follows your design and the mood of the light; your plan stays unchanged, and you can compare the image with the view it came from. Images are AI-generated, so details may differ from your design.
- As designed, Lived-in, or Explore a style with three palettes
- Neutral daylight, Warm and inviting, or Soft evening
- Compare each image with its source view, then download it
- Subscriptions include a monthly number of images; extra images can be bought once
More detail
- Nothing in an image is applied to the plan
- Not to scale and not exact: use the PDF or DWG for anything measured
- No photo upload, text prompts, 360° panoramas or video
Layers and print control
Everything you draw already belongs to a layer by what it is, and you can add your own. Each layer has two switches, visible while editing and included in print, so a permit set without furniture or a furnishing plan without dimensions is two clicks, and the drawing itself never changes.
- System layers for walls, structure, stairs, roofs, furniture, rooms, dimensions and more
- Custom layers for existing versus proposed, or phases
- Separate print switch per layer, honoured in PDF, PNG, DWG and DXF
Begin where you are, keep it safe
Optional starting workspaces, and where your projects live.
Space Planning: rooms before walls
List the rooms with their sizes and connections, arrange them as spaces, and build the arrangement into ordinary walls, rooms and doors in one step. With Pro, describe the home in your own words and compare generated layouts, each checked before you see it.
- A room list with target sizes, connections and privacy
- Draw spaces by hand and check them against the list
- Build plan: walls, named rooms and planned doors in one undo step
- Pro: generated layouts, more layouts on request, and AI reading of a description
Massing: shape the building first
For when the open question is the building rather than the rooms: footprints, storeys and setbacks to exact sizes, repeated storeys and façade rules, then ordinary walls and floors created in the drawing.
- Rectangle, polygon, courtyard and push/pull, every size typed
- Storeys with their own heights, and repeated storey sequences
- Create drawing, then Finish in Drawing to keep the shape as a reference
- Opening Massing, the example, Finish in Drawing and every Drawing edit are free
Where projects are saved
Plans are saved in your browser on your device, with no account needed. Sign in for free and one project syncs to your account and opens on any computer; Pro syncs every project and keeps its version history. Save a .gridsnap.json file whenever you want your own backup.
- Unlimited local projects, with no account
- Free account: one synced cloud project
- Pro: unlimited synced projects and cloud version history with restore
- Conflict protection when the same plan is open twice
- Library textures, sync and AI tools need a network connection
Workflow
Keyboard shortcuts for every tool, an undo history that names each step, copy and paste that carries doors and windows with their walls, arrow-key nudging, and tabs for several open plans.
- Keyboard shortcuts for all tools
- Undo and redo, each step named
- Copy, paste and duplicate, across storeys too
- Several plans open in tabs
