First-person walkthrough of house and garden
Walk in the browser without any headset: keyboard on desktop, joystick on mobile. Climb the stairs to the second floor, open doors, look out of the windows of the future house.

Landscape Design Software Free Online — 2D & 3D
Draw the plot in 2D and flip it into full 3D with one click: walk the garden and house at eye level, build real terrain from survey heights, check the water level — right in the browser, VR included.
3D garden design that stays a real drawing
It is not a render for show: every object keeps real dimensions, so the beautiful 3D picture is still a working site plan.

How to design a landscape in 3D
-
1
Draw the 2D plan
Plot boundary, house, fence, trees, paths — everything in real metres, with snapping and sanitary-zone checks.
-
2
Switch to 3D
One click — and the flat drawing becomes a 3D scene: buildings get roofs and materials, plants get realistic crowns, fences get their real construction.
-
3
Walk through it
First-person mode at eye level: check the view from the porch, the shade of the future trees, the width of the paths.
-
4
Keep editing anywhere
Move and create objects directly in 3D or VR — the 2D plan stays in sync. Export a to-scale PNG/PDF when you are done.
Real terrain and water level
Add height marks from a survey and 3D builds the actual slope of your land. Set the construction zero level and the water level to plan flooding protection, a lake-side house, piers and bridges.
VR: stand inside the future garden
Open the scene in a WebXR headset straight from the browser — no app install. Walk the paths, feel the real height of the fence and the house, and even move objects with the controllers.
Your own 3D models
Import GLB models — a specific gazebo, a designer bench, your future house from an architect — and they take their real size on the plan and in the scene.

FAQ
Can I install gardmi as an app on my phone?
Yes. gardmi installs straight from the browser, without App Store or Google Play: on Android and in Chrome or Edge on a computer press “Install the app”, on iPhone open the site in Safari and choose Share → Add to Home Screen. The app opens full-screen from its icon and keeps the same cloud projects.
Is the 3D landscape design software free?
Yes. The 3D view, first-person walk mode, terrain and VR are part of the free gardmi editor — no card, no trial timer.
Do I need to model in 3D by hand?
No. You draw a normal 2D plan — walls, fences, trees, paths — and gardmi builds the 3D scene automatically. Edits work in both directions: move an object in 3D and the plan updates.
Can I walk through the site at eye level?
Yes. Switch to first-person walk mode: keyboard on desktop, on-screen joystick on mobile. You can climb stairs, open doors and check views from windows before building.
Will 3D work on my phone?
Yes. The 3D scene is optimised for mobile GPUs; walking works with an on-screen joystick. Heavy scenes load simplified geometry to stay smooth.
Does it support VR headsets?
Yes. The 3D scene opens in WebXR-compatible VR headsets right from the browser — you can walk the future garden and even move objects with controllers.
More about the planner
Free garden layout planner for beds, paths and plants
Map the whole growing area before you plant: draw the boundary in real feet or metres, place raised beds and a greenhouse, leave usable paths, and compare the layout in 2D and 3D. Gardmi works in the browser without a download, account or credit card.
-
1
Draw beds to scale
Outline rectangular or custom-shaped raised beds with their real dimensions instead of estimating space from a picture.
-
2
Keep paths and access clear
Add paths, a greenhouse, water points, compost and storage, then measure the routes used by a wheelbarrow or garden cart.
-
3
Place plants and check shade
Add plants at their expected mature size and use 3D to compare tall crops, trees and structures around the beds.
-
4
Print the garden layout
Export the finished vegetable-garden layout as a PNG or a to-scale PDF to take outside when marking the beds.
Planning boundary: Gardmi draws the physical layout. It does not generate local sowing dates, crop rotation, companion-planting rules or automatic crop-spacing advice; verify those with a trusted guide for your climate and varieties.
