A design studio for land

Turn your survey
into a site plan.

Type the bearings or trace the PDF. Siteplan draws your boundary to scale, lays it on the real terrain and gives you the tools to zone the land and place every building where the ground suits it.

How it works

Survey in.
Site plan out.

Three steps, all in the browser. No CAD licence, no GIS training, nothing to install.

01 · SURVEY

Bring your boundary

Type the bearings and distances off your plan, trace a PDF or photo and set its scale from one known leg, or paste beacon coordinates. KML and GeoJSON work too.

02 · TERRAIN

Read the land

Real elevation loads under your boundary: hillshade, slope bands, contours and a map of where the ground is high and gentle, where water collects and what's too steep.

profile A–B: steepest 11%
03 · DESIGN

Zone it and build it

Draw zones and watch areas update in m², hectares, acres and plots. Drop buildings at their real size. Subdivide into plots. Look at it in 3D. Export.

Villas 1.91 ha · 29% of site

Every decision, measured

Put the house where
the ground agrees.

Select anything and the inspector tells you what the land is doing underneath it: how high it sits, how much the ground falls across it, how close it is to the boundary.

The tools

A drawing board
that knows the terrain.

Everything a landowner, architect or surveyor needs to go from a survey plan to a site plan they can defend.

Bearings & distances

Type the legs off your plan. Siteplan closes the traverse, reports the misclosure and spreads it across the legs.

Survey

Trace any plan

Drop in a PDF or a phone photo, rotate it upright, click the beacons and set the scale from one leg you know.

Survey

Terrain layers

Hillshade, slope bands and contours at 1, 2, 5 or 10 m. Hover anywhere for height and slope.

Terrain

Elevation profiles

Draw a line across the site and see the section: rise, fall and the steepest stretch.

Terrain

Where to build

One overlay shows high, gentle ground, hollows where water gathers, and slopes to leave green.

Terrain

Zoning, counted live

Sixteen land uses, from housing to lawns and paving. Every zone shows its area in m², hectares, acres and plots, and its share of the site.

Design

Buildings to scale

Houses, villas, apartments, pools, courts and barns at real sizes. See the fall across each footprint and its setback.

Design

Plots, 3D & export

Subdivide a zone into plots with roads, orbit the plan in 3D over satellite imagery, export drawings and CAD files.

Design
Who it's for

Anyone holding
a survey plan.

For anyone with a survey plan and a piece of land, anywhere. The survey is the record everyone has; a site plan is the thing almost nobody can make for themselves.

Landowners

Family land, farms, a plot bought from abroad: see what it is and what it can hold.

Architects & planners

Start the concept on real terrain in minutes, not after the topo survey arrives.

Surveyors

Hand clients a site plan alongside the survey. Show them the boundary on the ground.

Developers

Test layouts, plot yields and road lengths before you commit.

Students & teachers

Learn traverses, contours and site planning on real land.

Questions

Plain
answers.

Is this a legal survey?

No. Siteplan works from the survey you already have and helps you design with it. Boundaries, title and setting-out on the ground still need a licensed surveyor.

What do I need to start?

Your survey plan. If it lists bearings and distances, type them in. If not, upload the PDF or a clear photo and trace it. Coordinates for one beacon (printed on most plans) let Siteplan place the site on real terrain.

How accurate is the terrain?

It comes from open global elevation data, which in our tests matched on-site GPS heights to within about 4 metres. That's enough to see ridges, hollows and slopes and to plan sensibly. For engineering design, use a detailed topographic survey.

Where is my work saved?

In your browser, as you work. Export a project file to keep a copy or move it to another computer. Cloud projects come with Pro.

Does it work on a phone?

You can view and explore plans on a phone. Designing is best on a laptop or desktop with a mouse or trackpad.

Which coordinate systems does it support?

Every UTM zone, north and south, plus latitude and longitude, so it works for sites anywhere in the world. National grids are on the way.
