Plan your land before you build or buy

Draw the plot, see slope and sun, find out what fits and what it costs — in minutes, without being an architect.

The more precise, the more we calculate for you. You can skip it.

Draw any plot

Sides with live dimensions, or load the official parcel (Spain).

See slope & sun

Public elevation data and the real sun path for your location.

Know what fits

Place houses, cabins, wells and setbacks, and read the numbers live.

How it works

  1. 01

    Draw

    Three questions, then a plot already on the canvas. Adjust each side by dragging or typing its length.

  2. 02

    Calculate

    Area, perimeter, coverage, slope by zone, orientation and sun hours update as you work.

  3. 03

    Export

    Download the plan as an image or PDF. No email asked.

Data you can check

Elevation from SRTM / national DEMs via Open-Elevation, sun position computed from NOAA algorithms (SunCalc), Spanish parcels from the Cadastre INSPIRE service. Every figure on the site carries its source and verification date.
