What Mi Parcelita is

Mi Parcelita is a web app for seeing what fits on a plot of land in Spain before you talk to an architect or buy it. Look the plot up by its cadastral reference (referencia catastral): its official outline is downloaded from the Spanish Cadastre and opens in 3D on the real aerial photo and terrain. Place houses, garages, pools, courts and trees, and see the coverage, floor-area ratio, setbacks and sunlight as you go.

  • Find a plot by cadastral reference: outline, official area, address and existing buildings, from the Catastro's INSPIRE service. GML files work too.
  • Design in 2D and 3D: one- or two-storey houses, villa, cabin, apartments, garages, carports, pergolas, pools, padel and tennis courts, paths, hedges and trees, with editable sizes, floors and roofs.
  • Coverage and floor-area ratio: built floor area, floor-area ratio, coverage % and impermeable surface, checked against the municipal limits you enter.
  • Setbacks: draws the distance to the boundaries and flags anything inside it in red.
  • Real sun: the sun path on any date, 3D shadows and a sun-hours map that accounts for your buildings, trees, neighbouring buildings and mountains. Handy for deciding where the pool or the garden goes.
  • AI assistant: describe what you want and it proposes a layout that respects your setbacks and limits.

How it works

  1. Type the plot's cadastral reference (14 or 20 characters) or try the sample plot in Cádiz.
  2. The plot opens in 3D on the aerial photo and terrain, with the neighbouring buildings.
  3. Add elements from the catalogue, then move, rotate and resize them on the map.
  4. Set the setback and your municipality's limits, and check coverage, floor-area ratio and sun hours.
  5. Save the project to a file or export images to share.

How it works, step by step

Who it's for

For anyone who owns or is looking at a plot and wants to know which house and pool fit, how they face and how much sun they get; and for architects, surveyors and agents who need a quick first layout on official data. It is an early study: your town hall's rules and the technical project have the final say.

Frequently asked questions

How do I view a plot by its cadastral reference?

Type it into the search field on the home page. Mi Parcelita downloads the plot's official outline, and optionally its buildings, from the Catastro and opens it in 3D.

Does it calculate floor-area ratio and coverage?

Yes. It adds up the floor area of what you place and what already exists, divides it by the plot area and compares it with the limits you set.

Where should the pool go to get the sun?

Turn on the sun-hours map: it shows the hours of direct sun on every part of the plot for the day you pick, with the shade of the house, trees, neighbours and terrain.

Mi Parcelita is a tool for early studies. It does not replace an architect's project, your municipality's planning rules or the official Cadastre and Land Registry records.
