Switch between 3D and a flat 2D plan, zoom in, show only the cottages. Green means free, orange means reserved. Some plots hold two homes, so they split into A and B, each with its own size and plot.
One map instead of a price list PDF. Buyers get it in seconds.
This is so much better than a price list PDF. I build PlotToBuild, a sales tool for real estate firms selling plots in Nigeria, and the free / reserved / sold status is exactly what buyers ask about first. Splitting plots into A and B is a smart touch.
