Don't discover the awkward corner after the reservation.
Frontage, elongation and usable ratio show up before you commit deposit.
“The MIR made it obvious the garage wouldn't fit the way the listing photo suggested.”

See if the shape can actually take the house.
Propibay measures compactness, rectangularity and a setback-aware buildable envelope — so “nice looking plot” becomes a number you can defend.

Book a demoWho it's for
Geometry is a negotiation, not a trivia fact
Buyers, developers and appraisers all inherit the outline — make it explicit.
Price the envelope, not just the hectares.
Setback-aware buildable area and MIR efficiency separate soft options from hard constraints.
“We killed two sites in a day because buildable_empty would have been true.”
Document shape risk with metrics, not adjectives.
Compactness and rectangularity land in the file as reproducible numbers.
“Score 78 with MIR 17×22 — the client stopped arguing ‘irregular’.”

Eyeballing vs. measured buildability
Toggle between shape quality and the setback envelope — same 780 m² parcel, two lenses.
Compactness and rectangularity explain why two equal areas don't build the same.
Without Propibay
- Listing area≈ 780 m²
- Shape“looks fine”
- Buildable???
One number on the flyer — zero setback math.
With Propibay
- Compactness0.78
- Rectangularity0.97
- Composite0.88
Verdict: Compact · good buildability
