The Challenge
What was already failing
Listings were photographs in a grid. Buyers could not tell which villa sat on which slope, and requesting a viewing meant leaving the map.
The Solution
Find the place, keep the inquiry inside the listing, and hand the agent a time that is already real.

Search at the edge
Map tiles and listing cards resolve together. Panning does not blank the page.

The agent’s calendar sits on the listing. The buyer does not start a second conversation.

Key Capabilities
What the system is trusted to do
01
Map and listing, together
Geospatial search and the villa card share one request. The page does not reload to move.
02
A sold house stays sold
Price and availability are checked before a viewing can be promised.
03
Agent on the listing
Scheduling stays on the property. The buyer is not sent to a contact form to finish.
