Roost is an American real estate site that includes the option to view properties on a Google Map. The site includes all the usual real estate search options that allow you to search by price range, number of bedrooms and number of bathrooms.
When the results of a property search are listed the site includes an interactive 'mini' map. Clicking on any of the properties listed centres the map on that property and clicking on any of the house icons on the map moves the list to that property.
The site also includes an 'expand map' option to view a larger map. Clicking on the house markers on the larger map lists photographs of the property into the map sidebar and also adds buttons to view more details about the property and arrange a tour.
