iFloorplan is a service for creating and hosting interactive floor plan tours. To create a iFloorplan tour you need to have a floor plan already created. iFloorplan doesn't help with the issue of creating your floor plan, it just creates and hosts tours that display media (still photos, video and 360s) in a tour format that uses a floor plan as a reference on the screen showing the viewer where they are in the home. The viewer can control which room they want to view or press play and sit back a let the tour automatically take them through each room. The result, is a very compelling way to view a tour. I know from direct experience, many sophisticated home buyers want to understand the floor plan. It helps visualize and get a better feel for the space.
iFloorplan supports iPhone and iPads for viewing iFloorplans although to create floor plans you need a machine that has Flash on it.
The crux of doing floor plan based tours is producing the great looking floor plan as in the image above. I did a post in Nov of 2009 on ways of creating floor plans. Out sourcing the drawing is very cost effective and there are many people that do this. Here is a list of Rob's suggestions:
Be sure to check if the home seller has a set of blue prints for the home. About 30% to 40% of our listing customers have had a set of blue prints tucked away in the attic or some place that I can just scan and do a quick floor plan "tracing" from a photoshop layer above the scanned floor plan.
