Rightmove released a study in 2013 that suggests that real estate buyers consider floor plans not just nice to have, but essential when looking at properties. One in five said they would ignore a property without a floor plan. They also rated floor plans more important than photos and the description of the property. On the flip side, when sellers consider hiring a real estate agent, Rightmove found that 42% wouldn't hire an agent that didn't offer a floor plan. Adding a floor plan to a real estate listing can increase click-throughs from buyers by 52%. You can also use a floor plan to communicate with contractors and vendors about an upcoming remodeling project.
The roofs will be capped whether or not we build a second level on the garages because I'm not a fan of flat roofs. We're looking at about 9m length of wall to be built for each garage which would give us about 9sqm of space which isn't terribly efficient. It's a lot of wall compared to the space created.
