Floor plans for Lennar's "NextGen" homes include two separate external doors -- one is an entry to the main section of the house, and a second door allows access to a one-bedroom, one-bath suite.
"We've seen a lot of interest for them. It's been very successful on the West Coast," said Jack Lazinsk, the vice president of sales and marketing at Lennar in Orlando.
The "Independence" floor plan includes four bedrooms, 2.5 bathrooms, a three-car garage plus a secondary living suite -- the "home-within-a-home." The suite includes an additional bedroom, bathroom, a small living area and kitchen with full fridge, stackable washer and dryer, dishwasher and microwave.
A door allows access -- or privacy -- between the suite and the main section of the home.
