Size is a matter of the mind, a sense of space is distortable, based on the feeling, not on the actual enclosed area. These houses are the same size on the ground, 12′ x 28′ but the roof height on one side only is higher yet it nearly doubles the usable square footage of the house, based on the feel, functionality, and layout, not the actual addition of more floor space. 2nd floors and lofts are cheaper to build as you share a common roof and walls. I like this roof line better and can fit a full 3 bedroom with a private master suite, a living area, full kitchen, and bath with porches and fun built into it too. Amazing what can be done with a 350 sf taxable footprint.
