The 1st pic of the house with the dormers:

The ‘Tiny Living’ design consists of a large family room with vaulted ceilings and large dormers on either side of the room. The entryway is situated at the back of the trailer allowing for a spacious 7 foot sleeping loft at the front. Under the sleeping loft is the bathroom and the kitchen. This house is available in 12′, 16′, and 20′ lengths, all of which are comfortably yet easy to tow. https://www.tinyhomebuilders.com/tiny-houses/tiny-living

The second house. This is the one Dan designed for his mom that got the company started:

The ‘Tiny Retirement’ design is a single level home perfect for those who would prefer to not climbing a ladder to go to bed. It is unique in that its entryway is situated on the long side of the house, allowing for a bathroom to be located on one end of the house while still leaving room for a full size bed or pull-out couch on the other end. The bathroom includes a 36 inch standing shower and a toilet, with a small storage loft located overhead. The total length of the house is 20 feet making it large enough to live comfortably yet small enough to easily tow. https://www.tinyhomebuilders.com/tiny-houses/tiny-retirement
