Miter Box by Shelter Wise. (The Pearl that was at Caravan Hotel was also built by them on loan/rented to Caravan. It was since sold by the owners at ShelterWise). You can see the design similarities between The Pearl and Miter Box.
The McG Loft from Humble Homes was created to make tiny houses more accessible to those for whom climbing a ladder to the loft was not an option. This home contains a wide staircase to the sleeping loft, making it perfect for the ladder wary.
