As longtime cabin connoisseurs, we've come across many unique designs and impressive structures over the years, but Cabin ANNA by Dutch designer Caspar Schols might just take the cake (stroopwafel?). Originally built for Schol's mother on a tight budget of $23,600, the ANNA design has since been released in two prefab models sure to impress even the toughest critics.
Inspired by railway station trusses, the ANNA cabins not only boast intricate internal structures but are locomotive-like themselves. Each cabin is divided into three parts: two external shells that roll apart, with a movable greenhouse-like structure nested underneath. One portion of the cabin acts as an anchor and stays fixed, while the remaining unit and the glass structure move on rails, creating an adjustable system that adapts to varying weather conditions (or the whims of a visitor).
