It's a Minihus!
Continuing my daydreams and fantasies of simple summer dwellings, (and by extension, how to incorporate that sensibility into life and living the rest of the year), here is a modular design by Lars Frank Nielsen of One N Design in Denmark for Add A Room.
One 15 sq. meter shed-roofed box with the option to add on a sort of 'connector' room, which in one delightful photo shows its use as a summer kitchen. . . (sigh). They call it "Compact Smart Living simply" and they are as cute as can be. See more here: Add-A-Room. Website is only in Danish or Swedish. Good luck. – GF
