I chose a 50×60 m rectangle because it allowed me to get exactly 3000 m², unlike a 54×54 m square (and drawing meters to a decimal point is pure nonsense). A one-story house with a cellar solves one requirement from the “storage” post, and the attic can work as an additional storage space for junk, as is usually the case. 10×8 m would be plenty of space for one person, which is what this whole mental exercise is about. The toolshed, workshop, and garage form one big unit. And the storage barn is as close to the house as it is to the toolshed and the workshop.
