I visited a guy one time who decorated his 5 room flat with the biggest possible plants one could fit in each room (with a few spots to keep them alive). The 14x4.5 meter living room was a 2 seat sofa, a small table with drawers, a tv attached to the wall, very thick wooden floor with big cracks all over and 5 enormous plants in pots the size of bath tubs. No amount of money could have improved it.
