Who knows why, when we think of space-saving ideas for home, we only imagine economic solutions for tight spaces, Ikea style. Nothing more wrong. The multi-function business, above all, is widely requested in high-level furnishings and designers compete to invent the most useful and pleasant solutions at the same time. Decomposable sofas and tables that become something else, readjustment of pillars and basements to create bookcases and pantries, very useful inserts for wardrobes to keep everything under control and in order. We have collected a series of all this for you to help with your design ideas, and perhaps make you discover that there are already solutions to problems that you would like to see solved in your apartment.
