In a very small room, with a high ceiling, I created clothes space by reusing old KALLAX units and an old IKEA kitchen rail (BYGEL).
This cost me only £15 for two new wardrobe rails. I only used basic tools of spirit level, electric drill (for wall holes etc.), battery powered screwdriver and a very small amount of glue I already had.
I had a limited budget as I had to refurbish a large flat for rental.
This is in a rental property and I knew the room was to be used for either an office or a bedroom for children.
The 2 units are separated by wardrobe hanging rails bought from a DIY store.
It was vital to ensure both the top and bottom units were attached strongly to the wall.
I then screwed and glued an IKEA old kitchen rail underneath the top unit to use as a hanging rail for clothes. This rail had to be strongly glued as the weight of clothes could tear screws from the KALLAX unit. I used Gorilla glue brand.
The unit created clothes space in a very small room and has been used by various tenants for over 4 years and has held both children and adult clothing.
