I will take some of mine later, I have kitchen cabinets to the rear wall with a bench on top, the bench is supported by battens.
I have a roller cab which houses all of my tools, one drawer for sockets, one for screw drivers, one for spanners, the top section opens up and houses all of the task specific tools.
I also have a large Bisley tambour which houses all of my chemicals and power tools, I am going to replace the kitchen cabinets with two more tambours as they are so much easier to use without having to open the doors into work space. Very cheap second hand.
All of my bike bar two are on pedal wall mounts, it takes up the least space compared to hanging by wheels.
Be careful what you horde, you really don’t need all those left hand 3 speed shifters….
