I have half a small shed (shared with the garden tools, including the chipper and lawn mower), a small cupboard in the office (where I store beeswax, medications, gloves and ingredients for cosmetics), boxes of honey jars in the cupboard under the stairs (next to the front door for easy sales) and a pull out drawer under a sofa in the spare room (great for trays of full or empty jars, and big blocks of fondant).
There is NEVER enough space.
In fact I've decided that the extractor (luckily just a two-frame plastic one) is going to be moving into the loft this year, just to free up a bit more floor space in the shed. It's infuriating that an extractor it takes up so much room and there's not really anything you can store inside it to make better use of the space it takes up.
I think you just have to be creative with the space that you do have. I try to plan shelving in the shed to fit frames/boxes/nucs etc. most efficiently, and use hooks to hang bundles of frames, kit bags, from the ceiling and stack whatever I can on stands outside.
