I'm a slight hoarder, but my rule is absolutely not it the living rooms. My garage, hut, workshop and electronics working areas are jammed with tools, equipment, test gear and parts which might be needed 'some day'. I have a stack of internet routers, three laser printers, around a dozen of the more expensive watches I have bought since I started work, 5x laptops, 4x desktops - all working, in what I call my 'office'/ little bedroom. It has two filing cabinets, which store all the manuals for various equipment, all the utility bills, house deeds, car documents and etc..
Utility/pantry has to do double duty as a utility room and wine an beer brewing room. I try to limit the small items to just one wall cupboard in the utility, with the big 25L fermentation vessels stored in the 12 x 16 garden hut when not actually in use. Tractor/mower lives under a lean-to roof I built onto back of summer house, which is where I keep odd bits of plumbing pipes, larger lengths of timber, planks, sand and gravel, long single ladder, short single ladder, very long double extension ladder.
The hut stores strimmer, chain saw, mobility scooter (which might come in one day), dozens of spades shovels, axes, sledge hammers, oil paints, decorating tools and four pairs of steps of various sizes, Workmate and Christmas tree. Top cupboards of full width (massive) built-in wardrobe, stores Christmas trimmings, suitcases, spare toaster, electric kettle, two spare coffee making machines.
Airing cupboard has a spare 3-port actuator (ready to fit, should present one fail), a full set of old controls for heating system, just in case my all singing system should fail, plus a box of candles in case of power cut, bought 40 years ago. Under-stairs cupboard has a Kirby Heritage, with full tool kit and hardly used at all, it was bought and it turned out to be just too heavy for regular use; a normal lighter upright, a wet and dry battery vac, then a Henry in the garage.
Is that hoarding, or just being prepared?
