What this shelf is for
Resin and double-wall HDPE sheds from a 10 cubic foot doorstep box up to a 6 by 11 foot walk-in, each with a floor and a lockable latch.
Nine sizes in resin and hdpe, from 10 to 437 cubic feet before the walk-ins start, 6 of them with a floor pan and 10 with a latch that takes a padlock. The tall ones stand things up; the low ones go under a window.
Sizes on this shelf are listed with the ground they need, which is the number that rules a box out. The ZZM range is organised that way throughout.
Questions
Questions about ZZM outdoor storage sheds
How long does a ZZM shed take you to put together?
The mid-size resin boxes come out at about two hours for one person with an electric screwdriver, which is the figure the assembly notes give. The walk-ins are a two-person job: the wall panels are six feet and awkward rather than heavy.
Will a ZZM shed take your lawn mower?
It depends on the door opening, not the cubic feet. Front-door sizes take a push mower with the handle folded; a lift-up lid will not. Measure your deck width, usually about 22 inches, and check it against the opening on the page.
Can you store fuel or a propane cylinder in a ZZM shed?
Treat it as no. Gasoline and diesel are ignitible liquids with their own national rules about approved containers and quantities, and propane has a separate limit again. Tools, furniture, bins and lawn chemicals in their original labelled containers are what a box like this is for: and the chemicals want to be away from the mower rather than beside it.
Do you need a permit for a ZZM walk-in shed?
That is a local number, not ours. Many jurisdictions set a floor area below which no permit is needed, and a six by eleven can be over it. Ask your local building department before the pad goes down.
