To be honest this shed is a storage solution, not a workshop. It’s great for keeping your tools and equipment clean and dry, and keeping pests and the weather out.

“It looks nicer than some of the houses in your street!”

This great looking shed suits any yard. In fact it looks nicer than some of the houses in your street!

The polyethylene (popular form of plastic) is UV and fade resistant so the shed looks good year after year, with no need for sanding, and painting. And when you have to clean it, just grab the hose or pressure washer.

The construction incorporates both plastic and steel. The steel reinforces the roof and doors which help keep the shed sturdy and solid. Although people typically think of plastic sheds as light and flimsy, this one is a heavyweight and hits the scale at 751lbs (340kg).

Along with steel bracing the doors have an internal lockable system, and adding additional security measures wouldn’t be hard if you were so inclined.

Low maintenance


The door opening is huge at 4’8” by 6’4”. It’s so big, IT ALLOWS EASY ACCESS FOR LAWNMOWERS, WHEELBARROWS, LARGER GARDEN EQUIPMENT and our taller friends who are often inconvenienced by low shed doors. The inner roof is quite high also with a inside height of 7’8” with a minimum height (in the corners) of 5’8”.

However the floor is soft and easily dents. I’m not sure how it would go with constant abuse from a lawnmower, or if you worked in there. To be honest this shed IS A STORAGE SOLUTION, NOT A WORKSHOP. It’s great for keeping YOUR TOOLS AND EQUIPMENT DRY, and keeping pests and the weather out.

The shed is kept light through two windows and six skylights on the roof. However the natural light isn’t great, and requires bolstering if you did want to spend any decent time in there.

The shed can get quite hot in summer if it is in the direct sun, as the air flow panels are small. (On the bright side this will slow the rust process down on your mower.) However, the windows do open up to allow some air flow. But as we said, it’s not really a work shed.


To help store more items, included with the shed are two 90” shelves, two peg strips with hooks for tools and four corner shelves. These corner shelves help stiffen the shed. There is PLENTY OF SPACE FOR MORE SHELVING including more corner shelves. You can even extend the shed if you need to.


It comes in 4 boxes of which the instructions are in the first box.

The instruction manual (in the first box) is a little tough to understand. The only help we could find is that you can download the latest manuals from the lifetime website. Just put in the number 6446.

As for the constructing, it depends whether you are a glass half full or half empty type of person. There are well over 200 screws to put in with this project along with approximately 7-10 hours. It can be a fun day if you browse the construction manual before you get started.

The 10 Year Warranty:

The shed also comes with a limited 10 year warranty. The warranty entitles you to a replacement part if any defects impair your use of the shed, although misusing, abusing or negligence on the owners behalf, as well as incorrect installation voids the warranty. Which is pretty standard when it comes to sheds. (Please see the instruction manual for information on the warranty)

Having heard of others circumstances dealing with the company, the customer service at Lifetime is quite good, and queries are answered promptly.

Tips for your shed:

The shed is strong, but as only as strong as the base. You really need A STRONG LEVEL BASE TO SUPPORT THIS SHED. If not concrete, then a solid wood base with sheet (such as ply) over the top. And if the base isn’t level, the doors won’t shut properly and the panels won’t sit in straight. A level base is very important for this shed.

If left in the heat, the plastic will expand easily. If you are building the shed, leave the pieces in the shade until you need them. ONCE TOGETHER, THE SHED WILL BE STRONG AND STURDY.

Inserting the side panels into the floor can be tough, using a lubricant like WD40 makes the job easier.

If you are running electricity, drill a hole through the floor and come up through your slab or timber flooring. Some conduit and it will look neat and tidy.

Our Verdict:

A great looking large garden shed, that keeps your equipment dry, and allows easy access. A great buy to store your garden equipment, and tools.
