I can't speak to that company, but there was a garden shed in my current yard when I moved in. Love it! I wish it was in a different spot, and still may get around to moving it, but I will always have one now.

The first things to consider are local regulations relative your needs. (Remember your estimate of needs, will be significantly less than future requirements) It would have been nice to have built a 20 X 25' foot shed to store the boat, But because of the local regulation, the one I built was 10'X12' with no permit. It is barn roofed with two 4' lofts in each end. I have threaten to put electricity in the shed but do all of my yard work in the daylight so never have justified the effort.

While it will not hold the boat which fits into the garage, I have all of my yard equipment stored there: lawn tractor, lawn trailer, spreader, chipper shredder, and much small equipment. I have a couple of shelf units for storing small items that would be inconvenient to put in the loft.

With all of this stuff organized in its place in the shed, I have room to work 360 degrees around the tractor, and have a nice size 20" X 40" work bench in the front corner. The wall above the workbench has a pegboard for all of the tools I need in the shed.

Garden sheds are awesome for outdoor/seasonal tools and toys. I just bought a house and have been looking at a shed for my own property. The zoning laws in many places here have a maximum square footage that you can build/erect without needing a permit.....In places where was looking at houses, you're allowed 100 sq ft without a permit, so check your local regulations. I don't know that company, but agree with the concept

We had a garden shed at our last house and it was wonderful to get the equipment out of the garage. We had to add a lot of storage to the walls, like hooks and shelves. But, some things ended up in the middle making the walls harder to reach.

In your link, I like the shallow, long ones, they are less than a meter deep, with double doors. This means you can use the walls to hang everything up, but there will be very little in the way of reaching them.

I suggest adding a small deck at the doors, so that you have a dry spot to stand or let a tool dry before storing.

BTW, my 10x12’ shed (about 2m x 4m) had a small window which we liked, and I added a small wire planter basket to it. At first I planted flowers, but of course they dried out so quickly. I replaced them with artificial flowers that I switched out a couple times of year with the seasons, and it looked nice, and far enough away that they didn’t loook too fake. I just had to remember to remove the Christmas flowers by spring!

You can buy free standing ones of various sizes from hardware stores. I have one for my garden tool and lawn mower.
