Hello BW,
For a Garden shed, that fits in to the space as shown in below image, appreaciate any inputs on this subject. The requirements are as below
1. Storage of garden tools
2. Storage of Manure, soil, Mulch (around 3 X 25L each)
3. Couple of other items / parts associated with gardening.
4. Can that be mobile (Installing Wheels underneath) for cleaning the fence or at times when required.
5. Are there are blindspots which I have not looked at.

Should an off the shelf Garden Shed, be suitable, kindly ping the link. If there are any inspirational custom made projects, kindly leave the link to the thread.
Thanks for your time.
Happy Gardening.
MM
