Building a Garden Office / Shed
Here are details of our garden office built as a D.I.Y project. This has nothing to do with technology, but I didn’t have anywhere else to post this blog article.
This shed uses a custom design put together to make the best use of the space available.
The structure is made up of the main area 8ft x 16ft. A dedicated shed area for garden tools that is 2ft x 2ft. Also, a veranda area providing weather protection for the entrances.
It has full electrics using an existing armoured cable run from the house. This is connected to a 3way consumer unit providing indoor/outdoor lights and sockets.
Treated softwood is used for the external wall covering as it is considerably less expensive than hardwood. Both wood types will go grey if not treated yearly, so the additional expense wasn’t justified.
The total cost was approximately £4000, which included tools and materials. Most of the materials were purchased when stores had discount days or unused purchases on eBay.
