My first hexagonal garden shed was constructed in 1998. the main timber construction was still fairly sound and I set off to move it to a new site further down the garden. Upon dismantling it I realised the error of building it on a wooden base. The base was made from toughened waterproof plywood, used in concrete casting but over ten years in contact with the earth it had completely rotted down. As the first shed was slightly too small I decided to build a new one. All was not lost with the original shed. A friend of mine was glad to take it away and rebuild it as a small garden room.
Step 1: Hexagonal Shed site clearance and base
I decided that the new shed would be built to last and as my new hobby is stained glass, I would incorporate some nice windows The base was to be concrete so I needed to formulate the size and construction method. I was a bit low on carcassing timber for the main build so I used six of the pieces of 2x4 wrapped in clingfilm and reclaimed them like new once the base was cast and left to harden. I then laid down some heavy duty damp proof membrane, and build the floor frame. All the timber was painted with anti fungal/pest you name it preservative. Dropped in some 50mm insulation board between the timber then topped this off with 30mm waterproof plywood.
Step 2: Diagrams and cutting plans
I used some software to figure out the best way to cut the 8’ x 4’ sheets of ply with minimum wastage.
This was useful for all the ply cutting. I used Visio and Sketchup
