Oh Sam D if you could let me have a look at your plans, I am not much of a DIY person but you never know!
Hi Alex
Here is the basic parts list and building details. (Click on the website illustrations to enlarge)......

And here are the parts prices from Screwfix – Please note that single lengths of pipe are only available from Screwfix branches, as their internet/phone orders only come as a pack of 10x3 metre lengths.
6 metres of overflow 21.5mm pvc pipe £4.98 (2x3 metre lengths)
4 overflow 21.5mm 90% tees £2.59 (pack of 5)

If Screwfix is not convenient for you, B&Q and other sheds should be similarly priced.
As it’s constructed from plastic pipe, it’s not only cheap to buy the bits, it’s also very easy to cut with a hacksaw. My version is a bit larger than the size shown on the plan and I have mounted a large bulldog clip instead of the sheet-metal screws for holding the background paper. I also decided not to glue the joints, but use small fixing screws instead, and then only on the joints that remain in place when the frame is dismantled, finding it unnecessary to fix joints 1,2,3,and 4, (as numbered on the ‘top frame’ illustration).
In addition I used 4 additional lengths of pipe to make up 2 adjustable lighting diffusers, which simply lie across the frame and provide infinite variation to lighting. The diffuser material that I used is frost protecting garden/horticultural fleece. It’s cheap to buy and can be increasingly doubled up to achieve the desired effect. It can also be used to replace the background paper, allow you to illuminate it from behind if required. Horticulture fleece can be purchased by the metre from DIY stores and garden centres, or can buy an 8 metre roll of it from... guess who? Screwfix!

If you would like further help or clarification, then just let me know.
Have fun.
