This is a self build, I am not a professional and it is still standing. This out door space is 1 third shed for storing bikes etc and 2 thirds out door space. for my wife to do her crafts and crochet, i use it every evening for music (practicing bass and writing music)
Update - This has now turned into a She Shed as my wife has acquired this and moved in.
I started it in March 2015 and finally completed it 9 months later in December 2015.
I managed to get a great deal of the materials second hand or recycled.
I did all the work myself apart from the final fix and certification of the electrics.
The timber base was from A1 Lofts who did a great job of our loft conversion a couple of years ago. I emailed them and they emailed out to all their contractors to see if they had any spare timber. I met with Dan from A1 lofts in Harlow and filled up a van load of timber. http://www.a1pms.co.uk/
The 4 x 2s were from a recycling timber yard in Peckham.
The other items such as the windows and doors and the front maple cladding were second hand from ebay. I had to travel to collect items from all over Surrey, Kent, Hampshire and Buckinghamshire.
Other items I had to buy new, but shopped around on line.
