Quite possibly the most over spec'ed shed ever built! It has cavity walls, double-glazing and a big loft for storing stuff. It has two rooms - two-thirds for me and the boys and the other third for wife's gardening stuff. It is nice and toasty in the winter.
My brother and I built this shed once son number 2 came along and there was no more room in the house. Currently it is a workshop and drinks store, but reckon I'll lose it in a couple of years for the boys to use as a hobby room.
