Topbird, thank you very much. That clarifies a lot of things.
I will look to get a 10'x12' or 10'x14' depending on price. Plain aluminium and wont bother with the paint. Automatic vents and side louvres. Toughened glass.
In terms of electricity; my outhouse will be about 10' away from greenhouse and it does have a fusebox in so I will extend a line from that.
Outside tap is nearby so that's sorted.
Inside I intend to have raised beds on both sides in order to plant. The reason for this is that the soil in my garden is quite heavy clay.
I am also thinking of preparing a nice flat concrete base because the garden is uneven.
I assume the function of the guttering is simply to gather the rainwater (as opposed to offering protection? If that is the case then I am not bothered about guttering.
