Can anyone recommend web sites that instruct one in the building of a
greenhouse? Googling doesn't turn up anything interesting.

Do you want to build it from wood, alluminium or upvc?

Wood with about one metre of brick wall at the base.

start with what
you want to glaze it with as this nearly allways comes in standard sizes

I didn't know that. I thought glass merchants cut it to any size.


Horticultural glass is usually of 3mm thickness as apposed to 4mm which
is the lightest weight window glass

There are 3 standard sizes of Horticultural glass, Dutch lights which are
large and hard to handle and I would avoid

2' x 2' and 2' x 18" (although I think that has become 610x610 & 610 x
457)

Other possible sizes are 610x508, 610x533, 610x559

But the basic spacing is 610mm any more and it starts to be unsafe for
that thickness of glass, whatever you decide a conversation with your
glass supplier before you start will save you lots of time and money.

NB its much harder to glaze wooden home made greenhouses as most of
the clip systems are designed for the alluminium houses (try and avoid
putty at all costs, and I personally would also avoid painted finishes)
