It is necessary to leave sufficient working room around your greenhouse when you're putting it up
and also to allow for the possible need to replace a piece of glass in the future. If possible try and
leave a space of 2ft/610mm around the greenhouse.
Locate the greenhouse where there is maximum amount of sunlight
and avoid if poss
i
ble any shade
from trees, fences or other buildings. Over-hanging branches can be a particular nuisance and should
be avoided.
Choose a site where the greenhouse is relatively easy to get to and convenient to bring water to and
possibly a supply of electricity.
Finally, and most importantly, choose a site where your Alton Greenhouse will look right so that it
will complement your garden.
