First of all, where would you like your extension to go? The positioning of the conservatory needs to be taken into consideration at an early stage as it will determine at which points of the day it’s at its brightest and warmest. You might have a clear space in mind or you may be unsure what would work best. We can advise you.
If you have a lovely open view, you might want those sitting in the extension to be able to enjoy it. Or you may prefer a more secluded spot.
