We are currently considering extending downstairs, to put a family-type room onto the kitchen diner, with bi-fold doors out onto patio. Budget considerations, and other work which needs doing, mean we may need to downgrade from proper extension to conservatory. However our architect and his wife, who assists him and advises on design, have advised that conservatories, especially south-facing, which is what ours will be, will be very hot in summer, cold in winter, and we would end up not using it. They said they are taking loads down.
So what is your experience? Do you use your conservatory? Is it too hot in summer if south facing? Interested in all opinions, as we only have their word to go on.
