South Facing Conservatory
A south-facing conservatory gets the sun all year round, making the most of winter sun but because it will gain more heat and retain it longer without adequate ventilation it can become uncomfortable.
In summer a south-facing conservatory will need opening windows and roof vents. Double opening or French doors are sensible additions, or you might find it preferable to have a sliding or concertina door that will allow more air to flow into the conservatory.
You will almost certainly need roof blinds and/or solar reflecting glass and you may also need to consider air-conditioning.
However, you will be able to enjoy your evenings in a south-facing conservatory when the sun is lower on the horizon or gone down. Some of the daytime heat will be retained making it a perfect place to relax with an evening drink!
