Permission for Glass enclosure for house.
Can anyone tell me the procedure to apply for permission to have a glass enclosure added on to the front of the house? Perhaps there is a better description for this but the house is in Puerto Marina in Gran Alacant and I have noticed quite a few houses here have this glass enclosure which extends from the front door to the balustrades. Has Anyone done this and if so can you tell me where to apply for permission and if there is an email address please, thank you.
