A Sunroom is an excellent way to add an extra room to your home. Whereas a conservatory is essentially an addition to your home a sunroom is an extension.
Sunrooms are built with tiled or slated roofs so are better insulated than conservatories. Whereas Conservatories tend to be warmer in summer and cooler in winter, sunrooms are generally the opposite.
Planning permission only required for Sunrooms over 17 sq meters but it never does any harm to acquire Building Control approval.
