An extension is a big decision for your home and your finances. You will have to think carefully about the logistics of the building process, as well as how you will use the room and what you want to get out of it. If you are going to commit to having a new extension, then you really need to make sure that it is going to be right for you.
The aesthetics are very important, as this will shape the room and the way you use it. Make sure there is plenty of natural light – if your extension is a conservatory, this won’t be a problem, but otherwise, corners of the room could become dark. You can use rooflights to make this better if required.
You should also think carefully about the insulation. Make sure the new part of your home will use good insulation and will be cost effective for you to have.
