A contact centre is a building and it can look very different depending which one you use. Sometimes, they look like a house, and other times they look like an office building. Contact centres can also be in schools. Because they are all very different it might be best to find out the name of the centre you will be using and then look on google to see what pictures you can find.
A contact room is usually a good-sized space with pictures on the walls. There is almost always a selection of toys and games. Often there will also be other things like art and craft for example. There is often a table and chairs, sometimes there might also be sofas or bean bags too.
If you are having supported contact, you might have an even bigger room where you will also notice other families sharing the space. For supervised contact you will have this space to yourself.
