Unfortunately the council won't allow us to make it fully self-contained so a kitchen is out but we can have an ensuite which is great. Means the space can be used for whatever we want - office (our need right now) or an extra living room or an extra bedroom. That would be fab if we had another baby so I could spend the first few months out there doing the night wake-ups without disturbing the rest of the house. And if DP is still a shiftworker, he could use it to catch up on his sleep during the day without me having to pad around the house which just about sent me bonkers last time!
