I'd like a den / teenage hideaway for the bottom of the garden - for the children (and their friends) who are currently 10 and 12. It needs to be big enough for a sofa and couple of chairs, perhaps a fridge, TV etc.
I've been googling but can't find anything suitable. Playhouses tend to be small and twee and with younger children in mind, but I don't want just a large shed. Any suggestions gratefully received
