I don't have a playroom.
Instead I use all of my downstairs space really wisely to work as a childmindig setting and my home.
Clever storage, not too many toys (I rotate half termly with stuff stored in the loft), lots of closed storage so you can't see toys, and my house looks no different to any family home really.
I have low down coat hooks for the children by the front door, but not brightly coloured kids ones, evaluation the same nice stylish ones that are higher up for the adults.
Book shelves in the sitting room are all full of children's books rather than adult books.
I have a lovely old printing press drawer unit with load of little drawers in the sitting room, all full of loose parts.
One kitchen cupboard full of art supplies (accessible to the children) low drawers and cupboard with their cutlery and crockery, three antilop high chairs that stack up, and kalax shelving with lots of option white boxes.
Conservatory has built in window seats all around that lift up for storage, so all bulky t go in there.
Parents have always been impressed with my house and how nice it looks, and how the children are obviously thought about but it doesn't resemble a nursery.
