At the very least they could transform the black shed of doom and turn it into a playhouse for Olive. Paint it white then paint a mural on it of some flowers, bees, birds etc.
Put some planters around it so she can grow some flowers and vegetables. Stick a trellis on one side to grow some flowers up it.
The list is endless and it would look a hell of a lot prettier than it does now! It currently looks like a construction site welfare unit.
Inside it can be done out pretty cheaply, and she can have a proper space to play instead of being stuck in the kitchen corner.
Olive just loves animals, why not get her a rabbit or a couple of Guinea pigs?
Now I’m no interior design exspect but it’s not hard to come up with something a 2 year old would absolutely love!
