Sand and water play table looks good
My first reaction was to wait on the play house till she gets bigger and get a bigger one. I found mine play with them when older. that might just be my kids though!
We had/ have one of those tent and tunnel type things that was used more at toddler age for crawling in and out and in etc good for developing those gross motor skills.
I d say things like a outdoor ride on for getting on and off and putting things in and out are good. Also just things like a bucket and spade and a patch of soil always goes down well especially when you don't necessarily want her to be covered fully in mud that day.
A paint brush and a tub of water is always good fun
