No need to worry about gender stereotypes for a cubby house. Dress ups, kitchen bits and pieces, table and chairs, toy cash register, clock, dolls, action figures, old costume jewellery, hard hat, toy tools, pencil and note pad. No limit to what can go in there.

The same as a girls cubby house!

Isn’t a cubby house meant to be a miniature of our homes? So fill it with what you would find in normal homes

I would put in a couple of games he can enjoy with his friends!

a kitchen LOL – and some toy cars, colouring books, and actually, why don’t you ask your son?

A mini gym set or tool room with bench and play tools. You can get ones that sound real. Shelves etc

We had a tool bench and a tea set and kitchen for two different boys.

Work Bench, inspection tray with spoons and little rake so they can look for bugs.

i would do the whole tool bench and that. I’m sure that he would be happy having a little shelf for his toys. Put up stickers or posters of cars or his fav movie

These answers are so cool! I want to build one for myself

I would put the kitchen in it – creative play helps build character (doesn’t have to be pink!!) or maybe a full blackboard wall?

toaster/kettle/ microwave/tea set/cutlery/fake food
Some dress ups (got nuts at the op shop)
A beanbag with some books

you could put a toy tool kit in there for him

depends what age your son is but boys like to pretend to be both mum and dad. So you could put a kitchen in so he can cook and make you cups of tea. You could put in a work bench with hammer, bench saw etc. Black board wall to write and draw on. Telescope, reading corner, puppet corner. If he’s a bit older he might like it as a spy club.

I assume you have the cubby now, what did you decided as there were some good suggestions I read on here.
