Parliament will get a play space on the lawn out the front of the Beehive.
Speaker Trevor Mallard announced the plans, aiming to increase engagement with Parliament, on Tuesday morning.
"Parliament is a place for everyone, and this space will help demystify Parliament and make families and children feel more welcome," the Speaker said in a statement.
The design hasn't been formalised but will use natural materials and reflect the history of the land.
Construction is due to begin in spring.
The Speaker is also considering opening Parliament's cafe, Copperfields, to the public on non-sitting days.
"This is in order to encourage its further use, get people into the building, and provide a more consistent clientele for Icon Venues, the company behind the catering and cafe, and more regular and predictable hours for their staff."
