How can I design a versatile and functional layout for my enclosed porch that includes built-in storage and seating for my growing family?

Looking for some advice! Our enclosed porch connected to the kitchen is a bit of a mess – it’s currently used for storage, as a mud room, play area, and extra seating all in one. Planning on starting from scratch and installing built-in storage and seating, but not sure where to place it. Thinking of keeping the seating and storage on the window side only, without anything against the kitchen wall.

Any suggestions on how to lay it out? We have two young kids with tons of stuff, but they won’t stay little forever, so we need a design that can grow with us.

I’ve attached some examples from Pinterest of built-ins that I like, with a mix of drawers, open storage, and lift top storage for different types of items.
