I’m guessing that reference to dads workout/bike area means he’s either a triathlete or cyclist. We’ve got lots of gear! May I suggest some storage for his area? I like those cube storage shelves (ikea, Target, Walmart) all sell them. They are great for storing hand weights, foam rollers, canvas drawers for things like gloves, arm warmers, etc. then make sure you’ve got an outlet nearby. The top of the shelf can be a nice surface for dad’s tablet or phone so he can either watch movies, listen to music on headphones, or just follow along with is training plan while riding. I also like a yoga mat for post ride stretching, etc. (I also place my bike & trainer on top of an old yoga mat. Helps protect the floors and keeps the ride steady.)

Not sure if that helps at all, but that’s where my experience is, versus playroom ideas :) Happy planning!

What about a wide window seat or daybed type seating with lots of pillows vs a sofa? Then you could do other chairs (kid size?) or a small table with chairs (there are also great tables that have a reel of drawing paper - I think IKEA or Container Store? Or make yourself) in the center. Kitchen set on a wall (table can be used for tea time) and storage units on the sides (like a kitchen). Eventually table could be converted to train table.

PotteryBarnKids has a Play Table to which you can add the drawing paper roll. That would be very multi-purpose, esp for a toddler. And then the windowseat/daybed could have drawers underneath for storage (and be cozy to curl up to read books, take a nap, etc). Maybe even a painted tree in one corner with bookshelves (would go with the rug you picked)

Below are a few fun kids play room ideas (also some bedroom designs) from designs we have done for other clients. Take note of the shelves, storage, rugs, artwork, and lighting.
