Is there any way you can get rid of the clutter that's in the room or do you need to keep all of that stuff?

You could install racking for both sides of the room, toys & clothes that aren't being used can go into large plastic containers with lids. The two bikes could be hung from the wall or ceiling. And yes, anything that doesn't need to be there, move it on. There are so many hooks and storage options available that it would be very easy to sort this out and by getting a lot of it off the floor.

At the moment i am building a fence and after that i am moving on a shed which is going up against it, so most of the stuff in the photos will be going in there so then i will post more photos of progress

good idea to post progress photo's - if you can spend some money - storage cupboards like the white tall cupboard can help and the latest thing is to suspend your bikes from the ceiling (lifting them off the floor). Also see if you can sell some of the furniture, that could help you finance some of your storage solutions.
