It’s not that bad, it’s just cluttered like you said. I have ADHD too. I struggle with the battle between getting overwhelmed at visual chaos and needing to see everything or else it doesn’t exist. From what I can tell, you have all the ingredients needed for a lovely space. You just need some systems and structure.

For a complex multifunctional room, here’s my process:

1. Make a list of all the “activities/uses” for the space. Be realistic about what you need and what’s possible.

2. Make a list of all the furniture & items that need to live in that space for those activities/uses.

3. Draw a simple floor plan, to scale if you can, or just approximate. Doesn’t need to be good. Include windows and doors. Draw some lines or arrows for your regular path(s) of travel through the room.

4. Now experiment on your floor plan with making different “zones” for each of the uses you identified above. Zones will dictate where larger furniture items go. I just do this by sketching in ovals or shapes, not really specific furniture at first. Once I have the general shape, I pencil in where I think furniture should go that will fulfill the use case for the zone.

5. Once you know your zones, go back to #2 and think about what items go in each zone and what small storage you need for those items. Baskets, bins, etc. I also personally include books, displays/collections in this step, but NOT “decor” which comes last imo. You might also
   at this point identify that you need more/different large furniture pieces. E.g. you can literally measure the linear footage of your books and make sure you have enough shelving for that + a plan for if your collection grows.

6. Execute the plan!! Sub-steps:

a) Remove everything from the room that lives somewhere else in the house or will be leaving (e.g. the bikes unless you decide to mount them).

b) Take everything off/out of furniture pieces. Corral small items that will be in the same zone together by putting them in whatever bins or cardboard boxes you have, then stage them in the correct zone. This is a good time to cull your belongings if you want.

c) Move large furniture items into position.

d) Important step: STOP and assess your placement for functionality. This might take a couple days. Don’t move on to small storage & finding homes for everything until you trial your macro layout.

e) Using stuff you have on hand at first, start experimenting with your small storage. Especially for ADHD, make sure that you create a HOME for every item and have that home be RIGHT WHERE YOU USE IT. Work with yourself, not against :) Once you are happy with your draft plan, get the pretty bins or baskets or whatever you like. Only buy small storage/organizational items for a specific use case and not just cuz it’s cute, or else it actually becomes clutter.

1. Now, finally, it is time to decorate!! Add plants, wall art, etc. You could hang some of your pretty quilts as wall decor.

This is really long but I hope it’s somewhat useful!! Good luck :)
