Set up some kind of charging station for devices - we have a couple laptops, Kindles, headphones, a Dash robot, etc. Having a dedicated spot for all the devices with a good surge protector makes sure everything gets put away and plugged in. A roll-y type cart to hold arts and crafts supplies so you can bring it to where it's needed. A binding machine. I recommend one that uses the ProClick spine system because then the spines are reusable and can be cut down to make any size you want without special tools.

I'll suggest looking carefully for some of these newer compact Gallium nitride "GaN" chargers and paying attention to their wattages. It's very nice to super fast charge laptops, tablets and phones all from one little charger at once. Anker makes some good ones.

I much prefer having my laptop over a desktop for homeschooling, because it allows me to keep up with it all over the house and takes up less space on my desk. Creating things for them when they are young, for me at least, has involved both tech and some basic crafting. I also prefer to plan with my references open. Both require plenty of space without keyboard, mouse, etc in the way. I use my laminator all the time with the younger ones, as well as my paper cutter. (I already had one for my paper crafts.) I was annoyed having my primary workspace and printer in different spaces honestly. Things are arranged so it’s next to my desk now and I’m so much happier! Yes to a bookshelf. I like using our cube shelf because it fits larger books better as well as bins for manipulative storage since they are deeper than most shelves. We have a shelf in our “activity corner” that I store a lot at now, and the office shelf just has stuff for the age gap between my kids and my resources to plan from, but when my oldest was young all of our  maniupatives were stored in my workspace.

I do all my planning either in our school room or in our bedroom. I have a laptop instead of a desktop because I teach at a homschool co-op and use it during my lectures for presentations. In our schoolroom I have a shelves where I put the books we are using that current school year, my curriculum lesson plans and anything else the kids and I need. I have a rolling cart with school supplies on it for easy access. I haven't needed extra monitors or a drawing input device since I have been able to source any extra worksheets I have needed either through free resources or Teachers Pay Teachers. I prefer to do my planning in our school room because it allows me to grab whatever school books or workbooks I need to reference quickly and layout any resources I need for the upcoming week.

I kind of use our bedroom as an office. It has a desk and a file cabinet (that doubles as the nightstand) in there that I use for planning/organizing. I have the drawers of the file cabinet filled with folders by curriculum in one, by month for seasonal decorations in another, and one is kept treasures and things to look into. In the desk drawers, one is current planning and the other one is things like house cleaning/upkeep notes/stuff. There's no more room in there, but if there was, I'd go with bookshelves. 🙂 Right now all the curriculum books and binders are upstairs in the study room for easy access when we're doing lessons, but it'd be cool to be able to have some to reference down in our room, too. When the kids were littler and the study room was their dedicated homeschool room, it was really helpful to have all the shelves and nooks and crannies to store stuff. What's become the boardgame cabinet now had all their paints, puppets, and science/nature stuff. Where daughter's computer desk is currently used to be where the storytelling table was, and it was a low coffee table with baskets underneath that were fantastic for storing all the backdrops, peg dolls, scenery items. Where son's desk is now was the blackboard and shelves beneath with chalk, math stuff, crayons, sewing baskets, etc. We still have the closet in there full of supplies (felt, clay, paper, arts and craft and sewing/knitting stuff, science supplies, globes, puzzles, all the shadow theater stuff, things like the hole puncher/paper slicer, etc.), and it's still very full and needed for that storage. The bookshelf in there is super useful for keeping all the current books and binders we need, and the printer's there (daughter uses it just as much as I do; I'd feel bad if she didn't have easy access to it, too), along with the circle baskets of instruments and beanbags, and a reading area in one corner with some pillows and bed tent. Even though we generally do lessons at the table or couch, that room is still very used for games, research, reading and storage, and I'm so grateful we have it available for that. Planning-wise, I think just a laptop and some notebooks to write stuff down in has been what I've used most, but the biggest thing I can recommend to carry you through the years is enough places to put all that other stuff to prevent overwhelm/crowding in the space where you are doing your planning (it's hard to work and plan and organize without a clear space to do it) and a system that works for you for all the paper management. If you have those, you're good 😊 Edit: Everyone has different preferences, but my favorite system for binding curriculum/planners/literature guides, etc. is the happy planner discs. They're just really bright, colorful, clickety-clacky, and easy to maneuver pages around on and fold completely behind like spiral binding. If you have a laminator you can make really pretty covers for everything, too. It's a little silly and extra, but when something looks and feels cute and nice, it adds to the fun/motivation of the planning/prep.

Honestly, I feel that all I need is more storage. Storage for books, but also storage for games, flashcards, magnet sets, math manipulatives, and other oddly shaped items. There is absolutely *never* enough space. We can work at the kitchen table or outside or on the couch, and I can print and scan and work at my computer, but storage space is sadly elusive.

I have younger kids and the setup has changed slightly over time. I have a small desk area that’s right off the dining room/living room where we do school. I have a laptop that is on a raised stand with a separate keyboard and mouse for when I’m working there to make it more comfortable. I take the laptop to the school area to use each day with the kids but put it back here. Also have bookcases and cabinets nearby for curriculum, extra school supplies, etc. I use a rolling cart for the current curriculum and books we are using so I bring this close by for planning. I have a printer (Epson EcoTank I use to print most of our curriculum), laminator, paper cutter, extra binders, and large 3 hole punch. I haven’t found the need for additional monitors yet. What I thought I would need is different than what I actually need. I do like to be close to the dining table to lay out lots of curriculum when planning. I’ve found I don’t often go into a separate room to plan so my desk right off the main living areas has worked well for me to spend a few minutes here and there taking care of planning.

A really wide desk the width of your wingspan or larger. Maybe that's silly, but being able to have your laptop, a printout and multiple textbooks/teacher's guides and other books open at once is really nice.

- filing cabinet (for all the completed school work)  - filing box (to sit on shelf, for all of the upcoming worksheets/project instructions/papers, organized by unit or week)  - cube shelf with the fabric or basket cubes to store educational toys/manipulatives/models/project supplies  - a laminator  - a spiral binder  - a cricket machine or similar  - good, heavy duty printer (either laser with affordable cartridges or an eco with refillable cartridges)  - lots of bookshelves (especially if you're leaning Charlotte Mason or literature-based)  - rolling carts to store daily-used curriculum, manipulatives, and supplies  You could probably skip a second monitor.   I used two for work, but I've found no need for two at home.  

Actually- a laptop is better than a desk top any.  You can bring your laptop to your living area and cast to the TV when there's an educational video that would be helpful.

Bookshelves, cabinets, computer, printer, decent desk

Prep and plan area: shelves, drawers, filing cabinet, printer, laptop (desktop won’t be convenient and multiple monitors will be a waste), lots of baskets or cubes.  For me, it’s most useful if this area is attached to the schoolroom. I prefer a schoolroom with more shelves, more drawers, a chair for me, a desk and chair per child 3rd or higher, a cheap preschool table and chair set for littles, low footstool, beanbag chair, sleeping bag, folding rocking chair, exercise ball, balance board, mini trampoline with handle (if possible), and collapsible tunnel (if possible).  Wobble chair would be amazing, but pricey.  Cat tree and bed and/or dog bed. Different people need different tools.  I use a 3 hole punch, metal ruler, wooden yardstick, measuring tape, cutting mat and box cutter, (straight) paper cutter, hot glue gun, scissors, stapler, etc.  I don’t like fancy paper cutters, and I’ve never had a laminator.  My tools stay in my prep and plan area. Supplies consist of books, binders, paper varieties, writing and drawing supplies, glue, hot glue sticks, various tape, alligator clips, reusable grocery bags, clipboards, folders, kid scissors, wooden ruler, notebooks, staples, clothespins, safety pins, page protectors, lanyards and badge sleeves, a backpack per person, index cards and boxes, manipulatives, boards, pet toys and treats, water bottles, etc.  Supplies are kept in the schoolroom if they’ll be needed during that week, and the rest are stored in my prep and plan area.

I’d like to have a pin board of sorts so I can have a visual reminder of what I want to do/accomplish that school year. For example, I keep a folder for a variety of activities like a Kid's Wilderness Survival Skills day camp or a lampworking course. The other thing I would like to have is a Dreambox for storing everything. That last one might not happen but it inspires other storage ideas for me.

You could add a certified teacher

I am a certified teacher, who's definitely done with the public school system. I'm very curious as to why you thought this would be appropriate?
