Florida Room to Office Space

I have a Florida room in my condo that has served no other purpose, but to hold boxes.  Yes, boxes - boxes from mail order items, boxes from things we buy that come in large boxes.  It fills up with boxes and every so often when I can't stand the sight of so many boxes, they get torn down and put away, and the cycle starts anew.  Then all the torn down boxes which lie flat now increase in number and then eventually get recycled.  I think I'm a closet pack rat or hoarder.  I just keep stuff until I can't stand the clutter or space it takes up and then purge everything.

Anyway, it's a goal of mine to transform this storage room into another office/craft space.  There are a few downsides to this room.

1. Tile floors
2. Two of the four walls consist of nothing but windows
3. We never leave the connecting door open so it's never heated or cooled.  If it does become a habitable, usable space that means an increase in the gas and electricity bill and then it doesn't help that it's 50% windows.

So currently residing in the room is:

• the top half of an old entertainment center (the bottom half remains in our current office as it still serves a purpose for storage and helps frame our drawings)
• a wire shelving rack which stores above mentioned torn down boxes, our snowboard equipment, and some miscellaneous boxes
• 2 bikes
• A random piece from our elliptical machine which we sold
• Snowboard bag
• Boxes that have not been torn down
• 2 sets of golf clubs

The plan and the vision:

I have neither.  Just an idea of what I want to happen.  

• First, we need to get rid of bikes and half the entertainment center.  I'm thinking doing a curb alert on the bikes on Craigslist (one is in good condition - a kids spiderman bike with training wheels, the other doesn't shift).  Even if we tried to sell them on Craigslist, I don't think it's worth the effort for the $30-$40 we would get for them.  
• I want to break down the entertainment center and just drop the pieces off at the dumpsters over in the apartments by where we live.
• Go through the boxes and take the ones we want to keep up to the attic and tear down the rest and RECYCLE them.  I keep thinking we'll need these boxes in the future for some vague reason.  I need to let that idea go and just get rid of the damn things.  If I need a box in the future, I can just buy it.  It's not worth the cycle of saving and throwing away.
• Get rid of unwanted/unneeded items
• Clean the floors - I think we have spiders or something because every time I walk in there, there are the shells of some bugs in the corner with the spider webs.  I'll have to look in to that.  Maybe the bugs will stay away once the room gets more foot traffic
• Buy furniture - I admit we are still Ikea people.  I'm cheap when it comes to furniture.  I have grand ideas to go shopping at antique stores, thrift stores for some great finds, but I'm too lazy and not that lucky.

What kind of furniture?

I really like the Expedit book shelf from Ikea I bought a year ago and use to hold shoes and mail and my purse.

It lies on its side and I have 3 green baskets that sit in the cubbies.  I think it would be a good storage option for the new office.  It's $70, but the baskets go for $10 a piece and for the office, I'd want to fill all the cubbies, so that's an additional $80.  My local Costco had a similar piece that came with the baskets for $100.  Perhaps that would be a better option.

Next would be a desk.  The hubster and I liked this style of desk the last time we were at Ikea.

I like the legs of the white one better, but not sure it's worth $40 extra, but it could be considered extra storage.  The one that we saw on display was more of a drafting desk and had sturdier legs like this:

You can see that these legs allow you to raise one side higher than the other.  The glass top options are $160 and $120.  The legs we like only come in white and birch and the expedit only comes in birch, beech, and black brown.  I'm a fan of dark furniture.  I wouldn't mind white, but it wouldn't match the room.  I like the idea of a frosted glass desktop as well.  Something like this:

The furniture buying won't start until the shopping ban is over and when the room is finally cleared for furniture.  At least that will give me time to better plan things out.  Also, it doesn't hurt to look.
