Home offices don't need to be boring workspaces that do absolutely nothing to inspire you!
I agree that setting up and decorating a home office is not quite the easiest thing to do... But with some creativity and with some expression of your personality, you can create a space that rings true for you... that lets you express yourself and very importantly - helps increase your productivity.
My home office has seen some changes over the years. It started with a little black Argos desk in the living room (which had to be moved to the kitchen at Christmas in order to make room for the Christmas Tree).
When we moved home I was lucky enough to get a small room for that little black desk but as soon as I purchased a 22-Inch graphics tablet, I knew my little black desk days were numbered.

I needed something with a little more space, something that could accommodate my desktop computer, printer, monitor, and 22-inch graphics tablet.
So, with a quick look on the Facebook marketplace, I came across a large beach effect desk for €30 that should do just the trick.
Less than 24 hours later I had a bigger desk and my little black desk found a new home in my sons' room. It had served me well.

Anyway, I was never truly happy with the larger desk or my home office. It just didn't have that WOW factor. Yes, I loved the fact that I now had a room. It was no Google Headquarters but it was a step up from the living room but I envied some of the home offices that I saw on Pinterest or YouTube.
I had a fair idea of how I wanted my office to look and the first step was getting rid of the cream walls. I wanted something bright and decided to go with a light grey colour. The 5-litre tin ended up been way too much but having it washable was important as any parent will tell you.
The 5-litre tin cost me €58, add in another €15 for the rollers, brush, and masking tape and we have a grand total of €73 euro.
The next step was putting up some shelving in order to store my camera, lens, and a few other bits and pieces. I already had the brackets but the two shelves set me back €25 along with another €12.50 for the black wood stain. So, we have a total of €37.50.

Now you can't have a home office with just four bare walls. The next step was to get some pictures up. Been a graphic designer who sells wall decor online, this part wasn't a problem for me. The illustrated poster I done of myself and my wife took the centre spot. Around that, I wanted to get in some different shapes of pictures along with some good vibrant colours.
Most of the frames I had from before but I would estimate about €60 would cover them.
