What if you turned the desk so the person sitting is facing out rather than looking into the mirror. Look into getting a square rug for the space. what about some floating shelves for storage on the bike wall? What is around that corner? I found two cool options for the mirror wall one would use command strips to mount artwork: https://www.apartmenttherapy.com/plagued-with-dated-mirrored-walls-5-design-ideas-to-make-them-work-241744 or put a film or decal on them: https://www.spancraft.com/antique-mirror-collection.html

Is the window too low for the desk to be turned with the short "L" part against it? (If your L desk doesn't need to be all the same height, this could be an option. See the Ikea Malm desk with pull-out panel as example of configuration I mean.) (I read the whole thread but might still repeat ideas already shared. Apologies.) You mentioned monitors but I only see one large monitor and your laptop. Is this your regular configuration? (Any glare issues with the window?) For practicality's sake, I'd consider the visibility of wires when choosing a desk. A lot of your renderings show open desks - lovely in mockups but not always so in real life with the inescapable reality of wires. (This is one of reasons I reconfigured my desk to be against a wall, perpendicular to my window. It was floating in the room. Not only were the wires messy (wireless accessories need charging...), I was missing an accessible wall for my visible planning, aka white board.) Some desk drawers are configured for USB charging. How much space do you have next to each window? Could bookshelves on either side make functional sense for you? In the latest mockup, the shelves look to be display shelves. My advice: make sure whatever you display is adding enough pretty to make it worth the dusting. ;-) You mentioned an electrician coming in to add a light? What type of light? I'm not a lighting expert but I have a smaller office than yours with just one overhead light (and a table lamp) and it's terribly dreary on overcast days. Table and floor lamps do help in a space but make sure your overhead lighting is adequate for the room (wattage, type of bulb, placement...). Have you played around with possible layouts or has it been just the designer? I did my scaled room drawing on graph paper and then played around with my little cut out pieces of scaled furniture and came up with 4 possible layouts with Pros and Cons for each. (Sometimes, moving around physical things makes us see things differently.) Continue to be realistic with your work space planning. Knowing yourself and how you work is key to creating a functional space that meets your needs. And if you're already working in this space, you know what's working for you and what's not. Don't lose sight of your functional priorities. It's not just about decor which is why it's a good idea to analyze inspo pics realistically. Don't forget to allocate your budget according to your priorities: is a comfortable chair just as important or more important than the art? etc. and know that the look of things can be tweaked later on, provided enough time, money and energy (an ugly comfortable chair can be recovered, a desk painted, etc.). Hth. ETA: Looking at the current office pictures vs the designer mockups. You have a shredder and a printer in your current office but not sure I see them in the mockups? Offices have a lot of "non-pretty" stuff so make sure your layout accounts for these essentials. If you want them behind closed storage... You also mention possibly getting a lift desk that can be stored away. I caution you in choosing things that might be a pain to use. Have you considered accessories such as swivel arms for monitors or laptop shelves? Sit-stand desks come in many price points with different finishes. Below is one example by a local company. Ikea makes a more affordable version. If you want one, I'm sure you can find one that meets your needs. You can add a filing cabinet or small drawer tower under an open one.

Blue and Teal go together and work well with earth tones. The closeup of the carpet shows threads of blue and teal so of course! There are many shades of teal, so I agree, get your furnishings and decor first, then pick a wall color that goes with them and the carpet.

There are lots of websites that will allow you to try out rugs in your room 'virtually' to see how the rug complements your finishes and furniture. Here are some examples. Also, you might consider purchasing a small-size rug to check for color & quality before you commit to having a heavy, large rug shipped to your home. Good luck.
