Have you considered moving the workspace so that it doesn't block the window? So the credenza would go to the right of the window. The desk would face the door? Put a tall plant in front of the window to soften the room and add a chair or two with a small lamp table for customers. I may be off on how much room you have...

Consider carpet tiles from Flor.

@Pam P. , Thank for your input. Yes! I did consider not blocking window. Given the desk unit is U shape, the arrangement you suggested ( Desk facing the door ) would not have left enough room for chairs. Any suggestions for rugs?

@ Anne Duke,

Thanks for your input. Are you recommending the tile that sticks permanently to the floor? Any specific color/pattern you recommend?

Any more inputs? How about any of these rugs.

I would appreciate input from you all! Thanks in advance.

I would consider this one, because why not?

(I can't upload photos from the site either, currently)

Just to add, an upholstered chair or two for your clients will absorb some sound. Also, get a plant or two and some wall hangings which will also change the sound.

How about this?

@ashtonchic - Thank you for your input. Does it look more traditional? I like more on the modern side.

Here is a contemporary look. And art.

rug is from Overstock and art is from Art.com

I like the rug as well as the art. Where to get those?

Also, any feedback on the ones I have referred in my post? I am sure you probably won't recommend them as you suggested alternatives but would appreciate some feedback - In case if like to chose from them, which one should I go for.

I would appreciate the links.

Lenhovda Polypropylene rug at Overstock.com. Mark Rothko and Roy Lichtenstein at Art.com. I liked your gray and gold rug but I tend to like more drama.

You might like to think about original art or photographs to hang. There are many studio tours this time of year where you could visit with an artist and perhaps find what appeals to you. Your support of a local artist's work would be appreciated by that community. Good luck!
