What furniture do you already have? I can't tell from the angle...will the tv go in or on the built-ins? What's at the opposite end of the room?

It will go on top of the build-ins. We are don't want to use any of our old furniture as it is ready to be replaced :)

I think for sure to update the space you should paint the trim The same colour as the walls and for the wall colour I think you should do a really settle gray so you still get the modern vibe but would be easy to add pops of colour to the space:)Also for furniture you should do gray and add different shapes into the room whether that’s with a throw pillow or a painting:) also adding industrial lights to the space will give it a good look:)

Ask first. I bet if you can't paint the built-ins, you can't paint the trim either.

Are the walls white or cream/off white?

I love the photo you posted! I really like shades of gray and blue, but pops of fun color are great too!

I found these pieces and they would really tie into the space:)

It looks like all you need are a few starter items. Why not try a sofa, with two chairs, a rug, coffee table, plants, artwork, pillows, and lamps.
