You have some good ideas but if you're going to sell soon and aren't planning on taking the soffit out, I would just do some minor changes and keep the cabinets (just add a couple cabinets). I wouldn't move the sink but just get a nice stainless steel sink and update faucet. I'd get a stainless stove vent. Remove the wall on the left of the refrigerator but then just do a small pull out pantry on the right of the refrigerator. And, put a cabinet above the refrigerator and make it look built in. A glass backsplash, can lights on the ceiling and pendants above the penninsula. I think a raised counter will make the kitchen/room feel smaller.

As chookchook said in her recommendation about painting, put a drop cloth on the floor. Get a very safe ladder. remove the lightbulbs, and cover the outlets. Turn off the electricity to the chandelier. Then spray it with a mild cleaner (I use one I found at Target that's basically water with vinegar, until it's dripping wet. Start at the bottom and work your way up, so you don't have dirty spray dripping on the bottom of the chandelier.Work your way up and down until the dripping spray is clean. The chandelier may be gorgeous and expensive, but it seems totally out of place in the architecture of the room--more at home in a chalet than a sunny room with a window wall. I would probably try to find a way to get it removed, and sell it to someone who appreciated it better than I.

Rachel, I guess it depends on your definition of 'modern'. If you want sleek and stark and contemporary, then this piece isn't for you. But I agree with Saratoga that to me this is very 'modern' for its time. It's beautiful as is (which is how I would probably use it if the veneer is good) but its not a priceless antique so it be changed up if that's your style and would go better with other pieces in your house to give it a new life. Either way it has soul that contemporary pieces lack in my opinion. It's a little piece of history and a statement about the industrial time it was created. Including the beautiful mirror.

squeakerd - it is really hard to get a perspective on the whole area but if this is part of a much larger area then I feel you need to first decide just what you want as the end result. Do you just want your entire area to be one open plan or do you want to break it down into visually defined areas within the open plan. As you have the area now, I don't feel any cohesiveness between your table and the sideboard, I think I would move the sideboard to the end wall, it looks more like it would belong there, even just by the shape of the room. Definitely a larger rug will define the space better - just be careful of any trip hazard with the door nearby - but before you decide on the rug, consider window dressings and whether you want things plain or introduce some bold patterns and what colours look best in the area. Artwork can go where your sideboard is now, but again think colours and impact of design on the whole area. It is all very well to build a room around one piece, but you need to look at the impact that piece will have on other items and what limitations it could cause. I would suggest you set aside some serious time to look through photos on Houzz, especially if you can find areas similar to yours, till you find what appeals to you, put the photos into your ideas book and use that to build your room. I have found this invaluable in the past and it has saved me many an expensive mistake.
