Paint can go a long way. Warm color. Change the hardware - pulls.

I couldn't agree with Michael more. Also accessories like area rugs, dishtowels and window treatments can go a long way in changing the style.

You may want to consider adding a cozy, colorful valance with curtains to the window...then during the daytime you could pull the blinds up and out of site.
I love Michael and Becky's idea of paint. In addition to different pulls, you could add some "picture molding" to the front of the cabinet doors with a strong glue made for that...to give them more character. If you do that, caulk around the molding before painting the cabinets. A lot of folks are adding the faux beadboard wall paper to the ends of the cabinets or to islands. You can find it for a great price at Home Depot and it looks real if applied with a little molding around the edge. Rhoda at Southern Hospitality blog has done a lot of tutorials on adding it to kitchen cabinetry. Hopes this helps.

Totally agree with Michael - the paint color is pretty modern with the white an gray. But, if you can swing a few hundred bucks, you could change those countertops to butcherblock from Ikea. Or if not (the countertops are harmless as is!)... for pennies you can add white subway tile from Lowes or Home Depot with charcoal grout to go for the vintage look - change out the hardware to oil rubbed bronze cup pulls and change the knobs to oil rubbed bronze pulls (drill an extra hole!) and pick a vintage style pull rather than a boring old knob! And since the tile is sooo affordable - I'd really push tiling under the window and on either side - take the line of the bottom of the wall cabinets and follow it around the room. Subway tile is meant to be continuous!

Yeah, thanks so much to Rebekah from Kitchenlab for chiming in - you won't get better advice than hers - her kitchens are amazing!

I would first ask what is it that you find modern about your kitchen? Is it the stainless steel appliances? Is in the brushed nickel pulls and knobs? Is it the white cabinets? Is it the pale green paint?

You have a lot of great features in this kitchen and you can take a variety of different routes to change the feel of your kitchen.

The positive aspects of your kitchen are as follows:

You have slab kitchen doors and drawers.
This is a plus because it makes cleaning a snap.
You have no raised or inset moldings for grease and grime to settle in.
A slightly damp sponge is all you need to quickly wipe them down.

If you don't like the color you can paint them a warmer color.
If you miss the warmth of wood, solid wood veneers can be attached to the doors and drawers.
You could add a traditional crown molding at the top of the cabinets.
You could paint them with magnetic paint then paint over them with another color and use your cabinets as a continuous display of family pictures or other things.

The brushed nickel pulls and knobs are classic.
This means your kitchen won't look dated in a couple of years.
This pulls and knobs have no intricate carvings making them easy to clean.
One swipe with a slightly damp sponge is all you need.
Your knobs and pulls won't break or crack or stain because they are metal.

If the color or style doesn't appeal to you check out knobs and pulls online. I would look at some smooth iron heart style Cabinet handles, or porcelain knobs in brown or even colored glass knobs. A great resource is http://houseofantiquehardware.com

Your counter top has a nice play of grey tone on tone colors.
Your counters are a neutral palate and will always be in style
The varieties of tone on tone greys means your counters won't
show every little crumb and speck of dirt.
You can wipe them down easily with a damp sponge

I would not recommend butcher block counters

Thanks so much for all your responses! In answer to tenantproof, What I don't like is the slab cabinets (also they are that cheap paper laminate material that you cant paint glue etc....) I hate them actually it's such a modern profile. I don't really care for the counter tops either. You can't tell in the picture but the way the cabinets are designed you could not add moldings on top (which I would LOVE) I love my appliances. I choose the wall color on purpose to try to go for a "modern retro vintage" look but I'm not happy with it. I've considered painting the room a warm caramel tan color then adding oil rubbed bronze accessories.

Kitchenlab: I love the idea of butcher block and subway tiles. I had actually considered that but I know it would be hard to install with my corner sink. Also I'd have to hire help to install the subway tiles so there would be labor cost. I have also considered putting up the beadboard wallpaper as a backsplash. I would prefer a more traditional/cottagey vibe, that would better go with the rest of my house. What do you recommend to try to work with the slab cabinets? Those really are the torn in my side in this kitchen I just really dislike them!! A LOT! (sorry for all the run on sentences.)

Thanks again for everyone's commments.

Hi there, Did you end up making any changes? Would love to see an updated pic of how it went!

I definitely would add some character to the backsplash, especially since there isn't much of it so it wouldn't be a huge cost. Either a nice subway tile, or even beadboard for the cottage look you like. Warm up the paint and the hardware throughout the kitchen and I think it will make a big difference.

You really have a nice space there! I think replacing the knobs with something a little beefier would be a start. There are so many great options to choose from. I love the bin pulls - I have those too, the originals from 1950-something!

I think that you need to add some "soft" items to the room -- curtains for the windows and maybe even the door (using a curtain with a top and bottom rod pocket along with stationary top and bottom rods similar to what would go on a french door might be an option). Since you are going for a retro/cottage look, you can look for a fabric that has the kind of look you are going for. You can look on ebay for real vintage or go for one of the great reproductions that are out there. Dish towels, too. I think I see beadboard to the right in one of your pictures - so yes, I would bring some of that to the kitchen backsplash or add it as wainscotting to the area below the window and near the door. Another option for the backsplash is wallpaper - a way to bring pattern to the space. Tile is great, but not an easy DYI and more of a $$ commitment.

The green is a "cool" color and even more so together with the white. If you want to keep the green, then bring in some warmth with accessories. For some reason, I see one of those round metal footpedal trash cans in orange along with some other pops of orange and maybe a bit of brown - black would be too harsh, but since you have so much white, I think you need "grounding" with midrange and darker colors as well.

As for the cabinets, you might consider taking a couple of the doors off and replacing them with glass fronted doors in the divided-light style of your windows or door. Not sure how feasible this would be in your case. Another thing to consider is taking the cabinet door off below your sink and adding a sink "skirt" - fabric on a rod - definitely cottage-y and another place to add the softness of fabric.

Changing the hardware is a good start. Adding a window treatment to warm things up will also help. A nice tile backsplash will make the space feel more cozy, as would a new paint color that has more warmth. Try changing the light fixture as well--perhaps a chandelier or pendant light of some sort. Because of the small amount of countertop space you have, swapping the laminate out for stone would be an inexpensive way to make your kitchen feel less modern. Good luck!
