Can anyone in NYC ever have enough storage? I'd make a wall of built closets. (Then again, I'm in a Manhattan coop and I'm sure have much less sq footage and likely have more need for storage than in your Brooklyn Brownstone.)

If you don't need storage, what about: a bar, butler's pantry, small library of sorts, or place to display great artwork?

Your floors are a knock out!

Ikea to the rescue. Visit the store and take some photos and measurements with you. There are designers to help you plan the space.

Once done, you can put the cabinets together ( I couldn't do it; my daughter does), or you can opt for in home installation.

Dear Judy and Kendrah, thank you so much for your input!!

In building a wall of cabinets-and-countertop like a Butler's Pantry idea, what would you suggest the style and color of the face, the doors, should be? I want it to relate to the dining room, and to the kitchen. The trick is the right door profile and color. Advice?
