Start with color - I have a small house and everything in the house is brick or forest green - sounds awful, but the brick goes up to super pale apricot that looks white, the green up to a pale moss. Although the color scheme is different room to room, the colors are the same so it flows without shock. My furniture is small but not dainty - tiny furniture makes your house look like a dollhouse. In the living room, I have two loveseats facing each other, coffee table of two square tables made of black steel with glass top and shelf. I keep them pushed together at one sofa, pull them apart when needed. I have absolutely no idea, but I'm told Simplicity Sofas has furniture that is delivered in parts - moving things around is often a problem in small spaces.
I don't know what to suggest for your kitchen - own or rent? Budget?
