I can't think of homes on a general scale but rather consider each room individually. Each room is like a clean palette to me which needs its own theme / personality - somehow in our previous homes this technique has never resulted in an overall feeling of dissonance
I have two favorites that I am dreaming of right now for our future home - one is the covered porch / garden room and the words are: botanical, rustic, turn-of-the-century
(I imagine lots of Victorican botanical prints, a butterfly collection or two (bought used!), indoor statuary, weathered finials, ticking covered rough daybeds, whitewashed wooden floor and lots of coleus, ferns and ivy spilling out of cement pots.)
The other is our bedroom and the words are: French, bohemian, sumptious
(I imagine here our beautiful Indian block-printed quilt on our low bed, curtains from Anthropologie, our vintage faded Victorican upholstered chair, painted unmounted canvases stacked everywhere, vintage trunks as bedside tables, incense, beeswax candles, a French country look vintage dresser with a silver tray for my jewelry and ornate Egyptian perfume bottles, lots of old books, perhaps even an old grammaphone player, a Moroccan screen with which to create a little meditation nook, small faded dhurries on bare wood floors).
