This buffet is as fabulous as it is functional, thanks to monogramming, a hammered brass case and old-school, crystal barware. Beveled, smoky glass panels surrounding the wall mirror’s four faces echo the buffet’s four panels and pull the eye upward where a pair of shapely gold lamps, in turn, carry it out to the swirling agate wallpaper.

Digitally printed grasscloth wallpaper creates a vibrant foundation for this lounge’s wild personality — even the room’s molding sports a coat of supersaturated turquoise paint. Glasswork on twin lamps and curves-meet-corners geometry on the brass, mirror and lacquer side tables give that exuberant background an air of sophistication.

If you’re Deco-curious and want to splash out with a bit of the style before committing to a larger space, a powder room is the perfect spot to get started — and to make a significant statement without a massive investment. Here, a subtly patterned trellis wallpaper gives way to lavish marble tiles, while an opulent sunburst mirror adds golden gleam. The marbled-and-lacquered sink, in turn, is both tailored and curvy.

The foyer in this lakefront North Carolina home welcomes visitors with a bold, oceanic note, courtesy of lacquered wallpaper with vertical bands of blue and a sculptural piece of bleached coral. Magnificent sconces on either side of a decorative mirror set the stage for nested mercury-glass cylinders in a pendant lamp.
