How to create a macho retreat that men and other homo sapiens will love.

It's the hottest thing on the home front since man discovered fire: the man cave - a refuge where men can be men and rules can be ditched. It can be in a garage, basement, guesthouse or spare room. Each cave is different, depending on what its dweller likes. Trophies, tools, moose heads or motor mags. Nothing's set in stone. But here are a few (manly) tips to get started.

Pick a favorite object (poker table, guitar collection, pinball machine) and make it the focal point of your man cave.

Studies show that men tend to prefer earthy tones: blues, greens and neutrals. Color schemes like purple, pink or anything with the word “glitter,” not so much.

Typical toys for a man cave might include a flat-screen TV (the bigger, the better), comfy chair or recliner, stereo/DVD player, computer, bar and mini-fridge. Furniture should be sturdy, man-sized and super-comfy.

Spills happen, so consider furniture fabrics that can be spot-cleaned or washed. Leather and vinyl are smart choices. You might want to skip carpeting altogether and go for washable rugs instead.

The only fire in a man cave should come from a roaring fireplace or manly smoking device. No scented candles. Much as they might be needed.
