RESPECT THE BONES, THEN DO YOUR THING

Preservation essentially means “let it be.” Keep in mind the difference between that which is permanent (ripping out the staircase) and what is ephemeral (adding a modern light fixture). Not that it’s always quite so clear; painting over original, natural-finish mahogany woodwork for the first time in 160 years comes to mind! That’s reversible, but only after hard work and environmental impact. Do no harm, then decorate as you wish.

Many decorators gravitate toward trends, rather than considering timeless qualities that have staying power. This book gives you a head start on alternatives—materials and furnishings rooted in the past, but often adapted for modern taste and use. You may discover here a material that your roofer or hardware-store clerk insists “isn’t made anymore.” From wide-plank floors to true linoleum, primitive stencils to Arts & Crafts pendant friezes, big porcelain farm sinks to Sputnik chandeliers: Yes, they still make it! In the last chapter, we even list maintenance and retrofitting options, from compatible wood epoxies to small-duct air conditioning.

Once you can recognize the elements that define the interior and lend scale, you’ll have a good idea of what may fit your house. You’ll avoid doing things that clash with the underlying architecture —a misstep that’d make the next owner itch to remodel yet again.
