From an architectural masterpiece in Singapore to an idyllic retreat on the Gulf of Mexico, these are this month’s four featured notable properties for sale over $20 million.

In ancient mythology, Aurora, the goddess of dawn, would dance across the sky announcing the arrival of the sun each day. An address on Aurora Lane, then, feels fitting for this one-of-a-kind home, which with its southern orientation and walls of glass revels sunlight from morning till night.

A home is much more than a place to rest your head at night—it’s a personal sanctuary and the starting point for everyday living. With the hustle and bustle of modern life, it’s no wonder nature-inspired décor is appearing in luxury homes across the country. This approach to interiors mimics the hues, textures, and materials of the outdoors, and helps to recreate the feeling of peace often inspired by a walk in the woods or an afternoon by the sea. To add serenity to your home, incorporate the following six trends that make the most of bringing the outdoors indoors.

No matter how familiar and comfortable a home may be, there will always be opportunities to make the space even more unique. Spending additional time at home has inspired innovative solutions for working, entertaining, and relaxing—and these four luxury homes do an exceptional job of transforming common areas into creative spaces that make everyday living even more enjoyable.

In keeping with the motifs of its inspiration—the hôtels particuliers of France—this stately manor in Pacific Heights is gracefully positioned “entre cour et jardin”—that is, between a refined entry courtyard and a glorious backyard garden. Its undeniably classic architecture and influence notwithstanding, the residence is a perfectly modern milieu, at ease with contemporary fittings and furnishings as well as technological comforts and conveniences. Its generous scale, lofty ceilings, expansive wall space, and thoughtfully placed lighting create the ideal environs for art.

Water features have the ability to transform an ordinary property into something extraordinary—they become a locus for both drama and history. From idyllic ponds to antique fountains to entrancing infinity pools, an architectural water feature sets a striking scene, no matter if you’re in California or Paris. These four exceptional listings prove that a water statement is a powerful—and memorable—architectural move to make.

“Less is more.” That was the edict of one of modern architecture’s patron saints, Ludwig Mies van der Rohe, and is still a guiding principle for many contemporary practitioners. Geometric shapes, a lack of ornamentation, open, efficient floor plans, and seamless indoor-outdoor living are hallmarks of modern masterpieces. But above all, materials—glass, steel, and concrete—shape the designs.

Blending sustainability with stylish design, these four distinctive homes prove that reducing a home’s carbon footprint doesn’t mean sacrificing luxury.

When it comes to décor, paintings and photography will always enhance a home. But if you’re looking for an even bigger impact, consider a mural or fresco. These are by no means contemporary art choices—murals have been found in caves as far back as 30,000 BC, and frescoes are credited to ancient Roman, Egyptian, and Minoan civilizations—but they are currently enjoying a renaissance.

These estates—in desirable locales from West Coast to East—offer multi-vehicle garages and spacious motor courts that will please any auto enthusiast, whether they prefer rare antiques, rugged muscle cars, peppy speedsters, or luxurious sedans.
