Johnny Carson's Malibu Estate

Situated on a bluff in Point Dume, Johnny Carson's Malibu Estate is a home fit for a TV icon. The legendary Tonight Show host lived on the property for 20 years and it remains mostly unchanged today. The 7,000-square-foot main house was built by architect Ed Niles in 1978 and is comprised of four bedrooms, five baths, a chef's kitchen, dining room, elevator, Asian-inspired lounge, and a living room with 30-foot glazed walls overlooking the Pacific. A master suite occupies the entire second floor and features his and her walk-in closets, onyx bathrooms, and separate offices. Consisting of four acres, the property includes a two-acre garden, tennis court with a workout pavilion, guest house, an outdoor saltwater pool with oceanfront terrace, and access to Little Dume Beach.

Geyserville Vineyard

Situated on six acres of California Wine Country, the Geyserville Vineyard incorporates modern design in an industrial shell. The base of the home is a Sunsweet fruit-packing building from 1930. A frameless glass structure has been inserted into the existing concrete walls to establish the new interior spaces, including an open living area and an upstairs mezzanine housing a sitting room and master suite with a private outdoor terrace. Towering 20-foot glazed panels offer expansive views of the vineyard, as well as the river below. An additional two live/work apartments occupy the south end of the building, as well as a separate caretakers unit.

Big E Farm

Spread across 200 acres of Long Island's North Fork, the Big E Farm is several properties in one. 113 acres sit under vine, as the farm is home to a fully operational, award-winning vineyard, complete with multiple buildings and barn, a gallery, tasting room, and culinary center, and three cottages. Elsewhere on the property sits the massive Manor House, with five bedrooms, including a well-appointed master, five and a half bathrooms, four fireplaces, a professional chefs kitchen, a solarium, and a full basement with a therapy pool, sauna, spa, gym, and wine cellar.

Migaloo Kokomo Ailand Floating Habitat

Cleverly named after waterlogged masses of land, the Migaloo Kokomo Ailand Floating Habitat blurs the lines between boat and island. Its oil rig-like design is split into several different decks, including a jungle deck with palm trees and waterfalls, a spa deck with a gym and salon, and a garden deck for dining and lounging. The beach deck has multiple pools, barbecue areas, an underwater dining room, a shark-feeding station, and an outdoor cinema, while even more pools — of the infinity type — and balconies can be found on the VIP and guest deck below. A helipad makes it easy to get to and from, and a series of eight engines moves the whole thing around at speeds of up to 9 mph. You can observe all the action from the owner's penthouse, which sits 260 feet above sea level, with a glass-bottomed Jacuzzi, private beach club, and spectacular views.

Lowe Guardians

In London, young professionals are in need of affordable housing and property owners have a surplus of vacant space. Lowe Guardians is connecting this supply and demand for the benefit of both parties. Empty buildings are a target for squatting, vandalism, and high insurance premiums. The solution is to fill these properties with fully employed individuals to act as guardians and in return, they get great low-cost digs. Each space is equipped with kitchens, showering and washing facilities, a cleaner, and WiFi, as well as a communal space that hosts frequent social events like movie nights and barbecues.

Villa Los Leones

Ingrained in the Pointe Milou cliffside, the Villa Los Leones brings Mediterranean architecture to the middle of the Caribbean. The property occupies over an acre on the St. Barts coastline. Its white stucco facade is reminiscent of the homes that dot the coastlines of Greece's Cyclades islands, while both Croatian and Moroccan influences can be seen throughout its four bedrooms An eastern orientation takes advantage of the incoming breeze and sweeping seaward views.

Leapfactory Frame Home

By combining solar components and prefab construction, the Leapfactory Frame Home can inhabit any location. The structure is crafted from environmentally controlled materials and a facade made of metal sheet cladding, while a non-evasive foundation allows for little to no disruption to the landscape. Solar energy powers the home, including the water heating system and energy-efficient, LED lighting. Pair that with an optional sanitation system for complete off-grid living. Floor plans are completely customizable and come in one and two-story configurations with exposed beams, integrated furniture, and fixed furnishings. Glazing ranges from large sliding glass doors, vertical ribbon windows, punctual windows, bay windows, and skylights, providing each structure with ample ways to display the surrounding scenery.

Molokai Ranch

Spanning over 55,000 acres of its native island, the Molokai Ranch comes with much more than pastures and livestock. The property is picturesque Hawaii with water-front cliffs, rainforests, and beaches. Along with the cattle operations, the purchase also includes two resorts, two golf courses, and acres of residential lots, commercial lots, and oceanfront resort land for future developments. The coastline stretches more than 20 miles to the island's south shore which contains 14,000 acres of reef habitat.

Nomentana Residence

Bordering White Mountain National Forest, the Nomentana Residence sits like a modern concrete fortress on the waterfront of Horseshoe Pond. The structure is made up of a series of stacked rectangular volumes cantilevered over its hillside plot. A master, guest suite, living room, kitchen, library, and drawing studio make up the 3,000-square-foot residence where a palette of steel and cement runs throughout. Generous amounts of glazing contrast the contemporary design by framing in views of the rugged landscape, while multiple stone terraces and a sleeping porch completely immerse occupants in the forest setting.

Mills Residence

Emerging out of a steep, rocky hillside, the Mills Residence is the embodiment of International Style. Built in 1955 by architect Willis N. Mills, the structure sits as two rectilinear volumes, cantilevered on a jagged ridge in New Canaan, Connecticut. Redwood planks help to disguise the home amongst its wooded setting, while large glazed panels welcome in natural light and views of the forest floor. Internally, the ground floor hosts an updated kitchen, dining room, and double height living area, leaving the more private spaces to occupy the upper level. Sliding glass doors are featured in nearly every room granting access to a series of terraces and decks, Japanese gardens, and a stone-lined pool.

Koda Moveable Home

Most homes — even pre fab dwellings — are meant to stay in one place. The Koda Moveable Home turns that on its head with a design that can go wherever you need. Requiring only 30 square meters of flat ground, it has a lot tucked into its small footprint, including a double-height ceiling in the main living area, fully-equipped kitchen, bathroom with shower and toilet, mezzanine sleeping area, concrete exterior, natural wood interior, and solar panels on the roof. Produced off-site, this minimalist box is delivered via trailer in one piece, meaning it takes only a day to go from installation to move-in ready.

Walden Monterey

Henry David Thoreau wrote about the idea of simple living in natural surroundings in his 1854 novel. With that in mind, Walden Monterey is the realization of that notion. The private community sits on a 600-acre hillside overlooking Monterey Bay. Consisting of just 22 lots, each site contains 20 acres of untouched forest, allowing for total seclusion. Your only neighbors will be the property's 200-year old oak trees. Located just an hour from Silicon Valley, the first eight lots will be available this fall with the remaining becoming available in early 2018.

Petre Island

Whether it's the two homes or the heart-shape of the land, Petra Island is one of the most extraordinary properties on the market. The ten-acre private island sits in the middle of Lake Mahopac, just a 15-minute helicopter ride from Manhattan which you can park on the rooftop helipad. Accommodations include not one, but two Frank Lloyd Wright structures. The first, built in 1950, is a small 3-bedroom, 1-bathroom guest cottage, while the other is a 4-bedroom main house built in 2007. Although the timeline doesn't quite make sense, the home was constructed using plans originally made by the iconic architect. His signature style can be seen in the organic integration of the site's natural rock, built-in furniture, horizontal design, and multiple cantilever decks.

Tavern Island

Just over an hour from Midtown Manhattan and an eight-minute boat ride from shore, Tavern Island is one of the most convenient private getaways. The three-and-a-half-acre island provides both seclusion and luxury in the form of a 6,000 square foot home. Built in the 1930s, the English Country Colonial offers six bedrooms, four baths, a kitchen, and seaside gunite pool that has been visited by both Marilyn Monroe and Barbra Streisand. Other accommodations can be found in the guest cottage, the boat house, and a Japanese-style tea house.

West Creek Ranch

Comprised of four scenic parcels stretching across nearly 7,000 acres and two states, West Creek Ranch is far from just a house. While the home itself is impressive, with eight bedrooms, eight baths, over 22,000 square feet of indoor living space, another 3,500 square feet of covered verandas, a pool, and more, it's the total of the amenities set against the backdrop of wildlife and natural formations that truly set it apart. The property includes rock cliff walls of Colorado's Unaweep Canyon and expansive high plateau country with outstanding views of the La Sal Mountains of Utah. Also on site are a bear and mountain lion habitat, a guest house, a cabin, the historic ruins of Driggs Mansion, a helipad, an airstrip, various petroglyphs, and dinosaur footprints. Former owner Discovery Communications founder John Hendricks' love of space can also be found in the observatory, which has a professional-grade 20" Meade Telescope and rotating copper dome.

Tupac's California Mansion

Although this house has an exclusive location, amazing valley views, and a gourmet kitchen, the real selling point is that "Outlawz, Let no man separate what we create" is carved outside. Written by the former occupant himself, Tupac's California Mansion was the residence of the Death Row rapper at the time of his death in 1996. While the"Made Ni**az" lyrics remain, the rest of the six-bedroom, 6,000 square-foot home has received about a million dollars-worth of updates. Just a few of the amenities include dark granite countertops, stainless steel appliances, a massive master suite with a custom fireplace, private living room, 3 walk-in closets and master bath, outdoor pool and kitchen, and parking for 15.

Cliffe Hill House

Located along the banks of the River Ouse in Lewes, the Cliffe Hill House is a modern home that blends in comfortably with its rural English surroundings. Architect Sandy Rendel is responsible for the design, which sees the upper floor and roof clad in Cor-Ten steel, while the lower areas are surrounded on three sides with floor-to-ceiling glazing so as not to interrupt the views. The open lower floor plan extends from the kitchen's two Lava Stone islands to the main living area, while an open tread oak staircase provides access to the five bedrooms upstairs.

There are also a wide variety of cladding options, from corrugated steel to charred cedar planks, and the homes incorporate features like solar panels, heat recovery ventilation systems, and triple-glazed windows to be as easy on the environment as possible. The building process takes just weeks, as the walls and panels arrive ready to be attached to the company's patented, well-insulated foundation.

The North Face Founder's Patagonian Farm

Situated between the Renihue and Negro rivers in southern Chile, The North Face Founder's Patagonian Farm is an adventurer's retreat.

Along with views of forests, mountains, and rivers, the farm also offers glimpses of the neighboring Pumalin Park Sanctuary's Michimahuida Volcano.

Henry Hall

It's not the Hudson Yards address, the interior design from the renowned Ken Fulk, or the river views that make Henry Hall so appealing. Instead, it's the convenience of having everything you need under one roof. This 225-unit tower will be home to a restaurant from Delicious Hospitality, a lounge, a bar, and a rooftop deck, as well as a fitness center and instrument-stocked Jam Room. The apartments themselves range from studios to two-bedroom units and are appropriately modeled after high-end hotel suites. Features include soaring ceilings, oversized windows to take in the views, Ash hardwood floors, stainless steel appliances, and white quartz countertops.

Pluspuu Log Cabins

Using the latest innovations in Finnish woodworking, the Pluspuu Log Cabins give the traditional mountain home a modern revise. The collection includes ten models, ranging from single to four bedrooms plans. Each home is well equipped for a holiday retreat with saunas, roof decks, outdoor kitchens, covered terraces, and panoramic windows or can be converted to a primary residence. The houses are expertly constructed in Finland by Ollikaisen Hirsirakenne Oy using a combination of a non-settling log system and a column and beam structure, then are installed on-site by an in-house crew. All of the designs are completely customizable or, for the overly particular, whip up a drawing and they'll build a home to your exact specifications.

Smoke-Lyster House

Designed in the mid-Seventies for a mathematics professor, the Smoke-Lyster House uses a hexagonal layout to maximize both space and the views. Offering quick access to Laguna Beach, the two bedroom, two bathroom home sits on a 1/4 acre site, and was built with a mix of materials — including pebble-seeded concrete, redwood, cedar, Douglas fir, Franciscan tile, and raw concrete — that give it a unique character. A wall of glass encases the main living and dining area and opens up a vista that stretches from Dana Point to the south to the Catalina Islands to the west.
