This mansion in Boulder City, Nevada, looks more like some incredible theme park than a private home. There is a lazy river with a waterfall and a secret grotto, a huge swimming pool and a faux saloon – all in the backyard. The place with a total area of 6430 sq. m (1.59 acres) also features a tennis court and two green lawns. The 858 sq. m (9,245 sq. ft.) mansion has 6 bedrooms, 7 bathrooms, eight-car garage and a vast wine cellar. The price tag of the property is $3,000,000.

This mansion, located near the town of Aspen and the Snowmass Village in Colorado, offers a fabulous view of the mountain peaks. For $29.5 million one can get a luxurious and secluded place with 7 bedrooms, 6 bathrooms and an indoor swimming pool. The total area of the mansion is 1190 sq. m (12,800 sq. ft).

This contemporary masterpiece is located in Beverley Hills and is ideal for a bachelor with means. Three bedrooms, maid quarters, a guesthouse, a movie theater and a top deck with a pool are spread over this gorgeous 8,300 square foot home.

This more than 2800 square foot spacious villa sits atop the Hollywood Hills equipped with the latest technology and an open design. It has six bedrooms, ten bathrooms, home theater, 20 person dining room, a stylish covered terrace with a fire place and of course an Infinity swimming pool with a breathtaking view. Your $12 million will be well spent.

Apparently a French gentleman named Louis Mantin inherited this mansion and a fortune at age 42. He then dedicated his life to the arts, science and his personal pleasure. When he died in 1905, his last wish was that the mansion was to be sealed for 100 years and then reopened as a museum. It cost $4,700,000 to restore it to its original pristine condition.

Supposedly, these are leaked photographs of “Putin’s Palace” that is built near Novorossiysk, on the Black Sea. This mansion is almost finished, judging by the pictures. Its construction is worth $1 billion, according to Russian businessman Sergei Kolesnikov who announced this number in his letter to President Dmitry Medvedev. Prime Minister’s press office denies that this building belongs to Putin. Inside this post, you can see outside and inside photos of this beautiful, luxurious and huge mansion built in Russia.

This is the most expensive house in Toronto, Canada. It is currently listed at $269,800,000. It has a large atrium, multiple kitchens, a tennis court, an indoor pool, a bowling alley, a theater, spiral staircases, and a 4,000 Sq, Ft. master bedroom. Also, its grounds are kept immaculate.

This luxurious Russian mansion is located in a small village near Moscow. It is owned by Vladimir Bryntsalov who owns one of the major pharmaceutical companies in Moscow. It is very stately and obviously worth a lot of money. It also seems that the more money they have, the more tasteless they are…

This very small apartment is located on Piazza di Sant’ Ignazio in Rome, an amazing square in the heart of the capital and is overlooked by a huge Renaissance Church. The beautiful view behind it is Palazzo Grazioli, which is a mansion that is rented by the Italian prime minister. The apartment is 55 sq. ft., costs $70,000, and has a single floor, single bath, single window apartment and a ladder that leads to a platform containing a single bed.

Even though this is Rome, it is still crazy to pay such money for 5 square meters.
