One of the most incomparable dollhouses ever created, Queen Mary's cousin, Princess Marie Louise, shared her ideas with top British architect Sir Edwin Lutyens to create this Queen Mary’s dollhouse. With over 1,500 artisans and craftsmen, they gifted the dollhouse to Queen Mary, from the people, for her dedicated presence in WWI. It served as a portrayal of how the aristocratic homes might look like during the 1920s - furnished with great detail and miniature items that can be found in the Windsor Castle.

Many items are copies from well-known companies of the time. Miniature shotguns actually lock and load, toilets flush and hot and cold water run through small pipes. On the dining room table, you can find Coleman’s Mustard, and in the kitchen, there are Cadbury chocolates. Near the sinks sit tiny bottles of Sunlight, and in the marble hallway there is a long case clock by Cartier. Additionally, there are elevators that run up and down, a garage full of royal limousines, and six luxurious cars supplied by Daimler, Sunbeam, Vauxhall, Lanchester and Rolls-Royce.

Each bottle in the wine cellar is filled with its appropriate wine and spirit - two hundred bottles of Chateau Lafitte 1875, and five dozen bottles of Veuve Clicquot. Last but not least, the library is filled with seven hundred tiny paintings by well-known artists, as well as over 300 books, including miniature original poems and short stories from well-known British authors. The dollhouse now sits in a room at Windsor Castle, Berkshire, England.

Built by American silent film actress Colleen Moore, this castle took seven years to complete. From 1928 to 1935, a humongous amount of work went into the magnificent twelve-room, fairy-tale castle. There is a drawing room, great hall, chapel, library, princess’ and prince's bathroom and bedroom, attic and a magic garden. During the Great Depression, it toured all of America and raised $700,000 for children’s charities.

Over 700 workers from all backgrounds went into the creation, including Walt Disney, who hand-painted one of the many gorgeous murals on the wall. There are over 500-year-old Chinese royal gems in the house made of jade and quartz, as well as chandeliers made of pure gold and diamonds. Fairy-tale scenes have been incorporated all over the castle, such as Statues of Cinderella and the Prince standing magically in the great hall, and drawings of Snow White & the Dwarfs marked onto the windows.

The famous heiress Huguette Clark, the daughter of American industrialist and copper tycoon William A. Clark, loved dollhouses. It happened in the 1900s when she wanted to buy the Japanese-style dollhouse, but first she needed to gain permission from the Japanese government to use a special cedar reserved for the construction of imperial buildings.

She commissioned Japanese miniatures of houses, temples and tea shops. She had a special interest in Japan and its culture and employed famous Japanese artisans to ensure that the buildings would be historical and culturally correct. She was very demanding and expected much skill from her dollhouse craft-workers. If something was a tad off scale, she would send it back until she was satisfied. However, she was very generous and would pay them unreasonably high!

Considered one of the most expensive dollhouses, this dollhouse is made for kings and queens - a 16th Century Dollhouse, made by Kevin Mulvany and Susie Rogers, husband and wife. They were well-informed historians who had 25 years of experience in creating historically correct and detailed European castles and mansions that look exactly like the original ones, while living in Holt, Wiltshire.

It took over 10,000 hours to create the home and all its detailed furnishings. This six-room dollhouse was commissioned by a private Californian collector at a value of $70,000, in 2009. There are real 16th century cutlers in sterling silver, twenty-two carat, gold-plated decorative leaves along the moldings and skirting of the walls. Each room featured real crystal chandeliers valued at £1000 each, plus furniture made from luxury wood, miniature hand-painted Sevres porcelain dinnerware and a miniature antique statue of Italian sculptor Antonio Canova’s Three Grace Statue.

The rooms are based upon various locations from the 16th century Versailles Palace, the Chateau de Bagatelle and the Palace of Fontainebleau. These are all connected to Marie Antoinette, the infamous female monarch executed during the French revolution in 1793.

In 1686, this dollhouse was gifted to Petronella Oortman, wife of wealthy merchant trader, Johannes Brandt. She had every item fit to scale and commissioned cabinetmakers, glassblowers, silversmiths, basket-weavers and artists to furnish her doll house to replicate her own. There are two beautiful ceiling paintings: one in the nursery room- by Dutch landscaper and painter, Nicolaes Piemont, and one in a marble-floored hallway, portraying Aurora, The Goddess of Dawn. Also in the nursery is a gold-framed mirror, wicker baby chair, beautiful curtains and silk screens. There are another two gorgeous paintings on the chimney-piece, by Willem Van Royen.

In the kitchen, there are the most magnificent tableware and utensils. Oortman’s specially ordered dishes from China sit in a dresser against the wall. And last, but not least, within the kitchen floor is a ‘Hidden Cellar’, seen only when the drawer is removed. The amount of precision that went into the creation of the house and its unique artworks are what bring it such high value.
