My illustrative plan is more of an exercise in blue-sky conceptualizing since it doesn't likely fit any of the land constraints of the future DLR, but it does break from the Marvel or DisneySea ideas sometimes floated for a distant 3rd Gate...
Five mansions forming a cul-de-sac, each home to a fictional person of renown. By exploring each mansion, the visitor would be able to enter the wider world of that character...
HOUSE OF THE ARTIST
Since this mansion is in the 12 o'clock position, I imagined the park gates, entry street, and central hub in a similar theme: idealized, historic western European styles: beaux-arts, 2nd Empire, Art Nouveau, marble facades, mansard roofs, heavy iron streetlamps, etc. The mansion could be inspired by the Palais du Luxemboug (as with all others, in a scaled-down, forced-perspective way). This - and each - mansion would be fully explorable & interactive and multi-leveled, telling an interwoven tale of mystery & adventure, with many secrets/details to discover upon repeat visits. The northern side of the House continues the Tuileries/Parisian setting: formal gardens, grand facades and a large fountain. The circuitous river (with a steamer stop in each land) becomes the Seine in this land, with an upper & lower embankment. Across the Seine are structures inspired by – but not duplicating (I don’t think actual landmarks ought to be replicated in miniature here, but serve as inspiration for homages) Notre Dame (on the Ile de la Cite) and the Louvre. The former would house a Hunchback darkride and the latter an interactive mystery adventure involving the works of art within (i.e., Da Vinci Code). A sub-land leaves the city behind and moves into the forested outskirts where fairy tales are brought to life in both dark (a haunted castle omnimover) and light (a slow-moving storybook river cruise) ways. Dining & retail facilities are located throughout (e.g., a museum café in the Louvre, a Parisian bistro, etc.).
HOUSE OF THE SPY
Moving counter-clockwise, the next mansion is that of a retired secret agent, containing an array of hidden passages, a training course, communications & weapons rooms, etc. The house and land are based on a historic & romanticized Constantinople/Istanbul. Like Paris, the specific time varies by attraction but it all pre-dates the era of Postmodernism (1949). The mansion itself would be set in a later phase of the era (1920s-40s) with technology such as two-way radio, telephone, early film projector, etc.), whereas the Abdul Aboubil Amir musical darkride would be during the Crimean War of the 1870s. The dominant feature across Bosphorus (river) recalls (but again, does not re-create) the famed Hagia Sophia (housing a cultural darkride) and Galata Tower complex (housing an indoor darkcoaster). Spice markets and a narrow ‘Theives Alley’ offer unique retail opportunities. The Orient Express train is preparing to depart on an elevated train station (this would house an interactive adventure featuring a train simulator (circlevision)).
HOUSE OF THE SCIENTIST
This is the only land & mansion set in the present, or to be exact, the near-future. I was inspired by the curvy Tony Stark’s house in ‘Iron Man’ when I imagined the mansion (there is a helipad for a semi-futuristic helicopter to rest on). The house belongs to a biologist, who searches for interesting life in the rainforests, under the seas and in the center of the earth. While the Volcano and JTTCOTE may seem to recall the Victorian Steampunk of TDS, this version would be set, again, in the near-future, with different queue, ride vehicles, set dressings, etc. Also in the caldera is a submarine research base (simulator). The rainforest portion of the land is home to a terrain-following jungle coaster located (queue and load area is an abandoned research station). There is an extensive, outdoor jungle EMV ride. A sea base (inspired by The Living Seas) leads to an E-ticket undersea ride involving hungry sharks.
HOUSE OF THE MARINER
The land the right of the entrance is reached by the Sea Captain’s Mansion. The house could be assembled (or repaired) from parts of salvaged ships, with docks nearby. Passing through, one overlooks an 18th century port, with elements of both the New England and The Caribbean. Legends of the Sea is POTC in scale but focuses on wider oceanic tales (sirens, Moby Dick, etc.) rather than pirates. Buccaneer references can be found in the Dead Man’s Diamond Mine coaster (Big Thunder Scale) and the live, stunt battles that take place on the lagoon (with cannon fire exchanged between the island fort and the ship). A decrepit lighthouse on a rocky mount houses a free-fall ride.
HOUSE OF THE EXPLORER
The final mansion is set upon an elevated ridge and reflects the Tibetan monestary-style. It is home to an Explorer who’s favored locale is Asia, from the Himilayas to the South China Sea. A new, expanded version of Expedition Everest dominates the Himalayan sub-area. A jungle river rapids ride is built into the foothills of Everest. Moving downriver the architecture and landscape reflect the transition to a romanticized historic Southeast Asia of Burma & Rangoon. An Indy-type ride takes place in Angkor-Wat style ruins. There is an animal exploration trail (akin to Maharajah Jungle Trek, but set in Thailand). Finally, there is a floating marketplace for a unique retail experience.
