In speculative fiction, the architecture of alien species will often be oddly uniform across the board, with no variations owing to different styles being in fashion at different times, local environment or available materials. Might also apply to futuristic human cultures: it is rare to see a future city with architecture from different periods side by side, despite this being the norm in real life. Of course, while real-life housing developments are uniform in style and age, one does not usually build entire cities from scratch like this. One notable exception is the city of Brasilia, which was built quickly in a uniform Modernist style to be a new showcase capital for Brazil (as were UsefulNotes/WashingtonDC, [[UsefulNotes/{{Australia}} Canberra]] and, even earlier, St.Petersburg and Constantinople) and has been criticized for its bland and antiseptic appearance (as the others named [[TrueArtIsAncient had been when]] ''[[TrueArtIsAncient their]]'' [[TrueArtIsAncient prevailing architecture was dated but not yet antique]]). See the "Future City" section at [[http://davidszondy.com/future/city/futurecity.htm Tales of Future Past]] for more on this. Not to be confused with DaysOfFuturePast.

A special case of PlanetOfHats: it would usually be too much work to give an alien species or future humans more than one architectural style. The ShiningCity is usually described like this.

Compare CrystalSpiresAndTogas, AdvancedAncientAcropolis, CityOfGold. Contrast UsedFuture, TheConstant. Space Brasilia will often be more [[CrapsaccharineWorld cynical]] and filled with inhuman [[{{Bizarrchitecture}} concrete architecture]], {{Futuristic Superhighway}}s, and creepy lawns. Compare {{Zeerust}}. Our heroes will long to return to the {{Arcadia}} of good old planet Earth, which is ''never'' StepfordSuburbia.

When it is not CityNoir, your typical CityInABottle setting will usually be this. In which case it will be the hero's job to [[EscapeFromTheCrazyPlace escape]].

Named for the tendency of such settings to be filmed in set-piece futuristic towns [[CaliforniaDoubling like Brasilia]].

[[folder:Comic Books]]
* Kryptonian architecture in the {{Superman}} comics. Also in different incarnations of the Bottle City of Kandor.
* While a JackKirby futurescape is immediately recognizable as such, he was certainly capable of varying it. Certainly nobody would mistake a picture of [[NewGods Supertown for one of Armaghetto.]]
* Initially averted in ''JudgeDredd''. The very first story had a criminal holed up in the Empire State Building, which is now dwarfed by city blocks, [[HarsherInHindsight the World Trade Centre is destroyed in a later story]] and the Statue of Liberty was still standing, but was later destroyed. Gets played a bit more straight after ''The Apocalypse War'', where half the city gets nuked, presumably destroying most of the older buildings.
[[/folder]]

[[folder:Film]]
* Averted to a ridiculous extent in ''Film/BladeRunner''. The mixture of architectural styles is pretty much realistic, apart from the notable lack of air-conditioning. But the streets filled with uniformly '50s style cars while futuristic spinners zoom overhead ?
* ''Film/MinorityReport'' also averts this by being pretty effective at depicting a world with a variety of architecture of different ages and styles. This is actually a ''plot point'' at the very beginning.
* [[ProudScholarRace The Planet Vulcan]], quite logically, in the ''Film/StarTrek'' reboot.
* Partial example: most of the worlds in the ''StarWars'' universe, in addition to being {{Single Biome Planet}}s and/or PlanetOfHats. Partially averted with the CityPlanet Coruscant, where different parts of the planet are dominated by different buildings: the predominance of ''Metropolis''-esque art deco scyscrapers there can be [[JustifiedTrope explained away]] by the Galactic government's capacity to rebuild entire areas from the ground up. Moreover, some of the alien species seem to be adapted to their various forms of architecture, that is when there is not [[ItsASmallWorldAfterAll only one settlement to be found]].
** In the Expanded Universe, this is more thoroughly averted: while the upper levels are rather uniform CrystalSpiresAndTogas, the lower levels reflect older methods and styles of building- because after Coruscant [[CityPlanet ran out of room]], they could only build straight up. This makes Coruscant an odd ''vertical'' aversion.
* Averted in ''Film/{{Metropolis}},'' where Rotwang's laboratory is in an old Gothic church [[TheConstant still standing]] among the futuristic skyscrapers.
[[/folder]]

[[folder:Literature]]
* [[PlayingWithATrope Played with]] in the [[Literature/TheCulture Culture]] novels by [[Creator/IainBanks Iain M. Banks]], where the architecture of different civilizations are suggested as being representative of their cultures in different ways. The neo-imperial Azadian cities in ''The Player of Games'' are described as sprawling masses of construction, decay, and reconstitution, as though the entire civilization were a massive bacterial colony grown too large for its Petri dish, while most socially and technologically mature societies, of which form the communistic Culture represents an ideal, tend to manufacture habitats as concerted projects to meet specific well-understood needs, so that Culture ships and space habitats favour a simplified, flexible architecture that nevertheless contains immense microscopic diversity in the way individual species, subcultures, and populations customize the minimalist designs of their habitats to suit their living preferences and aesthetic interests[[note]]in fact, the Culture (and Banks), take great pleasure in this fact of utilitarian solidarity in diversity, it's one of the main points of the books[[/note]].
* The LoisMcMasterBujold novel ''[[Literature/VorkosiganSaga Brothers in Arms]]'' describes future London as averting this, being a weird mixture of architectural styles. [[FutureImperfect Creepily]], when the style of "old London" is described, it is a late 20th century style, implying that all of the older architecture London is currently known for no longer exists. Given that the same book mentioned ''submarine rides on the lake Los Angeles'' it's safe to assume that Earth survived ''a lot'', and [[EarthThatUsedToBeBetter not all of it was pretty]]. The planet Barrayar is described in similar fashion. The capital of Vorbarr Sultana is a mishmash of old and new architecture, while newer cities like Hassadar are pure SpaceBrasilia.
* Averted in Creator/AlastairReynolds' Literature/RevelationSpaceSeries, particularly by the shantytown-like cities on Sky's Edge. The "historical" buildings were actually often built from cargo containers and prefabricated materials and the newer ones are more natural. Most town squares in the oldest cities of Sky's Edge have a triangular shape, since they were built around the triangular atmospheric shuttles that brought the colonists to the planet's surface from the orbiting GenerationShip. Also, in the same series, Chasm City on the planet Yellowstone has enough variability in its architectural history, even though it's a typical high-tech metropolis.
* Literature/TimeScout averts this. The architecture on the time terminal is outlandlishly diverse, with everything tending to look like the art and architecture of the nearest tourist gate.
[[/folder]]


[[folder:Live Action TV]]
* In ''Series/DoctorWho'', Zoe comes from the [[{{Zeerust}} space-age 21st century future]]. The only time we see her home city, it fits this trope (and, indeed, the original script suggested Brasilia as a model).
* There are indications this is the case with Minbari cities in Series/{{Babylon 5}}. The ones we see are very uniformly the Crystal Spires style, and Delenn once compared Minbari cities, which don't change for a thousand years at a time, to her going away for a week and coming back to find major parts of the station reconfigured in looks and function.
[[/folder]]

[[folder:Video Games]]
* {{Invoked}} and {{Justified}} In ''Franchise/MassEffect'', due to the series' love of classic sci-fi tropes.
** When you visit Ilos, the last planet in ''VideoGame/MassEffect1'', you are able to see a ruined Prothean tower off in the distance. It seems to be identical in style to the skyscrapers on Feros, a distant planet where the environmental conditions seemed quite different. [[spoiler:Justified in ''VideoGame/MassEffect3'', which reveals that the Protheans were in fact a highly aggressive imperialistic monoculture more than advanced enough to build in that style anywhere they wanted. It makes perfect sense for them to have enforced a single style of architecture as a monolithic demonstration of their power.]]
** In ''VideoGame/MassEffect2'', Illium is similarly full of giant skyscrapers all of similar design - Actually an InvokedTrope, a literal Space Brasilia meant to demonstrate Asari superiority. In ''VideoGame/MassEffect3'' it's revealed to be a carbon copy of Thessia, [[spoiler:and the Asari are revealed to be the heirs of the Protheans in every way, including their arrogance - they're just a lot more passive-aggressive about their plans for creating a galactic monoculture.]]
* It's possible to avert this or play this straight in ''{{Spore}}'', since you can choose similar buildings for every colony, or have each planet with its own unique style.
* Can happen in the ''Rush Hour'' expansion to ''VideoGame/SimCity 4'': you can choose from the six styles of building that will show up in your city; these are by default set to cycle every five years. This can lead to a fair number of very large neighborhoods looking very, very similar. However, you can change things up: in one direction, you can have the architectural styles build all at once; if you find that it makes things a bit ''too'' weird, you can keep the cycle but set it to change faster (e.g. once a year), which creates smaller single-style neighborhoods (which is actually mildly realistic for an expanding city). On the other hand, you can also slow the cycle or even ban up to five styles outright (if you like the Brasilia effect).
* ''MirrorsEdge'', [[EverythingIsAnIPodInTheFuture of course]].
[[/folder]]

[[folder:Webcomics]]
* Averted in ''TheInexplicableAdventuresOfBob,'' where we've seen a few different sets of alien buildings. The Fleenians' buildings are mostly [[http://bobadventures.comicgenesis.com/d/20100302.html boxes or pyramids.]] The [[OurDragonsAreDifferent dragons,]] being borderline SpaceAmish, are said not to build very many structures, but because they're [[GiantFlyer giant fliers,]] such buildings as they do erect tend to be very [[http://bobadventures.comicgenesis.com/d/20091128.html big and tall]] (but in the ancient past, they did have [[http://bobadventures.comicgenesis.com/d/20100518.html true cities).]] The one Nemesite city we've seen had [[http://bobadventures.comicgenesis.com/d/20100828.html weird, soaring, curvilinear structures.]]
* The city of Wonder in ''LastRes0rt'' -- which makes sense enough, since it was built at the same time as the rest of the space station the show takes place in.
[[/folder]]

[[folder:Western Animation]]
* The CityInABottle in ''WesternAnimation/AeonFlux'' was almost ''filmed'' in Brasilia, but due to infrastructure problems they decided for Berlin and Potsdam, Germany.
