All classes can construct buildings which are class exclusive to construct. There are 3 buildings per class which must be built in a specific order. The effects and costs of these buildings vary based on the class. For more details on them, see the corresponding class page:
Mystical city upgrades allow the construction of unique buildings in your cities, dependent on the explored structures that may be found in your city's domain. Most of these give strong buffs to specific units build in the city, stimulating the production of a single kind of unit in the city. Others enhance the city in defensive ways, for example by regenerating its walls and raising the dead. See Mystical City Upgrades for a complete list of structures and effects.
You're not allowed to build the same building more than once. I noticed that this rule is easily overlooked, especially in 7-player games and when the table is not that big (and so the cards need to be partly stacked).
Of course there might be other side effects, as when the builder (or neighbours) already made use of the illegal building. It could be very hard to retrace everything, so I guess it'd be best not to try to undo any side effects.
If it is too late to undo, option 3 is your best bet (assuming they can build their wonder). If it's been more than 2-3 turns, and other people have been using their resources, I might consider letting it stand. Especially true if there are a lot of people who haven't played before in the game.
Our group's practice has been to discard the extra building and treat it as if the player discarded the card for 3 gold. 7 Wonders is a fast game that I try to keep the game moving at a brisk pace, and the 3-gold discard eliminates the extra decisions (should I build a Wonder stage, can I afford to, which neighbor should I pay, wait did my neighbor even have the resources I needed to buy all those turns ago) that would otherwise keep the game waiting.
It's relatively rare that there are important side effects that need to be undone (rarely do you need to buy more than one of a resource from a single opponent) but it should be straightforward to reverse a military victory/defeat if there's been an age ending in between.
Since this happens most often with science buildings, which means you won't really have gained any new capabilities with them, we just have the player discard for 3 gold and move on. The other one that it seems to happen with is basic brown cards, which may have enabled the player to build something they shouldn't have been able to build. If we can identify any of those buildings, they'll have to hand over payment to a neighbor as well. That's all the unwinding we've ever done, really.
Trees do plenty of work to sequester carbon on their own, but many forests are not as healthy as they should be due to fire suppression and climate change. This can leave trees vulnerable to large scale insect damage, fire or drought, and much of the carbon stored by forests is lost to the atmosphere as trees die.
The U.S. Forest Service is committed to the storage of carbon using wood products through the green building and wood products strategy. This strategy involves putting people to work in rural communities, enhancing resiliency of our ecosystems, and sequestering carbon by promoting the use of wood products in large building construction.
By using wood instead of, or along with, concrete and steel, large amounts of carbon can be stored in the walls of homes and offices, significantly reducing emissions associated with the production of other materials. Also, using sustainable timber harvests for emerging wood product technologies like cross-laminated timber, can stimulate local economies in timber country while sequestering carbon in long-term wood products.
Cross laminated timber is a wood panel made of layers of dried lumber boards stacked in alternating directions, glued and pressed to form solid panels. These panels have extraordinary strength and are being used as walls, roofs, and floors. D.R. Johnson Mill in Riddle, Oregon announced recently that it will be the first U.S. mill certified to produce cross-laminated timber for high rise construction.
And in the private sector projects like the Bullitt Center in Seattle are showcasing the use of sustainable, Forest Stewardship Council certified wood products to efficiently create new buildings that will last and become testaments to sustainable forest management. The Bullitt Center sequesters 1,703 metric tons of carbon in its walls.
The trees in our national forests can help mitigate the effects of climate change in so many ways, and the Forest Service is committed to helping neighboring communities by promoting sustainable development with trees and wood.
Approximately 30,000 travelers visit Stone Town per year, a number that reflects the importance of the tourism industry to the livelihoods of many Zanzibaris. Both buildings also host a number of public events every year, but have the capacity to do even more if restored. Despite high visitation and acknowledged importance, both buildings are in poor condition and at risk of structural failure due to environmental challenges and a lack of conservation work. In November 2012, a large corner of the House of Wonders collapsed, taking with it several historic iron pillars and threatening the structural integrity of the building and its faade. The roofs of both buildings are in a precarious state. They were included on the 2014 World Monuments Watch in order to draw attention to their plight both locally and internationally.
Watch Day took place in December 2015, with participants including representatives of government, CSOs, NGOs, business groups, academics, and the general public of Zanzibar, as well as representatives of the international community (embassies, NGOs, foundations). The purpose of the event, which included a guided tour, was to raise awareness of the general threat to the Palace and to demonstrate broad political consensus for action.
On December 25, 2020, a section of the most iconic building, the House of Wonders collapsed with the tragic loss of two lives. In January 2021, as part of a mission organised by UNESCO, WMF sent a team of structural engineers and architects to advise the Zanzibar government on emergency stabilization of the remaining part of the building to save the building from further collapse.

Buildings and Wonders become unlocked as you research your way through technologies, and provide benefits to the cities they are constructed in. Each requires an upfront payment of Gold(except Longhouse and Progress, which requires 0 Gold) but not every city requires every building. The Gold payment is fully refunded if you cancel the construction before it completes.
Note that Wonders are unique buildings - the first Nation to build that Wonder prevents any other Nation from being able to complete or start the Wonder. Only be burning down the city which has the wonder, makes it available again.
Shrines reduces the production cost of wonders by 5%. The Pyramids earn you 2 faith per second for every wonder in the same city. Some wonders offer you a free building in the same or all cities. Wonders will not be built by auto-building, which can be annoying in the case of the Great Library (which will act as the library) and the Great Ziggurat (which will act as the temple).
Street art is ephemeral by essence. This piece will disappear at some point. Somebody will someday will build over the walls, or they will get defaced or knocked down. But we will always have the memories of the moments we spent there, the emotional bonds we made. When we left, people cried, and tears came to our eyes, too. The experience of Perception was all about this. It went far beyond the artistic achievement and challenge.

Buildings and wonders in Interstellar Space: Genesis can be constructed in colonies once the prerequisite technology is discovered by placing them the construction queue. Each requires an open building slot (even Orbital Stations) and a per-turn maintenance cost in BC.
The total number of Building Slots in a colony is determined by the colony's Infrastructure, which in turn is limited by Planet Size. This makes large or huge worlds best suited for Empire Buildings and Wonders.
Planetary buildings can be built in every colony subject to Building Slot constraints and the limits of your Treasury. Due to these limits, it can make sense to scrap some buildings important for the early growth of a colony such as a Cloning Facility in favor of other buildings once the colony is fully developed. For the same reason, you may want to be selective about what you build in a colony depending on its specialization and exposure to enemy forces--an Airspace Facility may make sense in a border colony but not one deep in your empire's interior, and a Space Elevator might be limited to colonies devoted to ship production. Bonuses from planetary buildings only apply to the planet they are on.
Empire buildings can only be built once in each empire. Some provide empire-wide benefits while others (Capitals) provide a bonus only to the colony itself. The latter should only be built in colonies that are going to produce a lot of whatever that bonus applies to--ideally large or huge planets with high Morale and other buildings benefiting the same resource.
Wonders can be built only once in the galaxy. Each requires reaching tier 3 in one of the Culture trees. All provide some empire-wide benefit, while some also provide a benefit to their home colony as well. The Galactic Space Port is particularly powerful if you are missing any type of Strategic Resource as it immediately grants one of each, opening up the corresponding technologies for research.
