This does not generally happen, at least full copy and paste. What usually gets used are the “details” which are the parts of the blue print modern terminology is Construction Drawings or CDs that show very zoomed in specifics which will be the same in many cases regardless of the global structure. There are major incentives and reasons why full copy and paste doesn’t happen more often some are cultural and some are technical. Culturally because construction projects tend to be very expensive architects sell the client by “building the client’s vision”. So the incentive is to keep making unique buildings every time. In this way architects earn their keep and along the way if they can make their current client happy it may turn into a bigger future project. Technically speaking a new location introduces new variables which the old building design may not meet. For example there may be new risks of earthquakes, hurricanes, tornados, blizzards, high heat/moisture, poor soils (this is the big one). Additionally a new location may require new construction materials or ways of building/methods. Any one of these could lead to large design changes. When the risks might not change our understanding of them might so we may need a new design due to new building code updates. Also building codes and requirements are controlled at the local level so they may vary by legal jurisdiction so even though all else is equal the original design does not meet the code governing the new location. Interestingly there was an open source house project a couple of years ago with the ambition of over designing it so that you could build it in any part of the US. I personally love the idea however I am very skeptical due to the way construction liability works. So say there was a collapse who does the owner sue? Is it the designers all 100 of the people who contributed to the project? What if some aren’t engineers but hobbyists? What if they don’t have engineering insurance? Do they sue the contractor who built it? As you can see it gets quite messy. Construction being an old and mature industry has a lot of regulations about legal responsibility which IMO don’t play well with the modern day tech ethos of “just build”.
