The structure has been called by some journalists a response to the criticism of the high price and technical flaws of some of Calatrava 's earlier buildings . The review in '' ' Archiecture ' '' magazine , the journal of the American Institute of Architects , reported : " The building is full of handsome and even some very impressive spaces , but none of the singularly breathtaking ones that have made Calatrava , despite his price tag , so attractive to clients looking for marketing splash to go with their museum wing or train station . It reflects serious attention to detail and the bottom line ; this is the work of an architect actively trying to prove , or at least re-emphasize , his bona fides . " The Museum of Tomorrow in Rio de Janeiro , Brazil , which opened in December , 2015 , is part of the redevelopment of the waterfront of Rio de Janeiro , and opened in time for the 2016 Summer Olympics in that city . The building is sited on a plaza next to the harbor , and surrounded by reflecting pools . The building is cantilevered over the plaza , and toward the sea . and gives the impression that it is floating on the water . Calatrava wrote , " The idea is that the building feels ethereal , almost floating on the sea , like a ship , a bird or a plant . " The roof is equipped with moveable screens that adjust to the movements of the sun . The interior design is what Calatrava calls " archetypal " and simplified , to allow for exhibits in a greater variety of forms and sizes . The museum also includes a number of ecological features ; water from the sea is used to regulate the temperature inside the building , and to refill the surrounding reflecting pools . '' The Guardian '' described it as " an other-worldly edifice that looks like a cross between a solar-powered dinosaur and a giant air conditioning unit " , and declared " it must already rank as one of the world ’s most extraordinary buildings . " Calatrava designed the WTC Transportation Hub in New York City at the rebuilt World Trade Center at the site of the September 11 attacks in 2001 . The new station connects the regional trains of the new PATH with the subway and other local transportation , and also has a large retail mall , replacing commercial space destroyed in the attack . The above-ground " oculus " of the station , made of glass and steel , is oval-shaped , and is long and high . According to Calatrava , it resembles " a bird flying from the hands of a child " . The " Wings " of the above-ground structure were originally designed to move upward to a maximum height of to form a double screen high , but this feature had to be dropped to meet new security standards . The main hall of the station is underground , and the tracks of the PATH system on another level below . The underground station was originally designed so that its roof would open entirely in good weather , but this feature also had to be dropped due to its cost and space limitations
