The controversy and politics that beset these two buildings were to pale into insignificance beside the troubles that surrounded Scott's third CIE commission. This building was the first large modern building to be built in the city of Dublin and the first major public building to be built in Europe after the Second World War. It was also to bring him acclaim and attention from the public - this was the Dublin Central Bus Station, to be known as Áras Mhic Dhiarmada or Busáras. Busáras was to win Scott the Royal Institute of Architects of Ireland Triennial Gold Medal for Architecture and many accolades from architects all over the world. It was not always so. During the early construction process much controversy was circulating about the building in newspapers and journals.

By 1945, Scott had surrounded himself with a young and talented team, most of whom were recently out of college or indeed still studying. The team included Wilfrid Cantwell (born 1920), Kevin Fox (born 1922), Patrick Hamilton (born 1921), Kevin Roche (born 1922), Patrick Scott (born 1921), and Robin Walker (1924-1991). Many more worked on the project to a lesser extent. According to Sean Rothery who worked for Scott from 1951, Scott always let his team work on their own and he rarely interfered. This engendered in the young architects a sense of importance and self-belief. It was this group of architects were responsible for design of the building.

He was a bit like Diaghilev. It wasn't so much what he did himself as the fact that he assembled a group of very talented people around him, stimulating a lot of creative thinking, which made things happen. He was more of an impresario than an architect.

Wilfrid Cantwell was the main designer of the building and was principal architect until he left Scott's firm in 1947, at which stage the main structure and façades were already designed. The importance of Patrick Scott on the project is well known as he was responsible for the internal and external decoration, but the impact of the others is not quite so publicised. Kevin Fox was one of the main assistant architects on the project and most of the perspective drawings of the various concepts were drawn by him. He took over as principal architect after Cantwell's departure and was responsible for most of the detailing. Kevin Roche only worked on the design for a short time but contributed to the external appearance of the finished building on the pavilion storey. Patrick Hamilton also played a very important role in the design. Apart from being responsible for many details, he ran the drawing office which he run strictly and, more than anyone, was responsible for getting the building up. Robin Walker was responsible for the design of furniture and interior fittings.

Although acclaimed as the architect of the building it now seems that Michael Scott had no design input into Busáras other than in a supervisory guiding role. It was Wilfrid Cantwell who was responsible for the main elevational treatments and plans. In 1945 when Cantwell joined the firm straight out of college, little progress was being made on the design of the building. Newspaper reports state that the City Corporation did not receive detailed drawings for a long time after initial planning permission had been granted. The architect who had responsibility for the initial sketches was Barry Quinlan and progress was slow. Cantwell is said to have "muscled his way onto the Bus Station job" within a couple of months of his joining the practice and then completely took it over. This he achieved by the constant harassment of Quinlan while he was working until he got to the stage when he just relinquished control of the job - Cantwell had an abrasive and pushy personality. The finished design that was built was Design No. 12 by Cantwell and the structure was completed by the time he left the practice in 1947 to work on his own.

Wilfrid Cantwell tells a different story. According to him, two architects Nolan and Quinlan were all 'at sea' on the project and it was in deep trouble. The architects had been approaching it the wrong way, and he suggested an alternative proposal which Scott liked. Quinlan and Nolan left shortly afterwards to start their own practice and Cantwell was immediately appointed principal architect. Whichever the case, what is not in doubt is that Cantwell was responsible for the way the building looks today.

According to Uinseann MacEoin, who was working in Scott's office at this time, the pavilion restaurant was designed by Robin Walker while just out of college. Throughout these years many young architects left Scott's practice as relations between the client and the practice soured - at some times relatively in-experienced architects were left in control of the job. Robin Walker stayed on and became a partner in the last incarnations of Scott's firm, Michael Scott and Partners in 1958 (which later became Scott Tallon Walker in 1975). Between 1945 and 1949 Walker alternated between working for Scott and travelling abroad to work and study. He worked for Le Corbusier (1887-1966) at the Atelier in Paris and Skidmore Owings Merrill. He also studied under Mies van der Rohe (1886-1969) in the United States. Although MacEoin recollects that it was Walker who was responsible for the pavilion restaurant, Patrick Scott maintains that Walker was only responsible for the furniture in the pavilion while Kevin Roche, later to work with Eero Saarinen (1910-1961) in the United States, worked on the overall design of the top floor pavilion.

So many people worked on it at some time or other - Kevin Roche did some work on the pavilion floor. At one stage he had a spire on one end on a sketch plan.

Kevin Roche himself wrote:

Wilfrid Cantwell and Kevin Fox were the primary architectural assistants working with Patrick Scott on this project. Wilfrid was the project manager and planner. Together with Patrick Scott, Kevin was probably the strongest designer involved; Fred Hilton worked in a somewhat lesser role. My contribution was minor as I was engaged in a number of other projects including the bus garages in Donnybrook.

Roche left the firm in 1948 to go to America after completing sketch plans for the pavilion and Walker detailed them. Walker was a couple of years behind the others in college and would likely have had less creative input. MacEoin would have only joined the firm several months before Roche left, so it is possible that Roche was easing Walker into the project prior to his own leaving. Of those who left the company in later years Scott always maintained that with the exception of Kevin Roche, they never rose to the same heights again as they did with Busáras.

Apart from the ones who stayed with me who did marvellous buildings, none anything much afterwards, for some curious reason. Cantwell was a very good architect, first rate when he was young. So was Kevin Fox, first rate when he was young.

This is true to the extent that Cantwell and Fox never again were responsible for a building as large, as complex or as acclaimed as Busâras through the remainder of their careers. Scott would have wished to portray himself in the best possible light and would try to suggest that he was responsible for bringing the best out in them. Wilfrid Cantwell continues to work on his own, specialising in small projects and ecclesiastical architecture, while Fox worked abroad and then went into education. Scott's dismissal of Cantwell may also be attributed to Cantwell's less rigid approach to modernism in later years as he felt that architects should 'take each job as they come, and assess the best approach' or equally to his departure because Scott would not make him an associate in the firm.
