ᐅ Carport parking spaces built smaller than planned – acceptable to tolerate?

A construction company built a carport with two parking spaces as part of a new multi-family house project. According to the architect’s plans, the internal width should be 5.30 m (17.4 feet), which means 2.65 m (8.7 feet) per parking space. The carport roof connects on one side to a prefabricated garage and has metal supports on the other side. However, the distance from the garage to the supports is now only 5.15 m (16.9 feet) because the supports were placed noticeably further inward. This means there is a shortage of 15 cm (6 inches), which to me is well beyond any typical tolerance. I’m not sure if this was technically necessary, but if so, the roof should have been made larger to maintain the planned internal dimensions. Originally, the plan was for a fully enclosed structure with only the upper area open. The final product is, however, completely open on all sides, with metal supports extending to the ground on one side. These supports are positioned in a way that the door cannot be opened because there are two supports blocking it, effectively acting like a wall.

This situation is very frustrating, especially since the underground parking spaces are only 2.50 m (8.2 feet) wide and we had planned the carport for a wider/larger vehicle. Is there any way to challenge or address this issue?
