What type of building requires the services of an architect?

When considering the types of buildings that require the services of an architect, it's essential to understand the complexity and scale of the project. An office building over 10 storeys typically falls under regulations that necessitate professional architectural input due to factors such as structural integrity, safety codes, zoning laws, and the need for specialized design knowledge. High-rise buildings require careful planning regarding people flow, emergency exits, and integration of mechanical systems, all of which are areas where architects play a crucial role.

On the other hand, while single-family dwellings may sometimes benefit from an architect's expertise, they are generally not required to engage one unless specific factors or local regulations mandate it. Parking lots and public parks typically do not necessitate the level of architectural design that larger and more complex structures demand. Hence, when evaluating the need for architectural services, the office building over 10 storeys clearly stands out as a project requiring an architect's involvement to ensure compliance with stringent building codes and to provide effective, functional designs.
