The ideal location for the elevator machine room in a 10-storey commercial condominium is typically at the rooftop. This positioning allows for several significant advantages.

Having the machine room at the top assists in minimizing the shaft length between the elevator cars and the machinery, which can lead to more efficient operation. It also provides a better distribution of machinery noise away from the occupied floors, thereby enhancing the comfort for residents or users of the building. A rooftop location can also facilitate easier access for maintenance and repairs, as it often provides a dedicated area for technicians to work without disrupting the use of the elevators.

Additionally, placing the machine room higher up can help with the overall design and layout of the residential or commercial space. It ensures that the floors below can utilize the space more effectively without compromising the layout with mechanical elements. This strategy is commonly employed in building design to optimize both functionality and residential experience.

In contrast, placing the machine room on a lower floor such as the 8th or 9th floor could lead to longer shaft lengths and potentially greater noise intrusion. The option of not needing an elevator in a 10-storey building would generally not be viable, as it contradicts the requirement for vertical transportation in multi-storey structures. Therefore
