Yes, spending money on the exterior of a building can be worth it. A well-designed exterior creates a positive first impression and can attract more visitors or customers. It also increases the property's value and reflects the owner's or business's identity and status. Plus, a beautiful exterior can enhance the neighborhood's overall look and feel, making it a more pleasant place to live or visit.

I don't think it's necessary to spend a lot on a building's exterior. The functionality and interior are more important. Elaborate designs can lead to high maintenance costs, and the money could be better spent on community projects. Simple designs are often more timeless and elegant. The focus should be on ensuring the building is safe and structurally sound, which is more important than how it looks from the outside.

It really depends on the building's purpose. For commercial buildings, a striking exterior might be necessary to attract customers. However, for residential buildings, the focus might be more on comfort and functionality. Cultural or historical buildings might warrant investment in their appearance to preserve their significance. Budget constraints and environmental factors should also be considered. It's about finding a balance between aesthetics and practicality.
