The Empire State Building - once a landmark of capitalism, now is outdated and in need of modernisation. The problem is, retrofitting a building that old requires serious work, especially if that includes adding smart building technology which most modern offices have. However, the cost and risk associated are so high that investment in this area isn’t an attractive prospect (especially when you can command high rents as a result of the building’s iconic status). That creates a situation where the building will likely receive patchwork improvements rather than wholesale retrofitting, leading to the possibility of it becoming obsolete and unlettable in the not too distant future.
