I am a real estate developer who has been in the industry for decades.
I can tell you there are times similar projects can have very different outcomes based on finishes.
It is even worse when they are built years apart. This was the case with my last project. For example, the flagship unit, earmarked as a 20-bed hotel and accommodation, included a dated HVAC setup. Ducts were laid all over the premises leading to costly duct cleaning, and the numerous air filters picked for the project were not as effective as the ones used in this modern unit we had just finished. Right now, the HVAC technician tasked with cleaning the HVAC equipment has difficulty keeping up with the repairs to maintain air quality as the ducts age and the filters fall apart. It has been a costly affair that the hotel wanted to avoid with the new unit. Thanks to the contractor and HVAC professional they engaged for the job, the smart HVAC in place has ensured indoor air quality stays optimal at all times. Additionally, every room was fitted with an air purification system that enhanced every visitor’s stay. And if anything breaks down or acts up, one can press a button to request air purification help in a few minutes. The old unit cannot enjoy these features because the cost of installing something similar to a whole-home air purification system could not justify the cost. However, visitors enjoy moderate air purification benefits at selected common areas. If the hotel was the size of a typical home, renovation or even home service wouldn’t be as expensive. Good thing they had enough cash flow to bring up newer units with better fittings and fixtures.
