These are heritage buildings and it is mandated that they renovate it periodically; in MAS's case, I suppose once in five years, meaning repainting of the facade (may include internal walls as well) and seal any leaks and rectify electrical and plumbing works, just as we do at our homes. Very soon we may see our familiar red. Missed taking a pic of the samples (3 shades, red, maroon, and brown) that they had done recently.
