Deletion of Grand Hyatt Islamabad

Comment: At first, I thought this was a clear keep because of . However, looking more closely at the guideline, it says that ''commercial developments can be notable as a result of their historic, social, economic, or architectural importance. '''They require significant coverage by reliable, third-party sources to establish notability'''.'' I find no |reliable sources that aren't to promote the building. I feel a redirect to Constitution Avenue (Islamabad) isn't plausible because looking at the only reference, it is a travel guide, and so the article might be deleted by its' own
