This should probably go in the Luhr's thread but since the other article is here, I'll just continue here I guess.
Did some digging around the Recorder's Office website and there are quite a few things related to a hotel on that site from HHLUHRS LLC.
An Agreement was signed between then and the city in May 2010 that has a lot of stipulations on the projects, but unfortunately it seems they have already missed all the deadlines, which can't be a good sign.
The original Agreement says the develop intends to demolish the Central Building and construct an approx. 315 room hotel (may have as many as 415 rooms) with a bisto bar, 5,350 st ft of meeting space, fitness center and swimming pool.
It goes on to say that by Jan 1, 2011, the developer needs to have an agreement with a major hotel brand in place.
By July 1, 2011, the developer needs to have all building permits and commence construction. (a 12 month extension may be granted)
Within 6 months of the commencement date (July 1, 2011), the foundation for the hotel should be completed.
Within 24 months of the commencement date, the project should be completed.
There is a Memorandum of Development Lease that was entered into on Oct. 1, 2011 which is basically HHLuhrs (the developer) leasing the land back from the City of Phoenix (for tax purposes) so there is progress being made on this actually moving forward.
This is the site map and future location of the hotel.
