4000 Tower, formerly Kent Tower, the Ramada Townehouse and Dell Webb’s Townehouse, at 4000 N. Central Ave.
is a 23-story combination executive hotel and office building.
The skyscraper started construction in midsummer 1963 and was completed by February 1965.
It featured 275 hotel rooms occupying 9 floors of the 23-story tower as well the adjoining 3-story cabana wing.
The uppermost 12 floors of the tower were leased as office space.

When built, the guestrooms featured individual guest controlled air conditioning and heating, and telephones equipped with message-reminder service, and balconies overlooking the swimming pool in cabana wing rooms.
The structure included the largest hotel convention facilities in the city, including the Los Conquistadores Ballroom to seat 2,000 diners or 3,000 persons for theater style meetings.
A seven-level 1,200-car parking was provided for the new building.
The building was white and gold and similar in appearance to the Del Webb Building.

The bottom two floors of the tower incorporated a drug store, gift shop, men’s store, beauty salon, barber shop, the Aztec Room restaurant seating 250 persons, coffee shop for 150 and Aztec lounge, with entertainment stage, to accommodate 140 patrons.
The entire hotel was comprehensively renovated in 1978.
During the renovation, all public spaces were refreshed and the Aztec Room and Lounge was transformed into the new Saguaro Room and Saloon.
A new hotel tower was also constructed south of the pool, bringing the total room count to 383.
In July 1981, Ramada Inns took over management of the property from the Webb Corporation and it was subsequently renamed the Ramada townhouse.
Ramada had initially intended to remodel the property as a Ramada Renaissance property; however, these plans did not come to fruition.

Ramada ceased managing the property on October 31, 1983.
Management was turned over to LaMancha Racquet Club Inc. in November 1983.
LaMancha closed the property for renovation and reopened in July 1984 as the LaMancha Athletic Club and Hotel.
During the renovation the rooms and facilities in the 23-story tower were removed and replaced with office space, lowering the room count to 171.
The ballroom was converted into the LaMancha Athletic Club, featuring racquetball courts, a basketball court, Nautilus Conditioning room and an indoor swimming pool.
With the opening of the LaMancha, the overall building was renamed Kent Tower.
It ceased using the name Kent Tower in late 1986 and was renamed 4000 tower in 1987.
The exterior of the structure was redesigned in 1987, along with the rest of the complex.

Management of the hotel facilities was turned over to the Hotel Group of Seattle in 1990 and was renamed the City Square Hotel and Athletic Club.
In June 1992, management was turned over to Lexington Hotel Suites and Inns of Irving, Texas and the hotel was again renamed the Lexington Hotel and City Square Sport Club.
Hotel management changed for a final time in 2003, and the property was renamed the Hilton Garden Inn.
Since then, the City Square Sports Club has been managed independently from the hotel.

4000 is the tallest tower in City Square, and has been noted on the List of tallest buildings in Phoenix, which lists 25 Skyscrapers in the city.
Businesses inside 4000 Tower include Arizona Drug Screening & Investigations, First Community Financial Corporation, and Parsons & Goltry Law Firm.
