New York City has very few "perfect blocks" so those with a lot of admirable architecture should be cherished.

29th Street between the west side of Sixth Avenue and the west side of Park Avenue is one such stretch.

It has two historically important churches, several impressive hotels and three imposing residential skyscrapers.

The newest building is the Gansevoort Park Hotel on the southeast corner of Park Avenue, a "sister" hotel to the extremely popular Gansevoort Hotel in the Meatpacking District. Designed by Stephen B. Jacobs, its energetic form and facades magnetize this area, which already abounds in interesting projects and is just a few blocks north of the lovely Madison Square Park and its Shake Shack and Flatiron Building.

The just across the street and a little to the east on the same block is Twenty9th Park Madison, a 34-story residential condominium tower at 39 East 29th Street that was completed in 2009.

It is one block east of the Sky House, the very handsome, red-brick, 55-story residential condominium tower at 11 West 29th Street, shown at the left, that was completed in 2008 and is immediately adjacent to the very picturesque and attractive Little Church around the Corner. The tower was developed by The Clarett Group and designed by FXFowle.

The Sky House and the church are directly across the street from the mid-block 48-story Madison Belvedere rental apartment tower at 10 West 29th Street that was developed in 1999 by Rose Associates Inc. and designed by Schuman Lichtenstein, Claman + Efron.

With its handsome, gilded top, which is illuminated at night, this 396-apartment tower became a major new component of the Manhattan skyline when it was erected in 1999.

The beige brick-building has a concierge, a 24-hour doorman, a garage, a canopied entrance, many three-sided balconies, a fitness center, sidewalk landscaping and a two-story polished red granite base with a rusticated limestone entrance surround. The building has an ATM, dry cleaning, and shoe repair and a washer/dryer unit is on every floor.

On the northwest corner at Fifth Avenue is the famous and lovely Marble Collegiate Church that was designed in Romanesque Revival-style in 1851 by Samuel A. Warner and further down the block is a cooperative apartment building at 17 West 29th Street that was built as a hotel and converted to the Gilsey House co-operative apartment building in 1980, and the quite attractive Hotel Breslin reopened in 2009 as the Ace Hotel at 16 West 29th Street. The former was designed by Stephen Decatur Hatch and the latter by Clinton & Russell.

The street's newest skyscraper is also the boldest. Named Eventi, it is a mixed-use, 53-story tower at 835 Sixth Avenue that was designed with many amenities and a large and impressive mid-block plaza by Perkins Eastman Architects for the J. D. Carlisle Construction Corporation. The tower has three different fenestration patterns.
