Question: Which building contains more square feet, 50 Hudson Yards or 15 Penn Plaza?

<P0-S0> 15 Penn Plaza, also known as the Vornado Tower, is a proposed 68-story tower in the Midtown Manhattan section of New York City planned by Vornado Realty Trust. <P0-S1>  The Hiller Group is the designer. <P0-S2>  It would have 430 units and 2,050,000 square feet (190,451 m²) of floor space. <P0-S3>  Despite only having 68 floors, it would be just 10 m shorter than the Empire State Building, which has 102 floors. <SEP> <P1-S0>  The planned building is to be located to the north of 30 Hudson Yards, and on the east side of the Hudson Park and Boulevard, adjacent to 55 Hudson Yards. <P1-S1>  It will total 2.9 million square feet of commercial space. <P1-S2>  At the SW corner of 34th Street and 10th Avenue, it will replace the drive-thru McDonald's that had long-occupied the space. <P1-S3> 50 Hudson Yards is a building being planned as part of the Hudson Yards Redevelopment Project in Hell's Kitchen, Manhattan. <SEP> <P2-S0>  As usual there is a curtain of solid masonry inside. <P2-S1>  They Would then be encountered by the cross wall. <P2-S2>  On the south-west the outer wall or enceinte is entered by a rude gateway of a single pointed arch about eight feet high and five feet broad. <P2-S3>  In the south-east angle is a rude temple of Bhairavnath and a few houses with the remains of Man y more. <P2-S4>  It leads out to the path down to Girvi, a village in the plains below and it probably formed the communication with Phaltan. <P2-S5>  The gate lies about 150 yards east of the edge of the plateau, which there terminates in an almost unbroken vertical precipice of several hundred feet in height and receding in a north-easterly direction. <P2-S6>  This road winds down the face of the range for some five hundred feet till it hits the shoulder of a spur which it then follows to the base. <P2-S7>  [Elphinstone in Pendhari and Maratha War Papers, 245.] <P2-S8>  There are some remains of sepoys' houses, and, near the turret, a small stone wheel said to belong to a gun. <P2-S9>  The fort is believed to have been built by Shivaji to resist the Moghals whose attacks he must have dreaded from the plain below. <P2-S10>  Facing nearly north, about fifty yards from the north-east angle, is a gateway with a couple of curtains in solid masonry. <P2-S11>  Hence apparently the reason for strengthening the walls of the enceinte on this side. <P2-S12>  There is a gateway of a pointed arch with the top fallen in and twenty odd steps leading up to it and ten more cut out of the rock, and winding up past the inside curtain on to the top. <P2-S13>  About ten yards to the east of this turret is a new looking building which was the headquarters or sadar. <P2-S14>  The rest is massive and well mortared and still fairly preserved. <SEP> <P3-S0> 55 Hudson Yards (also known as One Hudson Yards or One Hudson Boulevard) is a future tower just outside the Hudson Yards Redevelopment Project. <P3-S1>  Located in Chelsea, Manhattan, it will add a combined 4000000 sqft of space to the Hudson Yards project, along with 50 Hudson Yards, even though the two buildings will be located outside of the redevelopment site itself.
