Making good use of a neighboring rooftop

This is the 8th & Madison “M” Building.  The management and residents obviously invest in their rooftop space, certainly in comparison to Skyline.

Note the activities:

• a jogger on the left,
• table tennis and spectators at center,
• a dog walker and
• two gardeners at right.

Note their rooftop furnishings:

• table and chairs for eight near the jogger at the left,
• the embedded plant display at lower left and again at upper right;
• the 14 tubs for gardening at lower right;
• those chairs at top right which are shaded in the afternoon.

Why, given eight years in which to do it, has Skyline failed to invest in the 26th floor Observation Deck (except when it is time to take pictures for marketing purposes)?
