1. A rooftop package delivery receptacle for unmanned aerial vehicles comprising:
a. a fixed curb frame comprising longitudinal frame members and transverse frame members defining a roof aperture;
b. a pair of hinge joints mounted directly upon the longitudinal frame members of the frame, the hinge joints being adapted to pivotably receive portions of an expandable contractible platform therewithin;
c. electromechanical rotational means configured for enabling the platform to rotate between a normally closed position substantially parallel to the frame, midway to a substantially horizontal position for package delivery, and upward to an inwardly slanted position for package collection and to any position therebetween;
d. the expandable contractible platform further comprising a plurality of coplanar slidably mounted panels;
e. sliding means configured for enabling the panels to longitudinally and transversely expand outwards and contract inwards;
f. electromechanical expansion and contraction means configured for expanding the platform outwards for package delivery and contracting the platform inwards for package collection and platform closure; and
g. an upper and lower accordion shaped shutter portion removably attached between the frame and the platform adapted to enclose gaps therebetween.
