A modular landing port for use on a top of a building structure. The modular landing port includes a base portion. One or more landing module extend from the base portion. The one or more landing modules have a first end provide proximate the base portion and a second end spaced from the base portion. Each of the one or more landing modules have a landing/take-off zone proximate the second end and at least one loading/unloading zone proximate the first end. The landing/take-off zone and the at least one loading/unloading zone are configured to receive a vertical take-off and landing aircraft.

A first construction module for a modular landing platform is for vertical landing aircraft. The module includes a module body with a resting wall placed on a supporting surface. A landing wall opposite to the resting wall is adapted be contacted by the aircraft during the landing step. First and second interconnecting walls are opposite to each other and interposed between the resting wall and the landing wall. First and second coupling portions protrude laterally outwards from the first interconnecting wall, the first and second coupling portions being of a different type and mutually spaced apart. Third and fourth coupling portions protrude laterally outwards from the second interconnecting wall, and are of a different type and spaced apart. The third and fourth coupling portions of the first module are adapted to couple respectively with the first and second coupling portions of a second module identical to the first module.

A vertical escape structure comprises an escape housing disposed in a vertical orientation and mounted to a ground to maintain structural integrity in the vertical orientation against external flooding. The escape housing includes an interior which is sealed against water entry from exterior flooding and at least one of a staircase, a ladder, an elevator, or a lift disposed in the interior of the escape housing. The vertical escape structure further comprises a connecting walkway to connect the escape housing to a building. The escape housing has a smaller horizontal footprint than the building. The walkway is severable from the building by force without damaging the escape housing to cause water entry from the exterior flooding.
