In HappiCities we hope to use Drones to create a last mile logistics service to delivery food from restaurants, your amazon packages, daily newspapers etc.
For this, we need to re-design building that supports this feature. For example: The residential buildings must have a QR coded Balcony to uniquely identify the household and a place to drop the package securely in the Balcony.
The city design must account for the drone flight path and the commercial places like restaurants should have a dedicated area where the drone will land and the parcel be loaded.
That's why we must accept the fact that Technologists and Urban planners must come together to engineer urban solutions for 21st Century.
