Secure Package Delivery for 2 Family House

[Andrew Mikhael]

I am planning a side by side duplex property and want to make sure we have a convenient and secure place to get packages delivered. From what I've found, the options for package lockers can only be USPS access or Private (FedEx/UPS etc) access but not both. I'm thinking to use Salsbury Recessed Mounted 4C Horizontal Mailbox - 10 Door High Unit (37 1/2 Inches) - Single Column - 1 MB3 Door / 1 PL5 - Front Loading - USPS Access. Has anyone used a better option for securing packages from both USPS and private deliveries?
