General Jim’s Corner Post Office Modular Building Block Set – 4,030 Pieces

Bring timeless city charm and architectural elegance to your collection with General Jim’s Corner Post Office, a detailed three-story modular building block set with over 4,000 pieces. Inspired by the grand European post offices of the late 19th and early 20th centuries, this set captures the golden era of communication—when letters, parcels, and telegrams connected communities before the rise of modern technology.

Post offices were once the beating heart of every city street, not only serving as hubs for sending and receiving mail but also as social landmarks. Many were constructed with ornate architecture, crowned by clock towers, and built to symbolize reliability and civic pride. This set pays tribute to that history with stunning Art Nouveau–style details, including arched windows, decorative spires, and a central clock above the grand entrance.

On the ground floor, you’ll find a fully functioning post office complete with a service counter, cash register, waiting area, and mail sorting room. A red delivery truck, mailbox, park bench, and classic street lamp bring the bustling streetscape to life.

The second floor transforms into an art school, furnished with easels, paints, and decorative details designed to spark creativity. Above it, the third floor hosts a pottery studio with authentic pottery wheels and finished projects proudly displayed, offering endless storytelling opportunities.

Each level lifts away for easy access to the interior, while external features like the domed roof, balcony, and clock spire create a commanding presence on any city block. Both a creative challenge and a rewarding display piece, the Corner Post Office stands as a must-have for collectors, builders, and architecture enthusiasts alike.

LOVED this build!

My first off-brand build and I was not disappointed. Challenging build at times, but not unexpected by reading other off-brand reviews. Parts come in bags that are sorted better than LEGOs usually are. This build is much more detailed than LEGO ever gets - probably cost prohibitive for them - LOVE the amount of exterior detail. No instructions for the lights, so use your imagination for placement. Have already purchased other kits sold by General Jim. Questions answered promptly - great customer service!
