VIDEO DEMONSTRATION

Description

Operating undetected from Muggle's knowledge, Diagon Alley is a bustling high street catering for wizards and witches with wares to make potions or stock on up spell crafting necessities like cauldrons, brooms and wands.

Consisting of 4 "doll-house" like buildings, Diagon Alley will thrill and delight Harry Potter fans - but the true magic of this LEGO set is realised when it is coupled with the Light My Bricks light kit that truly brings this enchanting set to life!

With the ability to arrange and connect the separate buildings anyway you like without compromising the lights, the Light My Bricks light kit gives you the flexibility to display Diagon Alley however you like, and at the same time, enhance all the unique features this set has to offer.

Using film frames as reference, the design was continually iterated and innovated to ensure the lighting and atmosphere was as true to the film as possible.

With 74 individual lights, including internal and external lighting, the Light My Bricks will put a spell on your Diagon Alley and make it a true centrepiece to marvel at.

Important Note

We recommend lighting this kit by a USB Power Bank or USB Power Adaptor (to connect to a mains outlet), which is NOT included in this kit. If you do not have a USB Power Bank, you can purchase them from our Powering section.

So far so good

Only part way through, adding lights to already built Diagon Alley, looks great so far and pleasantly suprised how bright the lights actually are

Wonderful

The installation process was probably the most finicky and even frustrating from all the sets I've done so far, but the end result is wonderful.

Part of the frustration came from taking the levels apart. Diagon Alley is a not a modular set, so taking the floors apart was a bit messy. Also, the buildings' insides are quite cramped, so a number of leds were really finicky to install or connect. Finally, I felt some of the design choices could have been better. In multiple cases I routed the cables differently. For example with the gargoyle, where the headpiece just would stay put with the cable going through the pin. There's a perfectly fine alternative routing between to bricks of the nearby wall instead.

Anyway, I'm very happy with the result as always!

A magical customer service experience

These sets are obviously extremely detailed and take your Lego set to the next level. They are absolutely unmissable for the show stopping sets and change the entire vibe of the display. I’ve bought a couple of sets before and never had an issue. I did have one faulty part in this kit, however, I was blown away by the care and attention from customer service, particularly Rachel. She was immediately responsive, delightful to deal with and promptly sent out the replacement part so I could continue building. 10/10 would recommend these sets and this company - it’s absolutely worth it to me!
