Blind LEGO Review: LEGO Harry Potter Privet Drive – Aunt Marge’s Visit (76451)

The best 4 Privet Drive yet
Alina and I are huge LEGO fans, and we absolutely love the Harry Potter universe. So, when we heard about the new LEGO Harry Potter Privet Drive set from 2025, we knew we had to build it. We’ve listened to the audiobooks many, many times, enjoyed all the movies, and are super excited for the upcoming TV show on HBO Max. This past June, we even traveled to London to see Harry Potter and the Cursed Child in the West End and visited Warner Bros. Studios, where the films were shot. So, we decided to add another corner of Harry Potter’s world to our own LEGO collection – set number 76451.
Although we’ve only been LEGO builders for a little over a year now, we’ve already collected more than 122 sets since August 2024. Harry Potter sits right alongside modular buildings as our main obsession, and this set felt like the perfect addition to our growing magical brick-built world.
The LEGO Harry Potter Privet Drive: Aunt Marge’s Visit set recreates one of the most memorable scenes from The Prisoner of Azkaban, when Aunt Marge insults Harry’s parents and pays a hefty price by inflating like a balloon and floating away in the sky. With 639 pieces, this two-story house captures the essence of 4 Privet Drive, Little Whinging, Surrey, the most ordinary house in Britain hiding the most extraordinary boy wizard.

The building experience
As someone who is totally blind, I challenged myself to put together the main structure piece by piece, just as I’ve done with larger sets. Alina guided me through the instruction steps, describing each piece and section, while she later decorated the interiors and added all the smaller details. This teamwork reminded us of when we built the Cozy House, since this model also opens up like a dollhouse, making the whole experience even more whimsical.
The box
The box art for the set also deserves mention: it shows the scene in which Aunt Marge floats comically into the sky. Harry, wand in hand, is caught in the moment, and the other Dursleys look horrified. The branding sits in LEGO’s classic blue Harry Potter theme box, instantly telling you this is part of the Wizarding World line.
The exterior of the house
The finished house is wonderfully faithful to its on-screen counterpart. It stands over 16 centimeters tall, 31 wide, and 12 cm deep. The walls are a warm, buttery yellowish tan, mimicking the neat suburban brickwork of Privet Drive. The roof is a deep reddish brown, with ridges you can feel as you run your fingers across. On one side of the house is a sunroom with large, smooth, clear windows, giving it a polished, shiny feel under your fingertips. The build splits in two, in the middle, on the side of the house.

The interior
Once you swing open the house, the magic begins. On the ground floor, after you go through a tiny hallway, you’ll find the living room with a brown sofa, a fireplace in the same color with a clock plus some other items on it, a TV, a family portrait (minus Harry, of course), all forming a cozy scene despite the Dursleys’ coldness toward Harry. Next to it is the kitchen, where a rectangular brown dining table takes center stage. Harry Potter fans will instantly recognize this as the spot where Aunt Petunia’s pudding met disaster in The Chamber of Secrets, as the designers decided to include it in this set. Hidden cleverly at the back of the ground floor is a tiny cupboard under the stairs – Harry’s first bedroom – accessible through a little secret door.

Connecting the floors is a well-built staircase, one of my favorite parts to assemble, with a steady rhythm to the build. Upstairs, the story continues. Harry’s bedroom is small, with only a white bed, a Gryffindor wall sign, and a Bertie Bott’s Every Flavour Beans on the floor. Beside it is Dudley’s room. Dudley’s space has a bright red bedspread, a computer on a desk, and even a large TV. To drive home his spoiled nature, LEGO added a huge stash of candy on the floor. Each room has its own atmosphere, captured through clever color choices and furniture.
Minifigures and accessories
The minifigures add even more enjoyment. Here’s a brief description for each:
- Harry Potter – dressed in a dark blue open jacket over a plaid shirt
- Vernon Dursley is shown with grey hair and a tan sweater
- Petunia Dursley is wearing a white blouse with a necklace and a dark red skirt
- Dudley Dursley is wearing a bright blue sweater with a napkin tucked around the neckline
- Marge Dursley – the inflated version of the character – shown floating away, has a light brown hairstyle and a dark brown, printed suit with a patterned vest
- Marge Dursley – the standard minifigure version – is also included in the set and wears the same, nevertheless pre-bursting, outfit
- Ripper, Marge’s bulldog, is a light brown color, white on the head, with a blue collar around his neck.
The set also includes a small side build of the Privet Drive sign next to a black lamppost, with a black fence base underneath, adding an authentic touch of suburban street life. This is also where Hedwig decided to perch.
Final thoughts
From the cupboard under the stairs to the hilarious inflated Aunt Marge, everything about it ties back to the Harry Potter universe we know and love.
Whether you’re a longtime fan of the books and movies, or like us, you’ve also visited 4 Privet Drive at Warner Bros. Studios in Leavesden, this set connects you instantly back to those magical moments.
So, if you’re a Harry Potter fan and a LEGO enthusiast, don’t miss this one. It’s hands down the best LEGO representation of 4 Privet Drive yet, full of color, humor, and nostalgia.
