Since its opening in 2017, LEGO® House has seen the annual release of exclusive sets in their shop, typically focused on the history of the LEGO Group. This tradition continues in 2026 with the launch of set 40507 I ♥ Billund, a tribute to the town where the company has been based since its inception in 1932. This set does a couple of things differently, so join us as we break down the many locations and Easter eggs the set contains!
We were given this product early by The LEGO Group; the author's opinions are their own.

- Pieces: 1404

Decorated elements
Though the set does not include any recoloured elements, it introduces three exclusive decorated elements.
Notably, the labelled 1 x 8 tiles found in prior LEGO House exclusive sets have been replaced with a pair of more visually interesting tiles:
- 1x Tile 2 x 4 with Groove with 'Billund' Street Sign print in White (6595923 | 87079)
- 1x Tile 2 x 6 with 'LEGO® House Home of the Brick™' print in White (6595951 | 69729)
While the decorated tiles are most welcome, the focal point for builders is likely to be the new baby body with printed pants. The pants decoration extends around the full figure, including the sides and back. These represent new areas for a decoration to be applied to such a figure.
- 1x Baby / Toddler Body with Fixed Arms and Yellow Hands with Pants print in Red (6600801 | 25128)
The available scales of the classic red and blue minifigure continue to expand!
Rare elements
A handful of rare elements find usage throughout the set, as we've come to expect from LEGO House Exclusives.
Making their second appearance in a set, we find:
- 6x Plate 3 x 3 in Bright Yellow/ Yellow (6588872 | 11212)
- 1x Dish 4 x 4 Inverted with Open Stud [Radar] in Bright Yellow/ Yellow (6636769 | 35394)

- 1x Bracket 1 x 1 - 1 x 1 Inverted in Bright Orange/ Orange (6554439 | 36840)
Four of the elements in the set are only available in two prior sets, appearing for a third time here:

Building experience
LEGOLAND submodel
A microscale version of the LEGO Train and a small section of Miniland – showing the famous Nyhavn canal in Copenhagen – are located directly behind the park entrance.
LEGO® Campus, Ole Kirk’s House, and LEGO System House
At this stage, focus shifts to the facilities and infrastructure of the LEGO Group.
In the front, we find the LEGO® Idea House, which comprises two internally connected buildings: the former home of the company's founder, Ole Kirk Christiansen, and the LEGO System House.
Ole Kirk's House is known locally as the “Lion House,” owing to the distinctive lion statues lining the entrance, depicted here with grey clips. It has previously been represented in LEGO form for the exclusive LEGO® Inside Tour, both in 2009 as well as a miniaturized version in 2025, and so this microscale version is the first publicly available version – if you can make it to Billund, that is.
LEGO System House was built in 1958 as the company's international headquarters. A local nickname is "Knophuset" (The Stud House), because the exterior walls are covered in a grid of LEGO studs, but this detail could not be depicted at this scale! LEGO System House has also been the subject of a LEGO Inside Tour set, which we covered in detail at the time as it contained the first ever 3D-printed LEGO element: LEGO System House and the 3D-printed drafting machine.
The interior of LEGO Idea House features a handful of hidden Easter eggs that only the builder will get to see. A rendition of the classic LEGO wooden duck is found inside of Ole Kirk’s house, and brick-built depictions of I ♥ Billund's designers, Maria Anna Jędryszek and Stuart Harris are located in LEGO System House.
Behind LEGO Idea House, we find the LEGO® Campus, which serves as the current headquarters for the LEGO Group. The building was previously depicted in 4000038 LEGO Campus, an employee-exclusive set launched to coincide with the completion of the building in 2022. Once again, the appearance here marks the first time the building appears in a set available to the public.
An airplane flying above the campus is a subtle reference to the Billund Lufthavn (airport), which originated as a private airfield for the company, established by Ole Kirk's son and successor Godfred Kirk Christiansen.
The parkland surrounding LEGO Campus features a variety of decorative features, some of which are captured in the model. An oversized minifigure that sits in front of the building has been rendered by the baby minifigure, along with one of the crooked lampposts found on the campus.
The model also features one of the oversized duck statues, which the builder is encouraged to customize during the construction process. This is a curious, somewhat confusing feature that I have not seen in a set previously.
To the right of the campus, we find a small depiction of the LEGO Kornmarken factory, though the likeness is rather lacking as it only represents a fragment of the building. A delivery truck is located along the front of the building, while a AGV is visible inside via a window.
Once again, LEGO Kornmarken is a building that has been the subject of its own employee-only set, 4000005 KOM Moulding, meaning all four buildings represented on this section of the model are available commercially for the first time.
The focal point of the display is a depiction of LEGO House, established by Godfred's son and successor Kjeld Kirk Kristiansen in 2017. This is the third depiction of the building in a set, following 2014’s 4000010 LEGO House and 2017’s 21037 LEGO House. The proportions of the building are somewhat exaggerated when compared to these prior sets, but complement the other structures in this model.
LEGO® House
Removing the top floor of LEGO House reveals a miniature version of the central atrium. Inside we find renditions of the Tree of Creativity and brick moulding machine, both of which have been subjects of previous LEGO House exclusives.
The recent Bracket 1 x 2 with 1 x 2 Vertical Studs (4585) is used to create the Nordic cross on the Dannebrog, connected to the rest of the assembly via Plate 1 x 1 x 2/3 Half Round with Side Stud (3386).
Completed model
Once the model is complete you can appreciate one more feature: the winding line of orange pieces in the base represents the Billund Playline, a walking route that takes in the LEGO sights of Billund.
This model feels like something that should have never escaped the LEGO offices, in the best way possible. Constructing the set, it feels as though it was designed with a dual audience of both LEGO employees and fans, owing to the inclusion of the LEGO Group's offices and facilities, which have historically appeared only in employee gifts.
At the same time, one cannot escape the slight irony of a set marketed as a tribute from the LEGO Group to the town of Billund containing only structures that the company owns. I personally believe this would have been an excellent opportunity to include some of Billund's other notable locales, such as the Teddy Bear Art Museum, the actual buildings of Billund Lufthavn, or Grene Kirke.
Despite this, I have little doubt that the set will prove immensely popular with tourists traveling to Billund. It successfully captures landmarks of the town that the target audience of LEGO fans will instantly recognize, resulting in a charming memento of one's memories of the town.
