LEGO Ideas Treehouse Press-Release

LEGO Treehouse blooming with sustainable bricks! Since the LEGO Group launched its first bricks made of plant-based polyethylene last year, the sustainable bricks have increasingly been included in new LEGO sets. The soon-to-be-released #21318 LEGO Ideas Treehouse contains the highest number of sustainable bricks ever in a LEGO set and is another important step to fulfill the LEGO Group’s sustainability ambitions. The LEGO Ideas Treehouse celebrates Kevin Feeser’s design for its endless creativity that its unique to the LEGO System in Play and its embodiment of the LEGO Group’s sustainable materials challenge. All 185 leaves and plants in the treehouse are made from plant-based plastic – the largest number of plant-based elements in a LEGO set so far. Below is the full press-release.

A gathering point for family and friends. A secret hideout. A fortress. A sleepover. LEGO fans can now immerse themselves in the intricately detailed #21318 LEGO Ideas Treehouse. A challenging build, the exclusive set, made up of more than 3,000 elements, is one of the largest LEGO IDEAS sets to date. The Treehouse is packed with play-inspiring features and comes with a landscape base and removable treetop to reveal three detailed cabins. A special feature of the set is that all 185 plants and leaves are made from sustainable materials sourced from sugarcane. This includes the treetop canopy, which has interchangeable sets of green summer leaf elements and yellow and brown fall leaf elements. 3,036 pieces, including 180+ botanical elements made from plant-based polyethylene plastic using sustainably sourced sugarcane. The set measures over 14” (37 cm) high, 10” (27 cm) wide and 9” (24 cm) deep. Recommended for age 16+.

Tim Brooks, Vice President, Environmental Responsibility, the LEGO Group, said: “When I first saw the model, I was blown away. Not only because it looks amazing, but also because it connects strongly to the very reason, we are investing so much time and effort in identifying new and sustainable materials, which is to preserve natural resources and fulfill our planet promise. It really is an important step in our ambitious target of making all LEGO elements from sustainable materials.”

During 2018, the LEGO Group began making botanical elements, including trees, leaves and bushes, from plant-based polyethylene using sustainably sourced sugarcane. Children and parents will not notice any difference in the quality, durability, or appearance of the new elements, because plant-based polyethylene has the same properties as conventional polyethylene. These elements represent the first milestone in the LEGO Group’s ambitious commitment to making products using sustainable materials by 2030.

The Treehouse is an example of how the LEGO Group uses co-creation to foster innovation, as the original idea was submitted through the LEGO Ideas platform, where LEGO fans can upload their creative builds. Users then have a chance to review and support the model and, given sufficient support, the build can end up as a certified LEGO set with the help of LEGO master designers. In this case, the model was submitted by fan designer Kevin Feeser from Nancy, France. Kevin’s motivation for creating a treehouse stems in particular from his passion for the great outdoors combined with pretty sophisticated LEGO building skills.

Kevin shares the following on the LEGO Ideas page: “Since my early childhood, I have been fascinated by construction and modeling. That’s why I was excited to receive new LEGO boxes for Christmas or birthday. I loved to construct them but I was more excited to use the new bricks for my own creations. Passionate by nature, wildlife, and wood constructions, I concretized this project about childhood dreams and travel. The idea emerged during an unusual weekend with friends in treehouses, such as Robinson Crusoé. It’s about an adventurous family that rebuilds their life after being lost. Using recovered materials, they adopted a tree as a new place to live.”

The LEGO Group is on a mission to make all LEGO bricks sustainably by 2030. For the LEGO Group, a sustainable material must have a reduced environmental footprint, be produced responsibly using renewable resources, and meet their high standards for safety, quality, and durability. High standards for sustainability, safety, quality and durability mean that there are no simple replacement materials on the market, and the LEGO Group is working with suppliers, research institutions, and other industries to develop new materials to be used in the LEGO bricks of the future. The LEGO Group has an ambition to find sustainable packaging alternatives by 2025 that are renewable, efficient, and recyclable.

All the trees, leaves and bushes and many of other elements in LEGO sets – more than 80 types – are now made from green polyethylene, which is made from ethanol produced from sustainably sourced sugarcane. The sugarcane is grown in Brazil, is sourced responsibly, and does not compromise food security. Polyethylene is just one of many materials used in LEGO elements, and the LEGO Group expects the materials of the future will be made from both plant-based and recycled sources. Customers can expect the same high quality of our plant-based elements. The elements do not biodegrade… because we want to make safe, functional and durable products that can be played with for generations.

Here is the designer-video for the set with LEGO designer Cesar Carvalhose Soares. He will show you the treehouse from many more angles, discuss the design process, and highlight many of the lovely little details.

The #21318 LEGO Ideas Treehouse model is available directly from LEGO retail stores and the Online LEGO Shop exclusively for LEGO VIP members beginning July 24, 2019, with general public availability beginning August 1, 2019. Prices are as follows: US $199.99 – CA $269.99 – DE €199.99 – UK £179.99 FR – €199.99 – DK 1799.0DKK. For more details, and to purchase the set, visit the LEGO Ideas section of the Online LEGO Shop.

LEGO Train Layout & Landscape Standards

LEGO train sets usually come with enough track pieces to make a simple loop, and may also include a small station for passengers and cargo. Other than these basic features offered by official LEGO train sets, LEGO fans are on their own when it comes to building train layouts. This is, of course, not a bad thing, as LEGO is all about creativity. However, because LEGO train layouts tend to be quite large and complex, it is best to establish some kind of a standard. Today, we will discuss systems LEGO fans adopted to standardize LEGO train layouts.

Having an agreed upon standard for train layouts is especially important when collaborating with other LEGO fans for large public displays. And it can also be a good idea if you are just building for your own pleasure. The available LEGO track elements, the geometry of the track pieces, and the size and shape of the trains all establish a certain scale. This scale can help you design other sections of the layout like roads, houses, commercial structures, vegetation, etc.

Another important aspect to think through is the management of electronic components. Modern LEGO trains run on batteries, but if you want to add lights and other electronics, you will need to have a system for neatly running wires through the layout. And, if you are using the old 9-volt train system you will have to think about the wires of the tracks as well.

The LEGO train system is usually referred to as ‘L-gauge’ among fans, in reference to traditional model railway scales. LEGO trains use a nominal gauge of 37.5mm, 5.5mm wider than O gauge, derived from a centerline gauge of 40mm (or five LEGO studs). The incompatibility of LEGO trains with traditional model railway scales makes it all the more important to establish a consistent standard, especially for collaborative projects.

The L-gauge.org information resource website was set up for exactly this reason. L-Gauge is the result of the collective knowledge, wisdom, and best practices from LEGO train fans from around the world. The goal of the project is to help support, promote, and educate fans and hobbyists interested in learning about and building LEGO model trains and layouts. Please note that the information is not official, but it is used by many LEGO User Groups and LEGO conventions around to world in order to ease collaboration among LEGO train fans.

Building a L-Gauge train layout involves many of the same factors of design and artistic flair as building a train layout in any of the traditional model train scales. The L-gauge.org website contains detailed information about LEGO track elements and geometry, track configurations reference, overview of train wheels, and more.

In addition to information on LEGO trains and tracks, there are also detailed guides for building MILS modules, which stands for “Modular Integrated Landscaping System”. The MILS standard allows multiple builders to build sections of train layouts and landscapes separately, and then bring them together as a cohesive display. We talked about this system a few years ago in the following article, which includes some educational videos on building MILS modules: LEGO Tutorials by Back Room Builder

The MILS standard was developed and documented by members of the HispaLUG/HispaBrick community for collaborative diorama displays. Among its key features is that it is simple and flexible and can be used with many different LEGO themes besides trains. MILS modules are primarily based on 32×32 baseplates. They are raised 1 brick (3 plates) above the baseplate reference level. This allows modules to interconnect with LEGO Technic bricks and pins, while also making the sections much stronger than regular LEGO baseplates. In addition, there is plenty of room to hide wires for electric components inside the modules.

The MILS standard is easy to understand, easy to implement, and can be expanded indefinitely. Even if you don’t collaborate with others for building large displays, it is an efficient system for your own layouts that can come very handy. As an example, if you ever need to relocate, you can take apart and move your entire display with relative ease. However, the system does require planning. For example, if you want to incorporate the LEGO Modular Buildings, you would build them on a MILS base rather than on the baseplate provided with the set, or build them a MILS to Modular Adapter Base (as pictured below).

If you like to work with LEGO trains, build LEGO City displays, or any other large dioramas, I highly recommend studying the MILS standard. It is based on decades of knowledge by experienced LEGO fans. At least it will give you some key pointers to think about when designing your own project, and thus potentially having to build and rebuild repeatedly down the road (which may or may not be a bad thing). So, visit L-gauge.org and look around the site. I think you will find it valuable.

What do you think? Do you have a LEGO train or other large LEGO layout? Are you using any systemized way for setting the up, expanding them, and possibly move them? Have you used the MILS standard before? Did you ever participate in a larger project that used the MILS standard? Feel free to share and discuss in the comment section below!
