Why Adults Became Central to LEGO Growth

Introduction

Adult LEGO sets have become one of LEGO’s most important new growth engines because they expand the company beyond the traditional child-and-parent toy cycle. The key shift is not simply that adults also buy LEGO. It is that LEGO has turned building into a premium hobby, a display object, a collectible, a gift category and a stress-relief ritual. That gives the company more routes to demand when children’s toy spending softens, birth rates fall or play habits move towards screens.

In antifragility terms, adult sets make LEGO less dependent on one audience and one use case. A Botanical orchid, a Technic supercar, a Star Wars collector model and an Architecture landmark all use the same brick system, but they reach different motivations: home décor, fandom, engineering interest, nostalgia, collecting and gifting. LEGO’s own 2025 results said demand was high among both children and adults, while its largest-ever portfolio included LEGO Icons and LEGO Botanicals among the most popular themes.

How display models changed the audience

For much of LEGO’s history, the adult audience existed, but it was not always addressed as openly as a mainstream consumer segment. That changed as LEGO began treating adults as builders in their own right rather than as parents buying for children. Its current “Adults Welcome” category describes complex sets “designed specifically for adults”, spanning sport, vehicles, art, architecture, space, film and pop culture, and frames the activity as a way to “unplug, unbox and unwind”. [LEGO]lego.comOpen source on lego.com.

The product design is central. Many adult sets are not primarily playsets. They are objects to finish, display and talk about. That changes what counts as value. A child’s set often competes on play features, minifigures and repeat scenarios. An adult display set can compete on shelf presence, building difficulty, fidelity to a real object, nostalgia, brand collaboration or how well it fits a room. LEGO Botanicals is the clearest example: flowers and plants are not only toys but durable gift and décor objects, positioned by LEGO around occasions and display rather than traditional play. [LEGO]lego.comOpen source on lego.com.

That opened a route into customers who might not have seen themselves as “LEGO people”. LEGO said in its 2024 results that the Botanical Collection attracted new builders and was especially popular around gifting occasions; in 2025, Botanicals remained one of the most popular themes and was described as bringing new, younger fans into LEGO play for the first time. [LEGO]lego.comOpen source on lego.com.

The attraction is not only the finished object. LEGO’s adult marketing increasingly sells the process: quiet concentration, a screen-light activity, and the satisfaction of making something physical. Its “Find Your Flow” material explicitly links adult building with slowing down, relaxation and mindfulness, while its adult-set pages point buyers towards home décor, cars, movie icons and pop-culture display pieces.

This is a different growth mechanism from chasing a children’s fad. A successful adult display set can sit across several buying occasions at once: a birthday present, a housewarming object, a fandom purchase, a couple’s build, a desk ornament, a self-care purchase or a collector’s item. That gives LEGO more surface area for demand without leaving the brick system.

Why adult hobbies add resilience

The adult segment matters because the wider toy market is under pressure from forces LEGO cannot fully control: falling birth rates, squeezed household budgets, screen competition and volatile children’s trends. Circana reported that global toy sales across 12 major markets declined slightly in 2024, but building sets grew 14% and became the top toy supercategory for both sales and growth. The same report explicitly pointed to “kidult” buyers as a stabilising force. [Circana]circana.comOpen source on circana.com.

Europe shows why this matters strategically. Circana valued the market for teens and adults aged 12 and over at €4.5 billion in 2023, representing 28.5% of total toy sales, and linked the opportunity to ageing populations and fewer children under 12. [Circana]circana.comToys Market in Europe – Fandom, Nostalgia Fuel €4.5 bnToys Market in Europe – Fandom, Nostalgia Fuel €4.5 bn In the UK, Circana later reported that the 12+ “kidult” market accounted for £1 in every £3 spent on toys in the year to June 2025. [Circana]circana.comU.K Toy Market Grows as Christmas ApproachesU.K Toy Market Grows as Christmas Approaches

For LEGO, this does not replace children as the core mission. The company still speaks about reaching children and “builders of tomorrow”. But adult sets add a second demand rhythm. Parents may reduce toy spending in a downturn, but adults may still buy a smaller Botanical set as a gift, a licensed collector may wait for a major Star Wars release, and hobbyists may continue buying parts or display models over time. These patterns do not move identically with children’s toy fads.

Adult demand also supports a broader price ladder. The same brand can sell relatively accessible flowers, mid-priced cars and buildings, and very large collector models. Reuters reported that LEGO’s 2024 revenue rose 13% to DKK 74.3 billion while the wider toy market declined, and noted CEO Niels Christiansen’s emphasis on Botanicals attracting more teenage girls and women. [Reuters]reuters.comLego sales rise as bricks click with more shoppersLego sales rise as bricks click with more shoppers LEGO’s own 2024 announcement credited record results to a large, diverse portfolio for builders of all ages and interests. [LEGO]lego.comOpen source on lego.com.

That diversity is the antifragile part. Volatility in one area can reveal where demand is moving rather than simply damaging the company. If children’s play shifts towards digital worlds, LEGO can test gaming-linked physical sets. If home décor gifting grows, Botanicals can expand. If motorsport interest rises, Formula 1 partnerships can feed Technic and display sets. If nostalgia cycles revive old franchises, Icons and licensed collector lines can absorb that energy into the same brick system.

Premium sets work because they reuse LEGO’s strongest system

The adult growth engine is powerful because it does not require LEGO to become a different company. LEGO can serve new interests while still relying on its familiar strengths: modular bricks, instructions, clutch power, parts reuse, displayable models and a global fan community.

This is why adult sets fit the company’s post-crisis discipline. The 2000s turnaround taught LEGO not to chase every adjacent business at the expense of the brick. Adult sets are different: they extend the brick system into new cultural contexts. A botanical bouquet, a Formula 1 car, a NASA spacecraft, a modular building and a film prop are all new expressions of the same underlying product grammar.

The company has also built channels for adult feedback and participation. In 2019 LEGO acquired BrickLink, describing it as the world’s largest online adult LEGO fan community and marketplace, with more than one million members and over 10,000 stores in 70 countries. LEGO said the acquisition would strengthen ties with adult fans and deepen collaboration with a “passionate, committed and endlessly creative” community. [LEGO]lego.comOpen source on lego.com.

That matters because adult hobbyists do more than buy boxed sets. They review, modify, collect, resell, display, photograph and design. LEGO Ideas gives fans a formal route to submit potential sets, vote for other members’ ideas and reach a 10,000-vote threshold for review. [LEGO]lego.comBrick LinkBrick Link BrickLink’s Designer Program similarly creates a route for fan-designed models aimed at experienced builders. [bricklink.com]bricklink.comOpen source on bricklink.com.

This fan infrastructure turns adult demand into information. LEGO can see which licences, scales, building styles, display formats and nostalgic references generate real enthusiasm before committing to broader production. That does not remove risk, but it lowers the cost of learning. A toy company that can learn from adult collectors, fan designers and secondary-market behaviour has more feedback loops than one relying only on seasonal children’s retail sales.

The strongest example is Botanicals, not the biggest spaceship

The giant collector model is the most visible symbol of adult LEGO, but Botanicals may be the more revealing growth case. A huge licensed set proves that some adults will spend heavily. Botanicals proves something broader: LEGO can enter a non-obvious adult category and make the brick feel natural there.

The Botanical Collection reframed LEGO as a substitute for flowers, houseplants and craft décor. LEGO’s own 2024 press material said the collection, introduced in 2021, had quickly become one of its most popular product ranges, combining creativity and relaxation and appealing especially to adults seeking mindful, stress-relieving activities. [LEGO]lego.comFan Engagement and ProgramsFan Engagement and Programs

The commercial logic is unusually flexible. A Botanical set can be bought by someone who enjoys building, someone who likes plants, someone looking for a low-maintenance gift, someone decorating a shelf, or someone who wants a shared activity. It is less dependent on one film release, one character or one childhood memory. That makes it a useful example of antifragile diversification: LEGO converted a cultural trend towards home styling, craft and mindful hobbies into a new category that still uses LEGO parts.

Retail and consumer commentary has picked up the same pattern. Which? placed Botanicals at the top of its 2025 popular LEGO themes list, describing the sets as decorative, low-maintenance and linked to mindfulness; it also identified Icons as a major adult-and-collector range built around advanced techniques and display. [Which?]which.co.ukthe most popular lego sets and themes a EPDT0y2RU6Tthe most popular lego sets and themes a EPDT0y2RU6T

The important distinction is that Botanicals widened the audience rather than merely monetising existing adult fans. A Star Wars Ultimate Collector Series model mainly speaks to people already comfortable with LEGO, Star Wars or both. A bouquet or orchid can reach adults who would never buy a spaceship, castle or minifigure-heavy playset. That is why the theme matters so much for growth: it creates new entrances into the LEGO system.

Where premium adult sets create new risks

Adult sets make LEGO more resilient, but they do not make it risk-free. The same choices that create growth can also create fragility if pushed too far.

The first risk is affordability. Premium adult sets can command high prices because they offer long build times, display value, licences and collectability. But high prices can also narrow the audience and create frustration among fans who feel the hobby is becoming less accessible. Community commentary around adult LEGO often focuses on expensive display sets, reduced play features and shelf-space competition with cheaper, younger-facing products. [thebrickblogger.com]thebrickblogger.comThe Problem with LEGO Sets for AdultsThe Problem with LEGO Sets for Adults

The second risk is over-dependence on licences and nostalgia. Adult buyers often respond strongly to Star Wars, Harry Potter, Formula 1, video games, classic cars and other recognisable properties. These licences can make sets easier to market, but they add royalty costs, contract exposure and cultural risk. They also concentrate attention around familiar franchises, which can crowd out original themes if the balance is wrong. LEGO’s 2025 results show the company mixing both sides: City, Botanicals and Icons sat alongside Star Wars and Technic among popular themes. [LEGO]lego.comGrow Your Creativity With Four New LEGO® Botanicals SetsGrow Your Creativity With Four New LEGO® Botanicals Sets

The third risk is complexity. Adult sets often have more pieces, more specialised design expectations and more demanding quality standards. LEGO’s portfolio reached 840 products in 2024 and more than 860 products in 2025, with around half new in 2025. [LEGO]lego.comOpen source on lego.com. A broad adult portfolio gives LEGO more bets, but it also increases the challenge of forecasting demand, managing parts, allocating shelf space and avoiding fatigue.

The fourth risk is sustainability. Adult collectors often keep sets, resell them or display them for years, which can support circular value. But premium display sets are still physical plastic products, and LEGO remains under pressure to reduce fossil-based material use. The company reported that renewable and recycled content in materials purchased for bricks rose to an estimated 52% in 2025, up from 33% in 2024, while revenue had grown 29% since 2022. [LEGO]lego.comthe LEGO Group Annual Report 2024the LEGO Group Annual Report 2024 That progress matters because adult growth will be harder to defend if bigger, display-led consumption appears environmentally careless.

The final risk is relationship management with serious fans. Adult builders are a strength because they generate ideas, content, feedback and secondary-market activity. But they are also demanding. They notice price changes, colour mismatches, missing prints, licence compromises and perceived corporate control of fan spaces. LEGO’s BrickLink acquisition gave it closer access to adult fans, but it also raised the stakes: a community that feels heard can become a source of innovation, while a community that feels exploited can become a reputational liability.

Why this growth engine is antifragile rather than merely opportunistic

Adult LEGO sets are not just another product line. They change the shape of LEGO’s demand. The company can now grow through children’s play, family gifting, adult relaxation, pop-culture collecting, home décor, fan design, nostalgia and premium display. Those routes overlap, but they are not identical. That makes the business less brittle.

The adult strategy also turns cultural shifts into options. Ageing populations, lower birth rates and screen-heavy childhoods are threats to a conventional toy company. For LEGO, they are also signals: adults still want tactile hobbies, fandom objects, offline rituals and displayable achievements. LEGO does not have to abandon children to benefit from that. It can keep the brick as the shared system while varying the audience and occasion.

The most important lesson is implementation discipline. Adult sets work because LEGO did not simply slap an “18+” label on ordinary toys. It changed packaging, subject matter, display value, retail language, fan engagement and occasion-based marketing while keeping compatibility with the core brick system. That is why the adult segment belongs in an antifragility analysis: it shows LEGO using uncertainty in the toy market to discover a broader, more resilient version of itself.
