How to Build the Lego Collection of Your Dreams

You dream of a basement-wide cityscape, but you also have to pay rent. We asked Lego Master and brickfluencer Stacey Roy how to do it.

I don’t remember when my family first acquired our first Lego bricks. Like awakening from a fever dream, I regained consciousness in the past few years and realized we now have a whole room dedicated to Lego, with thousands of bricks organized by color in a chest-high shelving unit (and a big bin of mixed pieces on the floor).

Most enthusiasts can empathize and have a similar experience. None more so than Stacey Roy, the “brickfluencer” who won last year’s season of Lego Masters. The Fox show is a competition between diverse pairs of Lego enthusiasts as they compete against each other in a series of, frankly, insane themed building challenges. Last season, actor Chris Pratt guest-hosted a Jurassic Park–themed episode where the teams had to include fireworks and explosions in their dinosaur builds. Roy and her partner, Nick Della Mora, won in a finale that challenged them to incorporate their very first Lego set into their master build.

The competition removes one major constraint: Each team can pick whatever pieces they need and however many from the Brick Pit, an incredible wall with millions of bricks and specialty bricks for each challenge. If you’re just starting out, accumulating enough pieces to build anything can seem like the first step on a path to insolvency. Yes, sometimes you’re just broke. (I promised my husband the Colosseum for Christmas, FML.) But we all have to start somewhere. We asked Roy for her tips on how to get started building a Lego collection.

Start With a Theme

Most of us get into Lego the same way—we find a set we really want and go from there. “I felt the urge to get back into Lego a few years ago, in the most insane way possible,” Roy says. “I bought the Millennium Falcon ($850). It’s an amazing set and I highly recommend it.”

Lego started making licensing deals as far back as 1999, adding iconic properties like Star Wars and Marvel to its roster. If you’re into Star Wars, starting out by collecting each of those sets is probably the best way to build up a collection of specialty pieces to reuse. The most recognizably unique pieces are probably the minifigures, but with a little imagination, other pieces can be repurposed as well. Roy points out that the Lego pink frog on a bonsai tree looks exactly like a cherry blossom when you take a step back.

Once you’ve started with a theme, Roy recommends the modular building sets, which come with a large number of particularly useful building pieces. For example, the Boutique Hotel ($230) has Victorian-style wrought-iron railings that, when you look closer, are actually skeleton arms. “Lego is incredibly imaginative when it comes to reusing pieces,” Roy says. Pay attention to what you want to build, and you will learn which pieces and building styles you prefer.

Finding Specific Pieces

If there’s a specific piece you need to have to complete a build, Lego’s online Pick a Brick—where you can find pieces by keyword, piece number, color, and set—is the natural first place to start. But it’s not your only resource.

My family is subscribed to the Lego Insiders program, which, depending on how many Lego bricks you buy, is worth it. You get points for purchases and a heads-up on Lego sales. My 8-year-old also enjoys the Lego Life kids’ magazine. It’s important to note here that you don’t get points for purchases made outside of official Lego stores or Lego.com, which means that purchases made at Legoland and at Lego-certified or affiliated stores won’t count toward your totals.

Roy recommends visiting your local Lego store in person. “Because every Lego store is different and offers different things, I make it a priority to visit every store in person when I travel,” she says.

Looking at resale sites can be a great way to acquire a lot of bricks cheaply and quickly. Roy’s favorite place (and mine) to start shopping is Facebook Marketplace. “They often have great deals on people selling bins of unorganized and random Lego sets,” she says. As a parent, I’ve also found that Facebook is a hub of parents trying to get rid of Lego sets their children have outgrown. I find many bins of used Lego on my local Buy Nothing group or on Facebook Marketplace for local pickup.

However, if you’re scouring eBay, Facebook Marketplace, or Craigslist for Lego, I would budget in time to talk to sellers to verify the condition of the bricks and, you know, make sure the seller is a real person. It also takes time to wash and sort used, sticky bricks. Lego reselling—especially for rare or discontinued sets—can be a big business, so if you’re shocked at certain prices, just remember that Lego sets differentiate in value depending on whether they’re new, sealed, unsealed, or used.

In my early days as a Lego shopper, I thought I would acquire off-brand Lego brick sets and my children would not notice the difference. I can’t believe how wrong I was. Not only does the material usually differ perceptibly, but the fit is sometimes just off. That can be a big problem if you’re building something extremely large and don’t want it to topple over. “Lego bricks have a magical X-factor that really helps them fit together,” Roy says. “You can really mess up a build. It’s really important that the build be structurally sound.” 

Finding Ideas

Now that you have a ton of bricks, are you stuck for ideas? My 6-year-old loves The Big Book of Amazing Lego Creations With Bricks You Already Have, which includes detailed pictures and instructions simple enough for a first-grader to follow. For more advanced builders, we also love The Art of the Brick, by famous Lego artist Nathan Sawaya. 

Rebuild or riff on the sets you already have, or try building some of the items you see in your everyday life, like guitars, apples, or eggshell cartons. “Just start small and enjoy the process,” Roy says. You can move up to working Lego go-karts or playable mini-golf courses from there.
