How to Make a LEGO Modular Building

What you need
Adult supervision required, baseplate (optional), colouring materials, lego bricks, notebook, pencil

Step 1

Gather all your LEGO bricks and place them on a clear table or the floor so you can see everything.

Step 2

Open your notebook and draw a quick sketch of one creation you want to build.

Step 3

Choose the main bricks and colours you will use for your design.

Step 4

Place a strong base on your baseplate or make a wide foundation with bricks to start building on.

Step 5

Build the main body of your creation by stacking and connecting bricks to match your sketch.

Step 6

Add at least one moving part like a door wheel or hinge to your model.

Step 7

Move the part you added several times to see if it works smoothly.

Step 8

Find any wobbly spots and strengthen them by adding extra bricks or supports.

Step 9

Try one experimental change such as swapping a piece or rebalancing weight to improve stability or looks.

Step 10

Test the whole model by doing the action it should do (roll it open it or gently bump it) to check performance.

Step 11

Write in your notebook what design choices you made and what improvements you tried.

Step 12

Share a photo and a short description of your finished creation and what you learned on DIY.org.

Final steps

You're almost there! Complete all the steps, bring your creation to life, post it, and conquer the challenge!

Help!?

What can I use instead of a LEGO baseplate or hinge if I don't have them?

If you don't have a baseplate, use a flat piece of cardboard or a hardcover book under 'Place a strong base on your baseplate or make a wide foundation', and if you lack a hinge or wheel for 'Add at least one moving part', improvise with a paper fastener, bottle cap axle, or taped cardboard flap attached to bricks.

My moving part sticks and the model feels wobbly—how do I fix that?

Follow the step 'Find any wobbly spots and strengthen them' by widening the foundation with overlapping plates, add extra bricks or supports under the moving part from the 'Build the main body' step, and adjust weight distribution as in 'Try one experimental change' so the hinge or wheel can move smoothly.

How can I adapt this LEGO activity for different age groups?

For toddlers use larger Duplo-like bricks, a very simple sketch and adult help for 'Place a strong base' and 'Add at least one moving part', for school-age kids keep the full steps and encourage 'Try one experimental change', and for older kids add complex mechanisms, technical pins or a small motor and detailed notes in the notebook.

What are some creative ways to extend or personalize the finished LEGO build?

After 'Test the whole model' and writing 'what design choices you made', personalize it by adding stickers or custom paint, adding extra moving parts or a motor for new actions, and expand the backstory in your notebook before you 'Share a photo and a short description on DIY.org.'

Facts about engineering and design for kids

📝 Designers, engineers, and kids use LEGO to prototype ideas quickly — it’s a fast way to test stability and improve moving mechanisms.

🚗 LEGO produces so many tiny tires and wheels that the company has jokingly been called one of the biggest tire-makers in the world.

🔧 LEGO Technic parts (gears, axles, beams) let builders create real mechanical functions like steering, gear trains, and suspension.

🧪 Most LEGO bricks are made from ABS plastic, which gives them strong, durable snaps and smooth surfaces for moving parts.

🧱 The modern LEGO stud-and-tube clutch system was patented in 1958 — bricks from then still click with today’s pieces!

How do I run a LEGO design-and-build challenge where my child designs, tests moving parts, and documents improvements?

Start by setting a clear challenge (vehicle, animal, machine) and let your child sketch ideas. Gather bricks and build a simple prototype, focusing on modular sections so parts can be changed. Test moving parts and stability—spin wheels, push joints—and note failures. Encourage iteration: tweak connections, swap pieces, reinforce weak areas. Document each version with quick photos or short notes about changes and what worked. Celebrate creative choices.

What materials do I need to set up a LEGO design-and-build activity at home?

Basic LEGO bricks and plates, plus baseplates for building stability. Include axles, gears, wheels, hinges, and Technic pieces for moving parts. A brick separator, small containers for sorting, and a notebook or voice memo app to record design choices. Camera or phone for photos, tape or labels to mark versions, and Duplo bricks for younger builders. Optional: instruction booklets for inspiration and craft supplies for decoration.

What ages is a LEGO design-and-build activity suitable for?

This activity scales well: use Duplo for ages 2–4 with close supervision because of small parts. Ages 5–7 enjoy guided building and simple moving elements with adult help. Ages 8–12 can design deliberate mechanisms, experiment with stability and document iterations independently. Teens and older kids can tackle engineering challenges, advanced Technic pieces, and systematic testing. Always supervise children under 3 due to choking hazards and adapt complexity to the child’s skills.

What are the benefits of having my child design, build, test, and document with LEGO?

Designing and building with LEGO boosts spatial reasoning, problem-solving, and planning skills. Testing moving parts teaches basic physics and engineering concepts, while iterating builds resilience and creative thinking. Fine-motor control and hand-eye coordination improve, and documenting choices strengthens communication and reflection. It's a low-cost STEAM activity that encourages collaboration when kids build together and can increase confidence as children see their designs evolve throug
