Build LEGO models of the Eiffel Tower and the Empire State Building, compare designs, measure heights, and learn basic architecture using step by step instructions.



Step-by-step guide to build the Eiffel Tower and the Empire State Building — LEGO style
Step 1
Gather all the materials and put them on a clear workspace.
Step 2
Place the reference pictures where you can see them easily.
Step 3
Decide to build the Eiffel Tower first.
Step 4
Choose a scale for your models (for example 1 brick = 1 meter) and write it on your paper.
Step 5
Sketch a simple side-view outline of the Eiffel Tower on the paper using your chosen scale.
Step 6
Sort LEGO bricks by size and color for the Eiffel Tower.
Step 7
Build the Eiffel Tower base and legs following your sketch.
Step 8
Add the upper sections and spire to finish the Eiffel Tower model.
Step 9
Measure the height of your Eiffel Tower model with the ruler and write the number on your paper.
Step 10
Sketch a simple side-view outline of the Empire State Building on the same paper using the same scale.
Step 11
Sort LEGO bricks by size and color for the Empire State Building.
Step 12
Build the Empire State Building model focusing on its stacked tiers and spire using your sketch.
Step 13
Measure the height of your Empire State Building model and write the number on your paper.
Step 14
Write two design differences and one similarity between your two LEGO buildings on your paper.
Step 15
Share photos and a short description of your finished LEGO Eiffel Tower and Empire State Building 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 we use if we don't have LEGO bricks for this Eiffel Tower and Empire State Building project?
If you don't have LEGO bricks, substitute Duplo or Mega Bloks (sorted by size and color as in the instructions) or cut colored cardboard blocks to follow your sketch and build the Eiffel Tower base and legs and the Empire State stacked tiers.
My Eiffel Tower keeps wobbling — what should I check or fix?
If the tower wobbles or tiers won't align with your sketch, reinforce the base by adding wider plates and interlocking bricks, recheck the chosen scale you wrote on paper, and measure with the ruler as you add upper sections and the spire.
How can I adapt this activity for different age groups?
For ages 4–6 use larger Duplo pieces and a pre-drawn simple outline to build the base and legs, for ages 7–10 have them sketch side-views, sort bricks, and measure heights with the ruler, and for 11+ require a precise scale, detailed stacked tiers and spire work, and written design comparisons.
How can we make this LEGO architecture activity more creative or advanced?
Enhance the project by mounting both models on a labeled baseplate that shows the chosen scale, adding battery LED lights to the spires, writing the measured heights and the two design differences plus similarity on your paper, and then photographing the display for DIY.org.

Facts about architecture and model building for kids
🧪 LEGO bricks are made from ABS plastic, which makes them strong, durable, and great for stacking tall towers.
📐 The Eiffel Tower is repainted roughly every 7 years to protect it from rust, using about 60 tonnes of paint each time.
🗼 The Eiffel Tower was built for the 1889 Exposition Universelle and stands about 324 m tall including its antennas.
🏙️ The Empire State Building was completed in 1931, has 102 floors, and reaches 1,454 ft (443 m) to its tip (1,250 ft / 381 m to the roof).
🧱 The modern LEGO brick design was patented in 1958 — and LEGO studs are spaced 8 mm apart, handy for measuring model scale!
