About LEGO Building Set
LEGO Building Set (set #511) is a small, compact build with 27 pieces from the Duplo theme, released in 1969. The Duplo line features larger bricks designed for toddlers and preschoolers aged 1-5. Designed for young children aged 1+, the larger Duplo bricks are easy to handle and safe for small hands. This set dates from the 1960s, when LEGO established its universal brick system and opened the first Legoland park.
Set Highlights
- Oversized Duplo bricks — safe for children aged 1+, no small-parts risk.
- Compatible with all standard LEGO sets — bricks extend naturally into other sets you own.
- Play-focused build with interactive elements designed for 1+ builders.
- Vintage 1969 release — increasingly rare in complete, unplayed condition.
Who Is This Set For?
Parent & Child Building Activity
Duplo bricks are sized for small hands. Building together is the intended experience — simple steps and large pieces make it accessible for children aged 1+.

First LEGO Gift
A popular first-LEGO choice for young children — safe (no small parts), durable, and engaging enough to grow with the child.
Build Tips
Build together with your child — the visual steps are designed for parent-guided assembly.
After the guided build, encourage free rebuilding: Duplo bricks are designed to come apart easily and be reconfigured.
Store pieces in the original box or a divided container to keep this set separate from others.
