LEGO Modular Buildings are designed to fit together to create a cohesive street scene, and while individual set heights vary, they are built on a consistent base size.
Based on how they fit together in a display, a standard LEGO Modular Building is roughly 10 inches (about 25-26 cm) wide/long and about 10 inches (about 25-26 cm) deep at its base. Their height can vary significantly but is often around 11 inches (29 cm) or taller.
According to information from October 5, 2020, when four standard size LEGO Modular Buildings are placed side-by-side in a specific layout:
- The combined height is 11 inches (29 cm).
- The combined length is 40 inches (102 cm).
- The depth of this specific layout is 5 inches (13 cm).
The reference notes that this layout depth is "half the depth" of four standard buildings. This implies that a standard building's full depth is closer to double that amount, around 10 inches (26 cm), which aligns with the standard 32x32 stud baseplate size typically used for these sets (approximately 10x10 inches or 25.6x25.6 cm).
From the layout dimensions, we can infer the approximate size of a single standard building:
| Dimension | Layout of Four Buildings | Implied Standard Single Building Size |
|---|---|---|
| Height | 11 inches (29 cm) | Varies by set, often around 11"+ |
| Length/Width | 40 inches (102 cm) | ~10 inches (25.5 cm) |
| Depth | 5 inches (13 cm) | ~10 inches (26 cm) (Standard Depth) |
To display four of these buildings in a row as described, you would need a shelf that is a bit over a meter (100 cm or ~40 inches) long.
In summary:
- LEGO Modular Buildings typically occupy a footprint of approximately 10x10 inches (25.6x25.6 cm).
- Their height is variable, but a common reference height is around 11 inches (29 cm).
- They are designed to connect seamlessly along their ~10-inch sides to form a street.
This consistent sizing allows builders to easily connect different sets from the series side-by-side, creating a dynamic and expanding LEGO city street.
