LEGO House Calculator

Estimate bricks, spares, weight, and cost for a LEGO-style model house.

How to Use

  1. Enter outside dimensions, floors, openings, spare percentage, and an optional per-brick price. Doors and windows are subtracted from wall area.

Assumptions and Limits

This independent estimator uses a common brick volume and packing allowance. Real designs need varied parts, bonds, and structural support.

Method

Net wall area × estimated wall thickness is converted to a common-brick volume, then roof and spare allowances are added.

Examples

Example

A 30 × 20 × 15 cm single-floor model with one door and four windows.
