House Plus-Plus instructions

Construct a Plus-Plus House with these free 3D step-by-step instructions and interactive build guide.

This 89-block building model features walls, a roof, and architectural details that create a recognizable little house in three dimensions. The higher piece count supports a more substantial display piece than mini builds.

Classified as hard difficulty with an estimated build time of around 15 minutes, the guide walks you through the base and walls first, then the roof and exterior accents. The interactive 3D viewer helps you keep walls square as the structure grows.

Start Building online or download the printable PDF for offline building. Sorting all 89 blocks by color before you begin makes the longer project much smoother.

The finished Plus-Plus House is perfect for town scenes, architectural play, or a rewarding weekend build. Check wall corners carefully for a sturdy, display-ready home.
