This is a great video from New England's NECN:

A little context:

One year ago, the Lee family was unhappy with their home.... They decided to take their old house down to the ground and build a modular home on the land....

The Lees ordered their modular home from a Pennsylvania company. They went modular not because of money, but because of time. The house was assembled like a puzzle - piece by piece.

Each box was about 85% complete on the inside when it was put together....

Modular was clearly the way to go.
