Hamish Robertson and Mary Fitzgerald didn’t want to move, but it looked inevitable. As much as the couple, who work as a software engineer and a server respectively, loved their neighborhood in Almonte, Ontario, their circa-1890 Victorian home was bursting at the seams as their two small, busy kids grew. But then, it occurred to them that their lot was large, and the footprint of the house took up just a fraction of the property; the conditions were ideal for an expansion. Maybe they could have it all—a larger home, the same address.
