“ Over the past weekend my family members have been exclaiming how spectacular the cottage is — as have I, of course. There were tears of joy last evening. To say thank you is wholly inadequate. Your design, your selection of finishes, your insistence on using Steve to build the cottage — just several of the reasons for our deep appreciation.”

About a new cottage on Georgian Bay

“Seventeen years ago, we had bought a home on a beautiful 2-acre property. But now, it was time to update the house with a modern kitchen and a great room in an open concept style. We retained the services of Harry Lay Architect … we now have a house that takes full advantage of the surroundings and provides a lovely kitchen and great room: the acme of comfort and style in all seasons.”
