Last year I called Craftsman millwork and design for a little challenge, built a kitchenette in an octagonal gazebo which is not always heated on winter. They came to take there template of the counter and explain me the issue of having a kitchen in a non-heated area. So they built it with exterior grade material and it is the second winter happening right now and everything is still perfect with no splitting or chipping. Thanks to Craftsman millwork team!!!
