One question that's often raised by homeowners doing a porch addition is, "What shape should the columns be?". Well, it depends on the style of your house. In our opinion, on a Dutch Colonial round columns work best. Something about their round form in combination with the unique geometry of the gambrel roof form fits. Just like with many design decisions, there is not always a clear answer, and our opinion is based on years of testing both round and square forms and finding that round columns just feel right.
