Framing with green oak is a bit of a Bentley because the raw material is quite expensive and the process of cutting and raising the frame is labour-intensive. Cost depends on the quantity and quality of the raw material and the complexity of the structure but expect to pay from £5000 for an open entrance porch and up to £15000 for an enclosed porch with a canopy. Don’t forget: my price is for a start-to-finish project: project preparation, foundation, wall and roof frame, roof deck and roof covering- and all finish detailing. This is an excellent value for the commitment you will receive from me, the quality of the product and the impact it will have on your home.
