This week’s #buildingdoodle sketch is by Frank Porthouse, director at Project Design Studio, and depicts an expansion to a coffee house in Woburn, Bedfordshire. He says: “The sketch shows the design concept for an orangery to be built in the walled garden to the rear of a grade II-listed Georgian building. The additional space will provide garden-linked dining space for the Woburn Coffee House.”
