This week’s sketch of the week is “structural concept sketches for a perspective office development” by John Roycroft, civil and structural engineering director at BDP.

Roycroft says: “Conversational sketching is still a skill that is important for an engineer. Recently I had the pleasure of looking at a Marc Brunel diary and simple but effective sketches jump out and describe complex engineering principles in a timeless and effective diagrammatic language that a page of words would struggle to convey.”
