Simple hand-drawn scamps are ‘roughs’ that creatives use when working on project concepts and ideas. It’s a sketch of an idea and represents how the concept works and mostly does not get seen by the customer.
When I started out as a designer the scamp was usually presented to the client over lunch on a paper napkin! This would often result in us getting the nod that we were thinking along the same lines. It was simple but very effective.
The ‘scamp’ gets stakeholders on board early on. It saves time and expense in producing highly rendered visuals and CAD drawings which come later. The example here was a 5-minute sketch from nearly 20 years ago for a high street retail project, which in itself paved the way for a design concept which largely remains the same to this day.
