They are usually meticulously created by experts using technical software to create precise diagrams for officials and councillors to peruse.
But a drawing submitted by a Lowestoft cafe to its local council as part of a licensing application has been raising eyebrows for taking a different approach.
The graphic provided by The Salty Crow to support its bid to add outdoor seating to its premises has been likened to a child's drawing.
The image was created on an iPhone and submitted to East Suffolk Council, along with other supporting information by vegan nutritionist Emma McKay, who opened the cafe in August 2022.
It shows the proposed positioning of two tables and four chairs outside the vegan cafe's London Road North premises.
The 'shop' and 'road' are clearly marked, while the 4m width of the pavement is also given - though not necessarily to scale.
The image does not fully depict the application: the business actually wants to put four tables and 12 chairs on the pavement.

However, the image's shortcomings did not appear to sway the council. Ms Mackay said the application had been approved.
A local government insider said: "These documents are usually expensively produced by professionals.
"It does make you wonder why businesses bother if you can just knock something up on an iPhone."
Ms McKay declined to comment on the application drawing.
