Ever since humans started erecting buildings we have geared ourselves towards protection from the elements. Whether it’s wind, rain or immense heat, buildings all over the world are designed to give their users a few minutes (or hours) of relaxation before getting back out in the big, wide world. Let’s face it though, we need to keep our buildings protected from a lot more than this and one of the biggest things we face in the modern day and age is protecting ourselves against crime. The Crime Prevention Through Environmental Design (CPTED) is a set of principles that is geared towards this exactly, preventing crime through building design.
