The Centre for Protection of National Infrastructure (CPNI) challenged Capita Lovejoy to research and develop a document that could communicate the topic of counter-terrorism security, particularly the risks posed by vehicle-borne threats, to the public realm design professional in an innovative manner that would both inform and inspire. CPNI’s aim is to maintain appropriate security measures within our built environment without compromising the ability of designers to create beautiful places for people.There are many factors influencing the design of our public realm and it is critical that landscape architects are well informed about relevant counter-terrorist security issues. It is important for the profession to encourage designers to consider the integration of physical security measures at the outset of the design process. This will ensure that our landscapes are not blighted by inappropriate or ill-considered responses but can continue to be inclusive, accessible and inspirational.Capita Lovejoy was responsible for all aspects of the project from original research to final graphic production which was carried out in very close collaboration with CPNI and their consultees. The document is set out in a simple clear structure of three parts; context, design response and finally appendices with further information and reference.The simplicity and clarity of the final document has been a mark of the success with which it has been received by government bodies, institutions and design professionals. The guide is published on the CPNI website, has featured on the BBC’s ‘Culture Show’ and has been presented at the GLA as part of the recent security conference.The subject matter is a relatively new phenomenon for landscape architects but is of increasing significance for all. The project has shed light on what is a new agenda within public realm design and it has demonstrated how landscape architects have an important role to play, working alongside government bodies, at the forefront of emerging issues in our environment.
