4.12. Security Measures
Shutters
Security should be provided by laminated glass or internal lattice grilles. Where possible, laminated glass is preferable. External roller shutters should not be used as they contribute to a sense of vacancy on the high street and have a negative effect on the night-time economy by reducing active frontage.
Electronic devices
Devices such as sirens and lights linked to burglar alarms should be concealed or located sensitively to reduce the appearance of clutter and to avoid damaging the historic fabric. This also applies to electrical wires, satellite dishes and other antennae, including those used for flats and other rooms above the ground floor. To preserve the texture of the brick or render it is advisable to avoid fixings on heritage assets which can lead to structural damage. Electronic devices should only be used where the need for them has been demonstrated and alternative ways to reduce threat and risk have been considered. Depending on the type and location of the device, planning permission is likely to be required.
A poor example of electrical wiring and electronic devices cluttering a shopfront, London.
Security shutters should not be used externally, but instead behind internal lattice grilles, or preferably, laminated glass
