Access ramps can help you enter and exit the home more easily. It's not just mobility impaired folks that need ramps - mothers with pushchairs or prams can also appreciate being able to push their offspring into the home without having to carry heavy loads or offload outside.
Access ramps can be built permanently or temporarily, out of wood or steel and non-slip surfaces can be applied afterwards.
The gradient of a ramp should be 1 foot of ramp for every inch of height needed - but you can also add a landing to give the person a rest.
Different types of professionals can install ramps - carpenters, builders, handymen, and more. Make sure they're familiar with the Australian Standards for ramps and have the appropriate insurance.
