Look at the whole approach
Consider the path, slope, surface, lighting, gate, steps, threshold and the amount of level space in front of the door. Difficulties often come from a combination rather than one dramatic obstacle.
Handrails can be very effective
A secure rail in the right place may be enough when balance is the main issue. It should be positioned for the person using it and fixed into something strong enough to take their weight.
Ramps need more space than people expect
A comfortable gradient can require quite a long run, especially where there is a substantial height difference. Turns and level resting areas may also be needed, so measure the available space before assuming a ramp will fit.
Thresholds matter too
Even a low door threshold can be difficult for a wheelchair or walking frame. There are ways to reduce or bridge thresholds, but weatherproofing and drainage still need to be considered.
Sometimes another door is easier
The front entrance is not automatically the best one to adapt. A side or rear door may provide a flatter approach or more room for a ramp, depending on the house and garden.
