Normally when parking space is precious in the driveway a sliding automatic gate is the answer.
A sliding electric gate will open by sliding to one side of the entrance. It does not take up any additional space that may be required to get a second car into the driveway.
However if there is not enough room to slide the gate to the side then there is a problem. In the past the only option in this case was to have a folding Automatic Gates Dublin Ireland (or bi-folding ) gate installed.
