We at P-plan have extensive experience in assessing the utilization of the areas set aside for parking purposes. Often, there is talk of assessments around existing areas, where «retrofit» parking solutions are to be installed.
When assessing capacity in the design phase, our experience is that developers can save around 40-50% of volume use, measured against comparable traditional parking. This saving in volume use can be used to increase salable area, or to meet other requirements or needs that are necessary for the project as a whole to meet planning and building requirements.
