New build plots in Cambridge and the surrounding Cambridgeshire villages are frequently handed over at completion with compacted soil or a temporary stone layer rather than a finished surface. The first step is a site assessment covering plot dimensions, drainage falls, soil conditions, and the garage apron detail, flat Fenland plots and clay-heavy Cambridge ground both create standing water risks that affect sub-base specification.
Planning rules apply before any surface is chosen. An impermeable front garden surface over five square metres requires compliance with Building Regulations for surface water drainage, or a planning application. A permeable surface, resin bound aggregate, porous asphalt, or gravel, avoids that requirement in most cases. Cambridge City Council planning rules apply to front garden surfacing, so the check happens at survey stage rather than after the surface is laid.
The installation sequence covers excavation to formation level, compacted MOT Type 1 sub-base, drainage channel or soakaway connection, edging and kerbing, and the chosen surface course. Minimum width for two cars is typically 4.8 metres; single-car width is 2.4 to 3 metres. The quote covers each stage as a separate line item so sizing, drainage, and surface costs are visible before any work is committed to.
