Chester County residential projects generally range from $9,500 to $20,000 for a paver patio or garden installation, $72,000 to $160,000 for an in-ground pool with surrounding hardscape, and $5,500 to $15,000 for a full planting design and seasonal program. Properties along the Main Line corridor in Devon, Malvern, Paoli, and Berwyn often include mature tree canopy and established foundation plantings that require selective removal and careful root zone protection before new work begins, which adds cost. Chester County townships are active permit authorities, and the Chester County Planning Commission also reviews projects in historic preservation overlay zones, which can extend permitting timelines by four to eight weeks. Your free consultation includes a site assessment and a plain-English breakdown of which permits and timeline factors apply to your property.
