Zero lot line homes are growing in popularity. A popular plan recesses the front door, with an entry courtyard for guests. Dimensional bluestone pads, only 3 feet in width, give more planting room on either side of this walkway. Divided by black Mexican rocks, the 50-foot-long path looks shorter than it is. Making a right-angle jog, it connects the door to the front sidewalk and accommodates an eye-catching water feature.
