Late spring on the road out of Niles toward Buchanan, everything green is running at maximum and the shade is finally worth something. Custom Outdoor Living Inc. builds yards for that season — mowing and edging, bed shaping, mulch, plantings sized for the room they will actually have. A property here can hold old hardwood, a slope and a patch of sand all at once, so the work starts with reading the ground. The pleasure is standing back at day's end and seeing a yard that fits its house. In Niles that is no small thing; the houses have opinions.
