A wall here, a door there. A sunroom stretching out from the back of the house, just so. Recessed lighting in the kitchen. A custom-designed fireplace in the living room. And outside, a deck, a curving walkway, and a strategic planting of a few yews and Japanese maples. If playing with such details of home, interior and landscape design sounds like a good time to you, you’re not alone. Mac users with an urge to design have plenty of programs, both beginning and advanced, from which to choose.
