The creative energy spills like sunlight from the house at 7 Hills Road in Loudonville. And early-spring anticipation is budding in every room. Designers bustle here and there, paintbrushes in hand, coaxing possibility to fruition, their laughter bouncing off the freshly painted walls. The metamorphosis unfolding at this home is all in preparation for Vanguard-Albany Symphony’s annual Designer Showhouse fundraiser, to benefit the Albany Symphony Orchestra. Each year for the past 29 years, the volunteer organization has sought out a home to redecorate and has invited the area’s most talented designers and decorative painters to join them in the effort. Those chosen have a little less than eight weeks to completely transform the space assigned to them. Once the home is picture-perfect, the public is invited in for tours. This year’s Showhouse began as a 2000-square-foot, 1950s ranch. The home’s original owner lived there until about two years ago.
