Refreshing the '70s: Makeover mantras

Remodeling projects often involve knocking down walls to gain the open floor plan everyone wants today. "But they can feel like barns — too tall and cold," said architect Mark Kawell. He suggests changing ceiling heights and using pilasters, built-ins and ambient lighting to visually define spaces.

The 1970s were the heyday of split-level and split-entry homes, said architect Jeremiah Battles of Acacia Architects and co-author of a book on remodeling splits. "They were a reaction to the dark, full basements in ramblers," he said. "Splits gave you a more light-filled lower level that was only half underground."

The home style typically has a tiny foyer. If a front-entry expansion isn't feasible, Battles suggests updating the flooring, the staircase and front door to transform the appearance of the foyer. "Replace carpeted stairs with wood and add a transom window over the door to bring in more light," he said.

Consider tearing out rustic ceiling timbers and popcorn ceilings. Replace carpet with hard-surface floors and laminate countertops with stone. Replace windows and doors for improved energy efficiency and a fresh contemporary look.
