"You look to an old house not only for inspiration," said Heide, "but for the rules you need to follow." Here are some of the ways Heide and Crull honored the period of the home in their remodeling and addition:

• Built oak cabinets over exposed radiators that match the home's original wood trim.

• Matched the new wood floors in the addition to the refinished original wood floors for continuity.

• Recycled some of the original windows for use in other parts of the house.

• Replaced missing molding.

• Installed antique lighting or designed their own.

• Added vintage-style stenciling in the kitchen, dining room and living room by Amy Miller of Trimbelle River Studio in Wisconsin.

• Matched the trim on the opening to the kitchen addition to the original oak trim openings to the living room and dining room.

• Replicated 1920s kitchen cabinets.

• Chose a vintage English porcelain kitchen sink.

• Restored the dining room oak built-in buffet and added missing upper cabinets.
