Interior designer Theresa Casey lives for large-scale projects. So when she and her husband, graphic designer Robert Gray, began a house hunt, her goal was “to buy a box and make it our own.” A 1930s brick Rosedale home with a forgettable interior was the ideal big, messy job. Among its dysfunctions: a cumbersome wall divided the main floor down the middle, and Moroccan arches made rooms heavy and funereal. The sole, tiny bathroom was at the top of the stairs. After the space was gutted, Casey sourced all-new decor and had much of it custom made. She explored a period design, mixing traditional elements with 1930s modernism. The master bath now has smoky, Old World glamour, with black glass and Negro Marquina marble, cherrywood accents and vintage brass faucets. The petite kitchen is modelled after the galley in a cabin on a luxury ocean liner, with Statuario marble and unlacquered brass. Casey brought in vintage hardware and custom cherry doors for all the entranceways. The dining room’s grillwork is salvaged from the Eaton’s College Park building (now the Carlu), another dramatic art deco touch.
