If you know anything about high-end appliances, you probably know that built-in refrigeration starts and end with Sub-Zero. (If you didn’t, now you do.) Viking Range, Thermador, Gaggenau, and Northland also command respect but not enough to dethrone Sub-Zero. (The folks at GE would like to think its Monogram brand is a player; it’s not!) Anyway, Liebherr is a German brand that happens to do built-in refrigerators fairly well. The HCB 1560 and HC 1540 are the newest introductions and are the company’s first fully integrated 30-inch single-door refrigerator-freezer units. Each features BioFresh technology that helps food stay fresher longer, both measure 24 inches deep so they sit flush with cabinets, and both can be concealed behind a custom panel. Perfect for condo or apartment living, the HC 1540 model does not require a water connection for the ice maker thanks to an internal removable water tank. The HC 1540 costs $4,869 and the HCB 1560 costs $5,479. www.liebherr-appliances.com.
