Simon Helberg, one of the five central characters in the ensemble comedy "The Big Bang Theory," has listed his Los Angeles home at $849,000.

The restored two-story Craftsman, built in 1910, is entered through a deep-set front porch with a swing. Period features include leaded windows, built-in cabinetry and wood floors and trim. The main house contains a fireplace, a den, five bedrooms and two bathrooms. Guest space above the detached garage has a kitchenette and a bathroom. An additional office with a bathroom sits next to the garage.

The comic actor, 30, plays fashion-challenged and self-deluded "ladies man" Howard Wolowitz on the sitcom, which started in 2007. He starred in "Derek and Simon: The Show" (2007).

Elisa Gil-Osorio of Nourmand & Associates in Beverly Hills is the listing agent.
