Bungalows are one- or one-and-a-half-story dwellings with sloping roofs and unenclosed rafters in the eaves, and they generally have a dormer window (or an attic vent made to appear like one) over the main section of the house. This contributes to the distinctive aesthetic that most people identify with the California bungalow. The typical California bungalow has three bedrooms and two bathrooms, but some can be found with four rooms and even five. The California bungalow is often described as easy on the eye because of its simple lines and natural materials used in its construction. Bungalows were originally built by Americans for American families who wanted simple homes that did not cost a lot of money to build. They were usually built out of wood, with some brick or stone added for warmth during cold seasons or when electricity was available at night. Over time, builders began using more durable materials when constructing bungalows, such as aluminum, vinyl, and tile. Some modern bungalows still contain many original elements from their wooden counterparts including exposed beams, sliding glass doors, and patio decks. As with many other types of homes, the California bungalow was also used as an affordable option for homeowners who wanted something smaller than a mansion but didn't want to live in an apartment complex. Many famous celebrities own California bungalows due to their size, style, and price range.
