The greenhouse (or glasshouse) of a car comprises the windshield, rear and side windows, the pillars separating them (designated A-pillar, B-pillar and so on, starting from the car's front), and the car's roof.[1][2]

The shape and position of the greenhouse have a defining influence on the looks of the car and are a prime factor in differentiating between body styles such as saloon/sedan, coupé, estate/wagon and hatchback. A greenhouse with noticeably inward side slopes is also referred to as the tumblehome.

In the 2000s and 2010s, greenhouses have become narrower because of design trends and crash regulations.

Some manufacturers incorporate trademark design features in the greenhouse that are present across several model series, one example being the BMW Hofmeister kink.
