A multistorey car park (British and Singapore English) or parking garage (American English), also called a multistory, parking building, parking structure, parkade (mainly Canadian), parking ramp, parking deck or indoor parking, is a building designed for car, motorcycle & bicycle parking and where there are a number of floors or levels on which parking takes place. It is essentially an indoor, stacked car park. The first known multistory facility was built in London in 1901, and the first underground parking was built in Barcelona in 1904. (See History, below.) The term multistory is almost never used in the US, since parking structures are almost all multiple levels. Parking structures may be heated if they are enclosed. Design of parking structures can add considerable cost for planning new developments, and can be mandated by cities in new building parking requirements. Some cities such as London have abolished previously enacted minimum parking requirements. Minimum parking requirements are a hallmark of zoning and planning codes for municipalities (States don't prescribe parking requirements, while counties and cities can) in the USA.

The location had space for 100 vehicles over seven floors, totaling 19,000 square feet. The same company opened a second location in 1902 for 230 vehicles. The company specialized in the sale, storage, valeting and on-demand delivery of electric vehicles that could travel about 40 miles and had a top speed of 20 miles per hour. Built between 1898 and 1906 in Barcelona, Spain, Casa Batllo is the house of the Dragon with its delightful stained-glass windows, a winding roof-back: colorful as a rainbow. Casa Batlló is known for another innovation – the first underground parking anywhere. Designed by the Iconic Architect Antoni Gaudi, it is remarkable for any parking designs for its interior below-grade circular helix built in 1904. The earliest known parking garage in the United States was built in 1918 for the Hotel La Salle at 215 West Washington Street in the West Loop area of downtown Chicago, Illinois. It was designed by Holabird and Roche. The Hotel La Salle was demolished in 1976, but the parking structure remained because it had been designated as preliminary landmark status and the structure was several blocks from
