1980s including HMV, Next, River Island, Miss Selfridge, and Marks & Spencer. In 1987, a major fire broke out on Grafton Street in an employment agency above two shops. The fire quickly spread through the property, causing significant damage and closing the street. Five people were hospitalised for shock and smoke inhalation. Several properties on the street were refurbished in the 1990s. No. 70 was extended in 1992, adding a Limestone frontage on the ground floor. Numbers 84–86 were rebuilt the same year in a post modern brick style. In 2008, Grafton Street was the fifth most expensive main shopping street in the world, with rental pricing of €5,621/m2/year, and the thirteenth most expensive main shopping street in the world in 2016 at rental pricing of a much lower region of €3,300/m2/year. Pedestrianisation By the 1960s, Grafton Street had become congested with cars and buses, which caused serious pollution. Pedestrianisation of the street was first trialled in September 1971, for a period of 4 weeks. After many delays, permanent pedestrianisation of most of the street was established in 1982, and the street was then repaved in 1988, with new street lighting also fitted. Objections to pedestrianisation came from councillors and small business owners, who alleged that it would lead to an increase in petty crime and antisocial behaviour. The northern end of the street, between Nassau Street and College Green, one side of which is occupied by the walls of Trinity College, is not pedestrianised. Properties Grafton Street has had a number of periods of redevelopment in its history, including in the 1860s, 1880s, early 1900s, and 1990s. On some occasions, the demolition of buildings led to the collapse of some of their neighbours. Altogether, this activity has resulted in a mixture of periods and styles, with few notable interiors or street surfaces extant. Some of the Georgian plot sizes and facades are still visible on some buildings, such as Nos. 31–33 and 63. No. 14 retains the window pattern of an early Dutch Billy house. At the north end of Grafton Street, surviving largely intact, is the Provost's House, Trinity College, home to the head of the college and the University of Dublin. The English Grammar School was founded at No. 75 Grafton Street in 1758, by Samuel Whyte, first cousin in law of the actor and impresario Thomas Sheridan. Students included Richard Brinsley Sheridan, Robert Emmet, Thomas Moore
