done and there was a competition for architectural plans for the development that on 1 January 1813, the results of which were inconclusive. A number of prominent architects were then asked for their opinions: William Stark, James Gillespie, Robert Burn and his son William Burn, John Paterson and Robert Reid and others. Stark's observations were particularly valued and he went on to expand them in a "Report to the Lord Provost, Magistrates and Council of Edinburgh on the Plans for Laying out the Grounds for Buildings between Edinburgh and Leith". Stark died on 9 October 1813, and his report was published posthumously in 1814. The commissioners decided to turn to Stark's pupil William Henry Playfair. He was appointed in February 1818, and produced a plan in April 1819, that closely followed Starks's recommendations. Playfair’s designs were intended to create a New Town even more magnificent than Craig's. Regent Terrace, Carlton Terrace and Royal Terrace on Calton Hill were built, also Hillside Crescent and some adjoining streets, but the development further north in the direction of Leith was never completed. On the south side of Calton Hill various monuments were erected as well as the Royal High School, designed in Greek revival style by Thomas Hamilton.

Other additions A few modest developments in Canonmills were started in the 1820s but none were completed at that time. For several decades the operations of the tannery at Silvermills inhibited development in the immediate vicinity. From the 1830s onward, development slowed but following the completion in 1831 of Thomas Telford’s Dean Bridge, the Dean Estate had some developments built. These included the Dean Orphanage (now the Dean Gallery), Daniel Stewart's College, streets to the Northeast of Queensferry Street (in the 1850s), Buckingham Terrace (in 1860) and Learmonth Terrace (in 1873). In the 19th century Edinburgh's second railway, the Edinburgh, Leith and Newhaven Railway, built a tunnel under the New Town to link Scotland Street with Canal Street (later absorbed into Waverley Station). After its closure, the tunnel was used to grow mushrooms, and during World War 2 as an air raid shelter. Principal losses An attempt to build an elevated walkway along the length of Princes Street involved the planned demolition of the entire street in a radical plan published in the 1960s. The plan was
