[单选题]The elegant f 20m extension of Tate St Ives,a gallery that was overwhelmed by its own success when it opened in 1993,has won the&100,000 museum of the year award,the most lucrative museum prize in the world The artist Melanie Manchot,one of the judges,said it had been"a profound experience"to visit after the work,which she believes has transformed the gallery As soon as I walked into Tate St Ives I had an amazingly strong feeling that they're doing some thing innovative.Ive visited before,but now the whole building,the galleries,the views,all feel different-they have been given a new lease of life.The extension has not so much been an addition as a complete reimagining The St Ives gallery beat a strong shortlist,including the Ferens Art Gallery in Hull which was completely refurbished in time for Hull's term in 2017 as city of culture The other contenders were the Brooklands Museum in Weybridge,where the finishing straight of the world's first purpose-built motor-racing circuit was restored the Glasgow Womens Library-the only one in the UK dedicated to womens history-which has grown over 25 years from a shopfront with no funding to an award-winning resource in a listed building;and the Postal Museum in London,once a niche archive with 3,000 visitors a year,but now a purpose-built museum with a spectacular attraction in Mail Rail,the restored train that once carried post far below the capital's streets Tate St Ives reopened in October 2017.Visitors surged back in,and there were 11,000 visitors over the opening weekend alone.The project involve refurbishing the orginal galleries,and adding an extension by Jamie Fobert Architects and the environmental engineering company Max Fordham.The original museum opened in a town that had been famous for its artists,including Barbara Hepworth and Ben Nicholson.It was built on a spectacular but tight site,designed by the architectural practice Evans&Shalev directly overlooking the beach on the footprint of an old gasworks.In its first six months,there were 120,000 visitors;the gallery had planned for 50,000 visitors a year.Tate St Ives has since averaged 240,000 visitors annually swamping the gallery spaces,overwhelming the shop and other visitor facilities,and causing queues down the stairs for the rooftop cafe.The whole gallery had to be closed every time a new exhibition was hung The original proposal to extend produced a rash of"Stop the Tate"posters in windows throughout he town,and protests about everything from property prices being driven up by arty incomers to the loss of parking spaces After extensive public consultation,the architects'eventual solution was to double the gallery space by excavating into the hillside behind the original building--which drove up the cost to f 20m from the original estimate of 12m.

A.Because it may impact its surroundings
B.Because it may bolster the housing prices
C.Because it needs more parking spaces
