 The original architectural plan for Savile Row is believed to have been drawn up by Colen Campbell , with Henry Flitcroft as the main architect of the street , under the supervision of Daniel Garrett ; though 1 and 22 – 23 Savile Row were designed by William Kent , who moved into No. 2 . These architects were all under the influence of Burlington 's interpretation of Palladian architecture , known as " Burlingtonian " , which was to have some influence on English architecture in the 16th century . As tailoring moved into the street , the house frontages were altered to bring natural light into the tailors ' working area with the addition of glass frontages and light wells . The houses have been much altered over time ; the original Burlingtonian design has been mostly lost , though No. 14 still retains much of the original external features . When the Royal Geographical Society occupied No. 1 , they built a glass @-@ roofed map @-@ room in the courtyard , a small astronomical observatory on the roof , and a new portico – which may be the basis for the current appearance of the façade .
