The last house was completed in 1637.[60] Seventeen of the houses had arcaded portico walks organised in groups of four and six either side of James Street on the north side, and three and four either side of Russell Street. These arcades, rather than the square itself, took the name Piazza;[2] the group from James Street to Russell Street became known as the "Great Piazza" and that to the south of Russell Street as the "Little Piazza".[60] None of Inigo Jones's houses remain, though part of the north group was reconstructed in 1877–79 as Bedford Chambers by William Cubitt to a design by Henry Clutton.[61]
