 The terrace was later split , and is intersected by Crescent Way , which leads to the Crescent car park . On the southern side of Crescent Way , the northern end of the terrace formed by numbers 15 – 20 , is Exchange House , the former GPO Telephone House . According to Pevsner , this building breaks the modesty of the street , with " its thick @-@ set Tuscan porch " . At the southern end of the same terrace is the Masonic Hall , another Grade II * listed building , which forms the end of the terrace , and features a series of prominent Ionic pilasters along the front and southern end .
