The 50 buildings, some subdivided, forming the headline Wilton Crescent addresses are listed at Grade II. The crescent is split into three terraces of lengthy proportion buildings, plus 31 which forms a terrace with 1-15 Grosvenor Crescent, plus 32 and 33 which face the opposing side of a brief continuation of the eastern broad link into Belgrave Square which form a terrace with 1-11 Belgrave Square. The western broad link into Belgrave Square is however termed Wilton Terrace, split into 1-3 Wilton Terrace and is of identical date, style and proportions. George Bernard Shaw's 1905 play "Major Barbara" is partly set at Lady Britomart's house in Wilton Crescent. Of the main two quadrants and main facing return of the crescent, forming 47 of the 50 buildings, the first floor has stucco-applied doric order pilasters between the windows and a subsidiary cornice above. The second and third floors are united by paired ionic order pilasters set between houses. These are surmounted by a heavy modillion cornice. Most have a balustrade finished with urns to the final unit. They have dipped parapet walls with ball finials.
