four storeys, while the other seven houses are one storey shorter. All houses except number 12 have a single bay window, mostly in tripartite form. Number 12 has three windows to each floor. The entrance porches, reached via staircases, are either Doric or Ionic in form, with columns and entablatures. They have arch-headed doorways set into them. Small cast-iron balconies run across the terrace at first-floor level (although number 5's has been lost), and some houses have canopy-style verandahs as well. A nearly continuous cornice (absent on numbers 13 and 19) spans the terrace; some houses also have a second cornice above this. Several houses have fanlights with coloured glass, and other non-standard details include decorative stucco panelling at number 5; paterae (circular motifs), triglyph-decorated friezes and other Classical-style ornamentation in some of the porch entablatures; original window-guards of iron; a blocked doorway flanked by pilasters at number 20; and many original sash windows. 26–37 Regency Square These 12 houses, arranged along the sea-facing north side in the form of two wings flanking a four-house centrepiece, are the focal point of the square, forming "a kind of palace front" topped with a pediment displaying in prominent black lettering. Pevsner described this feature as "not [being] enough of an accent to pull the square together". The terrace is a five-part composition: the end "wings" (formed by numbers 26–27 and 36–37) are of four storeys, stuccoed and with tall parapets pinched upwards to form small pediments; the central section (numbers 30–33), also of four storeys and built in yellow brick, and topped with the inscribed pediment; and numbers 28–29 and 34–35, rising to three storeys and forming a link between the central and outer sections. Numbers 30–33 have a two-window range, rather than the single window on each of the other houses, and have four pilasters running the full height of the façade and terminating at the parapet in circular antefixae. The entrance porches are of the Ionic order. Each house has a canopied cast-iron balcony at first-floor level. There is rusticated decoration at ground-floor level. 51–56 Regency Square The east side of Regency Square is architecturally less consistent than either the north or west sides. Numbers 51–56 were designed as a symmetrical composition: the two houses at the centre stand forward slightly and have a more prominent pediment. Each house has four storeys and a single bay window on the ground
