Aerial view of St Albans, Hertfordshire

St Albans AL1/AL3/AL4 is one of the largest and most varied Hertfordshire towns Herts Build covers — a Roman and medieval city core, Georgian townhouses, Victorian terraces, and substantial interwar semi-detached suburbs. Sixteen separate conservation areas cover the city, including the Cathedral, Romeland, Sopwell and Fishpool Street.

St Albans housing stock. Marshalswick, on the east side of the city, is dominated by 1930s interwar semi-detached houses — the closest match in St Albans to the Barnet housing stock Herts Build knows best. Fleetville has denser Victorian terraced streets. The historic core around Holywell Hill, the High Street and St Peter’s Street is largely Georgian townhouses with uniform building heights, and George Street near the Cathedral retains medieval timber-framed buildings on narrow burgage plots — both heavily protected.

Extensions in St Albans. Marshalswick’s 1930s semis take standard single-storey rear kitchen extensions comfortably under permitted development, much like the equivalent Barnet streets. Fleetville’s narrower Victorian terrace plots are usually better suited to a side-return extension.

Lofts in St Albans. Marshalswick’s 1930s semis are strong dormer and, where hip-roofed, hip-to-gable candidates. Fleetville’s Victorian terraces suit an L-shaped dormer using the full width of the original rear addition roof.
