Brighton Vale is a cul-de-sac on the seaward side of the railway at Seapoint, Monkstown. At its eastern end Brighton Vale road rises to cross the railway line and join Seapoint Avenue. This vehicular access crosses the Built Heritage structure of Tower Bridge. At the western end of Brighton Vale a narrow footbridge provides a second link onto Seapoint Avenue for pedestrians.

The terrace was almost certainly designed by John Skipton Mulvany, (1813-1870) who lived there for a short while around 1843.  Mulvany designed the Kingstown railway station, Longford Terrace, The Royal St George Yacht Club and many other buildings in the area and elsewhere.
