By the 1930s and 1940s the original owners were beginning to age and the fussily detailed houses of Grey Lynn on their cramped sections were seen as very old-fashioned and undesirable. The increased ownership of motorcars meant suburban development was expanding exponentially, resulting in the mid-20th century ideal of the quarter-acre section. All the inner suburbs of Auckland became less desirable, and areas like Grey Lynn became very rundown. Many properties became owned by people who lived elsewhere and were often divided into flats or operated as boarding houses. Repairs were kept to a minimum and in some cases houses were not repainted for almost half a century. The fact that so many houses of this period still stand today despite the depredations of fire, rot and borer is an indication of how well they were built.
