The Sims lived in the house until they sold it in November 2010 to the current owners.
An old map at the District of North Vancouver offices seems to show the street as the entry to a potential subdivision, with 3355 taking up 3-5 current lots. The original building permit was in June 1950, with another building permit for a lower floor addition in September 1951. In December 1957 the owners were required to remove some other structure that was nonconforming, and in the 1960s the DNV sent letters to two families living there, indicating the single family zoning.
So the structure was originally placed on site in 1950 with no additions, on a big lot at the entrance of the development – then a downstairs addition arrived a year later. But on-site investigations have raised further questions about the phasing of the additions.
