6 McLeod St., Golden Triangle, Ottawa

 Let's call this the Martin Rosenthal House. 

#6 McLeod sits inside the "triangle-within-a-triangle" — the area that was, until 1900-ish, the C.A.R. / Bronson & Weston lumber yard, as bounded by Frank on the north, Cartier on the west, and the Rideau Canal as the hypothenuse. The removal of the lumber stacks and their dense network of train-tracks opened up some 15 acres of centrally located land for homebuilding, right next to the newly built Federal Driveway and its associated canal-side linear park. 

#6 appears in the news as early as 1908 and is listed in the City Directory that same year as the home of Martin Rosenthal, jeweller.

Talking about triangles, #6 sits on a triangular lot and has a roughly triangular footprint thanks to its acutely cross-gabled plan. This layout makes it hard to decide whether the "real" front entrance faces onto McLeod or the Driveway. Both facades are charming, neither is overbearing. Goad 1912 shows all wood — in-person inspection reveals a very solid-looking limestone foundation with a BV ground floor and stucco on the second. While its complexity is arguably last-gasp Victorian, exterior styling gives nods to Craftsman and Mission-revival.

The house, whether rented or sold, became the home of Gerald H. Brown, Assistant Deputy Minister of Labour, no later than January 1910.
