Flow over a single street canyon with balconies located along the leeward and windward walls is studied using large-eddy simulation. The effect of different balcony configurations on the mean flow and turbulence statistics is assessed for height-to-width canyon aspect ratios of AR = 0.25, 0.5, 1.0 and a mean flow perpendicular to the canyon axis. For sufficiently small balconies, the flow continues to be well-described by the canyon aspect ratio; for more closely packed balconies, the applicability of alternative parameters, such as the effective aspect ratio for the interior (ARe) and the balcony aspect ratio for the balcony regions (ARb), is investigated. Over a wide range of balcony configurations, the mean flow, and to a lesser extent the turbulent kinetic energy (TKE), are described by ARe and the normalised balcony separation distance (s'). It is argued that this is a consequence of the flow within the balconies being driven by a canyon-like flow within the interior.
