All our shadow diagrams are "SITE SPECIFIC", not generic. Vertical shadow diagrams are illustrated as an isometric perspective and as an elevation, of any neighbouring building that may be impacted. Typically we will provide a diagram for each hour between 9am and 3pm on Winter Solstice. In some cases, we have provided diagrams for every 15 minutes and for 1 month on either side of the solstice.

Below: No Survey information was available for the project below.  To double check that we were using a correct North point, a photograph was taken of existing shadow cast on a window and then compared to our diagrams.  The diagrams were shown to be very accurate.
