The original plan was for the building to have 5 stories with an extra penthouse single unit on the fitth floor. This was a problematic layout owing to there being very little over shadowing pre-development.
Southwest Environmental were able to inform our client of the maximum possible building height based on the bRE 209 reduction criteria which was around 12 meters in this instance. Th height would change dependent of the scale and distance of the building in relationship to the affected window.
After redcuing the building height to 4 stories the calculations were acceptable, and the rpeort was issued in support of the application.
This report may be used in the appeal process to prove that 4 stories does not create adverse overshadowing conditions.
