PPS 7 Addendum Residential Extensions and Alterations·Page 15·A18

Detailing and Window Alignment

Extensions and alterations should align new windows with existing fenestration, match the symmetry of the dwelling, and pay attention to design details such as position, shape, proportion and style of windows and doors to complement the existing property and respect the character of the area.

Attention should be paid to design details such as the position, shape, proportion and style of windows, doors and other features to complement the existing property and respect the character and appearance of the area. To facilitate the integration of an extension or alteration with the existing property, new windows should be aligned to the existing fenestration and match the symmetry of the existing dwelling. The relationship between solids and voids is an essential component of any new proposal, but particularly when extending or altering an existing property where window size and height diminish on upper floors.
