Bayview Village Ravine House, Toronto

This existing 1 storey bungalow with walkout basement on a ravine lot on a quiet street underwent a complete transformation with the addition of a second storey, front porch and bay windows into a modern dwelling with 10’ main floor and 9’ second floor ceilings.

The front porch is introduced as the key element to fit with the neighbourhood’s character and to tone down the scale of the second storey addition. The original compartmentalized ground floor is replaced with an open plan to showcase the ravine backyard and to create an airy interior as the home owners’ oasis.
