Custom Builds, Renovations & Additions in Cliffcrest

It depends on where the lot sits relative to the stable top of bank of the Scarborough Bluffs, ravine features, and mapped hazard areas. Broadly, lots south of Cathedral Bluffs Drive and any lot backing onto a ravine are more likely to fall within TRCA jurisdiction, but the only definitive answer comes from checking the TRCA’s regulated area mapping against your specific property. We check this as part of every Cliffcrest consultation before any design work begins.

Not as close as most people assume. TRCA requires a minimum setback from the stable top of bank, which is determined by a geotechnical assessment of the specific slope conditions on your property. Setbacks commonly range from 10 metres to over 30 metres depending on slope stability, soil conditions, and erosion history. The buildable envelope is often significantly smaller than the lot suggests, which is why designing for a Bluff-adjacent lot always starts with confirming the setback, not with a floor plan.

Yes, in most cases. The 1940s and 1950s bungalow foundations that define Cliffcrest were built for a single storey, so adding a second floor requires structural review and often foundation reinforcement or new structural steel through the main floor. We handle the engineering as part of design so the addition is designed to what the structure can actually support, not what looks good in a rendering. Second-storey additions typically pair with full main-floor renovation to justify the disruption and produce a coherent home.

Yes, though it varies significantly by property. The Scarborough Bluffs are actively eroding sandy cliffs, and the rate of retreat depends on the specific geology, drainage, and vegetation of each section. TRCA setbacks are designed to keep buildings well clear of the projected erosion line over decades, and geotechnical assessments account for site-specific conditions. Homes built properly behind proper setbacks are not typically at risk, but properties closer to the edge require careful evaluation. We assess erosion history and stability as part of the pre-design work.

Cliffcrest lots skew larger than most of Toronto. Frontages of 45 to 60 feet are common, and depths often exceed 150 feet, particularly on streets running perpendicular to the lake. Bluff-adjacent lots may have irregular shapes because the top of bank isn’t a straight line. Some lots have ravines on multiple sides. Deep lots support larger builds, rear additions, and garden suites, but the buildable envelope depends on zoning setbacks and any TRCA constraints.

Often yes, particularly on the deeper Cliffcrest lots where an existing detached garage can be replaced. Garden suite eligibility depends on lot dimensions, existing structures, City of Toronto zoning rules, and any TRCA constraints where applicable. On Bluff-adjacent lots, TRCA setbacks apply to the garden suite as well as the main home, which may limit placement. We assess feasibility during the consultation before design work begins.
