Scarborough's slope toward the Bluffs is a design asset: on Guildwood and Cliffside lots the natural grade drop lets us build a legal walk-out basement suite at the front and still place a garden suite at the rear, producing two rentable units from one permit cycle. City of Toronto garden suite rules apply; Scarborough's wide lots also make basement secondary suites with separate walk-out entrances viable alongside a detached unit. Wide suburban lots with grade changes toward the Bluffs, frequently allowing a walk-out basement suite as well as a rear garden suite.
Aging-in-place design plans for a body that will change: blocking in the walls for future grab bars, a bathroom sized for assistance today, and a single-storey layout so the unit never depends on stairs. Single-storey means a wider footprint, so on a Scarborough lot we test the plan against lot coverage and rear-yard soft landscaping before committing to the layout. Proximity is the point - the unit sits on the same parcel as family, so -3.9°C winters never mean a drive across Scarborough to check in.

Wide suburban lots with grade changes toward the Bluffs, frequently allowing a walk-out basement suite as well as a rear garden suite. At 52/100 walkability, Scarborough suites usually keep one parking space: enough to clear the zoning review without surrendering the whole yard. We work regularly in Agincourt, Guildwood, West Hill.

Almost always. A single-storey plan removes the stair as a future failure point, and the cost is a wider footprint that has to clear Scarborough lot coverage. Where coverage is tight, a two-storey unit with a fully self-contained ground floor is the usual compromise.
