WorksNo corridor, all corner homes. Four homes share one landing on every floor, each with windows on two sides.
WorksParking is a choice. Surrey sets no resident minimum in a transit-oriented area. The nine stalls serve the market, not the bylaw.
BreaksNothing here is allowed today. R3 allows two homes inside a TOA; MR7 asks for 2,000 m² and 36 m of frontage. This needs a site-specific zone.
BreaksThe stair caps the density. 2.61 FAR against the 3.0 Tier 3 allows. A seventh floor would pass 3.0, but one stair stops at six.

A test fit, not a design. Stall and aisle dimensions, ramp grades, the 6.0 m front and rear yards and the BCBC 3.2.10 conditions all need confirming by a registered architect before a number here is relied on. Source: Form Architects, Small PAB Study, Surrey, October 2026.
