What a Build
returns

Site planTo scale on the real parcel, with setbacks, neighbours, the ramp and the nearest station.
Floor plansParkade, ground, typical and roof, with every home labelled and measured.
Section and elevationThrough the core and from the street, with levels and the height limit.
StatisticsFloor area, FAR against the plan, unit mix, parking, bikes, amenity, excavation.
Code checklistEvery 3.2.10 condition with the clause behind it, and what is left to confirm.
Pre-application summaryOne page a planner can read: the plan, the tier, the zone, the ask.
Schematic only

A Build is a schematic design and a test fit, not a permit set. Every scheme must be verified and sealed by a registered architect before it is relied on, priced or submitted. Stall and aisle dimensions, ramp grades, setbacks, servicing and the BCBC 3.2.10 conditions all need confirming for the specific site. Form Architects can carry any Build into a tailored scheme.
