A drawing set for a house like this doesn't get judged once. It gets read by a zoning bylaw that doesn't know the lot is an odd pie shape, by a plan checker with a red pen, by an energy model that has to land at zero, and on this lot, by a Board of Variance. Precision Drafters' own scope on it was entirely CAD- and code-based — the drawings, the zoning and energy calculations, and the regulatory case; site work, framing, and inspections were carried out by the builder, their trades, and the City of Burnaby. Seven files, in the order it happened.

Revisions between the first floor-plan sketch and a permit-ready set — because the zoning envelope had to be satisfied by the design itself.Design

An irregular pie-shaped lot, a zoning worksheet revised again and again, and a wall assembly sheet that cites the building code by section number.Code compliance

What the engineering checklist actually requires, where the first submission fell short of it, and how each gap got closed before the permit was issued.Permit & variance

A city reviewer's stamp, applied directly to the drawing sheets — for the design exactly as submitted.Acceptance

RSI 7.3 walls, RSI 10.7 roof, modelled to zero before the foundation went in.Energy modeling

An undocumented fuel tank, a wet-season foundation pour, and the structural coordination it took to keep the envelope on track.Construction milestones

The rendering issued with the permit set, and the house it actually became.Completed

Working drawings, zoning research, Board of Variance application, and energy-model coordination by Precision Drafters. Structural engineering by the engineer of record. Construction by the builder and trades. Plan review, variance hearing, and inspections by the City of Burnaby. Documents and photographs are from the project's own record.
