Demonstration project · West Coast, British Columbia
Prepared for Private client · Architect Withheld · Landscape Withheld Date Monday, August 17, 2026
Interactive demonstration · figures illustrative, adapted from a completed BDG cost plan
Part one
Where the money goes
Hard costs of $7.39M carry three markups — a 10% contingency, a 10% contractor fee and 5% GST — to reach the all-in total. The main house is roughly two-thirds of the project.

How $7.39M of hard costs becomes $9.39M
The markups add roughly $2.00M on top of construction

Before contingency, fee and tax
Cost per square foot, before tax
Living space runs $1,200–$1,350/sf; the accessory garage is the cheap outlier
Part two · interactive
Value engineering worksheet
Flip a switch to apply a reduction. The all-in budget at the top updates instantly — each hard-cost saving also removes its share of contingency, fee and GST (a 1.27× effect). Nearly half the total savings sit in one decision: phasing the coach house and garage.

How to use this. Toggles capture hard-cost reductions only; the budget at the top automatically grosses each one up by contingency, contractor fee and GST. The countertop and backsplash entries are listed as the consultant staged them (mid-level quartz, then a further step to Silestone) — applying both reflects the deepest downgrade. Phasing the coach house and garage is a scope decision, not a finish decision, and also trims about 1,900 sq ft. All figures are illustrative — scaled and rounded from a completed BDG cost plan.
