How to Structure Your Ontario Renovation Team in 2026
The delivery model you choose shapes your project’s cost, quality, timeline, and stress level. Here’s the honest breakdown.
Model 1: Separate Designer + Competitive Tender
You hire a designer (interior designer, architect) who produces full drawings and specs. You send these to 3+ contractors for competitive bids.
Pros:
- Design quality is highest
- Competitive bidding = best pricing on clearly defined scope
- Designer acts as your advocate during construction
Cons:
- You manage the designer-contractor relationship
- Potential conflicts: designer wants premium finish, contractor wants to build fast
- Higher upfront design cost ($5,000–$25,000 before a nail is swung)
Best for: Projects over $150,000 where design vision is primary. Additions, full-home renovations.
Model 2: Design-Build
One firm handles both design and construction under a single contract.
Pros:
- Single point of accountability
- Faster project start (no tender phase)
- Cost knowledge informs design = fewer surprises
- Simpler communication
Cons:
- Harder to price-check without competitive bids
- Design may be constrained by the firm’s construction approach
Best for: Complex projects where you want simplicity. Full home renovations, major additions.
Model 3: Contractor-Led with In-House Layout
Established contractor has design staff or works with preferred designers. Produces working drawings for permit but not architect-stamped.
Pros:
- Efficient, practical
- Often best value for mid-range work
- Less upfront design cost
Cons:
- Limited architectural sophistication
- Not suitable for structural complexity
Best for: Kitchens, baths, basement finishes under $100,000 without major structural work.
