The general contractor model
In the traditional model, the homeowner hires an architect (or designer) separately from the builder. The architect creates the design and drawings. The homeowner then takes those drawings to one or more general contractors for pricing. The selected GC builds what the architect designed.
The advantage of this model is independent oversight. The architect acts as the client's advocate during construction: reviewing the builder's work, processing change orders, and ensuring the design intent is maintained. The GC and the architect operate as a check on each other. When your contractor says a detail can't be done, your architect can push back. When your architect specs something impractical, your contractor catches it. That tension, when it's professional and constructive, produces better buildings.
The disadvantage is that design and construction happen in sequence, not in parallel. The architect designs what they think is buildable at a certain budget. The GC prices it and often comes back higher, sometimes 20 to 40% higher. Then there's a value engineering phase where the design gets modified to meet the budget. This cycle can add three to six months to the pre-construction timeline, and we've seen it go longer on complex North Shore projects where the site work alone is a $200,000 variable.
There's also a communication challenge. The homeowner sits between two parties who may not agree on approach, schedule, or cost. When the architect designs a detail that the builder finds impractical (say, a cantilevered deck over a ravine that needs $80,000 in structural steel), the resolution takes longer because there's no shared accountability. The architect defends the design. The builder defends the budget. The homeowner referees.
The design-build model
In the design-build model, one firm handles both design and construction. The homeowner has a single contract, a single point of contact, and a team that's designing with construction cost and feasibility in mind from day one.
The advantage is efficiency. Design and preconstruction planning overlap. The builder's cost knowledge informs the design in real time, so the drawings are buildable at the target budget from the start. There's no adversarial pricing phase, and change orders are less common because the team that designed the project is the team building it.
The disadvantage is reduced independent oversight. With the same firm doing both design and construction, there's no third-party check on the builder's work. You're trusting one organization to both design it right and build it right. That trust needs to be earned: through references, through a portfolio you can actually visit, and through a contract that gives you real recourse if things go sideways.
Design-build firms on the North Shore typically employ or subcontract their own designers and draftspeople. Some have licensed architects on staff; others use architectural technologists or building designers. The distinction matters. A building designer can produce construction drawings for most residential projects in BC, but an architect brings a different level of design thinking. Ask which you're getting.
The third option: Construction Management
There's a hybrid model that doesn't get enough attention: Construction Management, or CM. In this arrangement, the homeowner hires both a designer/architect and a construction manager. The CM works alongside the design team during the design phase, providing real-time cost feedback, and then manages the construction using the homeowner's direct contracts with trade subcontractors.
The CM doesn't hold the trade contracts. The homeowner does. The CM manages the schedule, coordinates the trades, reviews invoices, and oversees quality. The homeowner gets full transparency into every cost because they're paying the trades directly, and the CM charges a management fee, typically 10 to 15% of construction cost, or a fixed monthly rate.
This model gives you the independent design of the traditional model with the cost transparency you'd normally only get in design-build. The downside? More paperwork for the homeowner. You're signing contracts with every subtrade. You're technically the employer of record for WorkSafeBC purposes unless the CM holds the prime contract, and that distinction matters for liability. It also requires a CM who's genuinely skilled at coordination, not just a GC who's rebranded their services.
On the North Shore, the CM model works well for clients building in the $2M to $5M+ range who want full control and are willing to be more involved in the process. It's less common for renovations under $500K where the overhead doesn't justify the structure.
Cost differences: with real numbers
The design-build model is often presented as cheaper. In some cases it is, because the design is constrained by budget from the start, and the value engineering happens during design rather than after. But 'cheaper' and 'better value' aren't the same thing.
In the traditional model, the architect's design might be more ambitious, more architecturally expressive, and more tailored to the client's vision. The construction cost might be higher, but the result might be meaningfully different. Whether that's worth the premium depends entirely on the client.
Here's what the numbers look like for a 3,500 sq ft custom home on a typical North Shore lot in 2026:
- Traditional model. Architectural fees: $120,000 to $200,000 (8 to 12% of construction). GC markup: 15 to 20% on top of trade costs. Total soft costs before construction: $180,000 to $300,000. Construction: $1.4M to $2.1M. You'll likely go through one to two rounds of value engineering, adding 2 to 4 months.
- Design-build model. Design fees (rolled into contract): $50,000 to $100,000. Single contract with 18 to 25% builder margin (design + construction combined). Total project: $1.3M to $1.9M. Typically 10 to 15% lower total cost than traditional, but the design scope is narrower.
- CM model. Architectural fees: $100,000 to $180,000. CM fee: 10 to 15% of construction cost ($140,000 to $250,000). Trade costs are direct: no GC markup, but you lose the volume pricing a GC negotiates. Total: $1.4M to $2.2M. You see every dollar, but you manage more of the process.
Contract types under each model
The delivery model determines what kind of contract makes sense, and the contract type determines how risk is shared between you and the builder. This is where people get tripped up: they focus on the project delivery method without understanding the financial structure underneath it.
- Fixed-price (stipulated sum): The GC or design-build firm quotes a total price for the defined scope. You know the number upfront. The builder absorbs cost overruns on included scope. Common in both traditional GC and design-build. Works well when drawings are complete and detailed. On the North Shore, insist on clear language about what happens when you hit rock during excavation or discover an unmapped storm drain, because those aren't 'included scope' items.
- Cost-plus, You pay actual costs (labour, materials, subtrades) plus a fee, either a percentage (usually 12 to 18%) or a fixed fee. The builder has no incentive to cut corners, but also less incentive to control costs. This is the standard contract type for the CM model. It's also common in high-end custom homes where the scope evolves during construction.
- Guaranteed Maximum Price (GMP). A hybrid: cost-plus with a ceiling. The builder charges actual costs plus a fee, but guarantees the total won't exceed an agreed maximum. If it comes in under, the savings are shared (typically 50/50 or 60/40 in the homeowner's favour). If it goes over, the builder eats it. GMP contracts are increasingly popular on the North Shore for projects in the $1.5M to $4M range. They give you cost transparency with a safety net.
How change orders work under each model
Change orders are where the delivery model really matters. A change order is any modification to the agreed scope: whether it's something you requested, something the design team missed, or something the site conditions forced.
In the traditional GC model, change orders go through a formal process. The architect reviews the request, the GC prices it (with their markup), the architect checks the pricing, and the homeowner approves. It's deliberate and documented, but slow. A single change order can take one to three weeks to process. On a North Shore custom home, we typically see 15 to 30 change orders over the life of a project, ranging from $500 adjustments to $50,000 scope additions.
In design-build, change orders are simpler because the same team handles design and construction. If you want to upgrade the kitchen countertops or add a built-in, the design-build firm prices it internally and presents it to you. Faster turnaround, often same-week. But here's the catch: without an independent architect reviewing the pricing, you have less visibility into whether the change order cost is fair. A $15,000 change order might include $3,000 in actual material cost, $7,000 in labour, and $5,000 in margin. In the traditional model, your architect would flag that margin.
In the CM model, change orders are the most transparent. The CM gets trade pricing directly, marks it up by their agreed fee percentage, and presents it with backup documentation. You see the subtrade quote, the CM's fee, and the total. It takes a bit longer than design-build but you know exactly what you're paying for.
The architect-builder relationship
This is the part nobody talks about until there's a problem. The relationship between your architect and your builder shapes the entire construction experience, and the two delivery models create very different dynamics.
In the traditional model, the architect and builder are separate entities with separate interests. A good architect pushes for design quality. A good builder pushes for buildability and cost control. When both are experienced and professional, this tension produces excellent results. When they don't get along (or when the architect has no site experience and the builder has no patience for design intent), it produces six months of arguments and a homeowner caught in the middle.
We've worked with architects on the North Shore who understand construction deeply: they spec practical details, they respond to RFIs within days, and they visit the site regularly. We've also worked with architects who produce beautiful renderings but whose construction documents are incomplete, leading to dozens of field decisions that should have been resolved on paper. The difference in project cost between a good set of drawings and a bad set can be $100,000 to $200,000 in change orders and rework.
In the design-build model, the architect (or designer) works for the builder. The design serves the construction process, which keeps things efficient but can mean the design is less ambitious. Some design-build firms employ talented designers who push creative boundaries within the builder's capabilities. Others produce competent but formulaic work. The question to ask a design-build firm is: show me three projects where the design surprised you. If they can't, the design component may be an afterthought.
Insurance and liability differences
This is dry but it matters, especially on the North Shore where a construction defect involving water management can mean $300,000 in remediation.
In the traditional model, liability is split. The architect carries professional errors and omissions (E&O) insurance, typically $1M to $5M. The GC carries commercial general liability (CGL) insurance and often a builder's risk policy. If a design defect causes a construction problem, the architect's E&O responds. If a construction defect causes damage, the GC's CGL responds. If it's both (a design that was buildable but poorly detailed, constructed exactly as drawn but still fails), you may need to make claims against both policies. This happens more than you'd think, particularly with building envelope issues in our coastal climate.
In the design-build model, one firm holds both the design and construction liability. Their insurance should cover both, but verify this. Some design-build firms carry CGL but not E&O, which means design errors might not be covered. Ask to see their certificate of insurance and confirm it includes professional liability for design services. On a $2M+ project, you want to see at least $2M in CGL and $1M in professional liability.
In the CM model, liability gets complicated. The CM typically carries professional liability for their management services. But since you hold the trade contracts directly, each subtrade's insurance is your concern. Your CM should be verifying insurance certificates from every subtrade before they start work, and you should have an umbrella policy. Talk to your insurance broker before choosing this model.
How each model handles permits on the North Shore
Permits are a defining feature of building on the North Shore. The District of North Vancouver and the City of North Vancouver have different processes, different timelines, and different requirements, and both are slower than most of Metro Vancouver. A building permit for a custom home in the District currently takes 12 to 20 weeks from submission to issuance, assuming no resubmissions. The City is slightly faster at 8 to 14 weeks.
In the traditional model, the architect prepares and submits the permit drawings. They respond to plan checker comments and manage resubmissions. The GC is typically not involved until the permit is issued, or close to it. This means the builder has no input on constructability during the permit process. We've seen permit drawings that specified a foundation system that couldn't work on the actual soil conditions, discovered only after the permit was issued and the GC started pricing.
In design-build, the firm manages the permit process end to end. Because the builder is involved during design, the permit drawings already reflect constructability. The design-build firm handles submissions, responds to comments, and coordinates with the municipality. This is particularly valuable in the District of North Vancouver, where the environmental review (tree surveys, drainage analysis, erosion and sediment control plans) is extensive and benefits from a builder's site knowledge.
For either model on the North Shore, expect the full permit timeline (from initial design through permit issuance) to be 6 to 12 months for a custom home. That's before construction starts. If your lot is in a Development Permit area, in a floodplain, or near a watercourse, add another 2 to 4 months for the additional approvals.
Timeline comparison: a typical North Shore custom home
Let's compare timelines for the same project: a 3,200 sq ft custom home on a sloped lot in the District of North Vancouver, moderate complexity, no unusual environmental constraints.
- Traditional model. Schematic design: 2 to 3 months. Design development and construction documents: 3 to 5 months. Permit process: 4 to 5 months. GC selection and pricing: 1 to 2 months. Value engineering: 1 to 3 months. Construction: 12 to 16 months. Total: 23 to 34 months from first architect meeting to move-in.
- Design-build model. Design and preconstruction (overlapping): 3 to 5 months. Permit process: 4 to 5 months. Construction: 11 to 14 months. Total: 18 to 24 months. The savings come from overlapping design and preconstruction, eliminating the GC selection phase, and reducing value engineering.
- CM model. Design: 2 to 4 months (with CM input from month one). Permit process: 4 to 5 months. Trade procurement: 1 to 2 months. Construction: 12 to 15 months. Total: 19 to 26 months. Similar to design-build in overall timeline, but the procurement phase adds a step that design-build avoids.
Value engineering: what it actually means
Value engineering is the process of reducing cost without reducing function or quality. It's one of those terms that sounds clinical, but it's actually the most consequential phase of any custom home project. Done well, it saves $100,000 to $300,000 without compromising the design. Done poorly, it strips everything that made the project worth doing.
In the traditional model, value engineering happens after pricing, when the GC's number comes back over budget. The architect and GC go through the drawings line by line. Common targets: simplifying the roof geometry (a hip roof costs 15 to 25% more than a gable), reducing window sizes or switching from custom to standard sizes, changing the foundation type, substituting exterior cladding materials, and adjusting the mechanical system spec.
The problem is that value engineering at this stage means redesigning parts of the project. The architect has already invested months in the design. The client has fallen in love with the renderings. Cutting $200,000 means changing the building, not just swapping a countertop material. That's emotionally difficult and architecturally painful.
In design-build, value engineering happens during design. It's baked into the process. The builder's estimator or project manager sits in design meetings and flags cost drivers in real time. That $40,000 curved glass wall? The team discusses it before it's drawn, not after. The result is a design that was always buildable at the budget, but it also means some ambitious ideas never make it to paper. Whether that's a feature or a bug depends on what you value.
Good value engineering targets structural and systems choices, not finishes. Switching from a post-tensioned slab to a conventional foundation on the right soil type can save $60,000. Simplifying the HVAC zoning can save $15,000 to $25,000. Changing the framing from steel to engineered wood where code allows it can save $40,000 to $80,000 on a 3,500 sq ft home. These are the decisions that matter, not whether the faucets cost $800 or $1,200.
When design-build goes wrong: warning signs
Design-build works well when the firm is genuinely good at both design and construction. It goes wrong when a builder adds 'design' to their name without adding actual design capability. Here's what to watch for:
- The 'designer' is a draftsperson, not a designer. They can produce drawings but they're tracing the builder's standard plans with minor modifications. If every project in the portfolio looks like a variation on the same house, that's a drafting service, not a design service.
- No independent engineering: The design-build firm uses the same structural engineer on every project and the engineer has never pushed back on anything. Good structural engineers say 'you could do that, but here's a better way.' Captive engineers say 'whatever you want.'
- The contract bundles design fees into construction. You can't see what you're paying for design versus construction. If you cancel after design, you have no drawings and no recourse. Insist on a separate design phase with a defined deliverable: at minimum, permit-ready drawings that you own.
- No third-party inspections: A reputable design-build firm welcomes independent inspections. If they resist you hiring your own building envelope consultant or structural inspector, that's a red flag worth acting on.
- Change order pricing is opaque. They give you a total but won't break it into labour, materials, and margin. In design-build, you're trusting one firm for everything. That trust requires transparency.
Same project, two models: how it plays out
Let's take a real scenario: a family wants to build a 3,800 sq ft home on a 7,000 sq ft lot in Upper Lonsdale. The lot has a 20% grade, a few significant trees, and a view of the harbour they want to capture from the main living floor. Budget: $2.2M for construction (excluding land and soft costs).
Under the traditional model, they hire an architect known for West Coast modern design. The architect spends four months on schematic design and design development: cantilevered living room to capture the view, green roof on the garage, floor-to-ceiling glazing on the south face. Beautiful drawings. The architect estimates construction at $2.2M. Three GCs price it: $2.6M, $2.8M, $2.9M. The lowest bid is $400,000 over budget. Two months of value engineering follow. The green roof becomes a conventional roof, the cantilever shrinks, some windows become standard sizes. Revised price: $2.35M. The family accepts it, slightly deflated but still excited. Total timeline from first meeting to permit: 14 months.
Under design-build, the same family goes to a reputable design-build firm. The firm's designer proposes a similar orientation to capture the view but uses conventional structural approaches: no cantilever, standard window sizes in strategic locations, a simpler roof form. The design is good: clean, functional, well-suited to the lot. The firm prices it during design at $2.1M. No value engineering phase needed. The family approves. Total timeline from first meeting to permit: 7 months. They save $250,000 and seven months, but the house is a different house. Not worse, necessarily. Different.
Which outcome is better? That depends entirely on what this family values. If the architecture matters deeply to them (if they want a house that makes a statement), the traditional model, even with its inefficiencies, might produce a result they love for thirty years. If they want a well-built, well-designed home without the drama, design-build gets them there faster and cheaper.
How RealDream works with architects and designers
RealDream operates primarily as a general contractor and project manager. We work with the client's architect and design team, and we also offer in-house interior design services. For clients who come to us without an architect, we can recommend design professionals we've worked with across the North Shore: architects, building designers, interior designers, and landscape architects who understand the local conditions and municipal requirements.
What we push for, regardless of the delivery model, is early involvement. The single biggest source of budget overruns in residential construction is the gap between what gets designed and what gets priced. If the builder is at the table during design (even informally, even just reviewing drawings at key milestones), that gap shrinks dramatically.
On a typical project, we'll do a preliminary budget review at the schematic design stage (before the design is fully developed). This takes a week and costs nothing. It's part of how we build relationships. We flag the big-ticket items early: is the foundation going to be $120,000 or $250,000? Is the site access going to require a crane for framing? Is the tree protection going to limit where we stage materials? These are the questions that determine whether a project is buildable at the target budget, and they're best answered before the architect has spent three months on construction documents.
We've built homes designed by some of the best architects on the North Shore, and we've also guided clients through projects where they hired us to manage the full process with our design partners. Both approaches work. The key is matching the model to the client. Their priorities, their budget, their tolerance for complexity, and honestly, how involved they want to be in the process. Some clients want to attend every site meeting. Others want a monthly update and a move-in date. Neither is wrong, but they point to very different delivery models.
