The custom home design process is often shown as a tidy line from sketch to permit. In practice, it advances through a series of decisions. A site finding changes the concept. A cost review sends one part of the plan back for revision. Engineering confirms one idea and forces another to be reconsidered. That movement is normal when each return has a clear purpose.
What matters is knowing when a decision is exploratory and when other work will begin to rely on it. A kitchen can move easily during concept design. The same change becomes wider once structure, windows, mechanical routes, elevations, and pricing have been coordinated around it.
At Amaya Design, Cesar Amaya leads design direction as Founder and Principal. The six phases below explain the work in homeowner terms: what is being solved, what you should expect to see, and what you are being asked to approve before the project moves ahead.
Phase One
A Custom Design Starts With Evidence
The survey, site visit, municipal context, household brief, and budget assumptions establish the questions that concept design must answer.
Key Decisions
The early phases test whether the brief, property, and working budget belong together.
Concept approval should record the tradeoffs accepted, not just the option selected.
Builder pricing is most useful before major design decisions are locked into technical drawings.
The construction handoff should identify one current drawing set and every item still outstanding.
Approval and Handover Facts Worth Planning Around
Planning approval, safety review, and warranty coverage are separate parts of a custom home's path to completion.
The City of Calgary
Development and Building Permits Answer Different Questions
Calgary uses a building permit to review code compliance and safety. A development permit addresses the Land Use Bylaw and a project's effects on neighbouring properties or the wider community, so the two approvals should not be treated as one milestone.

Alberta's Minimum New-Home Warranty Follows a 1–2–5–10 Structure
Minimum coverage is one year for labour and materials, two years for delivery systems, five years for the building envelope, and ten years for major structural components. Those categories are useful checkpoints for specifications and handover records.

Explore Custom Home Design ServicesPhase One: Establish the Project
The opening phase is partly design intake and partly feasibility review. The conversation covers the people who will use the home, the property, rooms and relationships, budget direction, timing, and any builder or consultants already involved. It should also expose information that is missing or assumed.
Read the property before choosing a footprint
Documents establish boundaries and recorded conditions; a site visit provides the physical context. Grade, access, useful trees, adjoining homes, exposure, and promising views can alter the position and shape of the house. On an acreage, driveway length and servicing may influence the first moves. On a compact Calgary lot, the garage, lane, privacy, and remaining yard can become decisive.
Turn requests into a working brief
The brief records required spaces, important connections, flexibility, accessibility, storage, parking, outdoor use, and the priorities that should guide a budget decision. It should distinguish a condition from a solution. For example, needing acoustic separation for work is a condition; putting an office beside the front door is only one possible response.
Phase Two: Compare Design Directions
Concept design concentrates on the moves with the widest effect: where the building sits, how people and vehicles arrive, the organization of the main spaces, connection to the yard, vertical circulation, and the overall exterior massing. Drawings are intentionally less detailed because the team is still comparing directions.
What the homeowner approves
Approval selects a direction and records the reasons for selecting it. It should also identify unresolved parts and the assumptions behind them. If a view depends on tree removal, a walkout depends on grade information, or a room size depends on the eventual mechanical layout, put that condition in the review notes.
Phase Three: Develop the Plan and Test Cost
The chosen concept now gains dimensions, stairs, doors, windows, furniture, storage, ceiling relationships, and service spaces. The plan should be walked in sequences: arrival, food preparation, work, gathering, quiet rooms, laundry, and access to outdoor areas. This is also where the plan is tested against a builder's current pricing input.
Review the plan at a scale you can question
Use actual furniture dimensions where they are known. Check door and appliance clearances, usable wall length, and routes through occupied rooms. Review storage by contents and location. A general label such as 'mudroom' says little about whether the space can handle the household's coats, footwear, equipment, pet supplies, and daily entrances.
Respond to cost feedback deliberately
If pricing is outside the working range, ask which parts of the project are driving the difference and what the estimate includes. A targeted response may align structure, simplify one roof area, tighten low-value circulation, revise the window strategy, or defer an independent feature. Random reductions can leave a smaller plan with the same expensive complexity.
Phase Four: Coordinate the Home as One Building
Design development resolves the relationships that cross between drawings. The interior layout affects windows and exterior composition. Ceiling heights affect sections and roof form. Structural work can affect openings and bulkheads. Mechanical space and routes can change storage or room height if they are considered too late.
Make performance decisions while assemblies can still change
Calgary's heating season, solar exposure, wind, snow, and weather swings give practical importance to the building enclosure, windows, protected entries, roof drainage, and mechanical strategy. These discussions belong with the form and openings because one decision can help or compromise another.
What the homeowner approves
Review every floor, elevation, and major section. Confirm room dimensions, furniture, window sizes and sill heights, ceiling changes, stair relationships, exterior materials, and the remaining selection schedule. A useful review includes side and rear elevations, service rooms, storage, and basement spaces—not only the presentation views.
Phase Five: Prepare the Permit and Technical Drawing Package
The drawing package develops the approved design into coordinated information for approvals, consultant work, pricing, and construction. Depending on scope, it can include a site plan, dimensioned floor plans, roof information, exterior elevations, building sections, details, opening information, and references to consultant documents.
Check relationships, not sheets in isolation
A change to one drawing can affect several others. Moving a window can alter an elevation, structure, energy information, and an interior layout. Changing grade at an exterior door can affect drainage, stairs, and the site plan. Coordination means tracing those consequences and updating the shared issue of documents.
Phase Six: Hand the Current Design to the Builder
Before work starts, identify the issued drawing set and make sure the builder and consultants have it. Review permit conditions, outstanding selections, allowances, long-lead items, site access, and any design matter deliberately left for a later date. Every open item needs an owner and a deadline tied to the construction schedule.
Why There Is No Honest Universal Timeline
The duration depends on property information, project complexity, decision pace, consultant work, pricing iterations, municipal requirements, and whether the brief changes. A schedule should show dependencies rather than promise a generic number of weeks. If survey information or engineering is needed before a decision, that dependency belongs on the schedule.

Common Questions
Answers to Common Planning Questions
What should I bring to the first custom home design meeting?
Bring the property address and survey if available, required spaces, budget assumptions, timing constraints, notes about future household changes, and a few annotated reference images. Include builder or consultant information if those relationships already exist.
Do I need to own a lot before contacting a custom home designer?
No. A designer can discuss the brief and help identify design questions to investigate while you compare properties. Legal, financial, servicing, environmental, and technical due diligence should still be completed by the qualified professionals responsible for those areas.
When should a builder become involved?
A builder can join early or after a concept is established. Their pricing and construction input is especially useful before the design is fully developed, provided the team records which decisions and assumptions the feedback is based on.
Can the design change after concept approval?
Yes, but a later change can affect more work. Before authorizing it, identify the consequences for structure, windows, exterior elevations, consultant documents, energy information, permits, price, and schedule.
Are renderings construction drawings?
No. Renderings communicate form, space, and materials. Measured plans, elevations, sections, details, schedules, and consultant documents provide the technical information used for approvals, pricing, and construction.
Who confirms the final construction price?
The builder or a qualified cost consultant provides current pricing based on a defined scope and drawing issue. The designer coordinates and revises the design information that is being priced.
Before You Start
The Process Protects the Order of Decisions
A staged process does more than divide the fee or schedule. It protects the project from developing detail around an untested premise. Property and brief come before concept; concept and cost are tested before technical coordination; current drawings and open decisions are organized before the site start.
For an initial conversation, bring the survey if you have one, describe what the home needs to accommodate, and be candid about budget assumptions. The first useful outcome is not a finished sketch. It is a shared understanding of what needs to be learned and decided next.
