When clients begin exploring a custom home build, one of the most common areas of confusion is what the "design" phase actually delivers. Terms like drafting, design development, construction documents, and 3D renderings get used loosely and often interchangeably — but they represent distinct phases and deliverables with different purposes. Understanding what's included helps you evaluate proposals accurately and set the right expectations for the process.
Phase 1: Schematic Design
The schematic design phase is where the home begins to take shape on paper. The work in this phase focuses on establishing the overall concept: the relationship between spaces, the flow of the floor plan, the massing of the building, and the general character of the exterior.
Deliverables typically include:
- Preliminary floor plans at a reduced scale, showing room layout and adjacencies
- Site plan showing the home's footprint relative to the lot and setbacks
- Preliminary exterior elevations showing the general massing and character of each facade
- 3D concept sketches or renderings (depending on the scope of service)
The purpose of this phase is to confirm that the direction is right before significant detail work begins. Changes at the schematic level are inexpensive. The same changes made during construction documents or construction itself are not.
Phase 2: Design Development
Once the schematic design is approved, design development refines and extends that concept into greater detail. Room dimensions are confirmed, structural systems are coordinated, and major component decisions (kitchen layout, bathroom configurations, built-in storage, fenestration) are made.
Deliverables in this phase include:
- Refined floor plans with confirmed dimensions and room layouts
- Developed exterior elevations showing materials, window styles, and architectural details
- Key interior elevations for kitchens, bathrooms, and feature spaces
- Coordination with structural engineer for preliminary framing design
- 3D renderings that provide a realistic visual preview of the finished home
Phase 3: Construction Documents
Construction documents are the full technical package used to build the home and obtain building permits. These are detailed drawings that leave nothing ambiguous — every structural connection, mechanical penetration, and finish detail is specified.
A complete set of construction documents includes:
- Architectural drawings: floor plans, elevations, sections, and construction details
- Structural drawings: engineered framing plans, connection details, and specifications
- Mechanical, electrical, and plumbing schematics (often prepared by separate consultants and coordinated with the architectural drawings)
- Energy compliance documentation for Step Code compliance
- Material and finish schedules specifying approved products for each area of the home
Why this matters: The quality and completeness of construction documents directly affects the quality of contractor bids and the ease of managing cost changes during construction. Vague or incomplete drawings produce vague bids — and more change orders once work begins.
3D Renderings: What They Are and Why They Help
3D renderings are visual representations of the finished home generated from the design model. They allow clients to review their home from multiple angles — exterior and interior — before any construction begins. This is especially valuable for evaluating:
- Exterior material and colour combinations in context
- Interior space proportions and how natural light will behave
- Kitchen and bathroom layout decisions that are difficult to assess from floor plans alone
- How major finish selections interact with each other
Renderings aren't photographs — they're design tools. The best use of renderings is to identify problems and preferences before they become construction-level decisions.
How East Peak Approaches Design
Our in-house design capability means that design and construction are integrated from the beginning rather than handed off between separate firms. We carry the design intent through construction, which reduces the translation errors that happen when the design team and build team are different organizations working from documents rather than shared understanding.
When you work with us, you see your home in three dimensions before we break ground — and our drawings are built to support construction, not just permit approval.
If you're exploring a custom home build and want to understand what the design process looks like for your specific project, we're happy to walk through it in a free consultation.
