Schematic design is the first phase of an architectural project, where an architect and building owner work together to establish the overall vision, layout, and scale of a building before any detailed engineering or construction planning begins. Think of it as the “big picture” stage: the goal is to answer fundamental questions about what the building will look like, how spaces relate to each other, and whether the project is feasible within the site, the budget, and local regulations.
What Happens During Schematic Design
The phase starts with conversations between the architect and the owner to define the project’s goals and requirements. This process produces what’s called an architectural program: essentially a written outline of every function the building needs to serve, along with estimated square footage for each type of space. A medical office, for example, might need exam rooms, a waiting area, administrative offices, and storage, each with a target size.
Once the program is established, the architect begins creating study drawings and visual materials that illustrate the design concept. These aren’t construction-ready blueprints. They’re exploratory documents meant to show spatial relationships, overall form, and scale so the owner can react, ask questions, and request changes early, when changes are cheap and easy to make.
Schematic design also doubles as a research phase. The architect investigates zoning requirements, building codes, and any jurisdictional restrictions that could affect what’s allowed on the site. Discovering these constraints early prevents expensive surprises later. By the end of the phase, the architect produces a final schematic design that the owner formally agrees to before the project moves forward.
Typical Deliverables
The documents produced during schematic design give the owner (and the rest of the project team) enough visual and dimensional information to understand the design intent without getting into construction-level detail. A standard set of deliverables includes:
- Site plan: Shows the building’s location on the property along with roads, parking areas, and landscape elements.
- Floor plans: Layouts of every level showing the structural grid, stairs and elevators, interior walls, and door and window locations.
- Roof plan: The shape and slope of the roof as seen from above.
- Building sections: Vertical “slices” through the building that reveal floor-to-floor heights, ceiling conditions, and how spaces stack on top of each other.
- Building elevations: Flat views of each exterior face, showing the look of the facade.
- Conceptual details: Typical wall sections or other close-ups that hint at how major assemblies will be constructed.
Architects often supplement these drawings with 3D computer renderings, physical models, or animations to help owners who aren’t used to reading architectural plans. Overall dimensions are typically included, and the architect produces a preliminary construction cost estimate so the owner can gauge whether the design fits the budget.
How It Differs From Later Design Phases
Architectural projects generally follow a sequence: schematic design, then design development, then construction documents. Each phase adds a layer of detail and precision.
During schematic design, the drawings are conceptual. A floor plan might show room sizes and general wall locations, but it won’t specify what the walls are made of, where electrical outlets go, or how plumbing is routed. Design development takes the approved schematic and fills in those specifics: materials, finishes, mechanical systems, and structural details. Construction documents then translate everything into the precise, dimensioned instructions a contractor needs to actually build.
The reason schematic design stays intentionally loose is flexibility. If the owner realizes during this phase that they need a larger lobby or a different building orientation, the architect can adjust quickly. Once the project moves into design development, changes become progressively more expensive and time-consuming because so many other decisions are already built on top of the earlier ones.
The Owner’s Role
If you’re a building owner or project manager entering schematic design, your job is to communicate your priorities clearly and give meaningful feedback on what the architect presents. The architect needs to understand not just what rooms you want, but how you plan to use them, how many people will occupy the building, what your growth plans look like, and what your budget constraints are.
This is the phase where your input has the most leverage. Every decision made here, from the building’s footprint on the site to its number of stories, shapes every phase that follows. Rushing through schematic design or withholding key information (like a firm budget ceiling) tends to cause problems downstream when the design has to be reworked at greater cost.
Software and Tools
Architects today use a combination of hand sketching and digital tools during schematic design. Software like Revit and AutoCAD allows quick generation and modification of both 2D sketches and 3D models. Newer tools focused on early-stage design, such as Autodesk’s Forma, let architects generate quick massing models they can test and iterate on, including running early analyses for things like solar exposure and environmental impact. These tools speed up the feedback cycle by making it easy to produce multiple design options for the owner to compare, rather than committing to a single direction from the start.
How Long Schematic Design Takes
Duration varies widely based on project size and complexity. A straightforward single-story commercial building might wrap up schematic design in four to six weeks. A large institutional project, like a hospital or university building, could spend several months in this phase as multiple stakeholders weigh in and the architect works through several rounds of revisions. Projects with complicated zoning issues or unusual site conditions also tend to extend the timeline, since the research component of schematic design takes longer.
Regardless of project size, the phase ends at a clear milestone: the owner reviews the final schematic design, confirms it meets their goals and requirements, and gives approval to proceed into design development.
