Schematic design is essentially the phase of construction planning and design where project teams aim at arriving at a shape, form, and layout of the construction plan before the final design locks in. This leads to establishing a more structured construction design process that provides a better scope of collaboration, improved clarity, and enhanced quality in achieving optimum design workflows and project output.
Schematic design focuses on identifying technical flaws and procedural gaps and eliminating any existing discrepancies or possible clashes early to ensure the final output is free of errors and is as per the design intent and domain standards.
Schematic design plays an imperative role in shaping the project's identity by creating the fundamental construction plan and design framework. Through schematic designs, architects perform site analysis as per the owner's program and budget.
Schematic design offers a complete visual direction for approaching the right building design that includes site plans, floor plans, and elevations to establish design workflows that best serve the architectural scope and functional requirements of the building systems.
Through schematic designs, project teams produce building illustrations and schemes for both exterior designs and interior spaces. This takes into account the architectural plans across project design phases, serving various technical requirements as per the project scope and proposed building codes.
The underlying purpose of the schematic design is to put the design concepts into buildable schemes that are aligned with the development scope, functional requirements, and sustainability strategies of the project.
Construction professionals follow a standardized process of design that is built on a sequential approach, entailing different design phases. Here, schematic design precedes all the design phases, building an operational foundation of the construction design and documentation process, entailing different design phases. Here, schematic design precedes all the design phases, building an operational foundation of the construction design and documentation process.
Working on schematic designs (SD), the architects focus on preparing early drawings of the building to conceptualize and define the fundamental design scope, program directives, architectural scheme, construction workflows, and control strategies of the project from conception.
In the schematic design phase, architects aim to prepare the fundamental drawings and illustrations to define basic form, scale, layout, and spatial relationships between functional components and procedural flows.
This paves the critical ground for the design development (DD) stage, where the approved schematics form the fundamental reference point for material selection, system coordination, and cost estimation.
This entire approach further makes way for construction documents (CD) that are essential for any project to cohesively create building drawings and spec sheets and fulfill compliance to help with permits, procurements, and pricing.
With this, the architects extend support to the project owners and managers to get accurate pricing from contractors and vendors and verify bids to assure optimum outcomes.
Eventually, schematic designs go through the process to take a firm shape to contribute to the construction administration practices where architects support the build, provide solutions to site queries, review submittals, and help validate if the final output is aligned with the design intent.
The common job roles that are integral to schematic design include professionals with pro-domain expertise and typically include architects and project managers for the most part of the job. Other domain professionals and SMEs play assistive or additional roles.
Listed below are some of the job roles that are common to the schematic design phase.

Schematic design includes basic project drawings and documents. These depict the overall design workflow, construction scale, layout specifications, and system details at the basic architectural design level. The project architects work on visual plans, technical notes, site components, and structural details to provide the necessary conceptual base and schematic support guiding later phases of the architectural design process.
Architectural drawings include fundamental plans for the site layout, floors, structural elevation, spatial references aligned with the project design scope, operational timelines, and value parameters. This provides a comprehensive and detailed picture of how the built facility will be connected through the structural flow and support the functional systems across the site plan.
Architects work on the early technical notes of the structural systems, including electrical, plumbing, HVAC, and different connected functional utilities that are to be sourced and implemented in the final design in the later stages. These act as tentative system specs and provisional details that just build the initial reference framework for the building's architectural design process.
Architectural visual representation may include digital models, physical models, or perspective sketches that provide a schematic preview of the building for project stakeholders to get detailed insights and extensive understanding of the architectural design application and execution plan. These are not construction-ready visuals and provide a preliminary design overview and early directive inputs.
The Schematic Design process is a structured way for architects to process ideas into action and ensure timely execution across phases. The schematic design stage connects all the stakeholders and professionals from the client side and the provider side to facilitate coordination, enhance decision-making, and ensure production efficiency across the process.
Mentioned below are the steps that depict the common approach followed for the schematic design process:
It all starts with the preliminary analysis. The principal architect goes through the design brief and makes inferences out of it to concretely define the design problem or requirement. This step focuses on the project's design objectives, value compliances, site conditions, operational constraints, and building code frameworks.
This is the step where the core design ideas are explored through critical design thinking and concept corroboration. The architects build magnified ideas about the building's physical form, system workflow, and spatial relationships. These could be in the form of gross sketches, massing studies, or digital illustrations, depending on the approach and requirements. In some projects, this step may be replaced by 'concept design'; however, in some cases, it may be executed and signed off before the schematic work begins. In any of the situations, the underlying goal is to validate the design idea and follow the optimum execution plan.
Once the direction is clear, the architect is able to get into action and update and refine the layout design further. They critically test the workflow, work on spatial details, adjust massing, and optimize layout schemes to ensure the design is as per the conceptual intent and guiding standards. The designs may go through a number of iterations to achieve optimum mark of quality meeting standard compliance across the course of execution.
The team gathers all the information together and puts it in a consolidated document that includes every detail about the project around the work scope, approach, execution plan, milestones, visual component, architectural notes, and core project specs. These documents typically focus on presenting the site plans and drawings and sometimes take into account 3D visuals based on the project's requirements. Once these are created, they require expert reviews and approvals on procedural practices, implementation costs, and design frameworks, before they are considered good to go further for the design development phase and consequently enter the later stages of the process.
It is not realistic for any process to always go as planned and for a practice like Schematic Design there are chances that it may get disturbed or derailed due to various process deviations and mistakes. These could be because of unclear project goals, rushed approach, or wrong decisions.
Let's explore the common mistakes that may adversely impact the schematic design process and result in detrimental delays, hefty reworks, and budget blowouts in due course.
With vaguely defined project scopes and unclear objectives, design concepts may face a massive drift. As most things are done without set priorities and proper directions, the resulting output may deviate, causing process breakdowns and cost overruns.
Action: Project stakeholders and executives should work together to identify and set up clear objectives, preparing lists of must-dos, top-priorities, and non-negotiables before entering the schematic design phase.
Schematic Designs may seem unready or half-cooked for cost-related design decisions. However, in the real-world scenario, it all starts by testing workflow planning, structural integrity, and system finishes for cost factors in the first place. If costs are not tracked early in time, it may result in serious budget failures.
Action: Quantity surveyors should be brought in early into the review processes. With schematic-level cost checks happening upfront in the early design phase, it reduces the chances of budget misalignment.
If the key stakeholders of the project who are on top of the functional hierarchy and are in the decisive position do not participate or review project activity or resulting output for long, it may negatively impact the overall value metrics.
Action: Involve CXOs along with the departmental heads of finance, IT, Operations, and Compliance in document review to catch the flaws and gaps early. This may result in a pertinent and perceptive check with their domain expertise and vision aligned with the project objective.
Schematic design is one of the fundamental practices of the construction planning process for ensuring architectural design consistency and accuracy in the system. By detecting any existing flaws and possible deviations early in the building's architectural layout plan and structure, architects get to fix them in time by referring to the details of the schematic design phase. This ensures a cohesive and detailed representation of the design plan to form a concrete base for further construction design phases, contributing to better design decisions, controlled costs, enhanced value collaboration, and higher efficiency down the line.
The schematic design is the one that defines the fundamental concept and the design development elaborates materials, systems, and layouts. DD makes structure, functionality, and specifications more complete; thus the project is technically and visually more defined.
Upon approval, the project proceeds to design development. Architects create more elaborate drawings, develop materials, define systems, and work with engineers. Cost estimates and constructability reviews also progress to ensure alignment with project goals.
Construction documents are very detailed drawings and specifications that contractors use to construct the project. These essentially include structural sheets, mechanical details, schedules, dimensions, and notes that state materials, assemblies, and installation requirements in detail.
Each stage is a continuation of the previous one. SD discusses concepts, DD makes them technically clear, and CD writes specifications to be followed in constructing. They collectively mitigate risk, manage cost and facilitate a seamless process of development up to completion.
Yes, it is possible to make adjustments in later stages, but the closer the project is to completion the more expensive and disruptive are any changes. Early finalization of decisions ensures that the timeline remains stable and that the redesigning is minimized during development or documentation.
Clients are usually provided with conceptual floor plans, simple elevations, 3D images, and an approximate initial cost. Such documents demonstrate the appearance and functionality of the building, which is sufficient to grant the design approval prior to proceeding.
