The Architectural Design Process: What to Expect

Over the past five decades, we have walked alongside hundreds of Ontario churches through the architectural design and construction process. One of the questions we hear most often from building committees is simply: what does this process actually look like from start to finish? The answer matters, because understanding each phase — what happens, what decisions you will face, and how long things take — is the single best way to keep your project on track, on budget, and free from costly surprises.

What follows is a detailed walkthrough of the seven phases every church building project moves through, from the very first conversation about needs all the way to the day construction begins. These phases are drawn directly from our project management process — the same framework we use on every engagement. Whether you are planning a new sanctuary, an education wing, a community hall, or a full renovation of an aging facility, the sequence is essentially the same. The scope and complexity will vary, but the discipline of following each phase in order is what separates projects that finish well from those that spiral into delays and cost overruns.

Phase 1: Project Requirements & Needs Analysis

Every project begins with a preliminary meeting between the construction manager, the architect, and the owner — in this case, your church's building committee and pastoral leadership. The purpose of this meeting is straightforward: to listen. We need to understand your ministry vision, your space needs, your congregation's growth trajectory, and the practical constraints you are working within. This is not a sales meeting — it is a working session where we begin to define the scope of the project.

Following that initial conversation, a formal needs analysis is conducted. This involves a thorough assessment of how your current facility is used (or, for a new build, what functions the new facility must serve), how many people each space needs to accommodate, what accessibility requirements exist, and how the building will support your ministry five, ten, and twenty years from now. For renovation projects, we also conduct a building evaluation of the existing facility to assess structural integrity, code compliance under the current Ontario Building Code (OBC), mechanical and electrical system condition, and whether the existing building can support the proposed changes.

At the same time, we investigate the property itself. This includes commissioning a site survey to establish legal boundaries and topography, ordering a geotechnical (soils investigation) report to determine foundation requirements, and researching all municipal constraints — zoning bylaws, required setbacks, easements, and any limitations on the property. In Ontario, church properties sometimes carry special conditions such as heritage or historical designations under the Ontario Heritage Act, which can significantly affect what you are permitted to build and how. We also determine whether the property falls within any environmental protection areas, floodplains, or conservation authority jurisdictions.

The output of this phase is a comprehensive report to the building committee that evaluates the outcome of the needs analysis against the stated project requirements. This report will clearly outline what is feasible on your property, where constraints exist, and whether the project as envisioned can move forward within the anticipated budget range. This is the point where honest, sometimes difficult conversations happen — and that is exactly the point. It is far better to identify limitations now than after you have invested months and tens of thousands of dollars in design.

Phase 2: Schematic Design & Site Plan Development

Once the needs analysis is complete and the building committee has a clear understanding of the project's scope and constraints, the architect begins schematic design. This is where your project starts to take physical shape. The architect develops a site plan layout showing where the building sits on the property, how parking and vehicle circulation work, where pedestrian access points are located, and how the building relates to adjacent properties and roadways. Simultaneously, preliminary floor plans and building elevations are drawn, giving the committee its first real look at how the interior spaces are organized and how the exterior will appear.

If the committee or congregation leadership needs visual aids to support fundraising or congregational approval, renderings can be produced at this stage — three-dimensional illustrations that show what the completed building will look like from various angles. These are not mandatory, but they are extremely effective communication tools. We have seen congregational votes swing decisively when members can actually see what they are being asked to invest in.

This phase involves at least one formal meeting with the building committee to review the drawings, address comments, and work through any revisions. The goal is to reach a general agreement with the owner to proceed with the concept — not final approval of every detail, but a shared understanding that the direction is correct. At this point, a preliminary budget is developed and discussed. This budget is based on current construction costs in your region of Ontario and reflects the scope shown in the schematic drawings. The building committee must agree on this preliminary budget before the project advances, and the owner must formally confirm their intent to proceed. This confirmation is a critical gate — it protects both the church and the professional team from investing further resources into a project that does not have genuine organizational commitment.

Phase 3: Site Plan Application & Municipal Approvals

For most church projects in Ontario, a site plan application (SPA) is required before you can obtain a building permit. This phase is one of the most complex and time-consuming parts of the entire process, and it is where many building committees are caught off guard. The architect prepares the application package, which includes site plan drawings, grading and drainage plans, landscaping plans, and supporting documentation. The application is submitted to the municipality along with the required fees, which are paid by the applicant — your church.

Once submitted, the municipality circulates the application to internal departments (planning, engineering, fire, parks, accessibility) and external agencies (conservation authorities, utility companies, the local ward councillor). A sign is posted on the property indicating that a site plan application has been submitted, which notifies the surrounding community — and occasionally prompts a neighbour to attend a public meeting with concerns that have nothing to do with your project but everything to do with a fence dispute from 1997. After circulation, the city issues a recommendation report containing comments from each reviewing department. These comments will identify required changes to the drawings, additional information needed, and conditions that must be satisfied.

If the project requires a zoning amendment or minor variance — for example, if you need relief from parking requirements, setback distances, building height restrictions, or permitted building use — a separate application process is triggered. This typically begins with a preapplication consultation with the city (which may carry its own fee) and includes a public meeting where neighbouring property owners and community members can voice support or objections. For churches, variance applications most commonly involve parking ratios and setback requirements, and in our experience they are usually resolved favourably provided the application is well-prepared and the church has been a good neighbour.

Following the initial comments, the architect revises the drawings and reports and resubmits them to the municipality. This cycle of resubmission and review will typically happen two to four times before all departments are satisfied. Depending on the municipality's requirements, your project may also need to commission special reports — traffic impact studies, environmental assessments, archaeological assessments (particularly common in older Ontario communities), heritage impact statements, tree preservation or inventory reports, hydrogeological or hydrology studies, stormwater management reports, functional servicing reports, and shadow or shading studies. Each of these reports involves engaging a specialized consultant, adds cost, and takes time.

Once all comments have been addressed and the municipality is satisfied, a draft site plan agreement is prepared by the city's legal department. This agreement is reviewed by both parties and then formally signed by the city and the owner. At this point, cost estimates are prepared for site and landscape letters of credit (LOCs) — financial guarantees the municipality holds to ensure the site work is completed as approved. The architect also prepares site servicing drawings covering underground services (storm, sanitary, water, fire connections), electrical site servicing (underground conduit, transformer pad, site lighting), and detailed landscaping drawings.

Phase 4: Design Development

With the site plan application underway (and often running in parallel), the project enters design development — the phase where every detail of the building is resolved. The architect engages the engineering disciplines required for the project: structural engineering (to design the foundation, steel or wood framing, and load-bearing systems), mechanical engineering (heating, ventilation, air conditioning, and plumbing), electrical engineering (power distribution, lighting, emergency systems), and fire protection engineering (sprinkler design, which is typically required for assembly occupancies under OBC Group A, Division 2). Depending on the project's needs, the owner may also request that sound and acoustical consultants, security system designers, and network or IT infrastructure designers be engaged at this stage.

A design meeting is held with the building committee to review and finalize interior finishes, spatial layouts, and any remaining design questions. The architect develops detailed room schedules (listing every room's function, size, finish materials, and special requirements), door schedules, window schedules, and flooring schedules. Wall sections and construction details are drawn to show exactly how the building envelope, insulation, vapour barriers, and cladding systems come together — these details are critical for achieving the energy performance requirements of the current OBC and Supplementary Standard SB-10.

The most important work happening in this phase is the coordination of all engineering and architectural drawings. The structural engineer's foundation plan must align with the architect's floor plan. The mechanical engineer's ductwork routing must not conflict with the structural steel. The electrical engineer's panel locations must be accessible and code-compliant. This coordination exercise is painstaking but essential — think of it as the engineering equivalent of making sure the worship team, the Sunday school, and the ladies' brunch are not all booked into the fellowship hall on the same Saturday. Conflicts discovered during construction are exponentially more expensive to resolve than conflicts caught on paper. A final design review meeting is held with the building committee before the project advances to permit drawings, ensuring that the owner is fully satisfied with every aspect of the design.

Phase 5: Building Permit

With the design fully developed and approved by the building committee, the architect prepares a complete set of drawings and specifications for the building permit application. These drawings must demonstrate compliance with the Ontario Building Code in every respect — structural adequacy, fire safety, accessibility (including AODA requirements), energy efficiency, plumbing, HVAC, electrical, and life safety systems. For a church classified as Group A, Division 2 (assembly occupancy), the OBC imposes specific requirements around occupant load calculations, exiting, fire separations, sprinkler coverage, and emergency lighting that differ from other building types.

The building permit application is submitted to the municipality along with the required application fee, which is paid by the owner. The fee is typically calculated based on the project's construction value and can be substantial for larger projects — often in the range of several thousand to tens of thousands of dollars. The municipality assigns the application for review and circulates the drawings to internal departments (building, fire, planning, accessibility) and sometimes to external agencies.

After review, the city issues comments identifying any areas where the drawings do not satisfy code requirements or where additional information is needed. The architect addresses these comments, revises the drawings as necessary, and resubmits them for further review. As with the site plan application, this cycle typically requires two to three rounds of resubmission before the permit is issued. The building committee should expect the permit review process to take anywhere from six weeks to four months depending on the municipality, the complexity of the project, and the current volume of applications in the building department's queue.

Phase 6: Contract Documents & Tendering

Once the building permit is in hand (or near approval), the project team shifts its focus to contract documents and tendering — the process of turning a permitted design into a priced, contracted construction project. The architect and construction manager finalize the complete set of contract documents, which include the full architectural and engineering drawings, project specifications, general conditions of the contract, and supplementary conditions specific to this project.

The construction manager develops a detailed subcontractor and vendor list, identifying qualified trades for every scope of work — excavation, concrete, structural steel, framing, roofing, cladding, mechanical, electrical, fire protection, drywall, flooring, painting, millwork, and all specialty trades. A detailed budget is prepared based on quantity take-offs from the contract drawings, and a project schedule is developed showing the sequencing and duration of every phase of construction. Invitations to bid are sent to the selected subcontractors along with the complete drawing package and bid instructions.

During the tendering period, subcontractors will submit questions about the drawings and specifications. The construction manager coordinates with the architect to respond to these questions, issuing addendums as required to clarify or revise the documents. Once bids are received, the construction manager prepares contract comparisons — detailed analyses that evaluate each trade's pricing, scope inclusions and exclusions, and qualifications. This analysis is reviewed with the building committee so they can make informed decisions about trade selection. Engineering locates are ordered to identify all underground utilities on the site before excavation begins. Contracts are signed with the selected trades, and all outstanding municipal fees and letters of credit are paid as outlined in the site plan agreement.

Phase 7: Construction Begins

With contracts signed and the site ready, construction mobilization begins. The contractor establishes the construction site by installing perimeter fencing and safety hoarding, setting up the site entrance for construction vehicles, placing the site trailer and portable washroom facilities, and arranging temporary hydro and telephone service. Accounts are established with utility providers for the construction period. These setup activities typically take one to two weeks before actual ground-breaking work begins.

Before construction work commences, a formal budget and coordination meeting is held with the building committee. This meeting reviews the final construction budget, the project schedule with key milestones, the communication protocol for the construction period (how often the committee will receive updates, who their primary contact is, how site visits will be managed), and any outstanding items that require owner decisions. If any redesign is required to address late-stage comments from the municipality or changes requested by the building committee, those revisions are resolved before construction proceeds.

From this point forward, the construction manager oversees every aspect of the build — coordinating trades, managing the schedule, conducting quality inspections, processing progress draws, and keeping the building committee informed at every step. Regular site meetings and progress reports ensure that the committee always knows where the project stands relative to the budget and timeline. The construction phase for a typical church project in Ontario ranges from eight to eighteen months depending on the size and complexity of the work, site conditions, and weather.

"Do not underestimate the value of the preconstruction phases. The time invested in thorough needs analysis, careful design development, complete municipal approvals, and disciplined tendering is what makes the construction phase go smoothly."

Bringing It All Together

The architectural design process for a church building project is not a single event — it is a carefully sequenced series of phases, each building on the one before it. From the initial needs analysis through schematic design, municipal approvals, design development, permitting, tendering, and finally construction, the process typically spans two to four years. That timeline can feel daunting, but each phase serves a clear purpose: to reduce risk, control costs, and ensure that the building your congregation occupies is exactly the building they envisioned.

The single most important thing a building committee can do is engage experienced professionals early — before the first drawing is produced. A construction manager who understands church projects, Ontario building codes, and municipal approval processes can guide your building committee through each phase with confidence, helping you avoid costly mistakes and keeping your project on track and on budget.
