Making sure you’re happy with everything at this crucial design phase
If you’re preparing to build a new home or undertake a major renovation, the final stages of the architectural design process are where everything begins to come together. For anyone working with architects in Belfast, this phase is crucial. It brings the design to life and sets the foundation for a smooth construction journey. At this stage, decisions are final. Documentation is complete. We also begin working closely with contractors.
At McCann Moore Architects, we guide our clients through this detailed and important step with precision, ensuring every element is ready before the first brick is laid. A well-managed final design phase prevents miscommunication, reduces the risk of costly errors on-site, and creates the confidence needed to move forward with construction.
Finalising architectural drawings and specifications
By the time a project reaches this stage, the overall design has been established. The focus now shifts to refining every detail. This includes:
- Floor plans and internal layouts
- Elevations and structural details
- Lighting, plumbing, and electrical layouts
Our team of architects ensure these documents are both technically accurate and clearly presented. This clarity is vital for builders and contractors to interpret and execute the design without ambiguity. We also conduct cross-discipline reviews to check coordination between architectural, structural, and mechanical plans, avoiding issues on-site.
Avoiding last-minute material and finish decisions
Choosing finishes is often one of the most exciting parts of the design process, but it also carries significant budget and timeline implications. At McCann Moore, we work closely with clients to confirm selections such as:
- Flooring materials
- Sanitary ware and fittings
- Window and door specifications
- External finishes (brick, render, cladding)
We provide mood boards and samples where needed, along with guidance on performance, sustainability, and cost. Early decisions prevent delays and reduce the risk of budget creep. Suppliers often require long lead times, so finalising these choices now helps secure better pricing and availability, while ensuring everything arrives on-site when needed.
Submitting designs for final planning and building control approval
One of our key responsibilities is managing local planning and building control requirements. Once designs are locked in, we:
- Submit updated drawings to Belfast City Council for planning sign-off (if needed).
- Handle building control submissions, ensuring all safety, accessibility, and energy efficiency requirements are met.
Building control approval covers structural safety, energy performance, accessibility, ventilation, and fire protection. Our experience ensures these submissions are thorough and aligned with local expectations.
Delays in approvals can push back start dates significantly. Our proactive approach helps clients avoid common pitfalls, such as incomplete documentation or failure to meet technical standards.
Tendering and selecting the right contractor
Finding the right builder is about more than just price. As your architectural partner, McCann Moore:
- Issues them to a select list of vetted contractors
- Prepares detailed tender packages
- Assists in evaluating bids based on value, experience, references, and programme
We don’t just look at the lowest price. Our goal is to ensure you’re working with a contractor who understands your project, respects the design, and has a proven track record. We support our clients in contract negotiation and ensure all parties are aligned before signing.
Creating a construction timeline and budget review
With a contractor in place, we help establish a realistic programme and budget. This step involves:
- Agreeing a timeline with key milestones
- Reviewing updated quotes from suppliers and subcontractors
- Checking contingency allocations and allowances
We advise on contingency allowances and help our clients understand how decisions made at this stage can affect cost outcomes. Having a clear timeline and financial plan creates transparency and trust among all parties.
The role of an architect in construction
Even when drawings are finalised and builders are on-site, the architect’s role continues. We’re involved in:
- Site visits to check work aligns with the design
- Addressing contractor queries
- Reviewing materials and workmanship quality
Our involvement protects the integrity of the design, ensures materials and workmanship meet the agreed standards, and helps resolve unforeseen issues efficiently. We often chair site meetings and coordinate updates to keep clients informed.
Case Study: A Smooth Transition from Design to Construction
A recent McCann Moore project in South Belfast illustrates the value of this process. The client, undertaking a large contemporary extension to a Victorian terrace, needed detailed planning input due to conservation requirements and tight site constraints.
We managed final design approvals, coordinated with structural engineers, and prepared an accurate tender package. This allowed the client to appoint a builder with confidence. Because all decisions and materials were finalised in advance, the build progressed smoothly with no major delays or cost overruns.
The result? A beautifully finished space delivered on time and within budget, and a client who praised the clarity and professionalism of our process.

FAQs – Final architectural design and pre-construction process
How long does the final design phase take before construction?
Typically 4–8 weeks, depending on project complexity, planning conditions, and contractor availability.
What happens if I change my mind after finalising the design?
Changes are possible, but they may impact cost, schedule, and planning approvals. We advise clients to finalise all decisions before tender.
Do architects stay involved once construction begins?
Yes. At McCann Moore, we offer contract administration services to oversee quality and ensure the build remains true to the design intent.
