Belfast Architects: A Step-by-Step Guide from Design to Completion

Why Work with Belfast Architects?

Planning a home extension or renovation is an exciting journey, but it comes with its challenges. You might have a vision for a larger kitchen, an extra bedroom, or a modernised living space, but turning that idea into reality requires careful planning and expert guidance. This is where our Belfast architects at, McCann Moore Architects, come in.

As experienced architects in Belfast, we bring creativity, technical expertise, and project management skills to guide your project from the first sketch to the final brick. Many homeowners ask whether they need an architect or if a builder alone can complete the job. Think of us as planners and creative problem-solvers—we ensure your project is structurally sound, functional, and aesthetically exceptional.

Beyond design, we handle all the necessary paperwork and legalities, from securing planning permission to ensuring compliance with building regulations. We coordinate with engineers, surveyors, and builders, giving you peace of mind.

“Contacting Seán and Paul at McCann Moore Architects about our renovation and extension project was the best decision we made. First and foremost, they delivered 100% on the design brief. We loved their design and, from the moment we saw it, it was clear that they understood exactly what we wanted. They treated our budget like it was their own and included innovative & stylish finishing touches whilst being mindful of material costs. We really appreciated this sensibility.” – Jason Stewart .

This guide will walk you through our architectural process, from the initial consultation to project completion, ensuring your project runs smoothly and efficiently with the expertise of our Belfast architects.

Step 1: Initial Consultation – Understanding Your Needs

We begin by listening. Whether you have a clear vision or just a rough idea, our first conversation helps us understand what matters most to you. We’ll discuss:

Your Goals – Do you need more space, a better layout, or improved lighting?
Your Budget – A realistic budget allows us to tailor the design accordingly.
Your Timeline – Do you need the project completed by a specific date?
Your Style Preferences – Modern, traditional, minimalist? Sharing reference images helps.
Existing Challenges – Issues such as poor layout or lack of light should be highlighted.

During this meeting, we outline our process and may even sketch rough ideas to illustrate possibilities. As experienced Belfast architects, we understand the unique challenges of properties in the city and suburbs. For example, if you live in a Belfast terrace house and want a kitchen extension, we might suggest a side-return extension to maximise space without sacrificing your garden.

Following the consultation, we provide a written proposal outlining our services, fees, and next steps. Once you approve this, we move into the design phase.

Step 2: Concept Design – Bringing Your Vision to Life

With a clear brief in hand, our Belfast architects begin drafting design concepts. This stage transforms your ideas into initial sketches or 3D models, helping you visualise the space.

At this stage, we:

Assess the existing property layout, natural light, and site constraints.
Create initial design options, often presenting two or three variations.
Hold a follow-up meeting to refine and develop the preferred concept.

For example, if you want a bright kitchen extension but also need space for a dining area, we can adjust the layout to balance practicality and aesthetics.

Once the concept design is finalised, we move towards permissions and technical planning.

Step 3: Planning Permission & Regulations

Depending on the scope of work, planning permission may be required. We manage this process by preparing and submitting drawings to the local council.

Key aspects of this stage include:

Permitted Development vs. Full Planning Permission – Some projects fall under permitted development, meaning no formal application is needed. We assess this for you.
Application Process – The council reviews submissions over 8-12 weeks and may request adjustments.
Building Regulations Compliance – Ensuring structural safety, insulation, fire safety, and ventilation meet the required standards.

With our expertise in planning policies and negotiations, we ensure a smoother and more efficient approval process.

Step 4: Detailed Design & Technical Drawings

Once permissions are secured, we refine the design into technical drawings that builders will use. These include:

Structural details (e.g., foundations, insulation, steel beams)
Electrical and plumbing layouts
Specifications for materials and finishes

At this stage, we may bring in a structural engineer to confirm load-bearing elements. Detailed plans also ensure accurate contractor pricing, preventing unexpected costs later in the project.

Step 5: Choosing a Contractor & Getting Quotes

With the technical drawings finalised, it’s time to find a builder. We assist by:

Tendering – Sending plans to multiple contractors for pricing.
Quote Comparison – Reviewing costs, timelines, and scope.
Contract Selection – Choosing a reliable contractor based on experience, budget, and communication.
Formal Agreement – Setting terms for payments, timelines, and responsibilities.

A well-structured contract protects you from delays and unexpected expenses, ensuring a smoother build process.

Step 6: Construction Phase – Overseeing the Build

Once construction begins, our Belfast architects remain involved to oversee progress and ensure the build aligns with the approved plans.

Our role includes:

Site Visits – Regular inspections to check quality and resolve issues.
Managing Changes – Addressing unforeseen challenges, such as structural surprises.
Communication – Acting as a liaison between you and the builders to keep the project on track.

We work to minimise disruptions and keep your project running smoothly from start to finish.

Step 7: Project Completion & Final Touches

As construction wraps up, we conduct final checks to ensure everything meets expectations.

Key steps include:

Snagging List – Identifying and addressing small fixes before handover.
Building Control Sign-Off – Ensuring regulatory compliance.
Final Walkthrough – Reviewing the space with you and the builder.
Handover Documentation – Providing certificates, warranties, and maintenance guidance.

Our support doesn’t necessarily end here—we can also advise on styling, furniture placement, or even future projects.

Common Pitfalls in Renovations & Extensions (And How We Solve Them)

Ignoring Natural Light – Many homeowners focus solely on floor space and forget about how natural light will enter the new area. A poorly lit extension can feel cramped and uninviting. We carefully analyse sun paths and use design techniques like skylights, glass doors, or strategically placed windows to enhance brightness.
Overlooking Storage Needs – An open-plan extension might look sleek in initial designs, but failing to include sufficient storage can lead to cluttered spaces. We integrate smart storage solutions within the design, such as built-in cabinetry or multi-functional furniture, to maintain a clean and practical layout.
Underestimating Costs – Many projects go over budget due to unforeseen expenses. Our role as architects is to provide a realistic cost breakdown and work with you to ensure financial planning is as accurate as possible. We also recommend cost-effective materials and finishes that align with your budget without compromising quality.
Planning Permission Delays – Incorrect or incomplete applications can cause frustrating setbacks. We handle all planning applications, ensuring compliance with local council regulations, and provide solutions if additional approvals are required.
Disruptions During Construction – Many homeowners worry about prolonged construction and unexpected disruptions. We work closely with contractors to establish a clear timeline, conduct regular site visits, and swiftly address any challenges that arise, keeping your project on track.

By proactively addressing these challenges, we work to minimise disruptions and keep your project running smoothly from start to finish.
