About Us
Your Project Journey
Working across the UK and Ireland, we follow the RIBA and RIAI 8-stage framework to guide projects from concept to completion. In practice, most of our work falls into six key stages — from early design and planning through to detailed development and construction. We offer full architectural services or selected stages structured, flexible, and tailored to you clients’ needs. Our process brings clarity, creativity, and confidence at every step.
Consultation & Briefing
At Rejen Architects, we begin every project with an in-depth consultation to fully understand your vision, goals, and challenges. Through collaborative discussions, we ensure that our purpose aligns with your aspirations for the project. Whether it’s a heritage restoration or a contemporary new-build, this stage is about uncovering the unique potential of your project and setting the foundation for its success.
Feasibility & Concept Design
The next step is to explore the possibilities of your project. We identify early challenges and recommend necessary surveys. Through initial concept and strategic-level design explorations, we scope out project options and collaborate with you to establish the general design direction. This stage is crucial for refining the project’s scope and ensuring clarity before moving forward.
Planning & Approvals
We handle the complexities of securing planning and listed building consents. This includes developing detailed design proposals, consulting with community stakeholders, and engaging statutory and historic building authorities to address specific challenges. Our expertise ensures a smooth application process and successful outcomes that align with your goals.
Detailed Design
At this stage, we prepare comprehensive design packs, including construction drawings and specifications, while coordinating inputs from other consultants. We manage building control or BCAR submissions, assist in contractor selection, prepare tender documents, review tender returns, and align project costs with your budget. Throughout the process, we work closely with the project cost consultant to manage risks and unforeseens, monitor the project scope, programme, and budget against the initial agreed brief, and seek client approval at the end of each stage before moving to the next.
Delivery
Rejen oversees the construction phase with a commitment to maintaining design excellence and delivering your project on time and within budget. We handle contract administration, resolve contractor queries, chair site progress meetings, and manage follow-up actions to ensure a smooth build. We also manage building control approvals, oversee commissioning and handover, and certify practical completion, ensuring your project is delivered to the highest standards and ready for its intended use. Our proactive approach ensures the vision established at the outset becomes a reality with precision and care.
Handover & Completion
We guide you through the final stages to ensure your project is delivered to the highest standard. We carry out detailed inspections, coordinate snagging works, and work closely with the contractor to resolve any outstanding issues. Our goal is to hand over a building that not only meets but exceeds your expectations — a place where your vision is fully realised, ready to be enjoyed and celebrated.
The Studio
Our mission is to breathe new life into old buildings, creating environments that are inspiring, elegant, and enduring, and doing so with integrity, collaboration, and a commitment to excellence.
We believe that the best work happens when it is driven by creativity, ambition, and enjoyment. We take pride in what we do, and we enjoy the process, working alongside creative, forward-thinking clients who share our vision. This energy and passion not only fuel our team but are also valued by those we work with, making each project a rewarding journey.
From boutique hospitality to workplace, residential, and cultural projects, we collaborate with clients who see the value in thoughtful, meaningful architecture that respects the past while shaping the future.
Our journey is just beginning, but our vision is clear: to grow Rejen into a leading practice that delivers exceptional, purposeful architecture, and to play our part in making the built environment healthier, more vibrant, and more sustainable by reimagining, repurposing, and regenerating buildings and places.
Our Belfast studio is located on Hill Street in the heart of the city’s historic and vibrant Cathedral Quarter — a cultural hub known for its creativity, independent spirit, and thriving arts scene. Surrounded by listed warehouses, galleries, and some of Belfast’s best hospitality venues, it’s a fitting base for a practice dedicated to breathing new life into old buildings and places. In 2025, we established a shared workspace presence in Dublin on Harcourt Street — a prime location in the heart of the capital, close to many of our clients and collaborators. This new foothold allows us to work more closely with development teams across Ireland and support our growing portfolio of projects in the region.
The Team
Rejen Architects is led by Founder and Managing Director Rob Jennings. Our core team is based in our Hill Street Belfast studio, while Rob splits his time between Belfast and Dublin to support projects across the island. We are supported by a trusted network of external consultants and our collaborations with both local and London-based architecture practices – enabling us to scale and tailor our teams to meet the specific needs of each project.
We’re always keen to connect with exceptional individuals who share our passion for transformative design that prioritises people, places, and the planet. If that resonates with you, we’d love to hear from you – please reach out to us on email below or the website contact page.
