Our Team
Ciaran Mullin
Founder and Registered Builder
I'm Ciaran, a qualified carpenter, registered builder, and the founder of Add Value Building Group. Originally from Ireland, I moved to Perth in 2011. Building is in my blood, my dad was a residential builder, and I’ve been tagging along on job sites since I could walk.
From as far back as I can remember, I always knew I wanted to run my own building company. In 2014, I started Add Value Building Group to create a business that prioritises honest communication, quality workmanship, and genuine care for the people we build for. My strength lies in clear, effective communication, having a can-do attitude and understanding that for many of our clients, this is the biggest investment of their lives, something I never take lightly.
Today, I live in Mount Hawthorn with my partner Dee, our daughter Ava, stepson Cooper, and Frank the dog. I love spending time with my family, since Ava has been born, I have been fortunate to have a good work life balance. To stay mentally and physically fit, I do CrossFit a few times a week and am currently working on improving my swimming.
William Larrington
Junior Site Supervisor
Born and raised in Perth, William has grown up around construction, with his family regularly renovating homes. That early exposure sparked a lasting passion for building, property, and the creative problem-solving that comes with it.
During high school, William was awarded a scholarship to complete a pre-apprenticeship in plumbing and gas fitting, giving him hands-on industry experience early on. After graduating, he moved straight into the workforce and quickly progressed to a leading-hand role at a large building company, gaining strong practical knowledge across residential construction.
William is currently working towards his Bachelor of Property Development and Valuation at Curtin University, combining practical trade experience with technical skills in property analysis and development. Detail-driven by nature, he thrives on tackling challenges, solving problems, and ensuring quality outcomes in every project.
Outside of work, William maintains a healthy and balanced lifestyle. He enjoys taking his dogs to the beach, staying active at the gym, and making the most of Perth’s outdoors
Kris Caling
Project Manager
Kris Caling has a background in civil engineering and holds a CAPM from the Project Management Institute, as well as a MPM from the University of Sydney. With a strong foundation in project delivery and construction management, Kris is a whizz at project management and project administration.
At Add Value Building Group, Kris values the team’s professionalism and the genuine commitment of its director, Ciaran, to helping homeowners and future homeowners build with confidence. Ciaran’s leadership and dedication to client satisfaction make AVBG a great place to grow and contribute.
She is passionate about delivering a smooth customer experience, underpinned by clear and transparent communication at every stage. Transparency, accountability, and collaboration are among the core values that guide her work.
Outside of construction, Kris loves to travel and once explored 10 countries in a single month with just a 7kg backpack, firmly proving she’s not a fan of excess baggage, on or off the job.
Joyce Sedano
Administration
Joyce brings over 17 years of experience in construction administration, supporting project teams and streamlining operations. Her understanding of the construction process and behind-the-scenes coordination makes her an integral part of the Add Value Building Group team.
She was drawn to AVBG’s vision of building homes that reflect each family’s lifestyle, values, and what matters most to them. Joyce is also inspired by the company’s ambition for broader impact and its commitment to meaningful, client-focused work.
In her role, Joyce ensures that the operations team is fully supported with all administrative needs, freeing them up to focus on execution and on-site delivery. Her strengths lie in organisation and anticipating the needs of both the team and clients to keep everything running smoothly.
Family is at the heart of everything Joyce does, and she values integrity, teamwork, and consistency in both life and work. During her time off, you’ll find her enjoying simple moments with her children and partner, whether relaxing at home or spending time outdoors together.
Frank.
Office Manager / Security / Support Officer
Frank joined the team in 2021 and was originally hired because his coat perfectly matched our branding, a purely aesthetic decision, if we're honest. But it didn’t take long to discover he brought more than just good looks and impeccable markings to the role.
Within weeks, Frank was promoted to Support Animal, providing morale boosts, lunchtime entertainment, and the occasional cuddle. As his confidence grew, so did his responsibilities, stepping up as Security Guard, complete with a loud bark and zero tolerance for couriers, leaves blowing or anything that moves or breaths outside of the doors.
Today, Frank holds a dynamic, multi-skilled role, expertly balancing snoozing under desks with spontaneous ball-catching demonstrations.
He enjoys long naps, snacks, and short walks (preferably nowhere near a moving vehicle, he’s not a fan of the car). So, while you won’t find him out on site, he’s always available at HQ for a back scruff.
Extended team of trusted partners and sub-contractors
We are fortunate to have a large pool of local trusted consultants, contractors and suppliers who work with us daily, most of whom have worked with us since 2014. Which we are grateful for their ongoing support.
