About Us

We’re Adam and Cass — the founders of Lummy & Co.

Lummy & Co is a Central Coast NSW based construction business specialising in quality renovations and residential builds. With over a decade of industry experience, we take a practical, considered approach to every project, focusing on clear processes, strong workmanship, and the details that matter. Our goal is simple: transforming houses into homes.

We believe a home should feel lived in, connected, and deeply personal. That’s why we put care into every detail, creating spaces that not only look beautiful, but function effortlessly for everyday life.

Specialising in renovations, extensions, new builds and second-storey additions across the Central Coast and Lake Macquarie NSW, we collaborate closely with our clients to bring thoughtful, functional homes to life balancing practicality, craftsmanship, and timeless design in every project.

As a licensed and insured residential builder, we’re committed to delivering high-quality spaces designed to be lived in and loved for years to come.

Our Process

We believe a smooth and successful project starts with clear communication, thoughtful planning, and complete transparency from the very beginning. Our process is designed to give clients confidence and clarity at every stage, with regular updates, open communication, and a collaborative approach throughout the entire journey.

From initial consultation through to final handover, we operate as one coordinated team. Being well connected in the industry is part of how we deliver - it means we bring together the right consultants, engineers, certifiers, suppliers and specialist trades for your project. With strong relationships already in place, we ensure every detail is carefully considered so your build runs as seamlessly as possible.

Behind the scenes, our contract administrator, Dan - ensures all documentation, design coordination and project details are carefully managed from the outset. With a background in Architecture and construction project management, he helps keep each stage structured, compliant and aligned so nothing is missed throughout the build.

If you’ve got the project lined up but need finance sorted, we can help there too. We know a trusted finance professional who works across residential, investment and business lending, not just construction. If it makes sense for your situation, we’ll make the introduction early, so you’ve got clarity on numbers before we start.

We’re always happy to answer questions along the way - no question is ever a silly question because we believe informed clients feel more confident and supported throughout the build process.

Our Projects

At Lummy & Co, clients come to us with plans that mean something. Plans for how they want to live.

New Builds, Renovations & Extensions

Sometimes it’s a new build on land they’ve waited years to own. Sometimes it’s a major renovation of a house that’s never quite worked — the kitchen cut off from the family, a living room that never gets the light, nowhere to be together and nowhere to be alone.

Often, it’s an extension that finally makes space: for kids, for parents, for work, for rest. We bring those plans to life. We build the kitchens that become the heart of the home. The bathrooms and ensuites that give you a moment to yourself. The laundries that just work. The open-plan living areas that connect to the outdoors the way they should.

We transform houses into homes. We take your plans for places that are tired, tight, or disconnected, and build them into spaces that feel like the people who live in them.

You bring the vision and Lummy & Co builds it into reality.

building with a difference

Since the beginning, Lummy & Co has been about more than just building and renovating homes. We’ve always believed in building with a difference — finding ways, big and small, to give back to the communities around us, near and far.

Through our Homes to Hearts initiative, this has taken shape in simple, meaningful ways over the years. From supporting organisations like O.U.R Rescue, getting behind Free Trade Days, and contributing where we can to local not-for-profits such as We Care Connect, it’s never been about scale — it’s about showing up when we’re able, in ways that feel genuine to us.

Sometimes that’s financial support, sometimes it’s time and skills, contributions to appeals, or simply helping spread awareness. Small actions, but ones that we hope make a meaningful difference where it’s needed most.

At the heart of it all, we believe building homes should always go hand in hand with building community.

“We had our agents here today to value the unit for us.
They said they’d never seen such an incredible renovation before and that they had seen a LOT of them.
They were blown away by the quality of everything, touching the doorframes and the gold hinges and door handles and the gold parts on the door frames. I told them how you put all new door frames and door and hinges, and they loved it! Loved that it was done so thoroughly. they loved the lighting and how it made the ceiling look higher even though you lowered it, the flow of the laundry and kitchen and how bright light and spacious it felt.”

— Vanessa from Terrigal
