Bespoke garden rooms for every lifestyle
CDM Ireland Limited designs and builds garden rooms in Craigavon that are custom-made to fit your home, your needs, and your style. Our fully insulated, permanent structures are perfect for turning unused outdoor spaces into practical living areas, whether you want a home office, gym, studio, or relaxing retreat. Using our advanced, breathable wall systems and high-performance insulation, we make sure your new space is comfortable all year round, not just during the summer months. We never use standard templates, so every installation is unique and tailored to your requirements. With us, you get a garden room that truly feels like part of your home.
Why choose our advanced outdoor rooms?
Our garden rooms are built with LEED-certified methods, ensuring your project supports sustainability and uses ethically sourced materials. We incorporate Passivhaus principles, such as high-performance glazing and airtight construction, helping you save on energy bills while enjoying stable indoor temperatures. Each structure is engineered as a permanent addition, moving well beyond the limitations of basic timber outbuildings. In Craigavon, our builds are designed for lasting value, giving you confidence in your investment and a space you can rely on for years to come.

The benefits of a custom garden room
Adding a bespoke garden room gives you extra living space without the disruption of a house extension. You can enjoy a quiet place to work, exercise, or relax, all within reach of your home.
