OVERVIEW

North-east of Dublin in the coastal suburb of Portmarnock is Drumnigh Oaks, Ballymore’s first Passive House development. 15 of the 25 four-bedroom homes are built to the internationally recognised standard, using innovative design,  eco-conscious materials, an intelligent use of space, and energy-saving technology.

Airtight construction, Mechanical Ventilation with Heat Recovery (MVHR), advanced triple-glazed window systems and super-insulated walls ensure low energy bills, reduced air pollution and condensation. These are houses that use less, work better and give back more.

Drumnigh Oaks embodies sustainability principles through every stage of the project. The homes incorporate low-energy construction methods, use Tabihaus panels (made from recycled materials) in place of traditional wet boards, with paints sourced through Enable Ireland’s circular economy scheme the Rediscovery Centre.

Floor-to-ceiling heights are optimised for resource efficiency, with all this contributing to a reduction in energy use of 56% compared to conventional housing. Heat loss is reduced by 50% and air pollutants by 90%, while an upgraded, more efficient pipework system prevents water loss, stagnation and wastage.

Beyond the trailblazing construction, these are the real homes that families need. Not just a place to stay, but a place to live. A connected, safe, community-focused life, close to the city but with quieter surroundings. Drumnigh Oaks is a testament to what can be achieved when sustainability is not just a feature, but a foundational planning principle, and where every element of the design and build is approached through the lens of innovation and environmental responsibility. These are places built to last, to meet the standards of the future, with the quality of construction delivered by Ballymore mirroring the quality of life that’s made possible.

Drumnigh Oaks is a collection of 30 family homes designed for sustainable living – and Ballymore’s first Passive House development.

“There’s a reassurance that comes from knowing your home is not only good for you day to day, but also better for the environment. It genuinely enhances how the space feels to live in.”

Vincent O’Gorman, Resident at Drumnigh Oaks

“We have invested heavily in both design and construction to create homes that are not only more energy-efficient and healthier to live in but also truly beautiful spaces. This development is about more than sustainability, it’s about building homes that people love to live in.”

Linda Mulryan - Deputy Managing Director, Ballymore

“At Drumnigh Oaks, we’ve pushed the design boundaries, overcoming complex challenges to meet Passive House targets. For homeowners, this translates into lower energy costs, exceptional indoor air quality, and the reassurance of living more sustainably.” 

Charlie Conlan - Sustainability Designer, BALLYMORE

“I’ve fallen in love with the community here.”
