A Retrofit Template for Bungalow Bliss Homes

Sustainable architecture begins with restraint. Reuse is one of the most practical climate actions the built environment can take. Keeping buildings in service, cutting waste and improving performance is how we reduce carbon without stripping places of memory. 

Woodlands sits within a wider Irish housing story. The existing home is a Bungalow Bliss property in Belleek, Ballina, Co. Mayo, on the edge of town and within walking distance of daily services. Bungalow Bliss homes are part of a typology shaped by late 1970s plan books and widespread rural self-build. The model supported local construction economies, sustained small contractors and trades and aligned with Ireland’s long-standing policy emphasis on private ownership rather than large-scale public housing provision. For many households, it was the most viable route to secure a permanent home. Fast forward to today, and many of these houses no longer fit modern living patterns and their building materials are often inefficient, leaving households with high running costs and fossil fuel dependent heating. 

ACT’s response asserts strategic renovation and a fabric-first retrofit. It modernises the family home by reworking the plan within the existing footprint, then upgrading fabric and performance. This becomes a repeatable template for similar homes, scaling impact architecture through modest intervention. 

Replanning a Bungalow Bliss home for modern living

The brief began with the idea of an extension. Instead, ACT tested three options against layout, lighting and budget and kept returning to the same question: how can the house do more with less?  

The plan ACT chose serves a family across generations with three bedrooms, a combined kitchen and living space, a study and a bathroom and utility. Internal walls are removed and the long central corridor is absorbed into the main living area, increasing liveable space without increasing floor area. 

Making the living space the heart of the home

The plan centres on a living kitchen space that opens to the rear garden, drawing daily life toward light and landscape and strengthening the link between inside and outside. 

ACT’s design reinforces the living kitchen space’s role as the heart of the home through section and daylight. A vaulted ceiling lifts the room, while two large sliding doors frame the garden and capture evening light. A long strip of skylights bring morning light deeper into the plan, keeping the space naturally lit throughout the day. 

To support this shift, ACT removed a rear shed and freed up additional daylight into the house. 

Retrofitting the fabric to cut operational energy title

ACT has worked to rebuild Woodlands’ performance from the fabric out, focusing on the elements that shape comfort and day to day energy use. The team has added new insulation to the floor, walls and roof, upgraded window performance and integrated airtightness so the house holds warmth more effectively and reduces heat loss.

As part of the energy retrofit, ACT has undertaken a BER assessment, a building energy rating certificate that rates the performance of a home, and set a target of A1 energy performance, while also planning a life cycle assessment.  

Reusing and selecting materials with care

ACT treated the existing house as the primary material resource, keeping the structure and working from what was already there. Roof tiles, doors and skirting boards stay in use where feasible, and have been retained both for their material value and to reduce embodied carbon through straightforward reuse. 

New materials entered the scheme with a tight brief. Birch ply brings warmth and continuity across the interior, offering a durable finish without expanding the palette or adding unnecessary layers. 

Budget set the limits. ACT prioritised fabric upgrades and overall performance. ACT’s approach stayed consistent throughout: reduce material use, keep what works and make every new element work harder. 

Working with a family brief across generations

The resident family shaped the work from the start, with a clear focus on how they live now and how the home needed to support the next generation. To this end, ACT approached the project with a people-first mindset, updating a 1970s house without losing its everyday ease. 

For example, the existing building carries memory. By retaining fabric and working with what is already there, ACT’s design maintains continuity of place while allowing the plan to change and the house to move forward. 

Shaping a repeatable model for rural retrofit

ACT set Woodlands up as ‘a template for a template’, demonstrating how a Bungalow Bliss home can meet modern needs through targeted changes to plan and fabric rather than major intervention. The Sustainable Energy Authority of Ireland (SEAI) estimates that around 300,000 similar bungalows are scattered across rural Ireland, with roughly 80 percent carrying low BER ratings. By improving an existing home rather than replacing it, ACT’s deep retrofit sets out an approach others can apply across this extensive building stock. 

To this end, ACT’s work intentionally remains grounded in the reality of the Bungalow Bliss typology. Many of these homes now lie between everyday living patterns that have shifted and fabric performance that no longer holds up. Woodlands shows how change can happen without erasing the character and memory that make a house feel rooted in place. 

By replanning within the existing footprint, targeting A1 energy performance and prioritising reuse alongside deep retrofit, Woodlands is a practical model of adaptive reuse in domestic sustainable architecture. As the project moves toward its expected end in 2026, its long-term value will rest on what it proves can be repeated. 

‘Bungalow Bliss houses aren’t a problem to be solved, they’re a resource to be unlocked. With the right retrofit and spatial rethink, they can become some of the most adaptable, low-carbon homes we have, generous in plan, modest in scale and rooted in place.’ 

‘Listening to how our client lives in their home helped us reimagine the Bungalow Bliss typology from the inside out. What began as a bespoke conversation evolved into a practical template for future-proofing similar houses nationwide.’ - Kevin Loftus, Architect.
