At Sustainabuild, we believe that the best buildings honour the past while embracing the future. Our mission is to help homeowners, architects, and developers transform properties into spaces that are healthy, efficient, and sustainable — without losing the character that makes them unique.

We specialise in two areas that are rarely combined but deeply complementary:

• Heritage retrofits and conservation — breathing life back into period homes with solutions like lime plaster, breathable insulation, timber cladding, and damp remediation.

• Modern sustainable construction — advising on mass timber, airtightness, thermal bridge diagnosis, passive house principles, and natural building materials.

By bridging these two worlds, we create projects that are both technically high-performing and deeply respectful of Ireland’s built heritage.

Our Approach

Every building tells a story. We start by listening — to the property, to its history, and to the needs of its occupants. Our consulting process balances:

• Science – proven sustainable methods, airtightness, energy efficiency.

• Craft – traditional techniques suited to Irish stone, timber, and climate.

• Care – independent, practical advice that prioritises long-term building health.
