Rochestown House

This redevelopment and extension of an existing 1970’s sheltered housing scheme presented many challenges on a tight urban site, which we completed in three phases commencing with an Energy Retrofit to existing apartments in Block 2, a Passivhaus Europhit refurbishment of Block 1, and finally 14 new-build units to full Passivhaus Standard. The M&E value was in excess of €2m.


Designing the upgrade and extension of an existing 1970’s 2-storey apartment block into a Passivhaus-certified 3-storey block. Significant fabric, airtightness, Part M and Part L upgrades.


Passivhaus Certification achieved, Winner – 2017 Sustainability Project of the Year RIAI Architecture Awards.
