1970s house transformed into a Passive House

An existing two storey 1970's house with a flat roof was completely transformed by the addition of an additional storey on top to create a 275 sq.m (2,950 sq.ft), five bedroom family home. The whole house was refurbished to EnerPHit standard (the Passive House Institute standard for existing buildings), which is the highest standard of energy efficient construction. The shape of the roof creates a flat roof along the ridge, facing south, to ensure maximum efficiency of the roof mounted solar photovoltaic panels.

The project was awarded the RIAI Architecture Award for Sustainability in 2022 and the NetZero Ireland Construction Award for Retrofit 2022.
