About Us

SR PassiveRetroFit Homes and Extensions has grown out of the increasing demand for better-built homes and extensions across Ireland. We aim to be Irelands’ leading builders in regard to providing energy-efficient homes. Passive Homes are becoming increasingly popular as a way of saving energy costs and helping to reduce our environmental impact. The business is based in Portlaoise, Laois, yet we work on a variety of projects across Ireland.

Our team has the experience required to complete every aspect required for both new-builds and retrofitting existing buildings. From the floor to the roof, we apply industry-leading standards to get your home insulated.


A passive home is a highly effective building standard that promotes significant indoor comfort. Our team installs a variety of passive home features which promote significantly better living conditions for the entire household, especially suitable for those most affected by difficulties such as asthma.

The Irish-owned business is led by the experienced builder Shane Reilly. His reputation as a builder has been built with over 15 years of experience. As a certified carpenter/joiner, Shane has worked throughout Ireland and England on all aspects of building homes and renovations. Expertise in timber frame building and fabricating has brought many successful projects. In recent years, his focus has been on developing high-quality Passive Homes and energy-efficient Renovations and Extensions.
