Martin Connolly partnered with his father-in-law, Eddie Callaghan to establish Connolly & Callaghan in the 1990s, originally established as a building company; Martin worked in the building trade after music college, and Eddie was a talented carpenter. 

C&C acquired properties for use in the rented housing sector. Poor quality single houses were converted into flats, or refurbished to a higher standard and used to house those in need. 

As part of our commitment to the environment, C&C made the decision to move from refurbishment to new build construction, and to date have successfully completed a number of significant eco-build projects incorporating hundreds of self-contained dwellings. Nearly all of these properties were developed on brownfield sites.

C&C has made considerable investment through into research and development of construction methods for highly-insulated homes using renewable materials.

In 2009, C&C won the Environmental/Conservation Development of the Year for timber framed blocks of flats at Pennywell Green, which were the first Grade 4 eco-development in Bristol. In 2016 it constructed the UK’s first publicly-available timber-framed homes insulated by straw bales in Shirehampton, Bristol.

C&C continues to develop homes using straw bale insulation, as an affordable, practical solution to both the UK’s housing crisis and the challenges of fuel poverty.

This movement towards sustainable, practical building solutions evidences C&C's belief that construction can be a force for good; providing shelter for the Vulnerable and creating sustainable homes.
