An ethical approach to development
has remained fundamental to Connolly & Callaghan’s work as a family construction business
for more than three decades.

Connolly & Callaghan was set up in 1985 by Martin Connolly and his father-in-law Eddie Callaghan. Martin had worked in the building trade since leaving college, and Eddie hab worked as a carpenter.

A strong social ethos led to C&C acquiring properties for use in the rented housing sector. Poor quality single houses were converted into flats, or refurbished into hostels, and today, C&C is a primary provider of temporary Emergency Accommodation (EA) for families in Bristol and South Gloucestershire.

In the 1990s, 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. Many 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 is currently developing homes that use straw bales for insulation, as an affordable, practical solution to both the UK’s housing crisis and the challenges of fuel poverty.

At the heart of our approach is a belief that construction can be a force for good – whether in providing shelter for vulnerable individuals, or in creating sustainable homes for the future of the planet.


A sustainable society,
in which individuals can develop and grow,
based on respect for each other, nature and the planet we depend on.
