Our story

From one builder to a family of three

Robin Griffiths started building over 40 years ago. When his sons JP and Matt left school, they joined him on site and learned the trade from the ground up — literally. Both became qualified builders under Griff's guidance. Today the three of them are the Griffiths family business, with JP also a Licensed Building Practitioner.

There has never been a marketing budget. Every job has come from word-of-mouth — a neighbour who saw the finished deck, a family who trusted the team with a garage extension. That is still how the work finds them.

Why Canterbury keeps recommending us

"JP and co did an amazing job with our garage extension. They are a one stop shop type builder from that old school for all types of building works. Easy to deal with and no hassles. Would recommend them highly."
