Dedication Meets Opportunity - The Evolution Of A Flourishing Business

Back in the 1990's brothers Ralph and Ian Pathuis were working for a builder, when they took advantage of an opportunity to take over the business when the owner moved on. Then in 2001 the brothers decided to part ways, and Keystone Home Additions made a start in Ralph's capable hands. Since then, through hard work and innovation Keystone has set themselves apart as experts in second storey additions (aka first floor additions).

Significantly, they've developed methods of work to enable their customers to stay safely in their homes during the project, saving many happy home owners thousands of dollars in moving fees, rent and storage.

Ralph brought his son Steve into the business as a director in 2008. Together they have built a family team of dedicated home extension builders, all fully qualified and licensed in their chosen trade, and kept fully up to date with professional development, in order to offer you the highest quality workmanship and customer service for the duration of your home extension.
