Managing Director and Registered Builder: Jai Evans

Jai has been involved in the Australian construction industry his entire adult life. A skilled carpenter by trade he has worked for many large companies in both the commercial and residential building sectors. These ranged from commercial fit out projects to building new architecturally designed high end homes for builders. Once confident he had obtained enough hands on experience and supervisory knowledge he founded his own successful business for carpentry and smaller building work. Undertaking roof additions, new roof construction, second story extensions, decks, roofing, alfresco's and renovations work. 


Jai quickly progressed to becoming a WA registered builder. He then founded "Perth Home Extensions". Given his prior experience in extensions and renovations, he decided his business would be aimed at Perth's ever expanding home renovations and extensions clientele. 

"I created Perth Home Extensions because I am passionate about Home Renovations and Residential Building. With our speciality in Home Extensions and renovations we fill a very important niche in Perth's ever expanding development on existing property's. I manage every aspect of the construction project from concept to completion and I personally ensure the upmost attention to detail and quality are delivered on every Build"
