Years Established

Completed Projects

“KJK converted our garage to a versatile workspace / family room / self contained ensuite in record time during the pandemic. Always adhering to health and safety / Covid measures, and as silently as possible given that we were WFH, I can’t fault the skills of the trades or the guidance on what to do and how to make savings along the way.”
