We had peace of mind that with John's expertise, our project ran smoothly while we were overseas." Leigh G
Mascot 1st floor addition - Before

What makes building through us better?
Clients come First
Unlike other builders, we are independent and we work for you. The success of your project is our top priority. We believe that with professional, honest and fair conduct, home building becomes a positive and rewarding journey for both clients and building professionals alike. As independent client side licensed builders and project managers, we manage the design and build from the clients point of view.
Early design advice
Before talking to an architect. Talk to us. We ensure your home design suits your budget and lifestyle before you commit. If you don't have plans, we will appoint the right architect or designer depending on your specific council and situation. Our value is in that we check the design work along the way for cost saving opportunities, buildability and potential risks. As experienced project managers on active projects in the construction cycle, we find that we have a better feel of actual build costs than designers. We make sure you don't overdesign a home that you can't afford to build.
Don't risk going building contract blind
You might be thinking about engaging a builder from the start. But how do you know you are getting the best builder, the best deal and that they haven't deliberately left a bunch of necessary items out of the contract? Your expert building advisor prepares a detailed scope of works with everything you want and ensures your quotes come in on an apples for apples basis. This way, you can rest assure that you have done as much as you possibly can to avoid nasty variations or other surprises when you are on site.
Quality Control
Nothing makes us happier than seeing our happy clients move into a home they love. We take pride in our projects and have quality control systems in place to ensure your home is delivered with the highest level of precision and craftsmanship. It is our attention to detail that sets us apart.
