First Floor Additions

When re-establishing the structure of your existing home to accommodate new lifestyle needs, it is vital to use only professionally trained experts in their field who are fully adept in the renovation market. Blending old and new is not something to be taken lightly.

Design & Construct

Don’t spend 20k-30k designing your amazing new space only to discover you don’t have the finance to match construction costs. Having to start again is devastating to the point where many families often give up. Get what you want within the reality of the budget you have

I could not recommend Scott, Nigel, Pat and Adrian more highly. They renovated our tired old 1993 kit house in Glenn Alpine and turned it into a new spacious and luxurious home. True craft mens, polite, easy to get along with and great value for money. They added a massive amount of value to our property!

Ben, Dave & the team worked worked with us to renovate our home in 2021. They added a first floor addition, gutted & re-did the existing bathroom and laundry downstairs, added a new outdoor entertaining deck & improved the whole facade of our home. The work was completed on budget, as quoted and in just 8 months.Dave, was an excellent project manager; easy to work with, answered all our questions, kept us in the loop the whole way and provided great recommendations. All of the builders and trades were extremely polite and lovely to deal with, in fact our neighbours were also very complimentary throughout the whole process. The attention to detail, professionalism and quality from the team was exceptional. We are thrilled with the end result for our 'forever home'!

Absolutely outstanding builders. On time, quality work, even came in under budget. We got a second floor added to the house. The builders were courteous, professional, and did an excellent job. The extension was built and completely enclosed in the first 3 weeks, while we still lived inside without disruption. The rest of the fit out was completed over the following 8 weeks. Less than 3 months all up from start to end. They never missed a deadline, always arrived when they said they would, and never made a mess. Perhaps most amazingly, they came in UNDER budget. Honestly, I didn't know builders could be this good. If you are considering adding a second floor to your home, don't use anyone else.
