We have been working in the industry for 10 years and in this time, we have established ourselves as a name that our clients can trust. People know us for the integrity, quality, and professionalism that we have shown in our work over the years. Our clients can trust us that when they hire us for such development and construction projects, we would deliver the work within their time and budget. 

We work all around the city. We are adept at various facets of such work, including:

  • Property development

  • Management

Why should our clients choose us for such work?

There are several reasons why people should choose us for such projects. First, we always handle one project at a time. This is the reason why our clients can be sure that they would have all our attention. As opposed to so many of our peers in the region we take all the time to make each project, which we work on, unique. We take into consideration what our clients want us to do and act on that.

Our clients can trust us

We are a family-owned and operated business, we understand the value a granny flat can bring to the family. So our clients can be sure that they can trust us as granny flat builders inWestern Sydney

We offer them the most tailored experience that they need for the work. We have experts for every aspect of the project to make sure that our clients only get the very best from us. This is also the reason why we are the one-stop-shop that our clients want for such projects.

How do we work?

We follow a defined process for work in this area. First, we talk with the clients to determine if their site is eligible for us to build a granny flat there.

After that, we perform a site inspection that comes free of any obligation. We then offer a preliminary tender. After this, we sign a contract and design the granny flat. In the fourth stage, we take these designs to the local council so they can approve of it. After that, we select the materials with which we would build the flat. Finally, we start the construction and finish the project as per the specifications of our clients.

We’ll update you at every stage of development, and make sure you are satisfied and informed of all the new features before we hand over the keys. 

Why are we the best?

We are the best granny flat builders in Western Sydney and much of this is because of the tailored experience that we can offer to our clients. We are confident that the work we do is far better than what our compatriots in the industry can – they cannot touch us. All our team members have worked in the industry for over 10 years. They are among the best professionals that our clients would get in this neck of the woods. We can also provide our clients with complete guidance regarding the project that they want us to complete for them.


Something that will exceed your expectations, and something that you would be proud to call Home!! It’s Our guarantee!!

Its’ a big claim, this confidence is the result of many projects built and lessons learned in our building experience. Experience shows us there are several things clients find alarming about any construction project…and we make sure they never happen.


NO unpleasant Surprises. All our work is outlined in detail, and therefore everyone has the same objectives.


Budget blow outs. Your price is fixed, as listed in the contract.


Fear of poor workmanship. We stand by our work, AND all work is covered by our 6 years (structural – if you need to add clarity) warranty.


Damage to your property. In the unlikely event such a thing should happen, we are fully insured for Public Liability.


Your home is left a mess. We always clean up at the finish and do a final inspection with you to ensure your complete satisfaction.

Imagine how you will feel when your home or project is finished on time, looks just like you want and all within budget. Everything is clean so you can relax and enjoy the new look.


As a local family owned business, we believe that it’s the little things that matter and we take pride in our services.
