WE ARE NOT just a standard Granny Flat builder that wants to sell and build you a square box. We offer a complete Conceptto-Completion high end service. We offer a total and complete ‘done for you’ Fixed Price Granny Flat Package.


INTEGRITY + TRANSPARENCY are the core qualities and beliefs of our Company. Integrity means adhering to moral and ethical principles and not wavering from this belief. Transparency is being open in communication and accountable to our clients. It means being big enough to accept both criticism and praise and responding to both. We do not believe in gradual commitment.

Building sites ARE complicated. Anyone who says they are not are just selling to you!! All building sites present hurdles. We are a highly efficient and organised building Company. We are great at getting over hurdles!


We ARE the builder. We don’t pay Commissions to builders. Your job won’t be farmed out to an independent builder. We hold the builder’s licence and are accountable and transparent from concept to completion.


DON’T BE FOOLED by anyone offering you a price online. These companies over charge to cover all building and site issues. Online calculators… cannot deliver a FIXED PRICE!!

Building is complicated and emotional. Delivering a FIXED PRICE is done by a thorough and transparent process. We do not believe in gradual commitment by offering an attractive cheap price and then add on throughout the approval or building process.


We offer a clear, transparent Preliminary Approval Package that will deliver a fully Fixed Price. We do this BEFORE you are committed to a Contract. This includes ALL site costs which are factored into your price and completely removes the fear and uncertainty of Costly Budget Blowouts.


We sell much more than just a price. If you are buying based purely on price, the Granny Flat you end up with may be dictated to you by a dodgy builder or a Granny Flat builder that takes short cuts, never delivers on time or hits you with expensive variations and extra costs not clearly covered in the Contract or defined in the scope of building works.

If you want a cheap Granny Flat builder please ask. I can recommend some to you.


WE GUARANTEE that when completed your Fixed Price Granny Flat will provide you with an excellent, positively geared Return On Investment (R.O.I.) which you can reasonably expect to be 16% – 22% (* area specific), sometimes even more. As you know, you can only get that return from gambling on the Stock + Share Market


WE GUARANTEE that a Fixed Price Granny Flat will add value to your existing property. We will also provide options for complimenting your existing residence so this added value is optimised to the highest possible level.


WE GUARANTEE that our team of tradespeople are handpicked building professionals that will deliver a Granny Flat to you ON TIME, ON BUDGET and completely DEFECTS FREE.


We can provide details of past and present satisfied clients. We also offer a free subscription to our monthly newsletter that provides current updates, changes to our industry, regular pics, videos and testimonials from our current Granny Flat building projects and clients


We have never had a breach or claim against our Builder’s Licence No. 224964C. We have never been in any Consumer, or Office of Fair Trading tribunal for any breach, or building claim. We have never had any Home Warranty Insurance Claim lodged for any building issue……… EVER!


WE HAVE BUILT Granny Flats in most Sydney suburbs from Camden to Palm Beach, Miranda to Wentworth Falls, Pendle Hill, Sylvania, Doonside, Castle Hill, Glenfield, and many Northern Beaches suburbs that our satisfied clients will allow you to inspect.


What our customers are saying…

‘I couldn’t get a Fixed Price from any builder. I already had a good builder lined up but he was unable to give me a Fixed Price. This was important to me due to my budget. Greg Messer was the only builder that was able to give me a Fixed Price. The night before I met Greg I was watching some of his Granny Flat videos and I saw one that he had just finished at Pendle Hill. I rang Greg the next morning at 6am. He answered the phone and came over that day. Greg did the entire approval package for me and at the end of that process I was given a Fixed Price. The bathroom and kitchen are a great size. I told Greg Messer that I wanted a cast iron bath and provisions were made for this and I am very happy with the outcome. I would recommend them to anyone.

Thank you’

‘Hi. I am John from Oxford Falls and I am just giving a testimonial for Fixed Price Granny Flats and Greg Messer. The experience we had was a great experience. We wanted an attached Granny Flat that matched our house and did not look like an addition, but looked like it was always there. Greg and the boys did an incredible job in making sure that it all matched up and connected well. Our neighbours walk past here every day and say how awesome the place looks.

On top of that we had a great experience with Greg and Fixed Price Granny Flats. Their service was amazing and we are very happy customers’

‘The overall experience was excellent from the start, the design, the proposal through to the construction phase. Some of the key aspects to this project were the challenging site, a very steep site. One of the key considerations I was looking at was the ability of the Contractor to deliver the project on this site ...... the Fixed Price was delivered. Greg and his team delivered on this price.

I am involved in project management and work in the engineering eld and work in this type of space. Fixed Price Granny Flats were not the cheapest quote I had but in terms of features and fixtures were of excellent quality when comparing quotes. This was a key point of difference. Also the trades were excellent, especially the builder who had to coordinate the entire building from 40 metres to the street level. I thought this would be an issue..... but it was no issue at all.

The sewer and Stormwater issues were considerable on this site. It was challenging and this cost was factored into my quote. Greg was very transparent with the entire process. I am a fairly fastidious client and Greg was exceptionally responsive to my needs we worked collaboratively to resolve issues and challenges and find solutions that arose during this project. This was an important aspect and I appreciate this. It was important to me.

Overall my experience with this project was that it came through on time, within budget and defects free. This was a really good outcome. I will be referring friends and family to Greg and the team at Fixed Price Granny Flats’

‘My name is Leonard Smith. Some time back I engaged Greg Messer from Fixed Price Granny Flats to build us a 60 square metre Granny Flat. The Granny Flat now is complete and we are very, very happy with the end result. The roofing is excellent, the timber treated frame complete with brick veneer finish. We have no complaints about the workmanship whatsoever. Very happy with the end result and have no hesitation in recommending Fixed Price Granny Flats for any of your future projects in relation to Granny Flats or any other building work.

The office girl is beyond criticism, forever helpful. What more can I say. The project Manager is Kieran. Greg Messer is the big king pin there, he’s the boss.... very easy to do business with. Very obliging within reasonable parameters, naturally. That’s it and my wife would like to say a few words.

My name is Swannee Smith and we are very happy with our Granny Flat. Anything I wanted to change within reason, they were very obliging..... We are very happy with the crew, no complaints.

Thank you’
