“Steve’s Story”

Steve came to us after receiving a couple of quotes from local granny flat building companies. After some quick maths on the back of a napkin; he made some assumptions for the cost of timber and bricks and came to the conclusion, that something wasn’t right here…

After some more research online for the cost of windows, doors and roofing. He definitely knew something wasn’t right – Why were they quoting him so much?

We did his plans, engineering specifications and showed him the steps to take. (Just to explain Steve works as a project manager for IBM. This is a full time job with long hours. Steve has 2 kids and not much spare time at all.

Even in his circumstance he managed the build of his granny flat using this program and saved $40,000 from those initial quotes received.

“I was completely gobsmacked with how much a local builder wanted to charge us to build a granny flat, and am so thankful I found you guys online!”

I work full time and don’t have time to add a building project to my life. However, with the ease at which you showed me to plan out trades and materials, with a few hours a week, scattered before, during and after my working day, I saved $32,000 on our 2 bedroom granny flat.

Mark and Dean were both there for me when I had a question and guided me on what to do. I feel truly grateful that I went down the owner-builder route and saved my family this money, the $32,000 saved is actually more like $60,000 saved after tax with my salary. Thank you guys and please know I will be spreading the word far and wide!

“It took me a couple of weeks longer than 4 months, but I saved an extra $4,000 on top of the builders margin!

We smashed through the first 3 quarters of the build in no time. Just taking our time at the end to pick and choose which tasks we could do our selves (like painting). We saved easily more than $25,000 on our build and had no experience in construction before.

I take my hat off to both Mark and Dean for taking the time and the dedication to explain everything that we needed to know. And doing this without bombarding Carolyn and I with useless knowledge that many text books prescribe.

Thank you, guys! Both from me and Carolyn from the bottom of our hearts.

“I recall getting BILL SHOCK when I saw the quotes come in from granny flat building companies –I thought there must be another way”

When I started looking online to build a granny flat for my elderly mother, I expected to pay a fraction of the quotes I got from building companies in my area.

My heart sank, I kept thinking why are they charging so much for a simple granny flat? The design I wanted was small enough to just swing a cat inside. But quote after quote, they seemed to come in higher than the last.

I gave up for a few months (dishearten) then started looking online and came across DIY Granny Flat. And I am glad I did! I could trust them, because I wasn’t buying materials from them. I wasn’t hiring them to build – Just leaning on their incredible knowledge to craft something beautiful for Mum.

She is absolutely delighted and I was thrilled to build it for 30% off the highest quote I received. You have a lifetime friend and fan. Keep doing what you are doing guys!

You hire a building company to take over and accept that you will be charged (On average 25%) over the cost of the tradies and materials.

What that means in dollar value is; if you are quoted $120,000 for a 2-bedroom granny flat, you have to accept $30,000 (on average) will be going into the back pocket of a builder.

That is the same as you paying $577 every week for a year to someone you don’t know, to do something that you can do (No matter your experience)

This option is simply out-of-the-question for most of us.

Plus, builders will tie you into contracts that can work in their favour
“Do you want to add a window in the second bedroom? That will be a $X,000+ variation fee thank you very much.”

Builders sub-contract work out to tradespeople anyway, especially when they are busy. Do they check their work? It is hard to do, especially when they have a few building jobs on the go.

Are they taking their time? Or are they focused on completing the job as soon as possible to receive final payment.


You hire a “Project Manager” to do what we show you. But be prepared to pay around 10% of the construction cost for doing so (…Well, at least 10%)

That means for a $120,000 build you pay then at least $12,000 for the privilege of talking to tradespeople on your behalf.

However; you still need to make all the decisions. Truth be told; nobody cares more about your granny flat than you. So, take out the all-important “factor” of love and appreciation for the work being done, and your are still short changing yourself for thousands of dollars.

They don’t understand the importance of the design specifics you want.

They don’t understand than “near enough” is NOT “Good enough”

They have other jobs on as well, no just yours – So the attention to detail is spread across multiple construction sites and it simply opens up situations where things get missed.

Don’t get us wrong.

Heck, we have dear friends who are builders so we know exactly how the industry works. We just understand that for a large percentage of Aussies out there, this is NOT IDEAL in anyway.

We have never seen a project fail when the control is put in your hands (Only when the control is given to someone else… With an open check-book attached to that control…)

And scary stuff can happen… Trust us on that one.

This is in no way meant to “bash” building companies, it is just to provide an alternative to save you money and ensure you get EXACTLY what you ask for.
