& Interstate Homeowners: Your Trust, Our Priority
Steve
Forster, New South Wales

loop. I would build with them again and recommend them."
Simon Wright
Coogee, Sydney
"I had a really great experience with Wilson Design and Build. Being out

nervous but from concept to handover the whole process was incredibly
smooth. Great team, Great communication and I am very happy with the
final product. definitely recommend."
Elisabeth Gallagher
Whishart, Brisbane
"We have had a great experience with Wilson Design and Build. We had
never built before and were quite nervous about the whole process, but
they were able to develop a concept and design to achieve something
that we didn't think was possible. Great communication right throughout,
and the outcome has exceeded our expectations. Highly recommended."
Kira Holt
Buttaba, New South Wales

granny flat build seemed like a breeze. Thank you again for making the
process so smooth and keeping us updated throughout the entire build.
We can definitely recommend working with these guys!"

from beginning to end. Being from interstate, they answered all my

use them again in the future!"
Zheng Wang
Brisbane, Queensland
"I find it is very easy to deal with Mark Wilson. I have very high
expectations to the granny flat and they work hard to achieve that. For
anything I don't understand, they are always willing to help. Nothing is
perfect, but I do feel they are honest, professional and able to deliver
what they have promised. I would recommend them to anyone who
wants to start a construction project."
Matthew Roberts
Oakdale, New South Wales
"I have recently completed a build with this team to build a granny flat on
my investment property. From the quoting stage to handover, everyone
has done a fantastic job. The process was smooth, the communication
was great and I'd be more than happy to build with them again. Quality
job and completed quicker than the anticipated completion date."

Unlock Equity
Are you sitting on untapped equity in your current property? Our service empowers you to turn that idle potential into a thriving income stream by building a duplex, granny flat, or new investment home.

We specialise in leveraging the equity you’ve already built, guiding you through the entire process from planning to construction. Our tailored solutions ensure your investment perfectly aligns with your financial goals, whether that's massively manufacturing equity, creating consistent positive cash flow, boosting rental yields, or facilitating strategic refinancing (equity drawdowns) for future investments.
Secure your financial future
With our expertise, you can confidently embark on a journey to increase your wealth and secure your financial future. Don’t let your equity sit stagnant—turn it into a smart, strategic investment that works for you, bringing consistent, predictable returns.

A Superior Building Process
We believe communication is key. This is just one of the reasons our clients come back to us.
01
Your Foundation for SuccessAlthough most Brisbane council regions classify Granny Flats as 'Accepted Development', there are specific requirements, design elements, and precluding factors that may hinder or impact your project.
Whether you are considering building a granny flat on an existing property or conducting due diligence on an upcoming purchase, we begin every new client relationship with a thorough, complimentary remote viability check.
We evaluate your property to give total certainty and peace of mind from the outset whether a granny flat is possible, what you will need to consider regarding floor plan size, parking, frontage, and lot size, and how we can make it a reality.
02
Once viability is established, we will work collaboratively with you to define your vision for the granny flat or dual occupancy. This is the perfect opportunity to combine your strategic goals with our wealth of building experience to design your ideal project.
We advocate for a site-centric design approach, analyzing the site first to tailor the dwelling to its features, which can save money and time by avoiding extra expenses for leveling or retaining walls. You can utilise one of our standard designs, meticulously refined for specific areas of Brisbane, or start from scratch and design your Granny Flat from the ground up.
After developing your concept plans, we move to a preliminary agreement to perform a scope of work requisite to delivering you a fixed-price building contract. We identify any potential problems before they arise, leaving you with total peace of mind surrounding the cost of your granny flat or duplex.
03
Upon completion of preliminary work, we will present you with a fixed-price HIA building contract, ready to be signed. Regulated by the Housing Industry Association, your HIA contract provides meticulous support, allocates risk fairly, and outlines all legislative requirements.
Along with your HIA contract, you will receive your:
- Construction Plans and Drawings
- Specifications and Inclusions Details
- Fixed Site Costs and Costing Breakdown
- Soil Test
- Foundation Engineering
And most importantly! Your Construction Start Date (pending finance).
04
Once you have signed your HIA contract and confirmed your proof of finance to support the build, we are all set to get started. Upon commencement, you will be introduced to your personal Project Manager and Site Supervisor, provided with a construction brief, and confirmation of your build timeline.
We believe transparency creates accountability, which is why your client portal connects directly to our own project timelines. This provides one source of truth for both builder and client, detailing in real-time every detail pertaining to your build from inception right through to handover.
You will never again feel out of the loop with your granny flat or dual occupancy construction project!
For your awareness, granny flats typically take 3-4 months to build, while duplexes and double-storey homes typically take around 7 months.
Factors like landscaping, weather, permit/inspection delays, and customisation can extend build durations by up to a month.
05
Once the final stage of the contract is realised, the final payment is calculated and any adjustments made, with full clarity. Before handover, Sean from Builders Brisbane will go with you through your new granny flat, dual occupancy, extension, or renovation and discuss any issues.
Once these issues are rectified and you are happy with the work, we hand over the keys.
The Building Services Authority (BSA) enforces a six-and-a-half-year warranty on the structure, which means you have full legal standing if you are not happy in the future, as well as Builders Brisbane's 100% satisfaction guarantee.

Frequently Asked Questions
Your Dual Occupancy & Granny Flat Investment Guide
From selecting the right design to watching your property take shape, each stage of construction is an important step toward creating your dream space. Generally, granny flats typically take 3-4 months to build, while duplexes and double-storey homes generally take around 7 months. Factors such as landscaping, weather, permit/inspection delays, and customisation can extend build durations by up to a month. We've put together a detailed guide we've put together a detailed guide to the typical build times for various buildings.
Investing in property can significantly help you achieve financial security and independence. By implementing dual occupancy strategies such as building granny flats or duplexes, you can create positively geared rentals, allowing your money to work for you. This proactive approach leads to massively manufacturing equity (with a potential $200,000 increase for strata titling), boosting rental yields (e.g., 10-12.5% on build price for granny flats), and significantly enhancing your borrowing capacity. As one broker advised, "every dollar you earn is $5 worth of loan that you can get," which helps immensely with serviceability. You can find out more by clicking this on this link.
Unfortunately, owners typically cannot use their own tradies for their project during the construction phase. This is primarily due to the builder's ownership and responsibility for the site, the crucial need to verify insurance, liability concerns, and financial implications with banks regarding stage payments. We care deeply for your build and want to ensure you get the best possible end product by managing all aspects of the construction. Read more on why that is the case.
There are many factors to consider, such as planning permission, design, budget, and construction. Key considerations include understanding local council regulations and zoning laws, especially since the Queensland Government removed usage restrictions on secondary dwellings on September 26, 2022, allowing them to be rented out separately. It's vital to adopt a site-centric design tailored to your block, choose quality construction (such as a brick and slab granny flat for durability and potential future strata titling), and anticipate fees like council fees or the need for secondary meters for independent power billing. We can guide you common mistakes to avoid for a smooth and successful project
