    Choose the right Brisbane house designer

    Don’t risk wasting time and money on plans that are hard to build or won’t get approved!

    Some building designers focus only on creative drawings — leaving you to navigate council approvals, builder quotes, and design changes alone. We design with construction in mind from day one, making sure your plans are practical, compliant, and ready to build — saving you from costly delays, redesigns, or setbacks down the track.

    Choosing the Right Brisbane Building Designers Makes All the Difference

    When you’re planning a renovation or extension, it’s not just about getting drawings on paper — it’s about making smart decisions early that save time, money, and stress later. You need a building designer who understands how to bring your ideas to life in a way that’s practical, compliant, and buildable.

    We’ve worked with many Brisbane homeowners who came to us after spending thousands on plans that weren’t viable — either because they didn’t suit the existing structure, blew the budget, or stalled during the approval process. Our goal is to prevent that from happening to you.

    Here’s how we help:

    Specialists in Renovations & Extensions

    5 customer reviews for our drafting services and building design services

    Thomas Clarke

    ADG have helped me build and design my dream home. They were super efficient and had great communication. We were always kept up to date with progress and were very lenient with our suggestions. ADG refuse to cut corners and are willing to spend more time and money to ensure everything was done professionally and according to the AS. 10/10. Would recommend to anyone wanting to renovate. Thank you so much to ADG and their responsive, friendly, experienced team

    Herodotos Karalouka

    From the initial design consultation, to the finished product, I cannot recommend Alex and the team at ADG Construction highly enough. Their industry knowledge and quality workmanship are second to none. I will certainly be using ADG again for my next renovation and will not hesitate to recommend them to my friends and family.

    Marco Currenti

    We closed in our garage and rumpus and turn it into an additional 3 bed 2 bath home. Alex was very experienced, has a heap of great ideas and kept us in the loop with any changes. We didn’t know where to start but Alex helped through the entire process including design. Very happy with the outcome and the value added to the house.

    Callum Wishart

    I provided ADG with a tough design and they surpassed my expectations - would highly recommend for any construction job. Very friendly service as well

    Brisbane Building Design FAQs

    Do you offer staged design packages?

    Yes — we can tailor our building design process to suit your project and budget. Whether you’re looking for initial concept plans, council-ready documentation, or a complete design-to-build solution, we’ll customise a package that works for you. This is especially helpful if you’re still deciding how far you want to take your renovation or extension.

    Can you design decks and pergolas?

    Absolutely. We offer building design for decks and pergolas that complement your home and enhance outdoor living. Our plans ensure your structure is compliant with Brisbane council regulations, and we can also complete the construction if you’re after a seamless design-and-build experience.

    What’s the difference between a building designer and an architect?

    Both can design homes and prepare documentation, but architects are typically used for large-scale or complex projects and often come with higher fees. A building designer is ideal for renovations, extensions, and custom residential work — offering creative, compliant, and cost-effective solutions. We specialise in practical designs that are ready to build and tailored to your existing home.

    How much does building design cost in Brisbane?

    The cost of building design in Brisbane can vary depending on the size and complexity of your project. For most renovations and extensions, you can expect to pay between $3,000 and $10,000+ for full design and documentation. We offer flexible, staged packages that suit different budgets — and because we also offer construction services, we make sure your plans are realistic and buildable from the start, saving you time and money on costly revisions and project delays.

    Do you handle council approvals and building applications?

    Yes, we take care of the entire process, including preparing and submitting your plans for Development Approval (DA) or Building Approval (BA) where required. As experienced building designers in Brisbane, we understand the local council requirements and can manage the application process on your behalf. This helps reduce delays, avoid compliance issues, and ensures your project stays on track from the start.

    Can I make changes after the initial design?

    Yes, we allow for design revisions as part of the process. It’s normal for homeowners to refine ideas after seeing the first concept. We’ll guide you through feedback rounds to ensure your final design is aligned with your vision, budget, and site conditions. Our goal is to get the design right before moving on to approvals or construction.

    Do you offer building design for new homes?

    Yes, we provide practical and cost-effective house design for new homes across Brisbane. So if you’re looking for custom home designs brisbane — you’ve come to the right place!

    We create custom house designs and house plans as the first step to turning your vision of your new home into concrete reality. Whether you’re planning a custom home, knockdown rebuild, or investment property, we create council-ready plans that are functional, buildable, and tailored to your site and budget.

    As a full service design and construction company we can also liaise with the council on your behalf to get your project approved and conduct the construction work. Simplify your project and achieve a faster more cohesive result with one competent company taking care of the entire project from design to construction.

    Do you offer staged design packages?

    Yes — we can tailor our building design process to suit your project and budget. Whether you’re looking for initial concept plans, council-ready documentation, or a complete design-to-build solution, we’ll customise a package that works for you. This is especially helpful if you’re still deciding how far you want to take your renovation or extension.

    How long does the building design process take?

    For most renovations, extensions, and granny flats, the building design process takes around 2 to 6 weeks, depending on the complexity of the project and how quickly decisions are made. This includes concept development, client feedback, and preparing documentation for council submission. Because we understand Brisbane’s local regulations, we can move faster and help you avoid unnecessary delays — keeping your project moving forward on schedule.

    Do you offer staged design packages?

    In most cases, they’re the same. The term building designer is the official title used in the industry, while house designer is a more general term that homeowners often use when searching for residential design services. E.g. they may Google house designers Brisbane to find relevant local professionals. As experienced house designers in Brisbane, we focus on practical, buildable designs for renovations, extensions, and custom homes — always with council approval and construction in mind.

    When should I engage a building designer?

    It’s best to engage a building designer as early as possible — ideally before you speak with builders or apply for approvals. Starting with a well-thought-out design ensures your plans are practical, buildable, and aligned with your budget. It also helps avoid costly revisions down the track. Whether you’re planning a renovation, extension, or granny flat, early design input sets your project up for success.

    Can I bring my own builder or do I have to use yours?

    We’re a fully licensed design-and-build company, so most clients choose to continue with us for construction once their plans are finalised — it’s a seamless way to keep everything under one roof. However, if you’re only looking for design services or already have a builder in mind, we’re happy to provide plans and documentation that they can work from.
