Architecture and Interior Design Practice in Melbourne


Quadrant Design Architects aims to provide intelligent, creative and cost-effective design and management for each project. The services that we provide can be all-inclusive or tailored to your specific needs or requirements.


Initial consultation is free and covers listening to and discussing ideas and budget for your project. We work with you to formulate the initial design brief, thus ensuring that this will give you the most intelligent design, tailored to your lifestyle and needs. Getting your brief right is vital to enable us to fully realise your project in a creative and practical manner. The formulation of the design brief creates the basis for a fee proposal for the project.



We provide independent advice on project contracts, tender process and negotiation. Assessment of tenders to ensure that comparisons are equitable and that a reasonable price range is obtained.



As your Architect, our service includes assessing the feasibility of your brief, budget and site as to whether it is appropriate to your wants and needs and also to suggest alternative options to create the best outcome. We can also help find the ideal site for your project, should this be required.



Registered Architects working in Victoria must have attained the necessary qualifications, completed practical experience and passed examination by the Architects Registration Board of Victoria.

Our broad range of experience and fresh approach can create exciting and innovative environmental options, for commercial or domestic projects. This service can be offered independently from our architectural service.

Our experience in this field ranges from imported iron cottages c 1847 to large mansions and restoration of country homesteads.

What Our Customers Have To Say

  • PMC
    I wish to compliment and thank you on the design, so many delightful features. It's attracting quite a lot of attention and looks superb from the beach road. The bungalow also is shaping up beautifully and looks quite charming. It's been a very enjoyable experience. The design also lends itself to some lovely choices, and character is reflected in every room. Well done!

    Brad and I would like to share some awesome news with you, yesterday our beautiful home was sold at auction. It sold well above our expectations and to say we are over the moon with the result is total understatement! While there are many factors which contributed to this great result it mostly had to do with the great house that you guys designed and built for us- we are so grateful that we managed to engage inspiring, talented architects and such professional, high quality builders. During the campaign we had lots of positive comments about the renovation and the standard of finish. Thank you to you guys and your wonderful teams.

  • L&L
    When we initially made enquiries about renovating our house, an Edwardian one, that had been modified in the 1960s, the only recommendation was to demolish and rebuild, which was not what we had intended to do with the house that had been in our family for 50 years. Luckily, we met Tony Jackson from Quadrant Design who was able to provide a more pleasing alternative: to keep our family home, renovating and restoring the Edwardian features of the existing house. From the start, Tony was full of enthusiasm and practical suggestions, which made us feel confident that we had made the right choice in engaging Quadrant Design. With their friendly, down to earth manner, Tony and his team made the planning process an enjoyable one. They were generous with their time, listening to what we wanted, presenting a variety of well thought out plan options, and ultimately designing the house we had envisaged. Thanks to Tony Jackson and his team, the family home is now a beautiful and elegant house which has received many compliments from family, friends, and complete strangers.

    I had been wanting to build an extension which would create a large modern living space in my 1930's house for several years, but two previous architects had said it was too hard and couldn't be done. Quadrant had a fresh approach and a "can-do" attitude, and was able to design a superb modern extension which addressed all my requirements. Quadrant also managed the project, contracting a builder who was prepared to think outside the box and incorporate some innovative design features, whilst dealing seamlessly with the inevitable unexpected quirks within the existing building. My visitors are astounded by the enormous two-storey window in the stairwell, the use of feature lighting, and the clever design of the project. Quadrant has created a magnificent living space which brings my home into the 21st century, without changing the ambience of the old house.

    We recently engaged the services of Quadrant Design to create a new space for our growing family. This was a big project for us and we were looking for an architect with whom we could work closely to create our dream home. Quadrant Design was very skilled at bringing our ideas to life, exploring different options and most importantly keeping within our project budget. Whilst ensuring that our practical design needs were met with functionality, Quadrant Design created a space that is truly breathtaking, maximising our beautiful views. The design compliments our existing house and makes full use of natural light. Jono at Quadrant put his very best effort into our design. At one stage during construction he phoned us, saying he had a sleepless night thinking about the design of our roof. He had been thinking that a tapered roof would look even better, which we agreed and once it was completed realised that it was a very smart, creative and relatively inexpensive variation to our plan. We would highly recommend Quadrant Design to anyone looking for an architectural firm that is creative, efficient and goes the extra mile to ensure that the project is the best that it can be.

  • Peter and Sheila
    Quadrant Design from the start were able to comprehend our vision for our extension and take this concept through to the completed project. Their willingness to listen to our desires and concerns, explore the possibilities and present us with well thought out options resulted in the blending of our original house with the additional spaces we required, producing a home which we love living in and are proud to show off. We were seeking something more than a four walled extension and Quadrant achieved this beyond our expectations, incorporating some unique features and special touches that set our home above the norm. We found Tony and his team at Quadrant easy to work with and very enthusiastic in helping us get the home that we wanted.
