Our Renovation Designs Focus on You and Your Family

Although our architects have extensive experience renovating a wide variety of homes, our true specialty lies in designing spaces that reflect your lifestyle and the way your family lives. Our residential architects and interior designers bring decades of combined experience – ensuring every renovation is tailored to enhance comfort, functionality, and enjoyment. Our architects understand the importance of creating a home which feels uniquely yours – one that supports your daily life and evolves with you. To achieve this, we always consider three essential elements when planning your home renovation:

Great Design is Woven
into Every Project

Our architects believe that every renovation should respect the character of your original home. That’s why they thoughtfully consider both the elements you love, and the features you’d like to change. Our architects work to seamlessly blend these design goals into a cohesive aesthetic that suits both your lifestyle and your budget. At dion seminara architecture, we believe that a well-executed renovation doesn’t always require dramatic transformation. Sometimes, a carefully considered refinement delivers the most meaningful impact.

The Needs of the Customer
are Always at the Forefront

Our architects believe that your home is your sanctuary – a place to unwind, recharge, and live life on your own terms. That’s why our renovation designs always account for your privacy, lifestyle, and how you wish to experience each space. Whether your goal is to maximise outlooks or create private retreats, our architects tailor every detail of your renovation to support your way of living, ensuring a home that is both beautiful and deeply personal.

Our Clients Bring the Need, We Bring the Know-How

Our architects listen closely to what you need from your renovation, and then bring that vision to life. Our renovation architects have decades of experience delivering thoughtful, budget-conscious designs that feel bespoke and effortless. Every detail of your renovation is planned to ensure your new spaces integrate harmoniously with the existing home, resulting in a renovation that enhances both function and feeling.

Client Testimonial

"We have been meaning for some time now to put in writing our appreciation and thanks for Dion’s creative but yet very practical architectural input to the renovations that we undertook at our home during the latter half of 2001. We continue to be amazed at the practicality of the design. We are so pleased with what has been achieved. Dion took an ordinary brick box and created a modern, contemporary styled home suited to the lifestyle we envisaged, namely, comfortable living and entertaining, both indoors and outdoors. We are grateful to Dion for that. In short, our experience with Dion Seminara as our architect and the subsequent activity of our renovations have been most enjoyable and successful, a situation which is not always the case, if one is to believe “conventional wisdom” and anecdotes about designing and building a house."
Trevor & Anne
"Over the past two years we have been working with Dion Seminara to modernise our solid 1980′s brick home. The result is a modern open plan house that capitalises on a bright north-easterly outlook and is now a delight to live in. We were introduced to Dion as a result of inquiries at Australian Institute of Architects. After describing what we wanted, Dion led us through various stages of concept design and design development and eventually managed the building contract for us. We had some of our own ideas for improvement to the house, but Dion took the renovations way beyond out initial expectations to end up with the great result we now have. His experience and flair for this type of work meant that the fittings and fixtures complement the improvements he made to the overall house design through the tender process, his recommendations on builder selection and the contract negotiation process led to a quality product. We would recommend Dion to anyone wanting design and project management assistance to renovate and modernise their home. We would be pleased to provide further information or to discuss this with anyone interested in using Dion’s services."
Robin & Carolyn
"When we approached Dion, our scope was to open up the back of the house to make the area flow through from the inner living to the outside. Also in the process, we wanted to modernize the kitchen and as with all projects, we also extended the scope to include the main bathroom upstairs. What we have achieved is a very liveable area that flows with a modern workable kitchen. On Dion’s recommendation, we changed the orientation of the kitchen by extending into what was previously a walkway. I now have a study on the ground floor as recommended by Dion as my original study was upstairs away from the main living area and this new study is well utilized due to its location. We are very happy with the renovation as designed by dion seminara architecture."
