SQ Architecture is an Architectural Design practice based in Brisbane and the Gold Coast, Australia. We specialise in small to medium scale projects ranging from residential to commercial developments. We are committed to making life better through design and our strength is our ability to explore, communicate, collaborate and apply our wide knowledge to help create the project you desire. 

If you are looking for a practice to push the boundaries or maximise your yield then SQ Architecture is for you. We love to test all your options and will provide you with practical, realistic, thoughtful and informed possibilities for your project. As we are a small practice, it enables us to provide competitive pricing while still maintaining an exceptional level of service and quality Architectural Design. 

Our Director, Ian Elphinstone, will be with you from concept through to completion and will help you navigate through the complex world of approvals and construction to help deliver the project you desire. We have invested our time and money in keeping up with the latest construction techniques, materials and regulations to provide the best advice possible for your project. We also run the latest software which allows our clients to interact with the project through the design phase. We can send a 3D file that can be opened on any smart phone or tablet device so you can walk or fly around your design before turning any soil. 













If you would like to talk about your projects potential please contact us on the details below. We look forward to hearing from you. ​
