Duncan Thompson Extensions has over thirty years' experience in building and renovating homes in Melbourne's inner, eastern, south-eastern and bayside suburbs.

Unlike other construction companies, Duncan Thompson Extensions focuses solely on house extensions and renovations. It is this focus that has led to us becoming one of Melbourne's leading builders and renovators. As an experienced home builder, Duncan Thompson Extensions has developed a reputation as a quality renovator and reliable home extension company. We are one of the best Home Renovation Builders servicing in Melbourne, Hawthorn, Brighton East, Camberwell, Surrey Hills & Glen Iris.

We specialise in all types of housing renovations. A good quality renovation should complement the best aspects of a house, and it takes a builder with a combination of high quality skills, knowledge and experience in order to achieve a quality extension. That is why we employ only the most skilled and experienced builders and tradespeople to bring out the best in your home. Our renovation builders have provided the amazing renovation services in Melbourne.

Dedicated design & build teams

Many other renovators and builders source outsiders to do their design work. We do not believe this is an effective way of working because it causes designers and builders to lose touch with a project, and could sometimes even end up being costly to you. At Duncan Thompson we employ all our own design and construction staff. This allows a more intimate knowledge of your renovation needs, at all stages of the project, and also helps to avoid costly mistakes.

Our emphasis on quality

Home extensions are our passion at Duncan Thompson Extensions, and we will stand by the quality of our work. We believe in what we do and offer above industry standard guarantees on all our work, as well as fixed price contracts to help offer you peace of mind.We work with you from concept to completion to help build your renovation ideas into a reality.
