I would highly recommend COS Interiors; they were lovely to deal with, always prompt and on time to both the quote and the job. Our kitchens, laundries and bathrooms all looked fabulous once finished. We have used them multiple times now and wouldn't hesitate to use them again. Thank you so much COS for all of your hard work.


I started my professional relationship with COS Interiors in 2008 and they have since grown to form an integral part of my business. We market ourselves to very discerning clients and architects and therefore expect a lot from our sub-contractors. COS have delivered for me on all fronts. Builders are really only as good as their finishing trades and COS have always performed to the level that my clients expect. COS have a huge wealth of knowledge with materials, fixtures and fittings, and have been part of many projects with my architects at design stage to ensure every detail works and that design is never compromised.


We have worked with Luke and Adam at COS Interiors for a number of years (over two homes) and couldn’t recommend them highly enough. It was reassuring during the initial stages of a build that COS Interiors worked with our builders to ensure the structure was well planned and they impressed us with their ability to explain the benefits of the finishing’s we selected. The design consultation process was excellent in helping us develop our kitchen, bathroom and bedroom plans at a pace we were comfortable with. We honestly cannot fault the customer service and the finished product exceeded our expectations. A special thank you for your advice and communication throughout the process. All the COS staff we met on site were terrific (a big thank your office staff) for their prompt responses and their help with any queries we had along the way. Once again, we cannot thank you enough for a stress free renovation a quality built finish and having the house completed finished on time, as promised. Looking forward to the next one!


The team at Cos Interiors always deliver! They work collaboratively with me throughout the design and implementation phases to ensure all details meet and exceed my expectations. They source high quality materials such as the Calcutta marble for one of my kitchens, through to reclaimed hardwood timber for bathroom cabinets. After successfully completing four residential properties I am now working with them in the design stage of a commercial fit-out. in addition to delivering high quality and detailed finishes, they can always be trusted do the job when they say they will do it, and are reliable and punctual day-to-day.


We have been partnering with COS Interiors on numerous projects since 2015 to deliver exceptional joinery and custom furniture pieces. Collaborating with some of the best architects and interior designers, the team at COS have never let us down. As a small builder, our reputation depends on our sub-contractors and we know COS care as much as we do about delivering only the best.
