Built for Developers Managing Larger, More Complex Projects
Multi-unit and medium-density developments involve more than just building. They require careful coordination, experienced project management, and a builder who understands the complexities of planning, engineering, consultant coordination, and council compliance. Costas Constructions works with developers and investors who need a builder partner capable of handling that scale.

Hear From Our Customers
“Costas Constructions have done an amazing job on our 3 unit development from the planning stage to the completion and we wouldn’t be able to complete the build without them. I would highly recommend them for any multi unit development as they were professional in every dealing, very responsive and completed the build at high standard ahead of schedule. And the best thing was that every person we dealt with at Costas was extremely helpful, professional and knowledgeable.”
-Darko B
“We had the pleasure of engaging Costas Constructions to build our multi unit development. The team lead by George exceeded our expectations by delivering a high quality project that we are very proud of. The extensive experience by the team at Costas and their professional and personalised service made this a seamless process and a pleasure to deal with. The attention to detail and quality finishes also enabled our Property Manager to secure leasing in a very short timeframe. Thank you to the Costas Constructions team for delivering a high quality result and looking forward to our next build. Highly recommended!”
-Nick A
“George, Greg, Dale and all the staff at Costas provided excellent service from conception to completion. A four unit development that went without a hitch, was completed on time and the end result was of a very high standard. Every one at Costas was professional, communicative and always prompt in getting back to us with any queries we had. I can highly recommend Costas Constructions and will definitely be looking to have Costas complete more builds for us!”
