Simple Guided Process

I have had the privilege to work with Darren from Group One Construction. As a subcontractor it is nice to know when you arrive to a job site knowing the place is ready for you and everything is done correctly. There are no shortcuts taken and all work is completed to the highest standard. I recommend Group One Construction for all my customers that are in need of a general contractor.

Living in Adelaide and having a major renovation on Barack Street has been stress free having Darren and his team in control. The workmanship constant feedback and caring about the result and costs have been a credit to Darren and the team. I would not hesitate in recommending them.

Group One Construction came recommended to me by Defreitas and Ryan Commercial as an up and coming quality Builder. Darren does not disappoint. His communication skills, expertise in the building industry and trades team are to be commended. Darren works closely continuously providing updates, solutions with the aim to achieve great results and impress the client. This is my ninth commercial build and I would be very happy to be do number 10 with Darren.
