How We Work

Design, Working Drawings, Permits and Engineering, Assurances, Contracts & Construction

What’s the secret of our success over the past since 1994? It could be our process that keeps the project moving forward in a logical manner for our clients. We start at the top with design, where we listen to all your dreams and preferences for your extension. Then based on our agreement with you in that step, we create working drawings for our builders. We do all the liaising necessary with your council to sort out permits and engineering requirements. Our assurances certify the standard of the work you can expect. After soil testing the area, we invite you to sign on to the second half of the contract, where the most exciting part starts – construction. If you have any questions throughout any part of our process, you can ask your dedicated project manager.
