Step 1 - Free consultation

It all starts with an informal and obligation-free consultation. Our Design Consultants are there to listen and establish your requirements and expectations, and to offer guidance and advice. By the end of the consultation, you will better understand what is achievable and how much it is likely to cost.

Step 2 - Concept & Design Fundamentals

Once the scope of the work is agreed, we prepare a detailed Proposal for the scope of works as specified at this time along with detailed sketch plans of the design. The consultant will discuss any charges with you in advance and only proceed on your approval. (Note: The fee for this service varies based on the scope of work required and is payable directly to the Design Consultant).

Step 3 - Plans & Approvals

Upon your acceptance of our Proposal, we prepare detailed plans and arrange for an Engineer to certify that the existing structure will support the new work. Then once you have approved the plans, we submit documentation to your local council and other authorities, and arrange all the necessary approvals and inspections.

Step 4 - Building Contract

Cape Cod use the standard HIA NSW Residential Building Contract for RENOVATIONS & ADDITIONS, and provide a fully itemised specification of your project. Everything will be spelt out in detail so there are no hidden extra costs and no unpleasant surprises.

Step 5 - Construction

Before construction begins, we meet with you onsite to explain what occurs during the building process. Your construction supervisor is an experienced project manager and your personal building advisor. He will ensure that construction stays on track and that any difficulties are resolved without delay. During construction we offer a 24 hour, 7 days a week service hotline to assist you in case of any emergency.

Step 6 - Handover

Reaching handover is an exciting milestone and marks the completion of your project. During your handover appointment, we will walk you through your new spaces and answer any questions you have. While construction may be complete, our commitment to you continues and your Cape Cod extended 10 year structural warranty begins. .

We are the residents next door to where you have recently completed renovations. I just want to thank you for your kind letter and subscription gift. The renovations next door were really very little trouble to us at all. Please thank your team for being considerate during construction. I really appreciate your letter. It represents an unusual degree of consideration and care. Adriaan (Neighbour)

Having Cape Cod manage the design, approvals and construction made the whole process incredibly smooth. Our Design Consultant, Charles created designs that were practical, economical and aligned with our style, while our Construction Supervisor, Aaron kept everything running efficiently on site. We’re thrilled with the result. We have more space, more light and a seamless blend of old and new.

We decided to extend our home to create more space for our family while staying in the area we love. After discovering Cape Cod online and reading their consistently positive reviews, we felt confident they were the right choice – and they absolutely proved us right. From the very beginning, the process was clearly explained and professionally managed. Our Design Consultant, Ross developed a thoughtful design that introduced more natural light, improved storage and created functional new spaces that feel completely integrated with our original home. During construction, our Construction Supervisor, Rob was outstanding. He kept us informed at every stage, handled everything with ease and ensured the build was smooth and stress free. The finished extension blends beautifully with the existing house, and the upstairs retreat has become one of our favourite places to spend time. We couldn’t be happier with the result.
