The Process – Custom Design

  • Design Consultation

    When your ready to start the journey towards your new home make contact via phone or email and we will book a time for a face to face consultation. We can meet on your piece of land or in our office. We will have a relaxed chat and get a feel for your vision, requirements, budget and begin working on a comprehensive design brief.

    If you want help refine your design brief check this link

  • Design Contract

    Once the Design Brief is finished we can provide you with a fixed price contract for your design and working drawings. This price will be for a full set of working drawings finished to a stage ready for council submission for building consent. Once this contract and the designs are complete you will have full ownership of your plan set. You be required to make a deposit at the time of signing the contract.

  • Design

    Now that the acceptance of the contract is complete work will begin on the plans and working drawings, this is a 4 Stage process including Stage 1 - Pre Design, Site Visit & Site Analysis, Stage 2 - Concept Designs, Stage 3 - Preliminary design, and Stage 4 Developed Design. You will be actively involved in the design and will be kept informed throughout the entire process.

  • Construction Contract

    Once the design, working drawings, and costings are complete we will present you with a fixed price contract for the build. You will enter into a Registered Master Builder contract.

    The contract outlines the fixed costs, payment structure, and and a whole lot of valuable information to help protect both you as the client and assist us in running a successful business.

    You will also be provide with detailed specifications and inclusions to ensure you are informed and your budget is not compromised.

    The contract acts as a legal agreement between you and Cassa Building & Design Ltd. Upon signing the contract document you will also be required to make a deposit.


  • Construction Consultation

    Before the fun part begins you will have the final pre construction consultation where the finer details of the build are confirmed such as colour schedules for the joinery, roof, and paint colours. Our project manager will explain the construction process of your new home to you in detail before work begins.

  • Construction

    Construction of your new home will be overseen by Andre Mayo of Cassa Homes acting as project manager. You will be kept informed throughout the build by way of planned site visits, email updates, phone calls, and progress photo updates.

    During the build Cassa Homes will comply with all building code and regulatory requirements as well as regular quality assurance checks by the project manager and qualified site foreman.

  • Completion

    Once construction is completed and the necessary council inspections signed off, Cassa Homes will action 'Practical Completion' and initiate the '10 Year Master Builder Guarantee'. Your Code of Compliance Certificate application will be submitted and hand over can begin.

    We will arrange a date for you to move into your home, help you settle in and arrange a final hand over quality checklist is completed with one of our Foreman. You will then be presented with a gift basket and the Keys to your new home.

What our customers say about their Cassa Home.

  • Our Stunning Waterways Home

    Our Stunning Waterways Home

    Our dream was to build a home which complemented our outdoor / indoor style with entertaining and open plan as important features. We had decided on a floor and design plan that involved my wife and I having a significant role in the interior fit out and components of the exterior. From the outset, Cassa Homes made positive and sensible recommendations and offered sound advice and cost effective options to our ideas.

    Andre was always receptive to our involvement and was a solution provider when required. He was easy to work with and had a quiet manner and ability to listen to any concerns that arose. He is methodical and has an excellent rapport with his team of subcontractors. He also relates well to exterior contractors that were not part of his every day team of tradesman.

    Our home was completed within agreed timeframes and the quality of finishing work has been outstanding. Andre was always responsive to meeting requests, questions and any issues that arose and continues to keep in touch with us as minor issues or questions arise. We are delighted with the final product and look forward to a long and enjoyable lifestyle in our stunning waterways home.

    My experience with Andre and his team has been positive from the start of the build to its conclusion. They built me a beautiful and solid family home that I am very pleased with.

    Andre and his team were amazing! We had complete faith in the whole process, which was vital as we were building in Whitianga whilst living in Auckland. They built the house of our dreams, and if ever there was a problem, Andre always had a solution.

    Dream Home

    We had the pleasure of having “Cassa Homes” build our “dream home” in 2015/16. The whole experience from start to finish was fantastic! Andre Mayo was an exceptional builder to work with. He was honest, reliable and well organised, and his calm nature made any issues easy to resolve. For our home, his workmanship and attention to detail was excellent, as was his expectations for the performance of all the sub-contractors. We are thrilled with the final result and thank Andre and his team for a job well done!

    Major Restoration

    We had a difficult project involving the major restoration of our family beach house. We realised we needed a special relationship with a builder based on trust and flexibility. We had a tight budget and efficiency was critical. Andre and his team was recommended to me and he brought along an excellent selection of subtrades. I must say we are very pleased with the outcome.
