“Matt and his talented team undertook a huge renovation of our 100 year old cottage, turning it into a home fit for a growing family. The attention to detail was second to none and we felt in such good hands throughout the process. The complexities of rebuilding a home from the ground up, whilst ensuring the character features were well-restored and enhanced, didn't overwhelm the Rhombus team - they took everything in their stride. We are delighted with our newly renovated home - it's everything we wanted and more. We would highly recommend Rhombus for any building requirements.”

 Our Process


Pre-construction

We’ll have an initial consultation around what you want, your budget and how to align these two elements. We’ll discuss your expectations of time and schedule and guide you through the consent process. We can match you with an architect, draughtsman and engineer depending on your needs. We’ll then estimate costs and finalise details ready for your building project to start.

During the build

Ensuring that your experience is enjoyable and stress free we’ll communicate and involve you the whole way through the project. We’d like you to be involved with the building process and believe in working with you so that the finished product meets your exact requirements.

Post completion

Building a space for you to call home is an intimate process. We are privileged to be in a position to do this for you and value this relationship long after your project is complete. We are proud of our work and aim to be your life long building partner.

8 Steps to Renovation Success


  • We start by sending you a detailed discovery questionnaire to get a better understanding of your project needs, ideas, and vision. This will help us align with your goals and ensure a smooth process from the start.

  • Our team will conduct a free onsite consultation to further discuss your project, go through the questionnaire in detail, and document any specific needs and requirements you may have. This step allows us to create a clear pathway forward based on your ideas and requirements.

  • Engaging our professional services allows us to assist you with your plan development and budgeting prior to the start of your project. We will liaise with all consultants to ensure construction and cost efficiency allowing us to provide solutions for potential onsite construction challenges based on our vast project experience and knowledge. This investment will be absorbed into your build cost should you choose to move ahead with Rhombus Construction as your main contractor.

  • 4. DETAILED CONSTRUCTION PROPOSAL

    After plans have been developed, we will provide you with a detailed construction proposal that breaks down every aspect of our company and how we operate along with detailed costing of your project. We will engage our long standing and trusted sub trade team to provide quotes for your project. You will be able to take advantage of Rhombus’s trade discounts and specialty supplier rates. This will give you a clear understanding of the investment required for your build and help you make informed decisions moving forward.

  • We will arrange an in-person cost presentation meeting to go through the detailed breakdown and answer any questions you may have. This step ensures transparency and clarity in the cost estimation process.

  • Once the costs are finalised and agreed upon, we will take over the full project management of your build. Our team will ensure that every aspect of the construction process is handled efficiently and effectively.

  • We have a specific focus on quality to ensure that every detail is completed to the highest standard. This step includes our 200+ quality assurance checks so that each stage of the build is assessed thoroughly, leaving no disappointments.

  • Finally, we welcome you home and ensure that you are fully satisfied with the end result. Our team will address any final details or concerns, issue CCC and ensure that your experience with us has been positive and rewarding. Now that you are a part of the Rhombus family, we will be here for you long after your build is complete.
