Build from your plans process.

At Allen Brothers Construction, we’re not just focused on building exceptional homes—we’re focused on building trust. With over 50 years of combined experience, we’re proud to deliver honest, high-quality construction services across Brisbane and surrounding areas.

If you already have plans, our Build from Your Plans process is designed to take you from documentation to handover with clarity and confidence. We’ll guide you through each stage of the build process, with open communication and a commitment to quality at every step.

Our team works closely with homeowners, designers, and consultants to ensure your vision is realised—on time, on budget, and to the highest standard.

  • You’ve reached out and received our project questionnaire. Once completed, we’ll arrange a meeting (either onsite or at our office) to dive deeper into your vision.

    We’ll discuss buildability, answer your questions, and explore what matters most to you. For renovations, we’ll also inspect the property and gather key details.

  • Using data from past projects, we create a tailored preliminary budget estimate for your build. This high-level figure helps assess whether the project aligns with your budget before detailed pricing begins.

    At this point, plans aren't shared and trades or suppliers aren’t yet involved.

    We’ll also review a preliminary agreement to move forward with a formal tender. A fee of 0.35% of the estimated project cost applies at this stage.

  • With all documentation in hand, we begin detailed pricing using our in-house estimating software. We combine internal estimates with tenders from trusted subcontractors and suppliers to determine the proposed contract price.

    This process typically takes 4–6 weeks, depending on project scope and industry conditions.

  • We’ll present the Works Proposal for review and discuss whether to proceed as quoted or explore value management options to reduce costs.

    A draft contract will then be issued, using either a fixed-price (RBC-L2) or cost-plus (CPC-L2) Master Builders contract, depending on what suits the project best.

  • Once the contract is signed, a 5% deposit invoice will be issued. Upon payment, we’ll lodge the QBCC Home Warranty Insurance and the QLeave Portable Long Service Leave Levy, then provide proof to the certifier to release building approvals.

    If a certifier hasn’t already been appointed through your designer, we can assist with this step.

  • Construction begins. With our comprehensive job management system and client portal, you’ll have full visibility and confidence throughout the build.

    We’ll guide you through how it all works so you know exactly what to expect at every stage.
