    Concept Design to Building Consent

    A simple step-by-step guide explaining how ArchSolutioNZ takes you from first enquiry and free guidance to concept design, revisions, final sign-off and a transparent building consent quote.

    Quick Answer

    Use this guide before starting design. It explains what information we need, when a 3D scan may be required, how concept options are prepared, how revisions work, and how the concept package becomes the base for the building consent stage.

    Feasibility comes first
    Two revision rounds included
    Consent quote comes after sign-off
    Step 1

    Contact Us or Use the Free Project Tools

    Your project usually starts when you contact ArchSolutioNZ, use a project tool, or send a message through the contact form. At this stage, you do not need to know the correct consent pathway.

    • Send your idea, address, photos, drawings, council notes or project description.
    • We review the information and give initial guidance on the likely pathway.
    • We explain the overall process from concept design to building consent so you know what happens next.
    • If the project is not ready for concept design, we point you toward feasibility, council support, CoA or another pathway.

    The first conversation is about direction, not locking you into a design package before the project makes sense.

    Step 2

    Share Property Details, Photos and Existing Records

    Before we price or start the work properly, we need enough information to understand the existing property and the design problem.

    • Send your property file, Record of Title, existing council drawings, surveys, photos and previous reports if you have them.
    • If plans already exist, we review whether they are accurate enough to become the base for design.
    • If the plans are incomplete, old or unreliable, we explain what extra information is needed before design starts.
    • We also ask about your preferred budget range, must-have items and what problem you want the project to solve.
    Step 3

    Initial Feasibility, Planning and Risk Review

    Before design becomes expensive, we carry out an initial feasibility review to identify the big risks and avoid designing something that is unlikely to work.

    • Planning and site checks, including zoning, overlays, flood hazards, wind zone, resource consent risk and Schedule 1 possibilities.
    • Design and cost checks, including structural implications, existing wall, roof and foundation constraints, likely consultants and practical material or layout options.
    • Early pathway advice so the project can be redirected before time is spent on the wrong design direction.

    Feasibility checks at concept stage are preliminary. They help identify risk, but they do not replace specialist reports or council decisions.

    Step 4

    Scope of Work, Contract and Project Start

    Once the project direction is clear enough, we prepare a scope of work and place it into a contract for services.

    • We define what is included in the concept design stage.
    • We identify what is excluded or may require extra fees, such as 3D scanning or specialist reports.
    • You receive the contract for services and the first invoice.
    • Once the contract is signed and the first invoice is paid, the project officially starts.

    The concept stage is separate from the later building consent documentation stage.

    Step 5

    Prepare Existing 2D Plans, 3D Model or 3D Scan

    The concept design needs a reliable base. If existing plans are available and accurate enough, we convert them into clean 2D and 3D information so design can begin.

    • If usable plans exist, we prepare the base drawings and 3D model from the available information.
    • If the house is old, altered or missing council records, we may need to measure and 3D scan the property.
    • 3D scanning collects accurate existing-condition data so the plans and model are not based on guesswork.
    • The scanning fee is treated as an additional service when required.

    3D scanning is usually needed only when existing plans are unavailable, too old, unreliable or the project needs accurate existing conditions.

    Step 6

    Define Your Requirements and Design Brief

    We confirm the brief before producing concept options. This helps avoid wasting design time on layouts that do not match your real priorities.

    • You complete or discuss a brief covering goals, functional preferences, family needs and budget range.
    • We clarify what is essential, what is optional and what can be simplified if cost becomes an issue.
    • We discuss cheaper, medium and more expensive design or material directions where useful.
    • We review whether the brief creates structural, planning, consent or cost implications.
    Step 7

    Concept Planning Options

    We prepare concept planning options so you can compare possible layouts and design directions before committing to building consent documentation.

    • Depending on the project, we may present one to three layout concepts or design variants.
    • Options may include plans, sketches, diagrams and 3D views to help you understand the design.
    • We try to minimise structural impact where possible to help manage construction cost and consent complexity.
    • If a design direction appears to require major structural work, we explain the likely impact and where engineer input may be needed.

    Major structural decisions are coordinated with an engineer during the relevant stage; concept design helps identify where that input is likely.

    Step 8

    Choose and Refine Your Preferred Concept

    You choose the preferred concept and we refine it with you. The goal is to reach a design direction that you are comfortable taking into the building consent stage.

    • Two free revision rounds are included in the concept stage.
    • Revisions refine the chosen concept and are not a complete redesign from zero.
    • Most clients are satisfied after the first or second revision.
    • If more changes are needed after the included revisions, we agree on a revision fee before continuing.

    Major scope changes after the design direction is approved may need a new quote.

    Step 9

    Final Concept Sign-Off and Building Consent Quote

    Once you review the final revision and confirm that no further changes are required, the concept design stage is complete.

    • The approved concept becomes the base information for the building consent stage.
    • We prepare a transparent quote for building consent documentation and identify likely consultant requirements.
    • If you proceed with ArchSolutioNZ for the building consent stage, the concept work can reduce duplicated effort.
    • The building consent stage then becomes a separate fixed-fee service with its own scope, contract and documentation process.

    Concept drawings are not construction documents. If your project requires building consent, construction should not start until building consent has been granted.

    What We Check During the Initial Feasibility Review

    The concept design stage is not just about drawing options. It is also where we test whether the idea is realistic before time and money are spent on the wrong direction.

    Zoning and overlays
    Flood hazards or other mapped hazards
    Wind zone and exposure
    Resource consent risk
    Schedule 1 or exemption possibilities
    Structural impact of the idea
    Possible engineer involvement
    Material, layout and cost alternatives
    Likely consultant requirements

    Common Questions

    Do I need existing plans before concept design?

    No, but they help. If there are no reliable existing plans, we may need to measure or 3D scan the property to prepare accurate existing drawings before concept design starts.

    How many concept options do I get?

    Depending on the project, we usually provide one to three concept options or variants. Simple projects may only need one strong direction, while more complex projects may benefit from comparing alternatives.

    Are revisions included?

    Yes. Two free revision rounds are included to refine the preferred concept. A full redesign or extra revision rounds can be provided for an agreed additional fee.

    Can I build from concept drawings?

    No. Concept drawings are for design decisions and pricing direction. If your project requires building consent, construction should not start until building consent has been granted.

    What if the concept triggers resource consent risk?

    We advise you during the early feasibility review if the project appears to trigger planning or resource consent risk, so you can decide whether to adjust the concept or seek planning advice before moving forward.

    Ready to turn your idea into a clear concept design?
