ArchSolutioNZ Building Consent Specialists

    Paeroa rumpus renovation and enclosed deck building consent.

    Neville Williams wanted to bring a detached rumpus back into proper use and connect it to the home with an enclosed deck. The project needed old-plan reconstruction, 3D scanning, a new roof strategy, H1 upgrades, E2/AS1 moisture detailing, SED wind coordination and a clear council response pathway.

    Bottom line

    A detached rumpus and covered patio became a coordinated consent pathway, not a guesswork renovation.

    Start with the existing building. This Paeroa story shows why old plans, 3D scanning, site levels, roof geometry and technical detailing need to work together before council can confidently assess a habitable-space upgrade.

    Old property records were useful, but they could not be treated as the final source of truth.

    The starting point

    Old records, existing buildings and a design problem that needed evidence.

    The property had older plans, but the proposed work needed a modern building consent set. The existing house, detached rumpus, garage/storage space and covered patio all had to be understood before the new enclosed deck and roof strategy could be documented.

    The work was not just cosmetic. It affected the floor, walls, roof, cladding, insulation, weathertightness and council documentation pathway.

    3D scanning and site strategy

    The design was built from the actual site, not from assumptions.

    ArchSolutioNZ used 3D scanning and visual site markups to test the relationship between the existing buildings, roof lines, floor levels, covered patio and proposed enclosed deck. That gave the client a clearer design direction before the full consent drawings were prepared.

    How it was handled

    The consent package had to explain several connected technical issues.

    The real value was not a single drawing. It was coordinating the existing building evidence, design decisions, Building Code considerations, consultant inputs and council response pathway into a package that made the project assessable.

    Existing building captured

    Old plans were compared with 3D scan evidence so the existing house, detached rumpus, covered patio, roof levels and floor levels could be understood before design.

    Consent strategy developed

    The project was broken into clear consent issues: habitable-space upgrade, enclosed deck connection, roof form, raised floor, cladding and weathertightness.

    Technical details resolved

    E2/AS1 ground clearances, concrete nib detailing, H1 insulation, rafter design evidence and SED wind coordination were prepared for council review.

    Council responses organised

    RFI items were tracked against drawings, consultant inputs, product information and site evidence so the response could stay coherent.

    "We knew what we wanted, but we did not have the skills or knowledge to complete the design or manage the consenting process."

    From existing spaces to habitable use

    The old rumpus and covered patio needed a coordinated upgrade.

    The existing garage/storage area was to become a better rumpus space, while the covered patio became the connection between the detached building and the house. That meant the floor, wall and roof work needed to be coordinated, not treated as separate cosmetic changes.

    This is where a building consent specialist helps homeowners avoid a common trap: drawing the room they want without solving how the existing structure, moisture protection and compliance details will actually work.

    Moisture, wind and structure

    The consent strategy had to deal with the technical issues council would look for.

    The project needed more than a layout plan. ArchSolutioNZ coordinated E2/AS1 ground clearance thinking, a concrete nib detail, wind zone evidence, rafter design references and roof/wall flashing details so the existing building could be altered with a clearer compliance pathway.

    What council received

    A drawing set that explained existing, demolition, proposed and detailed work.

    The consent set did not rely on one big plan. It separated the story into existing conditions, demolition, proposed layout, roof, floor framing, elevations, sections and junction details so the assessment pathway was easier to follow.

    Council response management

    RFI responses were organised visually so the package stayed coherent.

    Council questions can become messy when drawings, details, product information, consultant input and site evidence are handled separately. For this project, ArchSolutioNZ used a visual workflow to connect each response back to the relevant evidence.

    That helped keep the consent response pathway organised instead of answering technical questions in isolation.

    "Alex managed the entire process, from submitting the consent application to responding to all council requests for additional information."

    Client experience

    Practical options, clear communication and budget-aware consent support.

    Neville's feedback repeatedly points to the same values: clear communication, practical advice, budget awareness, early problem solving and confidence through the building consent process.

    The family wanted most of the budget to go into construction, while still keeping the design and consent documentation strong enough for council review. That balance shaped the way the project was handled.

    The story above is based on Neville's written responses. The answers below have been lightly cleaned for readability while preserving the substance of the original client response.

    1

    What were you hoping to achieve with your project at 42 Claremont Avenue?

    We needed a plan and building consent to incorporate our detached rumpus room into our house. This required significant changes to the roof, walls and floors.

    2

    Before working with ArchSolutioNZ, what felt most stressful or confusing about the project?

    We were clear about the outcome we wanted, but the technical design challenges were well beyond our skills and experience. The building consent process was also very confusing, and we were unsure how to navigate it.

    3

    What concerns did you have about dealing with council, plans or approvals?

    Our main concern was the amount of information the council required. Because we were proposing so many changes, we were unsure what would be feasible from council's perspective and how much change would be permitted.

    4

    Why did you choose ArchSolutioNZ for this project?

    ArchSolutioNZ provided a comprehensive and competitive proposal. Alejandro was responsive, clear in his approach, and offered constructive, creative suggestions to help us achieve the outcome we wanted.

    5

    What made you feel confident that ArchSolutioNZ understood what you wanted?

    The initial on-site visit showed us that Alex understood exactly what we needed. The options and suggestions he provided also confirmed that he had the knowledge and experience we were looking for.

    6

    How did ArchSolutioNZ help turn your ideas into a clear plan?

    Throughout the process, Alex kept us informed about the design as it developed, sharing draft plans, drawings and material options. Communication was easy, clear and professional.

    7

    Did ArchSolutioNZ help you understand the design and consent process in a simple way?

    Yes. Alex explained each step clearly. Once we agreed on the general design, he brought in technical experts such as engineers and truss designers to complete the specialist work needed to meet council requirements.

    8

    How helpful was guidance through demolition, walls, windows, roofing and cladding decisions?

    It was extremely helpful. We knew what we wanted, but we did not have the skills or knowledge to complete the design or manage the consenting process.

    9

    Did ArchSolutioNZ help solve technical problems, not just prepare drawings?

    Yes. One of the most difficult issues was the roof pitch, as we needed to change the roof orientation and incorporate an enclosed deck. The final design was both practical and visually appealing.

    10

    How did ArchSolutioNZ help with council requirements and building consent approval?

    Alex managed the entire process, from submitting the consent application to responding to all council requests for additional information. We could see the progress through the council consent portal.

    11

    Was it helpful having someone coordinate the different parts of the project?

    It was essential and incredibly helpful, as we did not need to get involved in the day-to-day process. Alex managed and coordinated communication with the other parties involved on our behalf.

    12

    Did ArchSolutioNZ help you make good decisions about products and finishes?

    Yes. Alex shared different options and provided practical advice on the products needed for the project. We discussed the pros and cons of each option, and he gave recommendations based on experience.

    13

    Was keeping the project within budget important to you?

    Yes. We wanted to allocate most of the project budget to construction, while still keeping quality in the plans and consent process. In our view, Alex achieved both outcomes effectively.

    14

    Did ArchSolutioNZ help control costs or avoid unnecessary expenses?

    Yes. ArchSolutioNZ helped reduce costs in practical ways, including negotiating lower engineering costs and suggesting alternative product options for the construction phase.

    15

    Were there times when ArchSolutioNZ helped avoid mistakes, delays or rework?

    Yes. Alex helped us avoid mistakes and delays by identifying potential issues early and resolving them before they became bigger problems.

    16

    How would you describe the communication and support?

    Communication was very good. We stayed in regular contact by phone and email, and we felt well supported throughout the project. Alex was available at short notice to answer questions and provide updates.

    17

    Did you feel comfortable asking questions and raising concerns?

    Absolutely. The process was open, straightforward and easy to discuss at every stage.

    18

    Did ArchSolutioNZ make the whole process easier and less overwhelming?

    Yes. Having someone guide us through the design, technical requirements and consent process gave us confidence and removed a lot of the stress.

    19

    What was the biggest problem ArchSolutioNZ solved for you?

    The biggest design challenge was creating a roof profile that could join two semi-detached buildings under a single connected roof structure. The revised design was more elegant, practical and visually appealing than our first idea.

    20

    Would you recommend ArchSolutioNZ to other homeowners?

    Yes, we would happily recommend ArchSolutioNZ to other homeowners planning a renovation, garage conversion or consent project. They can expect personalised service, clear communication and a straightforward process that is easy to follow and understand.
