Common Questions
Site address, structure type, dimensions, and your timeline. The more detail the better. We'll ask if we need anything else.
Yes, on request for both structural and architectural packages. Defteng handles all design; the PS1 is signed by a CPEng (Chartered Professional Engineer) partner.
A simple pole shed or residential building: 5 to 10 business days from brief to completed drawings and PS1. Larger projects are quoted with a clear timeline.
Yes. We provide the full package: calculations, drawings, PS1, and NZBC compliance schedule, ready for your Territorial Authority.
Project-specific. Contact us with your brief for a fast, no-obligation quote.
Yes. We work with builders, developers, architects, and owner-builders. We communicate digitally, so it works the same for New Zealand and Australian projects.
