Minimising risks, maximising returns
Our process focuses on reducing risk and improving feasibility from the beginning. We help landlords and homeowners optimise the build potential of their land using practical, cost-aware design strategies that support long-term rental performance.
Granny flat development made easy via us
We support you end-to-end from feasibility through to consents and construction.
With Hevet Consultants involved (planning, architectural design, engineering, support where required), you’ll have an experienced team guiding the process and one point of contact for construction matters throughout the build.
Funding & finance procedure support available
If you need help exploring funding options, we can connect you with our partner mortgage broker — a specialist in property development and build funding, with experience supporting many TNC Construction clients.
Why add a new granny flat instead of buying another rental?
Adding a new secondary dwelling can offer:
• Strong tenant demand for modern, self-contained living
• Higher total rental income from the same landholding
• Lower maintenance and repair costs in the early years
• Better future resale appeal (added utility and flexibility)
• Builder warranty / workmanship guarantee
House plans designed to optimise rental revenue (up to 70m²)
TNC Construction specialises in investment-focused builds. Our granny flat and tiny home designs are created to maximise rental returns using land efficiently while delivering comfortable, modern living tenants value.
Whether you already own land or are considering purchasing, we can help you select the right design approach and deliver the project from start to finish.
