Our Experience

We draw on 35+ years in residential construction to understand each step of the process intimately — from concept to occupancy.

  • Depth of hands‑on knowledge:

    We’ve overseen hundreds of projects across Greater Sydney and NSW, spanning one‑bedroom studios to two‑storey granny flats.

  • Diverse projects:

    We’ve handled everything from narrow or sloping sites to custom disability‑friendly designs and multi‑generation living setups.

  • Consistent results:

    Our track record proves we can reliably deliver on time, on budget, and to specification.

Technical Expertise

Your granny flat needs more than good aesthetics — it must comply with council rules, structural safety, energy standards, and site constraints.
Here’s where our specialist skills shine:

  • Permitting & approvals

      We stay up to date with New South Wales planning laws, local council codes, and development standards. We manage the approvals process so you don’t have to worry.

  • Custom design & engineering

      Our in‑house architects and structural engineers adapt designs to your block—whether flat, sloped, narrow, or constrained.

  • Quality construction practices

    We use reputable trades, high‑grade materials, and proven methods. Safety, durability, and performance are non‑negotiable.

  • Sustainable & efficient builds

      We prioritise energy efficiency, thoughtful orientation, insulation, and smart design to reduce ongoing utility costs.

This level of technical strength means your flat isn’t just built — it’s engineered to last and perform well.

Authority & Recognition

We don’t just claim quality — we’ve been recognised for it:

  • Multi‑award winning pedigree:

    We are one of only a few granny flat builders in NSW with multiple industry accolades for design, customer service, and innovation.

  • Hundreds of satisfied homeowners:

    More than 1,500 clients across NSW and Victoria have chosen us to build for them. (Source: company overview)

  • Media & features:

    Our projects and building approach have been featured in local publications, demonstrating our influence in the industry.

  • Referrals & repeat work:

Such recognition gives future clients confidence: you’re working with a builder known for excellence and consistency.

  • Trust & Client Focus

    We take seriously the responsibility of being chosen to deliver someone’s home — and we always aim to validate that trust.

  • Transparency & Accountability

    • We provide fixed‑price quotes so you can know the cost from the start.

    • No hidden extras: if adjustments arise, we explain and document them.

    • Regular progress reporting: you know what’s happening and why.

  • Client‑centred process

    • We listen first: your goals, constraints, lifestyle — we tailor the design around you.

What Sets Us Apart

Here’s how Granny Flat NSW distinguishes itself:

  • Speed without compromise:

    In optimal conditions, we can move from approval to handover in as little as 16 weeks

  • Tailored, not templated:

    Even when you like one of our standard plans, we adapt it — we don’t force you into a one-size-fits-all model.
