Melbourne's trusted granny flat builders & conversion specialists
Expert Granny Flats & Garage Conversions Melbourne
At Kevin Quach Property Group, we specialise in designing and building granny flats and garage conversions across Melbourne — helping homeowners unlock the full potential of their property by adding a self-contained living space that generates rental income, accommodates ageing parents or adult children, or creates a dedicated home office, studio, or guest accommodation. Whether you’re looking to build a new detached granny flat in your backyard, convert an existing single or double garage into a fully loveable space, or transform an underused room or studio into a self-contained dwelling, our licensed builders manage the entire project from concept design, planning permit applications, and council approvals through to construction, fit-out, and final inspection — giving you a stress-free, end-to-end build experience.

Recent Granny Flat & Garage Conversion Projects
Every granny flat and garage conversion we build is finished to a high residential standard — using quality framing, insulation, flooring, joinery, fixtures, and appliances that make the space genuinely comfortable and liveable for the long term. We design each build to maximise natural light, ventilation, and functional layout within the available footprint, ensuring the finished space feels spacious and well-considered rather than like an afterthought. Whether the space is intended for a paying tenant, an elderly parent, or personal use, we build it to the same standard — durable, well-insulated, energy-efficient, and compliant with all relevant Victorian building codes and the National Construction Code. Browse our recent granny flat and garage conversion projects across Melbourne to see the quality of our work firsthand.

Custom Design, Council Approvals & Complete Build
Our granny flat and garage conversion service is fully end-to-end — meaning we handle every stage of the project so you don't have to coordinate multiple contractors or navigate the planning system alone. We begin with a detailed design consultation and feasibility assessment to determine what's achievable on your block under Melbourne's local council regulations and Victoria's ResCode requirements. From there, our team prepares and lodges all planning permit and building permit applications, manages the full construction program including all licensed trades — carpentry, plumbing, electrical, plastering, tiling, and painting — and handles the final building inspection and occupancy certificate. We also offer guidance on secondary dwelling regulations, owner-builder requirements, and rental yield expectations to help you make the most informed decision before committing to your project.

Granny Flats & Conversions That Add Real Value to Melbourne Properties
Kevin Quach Property Group has helped Melbourne homeowners across the inner suburbs, eastern suburbs, and south-east corridor build granny flats and convert garages into self-contained living spaces that deliver genuine, measurable returns — whether through weekly rental income, increased property valuation, or simply the lifestyle benefit of having family accommodation on-site. We understand that a granny flat or garage conversion is a significant investment, and that navigating Melbourne's planning system, managing a multi-trade build, and ensuring the finished space meets all compliance requirements can be overwhelming without the right team. That's why we take full ownership of the process from day one — keeping you informed, protecting your budget, and delivering a finished build you'll be proud of for decades to come.
