What is a granny flat?
A granny flat is a self-contained second dwelling built on the same lot as your existing home. It offers genuine independent living, with its own kitchen, bathroom and toilet, while remaining subordinate to the main house. Officially recognised as secondary dwellings, granny flats give families a flexible way to live close together while everyone keeps their own space and privacy.
That flexibility is exactly what makes them so popular. A granny flat can adapt as your family’s needs change, serving one purpose today and another a few years down the track.

Why build a granny flat?
For many homeowners, a granny flat is the smartest way to solve a space problem without leaving the home they love. The benefits are hard to beat:
- Multi-generational living. Keep ageing parents or adult children close by, with comfortable, independent accommodation of their own.
- Rental income. In many areas you can rent your granny flat, including to people outside your family, creating a steady second income.
- Added property value. A quality granny flat can enhance your property value significantly and appeal to future buyers.
- Flexible space. From a guest space to a private retreat for the family, a granny flat flexes to suit your life.
It’s extra space, extra options and extra value, all on the land you already own.
Modular Granny Flats for a Faster, More Efficient Build
Modular granny flats are designed to make the building process faster, cleaner and more efficient, with less disruption to your property. With a streamlined construction approach, your granny flat can be planned around your site, lifestyle and long-term goals while still delivering a high-quality secondary dwelling.
Small Granny Flats for Compact Blocks and Flexible Living
Small granny flats are ideal for homeowners who want to make better use of limited backyard space without overwhelming the property. A compact design can still include the essentials for comfortable everyday living, making it suitable for family accommodation, guest stays or future rental potential.
Granny Flat Builders You Can Trust
As experienced granny flat builders, we believe your granny flat should be built to the same standard as the family home it sits beside. We work closely with you from your very first idea, with one expert team looking after the entire process, including design, approvals, construction and handover.
Being a family-owned and operated business means we genuinely care how the final result turns out. You’ll deal with people who take pride in their craft, communicate clearly and treat your project as if it were their own, with transparent pricing and no surprises.
Planning, permits and council requirements
Granny flats must comply with local council regulations and planning standards, and a building permit is generally required before construction begins. The good news is the rules are often more straightforward than people expect in many areas, a small secondary dwelling can be built without a separate planning permit, with maximum floor areas commonly restricted to around 60m² to 80m² depending on your council.
There are a few non-negotiables: a granny flat must sit on the same lot as your existing home and include its own kitchen, bathroom and toilet. Because requirements differ from one council to the next across South East Queensland and Northern New South Wales, our team checks exactly what applies to your site and navigates the approvals process for you, so you don’t have to.
Pricing and build times
Granny flats are a cost-effective way to add a whole new dwelling to your property, with designs that can be tailored to suit your budget, site and lifestyle. Pricing generally starts from around $100,000, depending on the size, layout, inclusions, approvals, location and site access.
Once your design is approved, a granny flat can be constructed in as little as 18 weeks, with many assembled to lockup in just 3 to 6 days.
We work with clients across South East Queensland and Northern New South Wales. Because pricing, delivery and lead times can vary depending on your design, location and site access, the best next step is to get in touch so we can confirm exactly what’s possible for your property.
