A well-designed granny flat does more than maximise space — it enhances the way we live, work and unwind in smaller, smarter dwellings. At Pleysier Perkins Mini Homes, we focus on floor plans that are as efficient as they are elegant, grounded in architectural thinking and tailored to the realities of Australian sites.
How Big Is a Granny Flat, Really?
Most granny flats in Australia range from around 37m² to 74m² (roughly 400 to 800 square feet), depending on local council rules and block conditions. The challenge? Fitting all the essentials — living, dining, kitchen, bathroom and bedroom — into a compact footprint that still feels open and liveable.
Each of our models begins with a core layout, but every one is flexible. From The Popstar’s streamlined, rectangular plan to The Wedge’s clever use of angular geometry, we design with adaptability in mind.

What Architects Consider in Small-Space Design
Designing a small space means making every square metre work harder — without sacrificing beauty or comfort. Here are some of the key principles we use:
1. Open Plan Living
Removing internal walls between kitchen, living, and dining zones opens up the space and brings in more natural light. It also creates flexibility in how the space is used day to day.
2. Multi-Use Spaces
In smaller homes, every room needs to earn its keep. Think: a desk that doubles as a dining table, or a living zone that transforms into a guest area when needed.
3. Integrated Storage
Joinery is key — from under-bed drawers to floor-to-ceiling cabinetry, clever storage can keep your space tidy and feeling generous.
4. Natural Light and Ventilation
Orientation, window placement, and glazing size are carefully considered to enhance comfort and energy efficiency. Skylights and highlight windows can bring in light without compromising privacy.
5. Indoor–Outdoor Flow
Access to decks or courtyards can effectively ‘extend’ the living space, making small interiors feel larger and more connected to the landscape.
