2 Bedroom Granny Flat Designs: Layouts That Work for Melbourne Families

Table of Contents

Last updated October 2026

The right 2 bedroom granny flat designs make a 60m² home feel calm, private and easy to live in, whether it is for a parent, an adult child or a tenant. The layout matters as much as the floor area. This guide walks through the five G-Flat™ two bedroom layouts, the design principles behind them, how to match a plan to your block shape, and what each finish level costs.

Key takeaways

  • Every G-Flat™ is a 60m², two bedroom turnkey build with five floor plans to choose from.
  • Stella suits corner and irregular blocks, Aurora suits narrow lots, Lana fits most backyards, Lana 2 adds a second bathroom and Sirius has large 4 x 3m bedrooms.
  • Block shape, access and orientation usually decide which layout works for you.
  • All five plans cost the same within a finish level, from $198,000 to $265,000 turnkey.
  • A free site assessment confirms which layout fits your block and the price for your site.

Why two bedrooms work so well

A second bedroom turns a compact home into a flexible one. It can be a bedroom for a carer or grandchild, a home office, a guest room or a hobby space. That flexibility means the home can change use over the years without any building work.

Two bedrooms also suit the people who often live in a granny flat:

  • Ageing parents: one bedroom to sleep in and a second for visitors or overnight help.
  • Adult children: room for a desk or flatmate while they save.
  • Tenants: couples, sharers and people who work from home.
  • Downsizers: a smaller home with space for family to stay.

In Victoria, a granny flat of 60m² or less on the same lot as an existing home is a small second dwelling. It needs its own kitchen, bathroom and toilet, which every two bedroom G-Flat™ plan includes. The Victorian Government small second dwellings page explains the full rules.

Design principles behind good 2 bedroom granny flat designs

Good layouts share a handful of principles, whatever the shape of the home.

Separate living and sleeping

Bedrooms work better when they are set away from the kitchen and living area. That keeps noise down and gives each person some privacy, which matters when two adults share.

Keep circulation short

Every metre of hallway is a metre taken from a living space. Strong 2 bedroom granny flat designs keep corridors short so more of the 60m² goes into rooms you actually use.

Plan the kitchen as the hub

An open kitchen that looks into the living area makes the whole home feel larger. Our guide to kitchen design for granny flats covers compact layouts in detail.

Build in storage

Built-in robes, a linen cupboard and a laundry with cabinetry keep clutter out of living areas. Storage planned at design stage is far easier than adding furniture later.

Bring in light and air

Windows on more than one side, glazed doors to a deck and skylights in some finish levels help a small home feel open. North-facing living areas also help with comfort through Melbourne winters.

Think about privacy from the main house

Entry position, window placement and decking all affect how private the granny flat feels for both households. Our guide on how to design a granny flat that feels like a full-size home has more ideas.

The five G-Flat™ 2 bedroom granny flat designs

All five plans are 60m² with two bedrooms, a kitchen, a living area and a bathroom. The difference is how that space is arranged.

Floor planShapeSuitsStandout feature
StellaL-shapedCorner and irregular blocksTurns a corner to follow two boundaries
AuroraLong and narrowTight and side-access blocksWalk-in robe in bedroom one
LanaBalanced rectangleMost backyardsEasy to position and furnish
Lana 2Balanced rectangleShared livingSecond bathroom
SiriusSquareWider, squarer backyardsLarge 4 x 3m bedrooms and L-shaped kitchen

Stella: the L-shaped plan

Stella’s L shape lets the home turn a corner, so it can follow two boundaries or frame an outdoor area. That makes it a natural fit for corner blocks and irregular lots where a straight rectangle would leave awkward leftover space. Our guide to building a granny flat on a corner block explains how it works in practice.

Aurora: long and narrow

Aurora stretches the floor plan along its length, so it can sit down the side or back of a tight block. Bedroom one includes a walk-in robe, which gives the main bedroom a more generous feel. It suits narrow lots and blocks where the main access is a side path.

Lana: the balanced all-rounder

Lana is a balanced rectangle that fits most standard backyards. The proportions make it easy to position, easy to furnish and easy to live in. Our display G-Flat™ in Ferntree Gully is a furnished Lana, so you can walk through it in person.

Lana 2: two bathrooms

Lana 2 builds on the balanced Lana layout and adds a second bathroom. That suits two adults sharing, such as housemates, an adult child and a partner, or a parent with a live-in carer. Each person gets their own bathroom without giving up a bedroom.

Sirius: square with big bedrooms

Sirius uses a squarer footprint to give both bedrooms a generous 4 x 3m size. The L-shaped kitchen adds bench space and keeps the cook out of the walkway. It works well on wider backyards where depth is not an issue.

Choosing 2 bedroom granny flat designs by block shape

Your block usually narrows the choice quickly.

  • Corner or irregular block: start with Stella.
  • Narrow block or limited side access: start with Aurora.
  • Standard rectangular backyard: Lana or Lana 2.
  • Wide, square backyard: Sirius.

Then check the details that can shift the decision:

Matching a layout to the people living in it

The same block can suit more than one plan, so think about daily life too:

  • A parent who wants a guest room may prefer Lana or Sirius.
  • Two adults sharing may prefer Lana 2 for the second bathroom.
  • Someone who values a large main bedroom with a walk-in robe may prefer Aurora.
  • A household that wants a sheltered outdoor area may prefer Stella, whose L shape can frame a courtyard or deck.

Layout mistakes to avoid

A few common choices can make a small home harder to live in:

  • Bedrooms off the living room: doors opening straight into the lounge reduce privacy and make the home feel smaller.
  • Long corridors: they use floor area without adding living space.
  • Too little bench space: a compact kitchen still needs room to prepare meals and store appliances.
  • Ignoring the outlook: windows facing a fence or the main house’s living room make both homes feel less private.
  • Forgetting outdoor space: a deck or landing at the entry gives residents somewhere to sit outside.
  • Choosing a plan before checking the block: setbacks and easements can rule out a layout, so have the site assessed first.

Finish levels and prices

Every plan comes in four finish levels, and all five plans cost the same within each level.

Finish levelTurnkey priceHighlights
Affordable$198,000Steel stumps, skillion roof, 2.7m ceilings, 20mm stone, Haier appliances
Homestead$208,000Adds concrete waffle slab, pitched concrete tile roof, Hebel facade, R2.5 wall insulation
Signature$238,000Adds 40mm stone, 20m² decking, bathroom skylight, Electrolux appliances
Luxe$265,000Adds 3m ceilings, kitchen and bathroom skylights, curved island, underfloor heating

Prices are a guide only and depend on your site. Sites 70km or more from the Melbourne CBD attract a 12.5% regional surcharge. A free site assessment confirms the price for your block.

Every G-Flat™ also includes the building permit and all required reports, all plans, connection of services up to 10m from the main house, stone benchtops, soft-close cabinetry, SPC hybrid flooring, double-glazed windows, a reverse cycle split system and a 10-year structural warranty. See our granny flat inclusions guide, Luxe vs Signature and granny flat pricing in Victoria for more detail.

How long it takes

A G-Flat™ takes approximately 5 months end to end, from planning through to handover, including the building permit, construction and connection of services. Settling on your floor plan and finish level early helps keep the design and permit stages moving smoothly.
