Granny Flats Vs Tiny Homes: What’s Right For Your Block?

by | Jul 1, 2025

In Victoria’s competitive housing market, smart homeowners and investors are looking beyond traditional options to maximise the value of their land. Two of the most talked-about solutions are granny flats and tiny homes, compact, self-contained dwellings that offer flexibility and a potential income stream.

But while they may appear similar at first glance, these options differ dramatically in terms of comfort, legality, long-term ROI, and suitability for Melbourne’s urban landscape.

So, how do you know which one is right for your block?

Let’s explore the key differences, break down the pros and cons, and explain why most Victorian homeowners are turning to granny flat builders Melbourne locals trust, like Innovista Group, to deliver lasting results.

Understanding The Basics: Granny Flats VS Tiny Homes

Before diving into the features and benefits, let’s define what each of these dwellings is.

Granny Flats

Granny flats, also known as secondary dwellings, are fixed, fully compliant, self-contained homes built on the same title as a primary residence. In Victoria, recent planning reforms have made it much easier to build these dwellings, especially in residential zones.

A typical granny flat includes:

  • 1-2 bedrooms
  • A full bathroom
  • Kitchen and laundry
  • Living area
  • Separate access from the main home

They’re built on permanent foundations, connected to services, and legally recognised as real dwellings.

Tiny Homes

Tiny homes are often built on wheels or trailers and are typically mobile. They appeal to minimalists, off-grid enthusiasts, and those looking for temporary or flexible accommodation. In most councils, however, they are not considered dwellings; they are viewed more like caravans or movable shelters.

Most tiny homes include:

  • Compact living and sleeping space
  • Minimal storage
  • Composting toilet or limited plumbing
  • Often require solar or tank systems

Tiny homes can be fun, quirky, and eco-conscious, but they come with serious limitations in urban areas.

Granny Flat

1. Legal Compliance In Victoria

When it comes to legality and council support, granny flats win hands down.

Granny Flats

  • Recognised as permanent dwellings under the Building Code of Australia (BCA)
  • Compliant with local planning rules under Victoria’s Small Second Dwellings (SSD) reforms
  • Add to your property valuation

Tiny Homes

  • Often unregulated and not compliant with building codes
  • Usually treated as caravans, not dwellings
  • Can be removed at any time and don’t count towards your property’s value

If you’re considering long-term value and rental potential, working with licensed granny flat builders Melbourne authorities trust ensures you’re building legally and safely.

2. Comfort And Functionality

Let’s face it, comfort matters, especially if you or your family are living in the space full-time.

Granny Flats

Offer full-sized rooms, regular appliances, and conventional plumbing. You can expect:

  • Separate bedrooms
  • Full kitchens with ovens, cooktops, and rangehoods
  • Standard plumbing and bathrooms
  • Heating/cooling systems
  • Adequate storage and lounge areas

They feel like a real home, because they are.

Tiny Homes

Often require compromises:

  • Loft beds accessed by ladders
  • Fold-away tables and compact bathrooms
  • Limited storage
  • RV-style utilities

While charming and space-efficient, they’re rarely ideal for families, elderly relatives, or long-term tenants.

3. Investment & Resale Value

From a financial standpoint, granny flats offer a clear edge.

A well-designed granny flat can add $100,000+ in capital value and generate up to $550 per week in rental income, all while staying on a single land title.

Tiny homes, by contrast, are often seen as personal property. Because they’re not fixed to land, they don’t increase the value of your property and may actually raise questions from lenders or buyers.

For investors, this makes granny flats the smarter and safer choice. If you’re considering high-yield secondary dwellings, custom granny flats Melbourne specialists like Innovista can tailor the design to your financial goals.

4. Utility Connections And Approvals

Granny flats are built like traditional homes, which means:

  • Permanent connections to electricity, water, and sewer
  • Clear paths for permits and inspections
  • Easier property management for owners or landlords

Tiny homes often rely on:

  • Water tanks and composting toilets
  • Solar or battery systems
  • Greywater setups

While great for rural or off-grid living, these setups can become problematic in suburban environments where tenants expect modern services.

5. Flexibility In Design And Layout

With custom granny flats Melbourne builders like Innovista, you’re not stuck with a one-size-fits-all floorplan. You can:

  • Choose from 1-bedroom or 2-bedroom layouts
  • Select between Signature or Luxe finish levels
  • Add decks, alfresco, or accessibility features
  • Optimize orientation for light and airflow

Tiny homes are limited by transport regulations. They generally max out at 25–30m², which limits design freedom significantly.

Granny flats can be as large as 60m² (or more, depending on zoning), offering real liveability and better long-term usability.

6. Size Matters, Especially For Families And Tenants

Granny flats provide genuine living space. A Lana 60, for instance, offers:

  • Separate bedrooms
  • Open-plan kitchen and living
  • Private bathroom and laundry

Perfect for:

  • Ageing parents
  • Grown-up children
  • Long-term tenants
  • Guest accommodation

Tiny homes, in contrast, may be suitable only for solo occupants or short stays due to their limited size.

7. Comparing The Price

Tiny homes are often marketed as affordable, with entry-level models starting around $100,000. But high-spec tiny homes can exceed $250,000, especially when factoring in delivery, setup, and off-grid systems.

Granny flats, on the other hand, start around $140,000, with more luxurious models like Innovista’s Lana 60 Luxe reaching $240,000-$300,000.

The difference? Granny flats are:

  • Legally compliant
  • Value-adding
  • Rent-ready
  • More spacious and practical

In other words, you’re not just spending, you’re investing.
