When it comes to creating more space for your family, homeowners in Perth often face the same big question: should you build a granny flat or extend your home? Both options offer valuable benefits, but the right choice depends on your property, your lifestyle needs and your budget. At Classic WA, we specialise in designing and building modern granny flats in Perth that provide stylish and functional solutions for families. Here we explore the key differences between granny flats and home extensions to help you make the best decision.

What is a Granny Flat?

A granny flat is a self contained secondary dwelling built on the same block as your main home. It can be used to house elderly parents, give independence to teenagers or young adults, or even generate rental income. Designs range from compact one bedroom units through to spacious three bedroom layouts, giving families flexibility to choose what works best.

What is a Home Extension?

A home extension involves expanding your existing house by adding new rooms or extending living areas. This can be a ground floor build, a second storey addition or even a large renovation. Extensions are usually integrated into the main home, which makes them a good option for families who want to keep all their living areas connected.

Comparing Costs

Granny flats are often more cost effective than home extensions because they are smaller, self contained units with straightforward construction requirements. Extensions can be more expensive due to structural changes, roofing adjustments and the need for building integration. If you are looking for a cost friendly way to add extra living space, a granny flat may be the smarter option.

Lifestyle and Privacy Benefits

One of the main advantages of a granny flat is privacy. For example, a two bedroom unit like the Troughton design provides separate living spaces while still being close to the main home. This makes it ideal for multi generational families or for those wanting rental income.

Extensions, on the other hand, create more space within the main home. If you want a bigger living room, an extra bathroom or a new bedroom attached directly to your property, then extending might be the better choice.

Property Value Considerations

Both options can increase the value of your property, but in different ways. Granny flats add the appeal of dual living and potential rental income, which is highly attractive in Perth’s rental market. Extensions typically add value by increasing the overall size and usability of the main residence.

Which is Right for You?

If you want flexibility, independence and potential rental income, a granny flat is a strong choice. If your goal is to expand the size of your main home, then an extension might suit better. Classic WA offers a wide range of designs, from Gran’s Cottage for singles to the Eco Micro Home for families, so you can find the right fit for your lifestyle.

Conclusion

Both granny flats and home extensions have their benefits, but if you are seeking privacy, affordability and long term flexibility, a granny flat is hard to beat. Classic WA’s expert team can help you design the perfect solution for your property, whether it is a compact one bedroom retreat or a larger family dwelling.
