It's the perfect time to build your Granny Flat, protect your family and build property wealth.

There are many reasons building a Granny Flat is a great idea. And whether it's to accomodate a growing family, create a space as an alternative to aged-care or to improve the value of your current property, now is the perfect time to speak to a Cubitt's consultant.

Early completion ahead of the contracted date saw us have the house tenanted quickly. Took a load of stress away and the finish is fantastic.

All of the staff, through administration, planning and building to completion, at Cubitt's have been most helpful and responsive in moving forward on the construction of a great little granny flat that gives great and appropriate extension to our Federation Cottage.

We chose Ian Cubitt’s to build a granny flat, with suitable modifications to meet the needs of our medical issues. Our granny flat has ramps, wide doorways, plenty of room to manoeuvre a wheelchair, sliding doors and a specially adapted bathroom. We could not be more delighted with the finished home. From pre-planning to completion we have been kept informed of progress. The site was always tidy, the tradespeople professional and polite, as were the supervising staff. The neighbours were very impressed with the low noise levels and lack of disruption to them.

We chose Cubitt’s as they had 3 flats of different designs in their showroom, which we could inspect. They organized Council approval for us as our granny flat had to be built close to our neighbour’s fences. Work was performed very efficiently. We even had some work done on a few Saturdays. The work was completed on time. We have no hesitation in recommending Cubitt’s.

The granny flat is nearing completion nearly a month ahead of schedule, with little to no problems, with all carpenters and trades being respectful and professional with their level of work being flawless.

Garden Studio Indoor

The Crawford - Our Garden Studio, back by popular demand

What could be more luxurious than owning a pool house or private guesthouse? Imagine waking up to pool views, or surrounded by your favourite corner of the garden. You could invite a few friends over for sunset cocktails by the pool, finally have space for that snooker table, or relax with a good book in a private retreat in the shade, cooled by a ceiling fan accompanied only by views of the lush Australian countryside.

The luxury lifestyle offered by the pool house is indeed an enviable one. What was once traditionally reserved for the ritzy upper-class, pool houses are no longer just for expansive estates. Pool ownership is on the rise in Australia, and the endless possibilities offered by a thoughtfully-designed pool house has led it to become an attractive addition for many Australians.

Have you ever considered a Granny Flat or studio as a pool house or guesthouse? Back by popular demand, Cubitt’s are relaunching The Crawford Garden Studio model. This multi-purpose studio is perfect for hosting a party as an open-air entertaining venue, or as a guesthouse, flexible Airbnb accommodation and more.
