As land availability and prices continue to rise, it’s little wonder savvy investors are turning towards granny flats as a relatively low cost, high return property investment.
With facades designed to complement your existing property, our Granny Flat Collection can add to the resale value of your home and give you a healthy second income which you can use to help pay off your mortgage.
Whether you’re looking for more space to accommodate family members and visitors, a private home office away from the main residence or an attractive rental opportunity for tenants, we have a design to suit.
As an Australian family owned company, we’ve built a reputation for over 30 years for building high value, high quality family homes. We understand that every family is different, which is why each of the homes we build are unique.
Our commitment to excellence ensures that your home building experience is as seamless and smooth as possible, giving you the opportunity to live a lifestyle beyond what you imagined possible.
