Banksia 2 Bedroom customised for Accessibility

Following a health scare, my wife and I were facing separation, she in a nursing home and me in a tiny retirement unit at an eye-watering cost. 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.
