KA Aged Care

“When renovating the bathroom and toilet for an elderly family member, safety and ease of use were our top priorities, and the result exceeded our expectations. From the initial consultation, the team carefully considered the senior’s mobility, daily routines, and practical needs, offering thoughtful and realistic recommendations that gave us great confidence. Throughout the renovation, noise and dust were kept to a minimum, and the site was cleaned thoroughly every day, which made the process much less disruptive. After completion, they kindly explained how to use the new fittings, helping our family member feel comfortable and confident. Now, the bathroom and toilet can be used independently and safely, giving our whole family peace of mind. We would sincerely recommend their services to anyone considering an aged care bathroom renovation."

Cornerstone Built is a fully licensed and insured building company, operating in line with current NSW regulations and industry standards. Every project is completed with the right approvals, insurances and documentations, giving you peace-of-mind from day one.

From small renovations and extensions to full new builds and light commercial projects, we manage the entire process under one roof. No need to juggle multiple contractors as we provide architectural, engineering and construction services as we provide all-in-one construction experience.
