Home renovations

Whether you want to add new touches to your kitchen, rearrange your living and bedroom allocations and spaces, or incorporate bespoke architectural designs for your entire home, we work intricately on interior details and deliver unmatched finishes.

2nd storey extensions

Adding a second storey can be the best way to accommodate growing families, especially where blocks are small. Olix has the experience with semi-detached and terrace houses to ensure your second storey extension is built with consideration and care of your neighbour’s property.

Bathroom renovation

We offer end-to-end bathroom renovation solutions. We can transform your old bathroom into a stylish bathroom with contemporary finishing and the latest fixtures. We assure timely project completion, with no surprises on the budget.

Studios and granny flats

If you need extra space for family, visitors, or your weekend hobby, think about adding a studio to your property. Olix has experience in building for accessibility and has constructed age care and disability compliance spaces.
