House Extensions on the Central Coast

Expand Your Space

Create the additional space your home needs with a well-designed extension, whether it’s a single-storey addition or a full second level.

At Designer Building, we ensure every site is kept immaculate and properly protected, particularly in well-established neighbourhoods, maintaining both your privacy and the appearance of the surrounding streetscape. We also manage all essential preliminary requirements, including soil reports, structural engineering, surveying and planning, to ensure a smooth and efficient process.

We specialise in delivering high-quality extensions that integrate seamlessly with your existing home. Based on the Central Coast, we proudly work with clients across Lake Macquarie, Erina, Wyong, Budgewoi and surrounding areas.

Whether you’re adding a ground-floor extension, building a second storey or creating a custom layout, our team handles every detail from start to finish. We take pride in maintaining a clean, organised and respectful worksite, minimising disruption to your household and neighbours.
