100% Satisfaction Guaranteed

Have you outgrown your existing home, and are you faced with two options; should you move to a bigger home or make your current home bigger? If you don’t want the expense and effort of moving, then a house extension or addition might be what you are looking for.

Benefits of a ProfessionalHome Extensions & Additions Service

Home extension and addition means you can extend your home, whether at the ground floor level or by adding another level upwards. You can also do both – extending both up and out.

Regarding extensions and additions, we recommend you engage a qualified professional builder. Too often, we have seen evidence of when a homeowner decides to ‘do it themselves, and the work is either never finished, or the work is completed to a less than professional standard that can sometimes lead to more problems. This can include missed inspections from certifying authorities (councils and building certifiers), meaning the building works may be unsafe. This can then lead to more problems when the owner tries to sell the house.

We do home extensions in Wollongong-wide and pride ourselves on delivering high-quality building projects completed and certified to all relevant standards.
