Popular reasons homeowners choose affordable extensions include:

  • Creating a larger kitchen diner
  • Adding a utility room
  • Building a home office
  • Expanding family living space
  • Increasing property value
  • Avoiding the cost of moving home

Use Existing Services

Keeping kitchens, drainage, and plumbing near existing locations can reduce labour costs.

We help clients select durable materials that offer excellent appearance without premium price tags.

Plan Properly From Day One

Mistakes and late changes cost money. Good planning saves thousands.

Josh and his team have worked on several projects at our house, not least a new flat roof and large lantern. The boys were very friendly and polite - and importantly neat and tidy! Costings were very reasonable and work was carried out on time. It was also great that Josh was always available for a chat - unlike some contractors we have used in the past.

Absolutely thrilled with the work completed by Primary Construction on our 2-storey extension! From start to finish, the team was professional, reliable, and highly skilled. They built a beautiful space for us, complete with stunning bifold doors and a modern kitchen that perfectly blends with our home's style. The attention to detail was outstanding, and the quality of craftsmanship exceeded our expectations. They also kept the site tidy and adhered to timelines, which made the entire process smooth and stress-free. Highly recommend Primary Construction for any building project!

Right from the outset Josh was warm, friendly and reassuring. His project planning was timely and professional. The build quality and detail of his work of the interior improvements were first class from beginning to the end. His team were always friendly and polite and very clean and tidy.
