Expanding Both Floors for Maximum Space
If your home is already a two-storey house, our expert builders can extend both the ground and upper levels, seamlessly integrating the new space with your existing structure.
This allows for:

By extending both storeys, you’re maximising every inch of your property without compromising your outdoor space, making it an excellent long-term investment.

New Outdoor spaces (Back & Front Yard Extensions)
Your outdoor space is just as important as the interior of your home, offering areas for relaxation, entertaining, and play. In addition to increasing the internal space of your home through different extensions, we are also able to help extend outdoor spaces.
This can involve revising your floor plan and make the required changes and additions to increase the size of both your front and back yards to meet the needs of your growing family. Whether your family needs more room to play, entertain guests, or simply enjoy the outdoors, our team ensures that every available space is optimised for both beauty and practicality.
Tailored Solutions for Every Lifestyle
We understand that every household is different—some families need expansive outdoor areas for children to run around and play, while others prefer low-maintenance courtyards or stylish alfresco dining areas. Whatever your vision, we can help design and build custom outdoor extensions that enhance your lifestyle and increase the value of your home.
