A growing family does not always mean you need to move

- Keep your school zone

More than extra rooms
More than extra rooms
A second storey can create additional bedrooms, a private parents’ retreat, beautiful bathrooms, children’s living areas or somewhere to work and unwind. But it is not simply about adding rooms. We consider how the whole home will work together, creating better flow, privacy, natural light and functionality for everyday life.
- Additional bedrooms
- A private parents’ retreat
- Beautiful bathrooms
- Children’s living areas
Old and new
Designed to feel like it belongs
A well designed second storey addition should feel like a natural part and continuation of the home, not something added as an afterthought. We carefully consider rooflines, proportions, materials, windows, stair placement and the relationship between the existing ground floor and new upper level. Inside, the layout is planned around how your family moves.
- Rooflines and proportions
- Materials and windows
- Stair placement
- Connection between levels

Questions
Second Storey Addition FAQs
Can I add a second storey to my existing home? +
Many homes can accommodate a second storey, but the existing structure, foundations, planning controls and proposed design need to be assessed first. Our team coordinates the relevant design and engineering advice during the early stages of the project.
Do I need council approval for a second storey addition? +
Second storey additions generally require formal planning and building approval. The pathway depends on your property and design. We manage the relevant drawings, consultants, documentation and approvals as part of our design and build process.
Will the new addition match my existing home? +
Yes. The new upper level is designed in response to the architecture and proportions of your existing home. Depending on your goals, that may mean closely matching the current style or thoughtfully updating the overall appearance of the house so old and new feel cohesive.
Can I live in the home during construction? +
That depends on the construction method and the extent of work to the existing roof and interiors. In some projects it may be practical to remain in the home for part of the build; in others, temporary relocation may be more comfortable. We discuss this with you during planning so you can prepare appropriately.
How much does a second storey addition cost? +
Cost depends on the size and complexity of the addition, structural requirements, site access, materials and finishes. Budget is considered as the design and scope develop, allowing priorities to be refined before detailed documentation is complete. We then prepare an estimate based on your actual project.
How long does a second storey addition take? +
Timing varies according to design, approvals and construction complexity. We establish a project programme once the scope is developed, giving you a clear understanding of the expected stages before building begins.
