Add space without losing the backyard
Second Storey Additions Sydney
Upper-floor additions need more than a floor plan. We coordinate streetscape, setbacks, privacy, shadow, structure, stairs, existing roof conditions and the right approval strategy.
Discuss your project →Test feasibility
We review height, floor space, setbacks, heritage or other constraints and early structural considerations.
Plan the stair and structure
A successful addition protects useful ground-floor space while creating a practical structural and circulation strategy.
Respond to neighbours
Privacy, overshadowing, views and streetscape are addressed early to reduce avoidable approval risk.

FAQ
Common questions
Is a second storey possible under CDC?+
It may be, but every relevant development standard must be satisfied. Otherwise a DA may be more appropriate.
Will the existing house need strengthening?+
That requires assessment by a structural engineer. Early coordination helps the design respond to likely structural work.
