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.

01

Test feasibility

We review height, floor space, setbacks, heritage or other constraints and early structural considerations.

02

Plan the stair and structure

A successful addition protects useful ground-floor space while creating a practical structural and circulation strategy.

03

Respond to neighbours

Privacy, overshadowing, views and streetscape are addressed early to reduce avoidable approval risk.

04

Coordinate the documentation

Design, BASIX, engineering and approval information are brought together into a consistent package.

Typical scope

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.
