A 70m² Addition Designed for Growing Families
Based on our 70m² Second Storey Addition Package we added:
- Three bedrooms
- One additional living room
- One family bathroom
- Approximately 70m² of additional floor space
This second storey addition in Marayong, Western Sydney, created valuable additional living space by extending upwards rather than outwards.
With three bedrooms, a family bathroom and a separate living area, the new upper level provides a practical solution for a growing family needing more room without reducing their existing backyard space.

Planning and Design of the Marayong Addition
The Marayong project demonstrates how approximately 70m² of additional floor space can significantly improve the functionality of an existing home.
The new upper level incorporates three bedrooms, a family bathroom and a separate living room, providing dedicated spaces for sleeping, relaxing and everyday family activities.
By adding another level to the existing dwelling, the design increases the home’s usable living area while retaining its original ground-floor footprint.
This approach is particularly beneficial for homeowners who want more internal space without compromising their outdoor areas.
The Completed Marayong Second Storey Addition
The completed second storey addition provides an additional living zone, offering greater flexibility for family members to enjoy their own space.
With three bedrooms and a separate living room upstairs, the home benefits from improved separation between sleeping areas and shared family spaces.
The project showcases how a thoughtfully planned second storey addition can transform an existing home into a more spacious and functional family residence.
For homeowners considering a second storey addition in Marayong or surrounding Western Sydney suburbs, this project provides an example of the additional space achievable with our 70m² package.
