Granny Flats & Secondary Dwellings Sydney
A second home on the property needs to work for the people using it and alongside the main house.

Granny Flat or Secondary Dwelling
A granny flat or secondary dwelling affects more than the unused part of the yard. Access, privacy, services, outdoor space and the relationship with the main home all matter.
Tell us who the dwelling is for, how it will be used and what plans or advice you already have. We can discuss the proposed building work and what information is needed before pricing.
