The cost of building a granny flat in Blacktown depends on the size, design, finishes, site conditions and any additional works required. Picasso Homes can assess your property and requirements before providing a detailed quote based on your proposed granny flat.
Potentially, but it depends on your property's zoning, lot size, existing dwelling and other planning constraints. In NSW, secondary dwellings can be permitted in residential zones and may qualify for complying development where the relevant requirements are met. Blacktown City Council recommends checking the planning restrictions that apply to your particular property.
Your granny flat will require the appropriate approval pathway. Some Blacktown properties may qualify for a Complying Development Certificate rather than a full Development Application, provided the proposal meets the applicable NSW development standards. If it doesn't meet those requirements, a DA may be required.
For a secondary dwelling to qualify as complying development under the NSW Housing SEPP, one requirement is a minimum lot area of 450m². Other development standards and property constraints also apply, so eligibility should be checked for the individual site.
Yes. We can plan the granny flat around your available space, existing home, access requirements and how you want to use the new dwelling, creating a practical design suited to your property.
Timelines vary depending on the design, approval pathway, site conditions, selections and complexity of the build. Once we understand your project, we can provide a clearer indication of the expected design, approval and construction timeframe.
Yes. Under NSW planning rules, a secondary dwelling can be located within, attached to or separate from the principal dwelling, provided the proposal satisfies the applicable requirements.
We provide a complete granny flat building service covering design, planning, approvals and construction. Our focus is on creating a quality, functional granny flat suited to your property, budget and long-term plans.
