3 Things to Know Before Adding a Granny Flat

1. Council Approval & Regulations Matter

Granny flats (secondary dwellings) in NSW are subject to specific zoning and approval rules. At Velliss Building, we help clients determine whether their land meets the criteria for a Complying Development Certificate (CDC) or if a Development Application (DA) is required. Getting the right advice early can save you significant time and money. Key factors include your lot size, setbacks, existing structures on the property, and local council requirements. We navigate this process with you from the very beginning so there are no surprises down the track.

2. Budget for the Full Picture

While many people budget for construction only, don't forget costs like excavation, service connections (water, sewer, electricity), finishes, and landscaping. We work closely with clients to provide a clear, itemised quote so there are no surprises later. Our experience in delivering complete building solutions โ€” from concept to completion โ€” means you can rely on us for the entire process. A realistic budget upfront leads to a much smoother project overall.

3. Design for Comfort, Style, and Functionality

A granny flat should feel like a well-designed home, not just an add-on. At Velliss Building, we focus on creating modern, comfortable spaces that suit your lifestyle. From smart floorplans to quality kitchens, bathrooms, and energy-efficient finishes, we tailor every detail. Whether it's for family, guests, or rental income, thoughtful design makes all the difference. We'll work with you to maximise the available space while ensuring the finished result complements your existing home and adds real long-term value to your property.

Stay connected โ€” if you'd like to talk more, have a question, or are ready to bring your next project to life, we're just a message away.
