💰 Budgeting & Granny Flat Costs
Let’s talk turkey—and by turkey, we mean how much it costs to add serious value to your backyard. The cost of building a granny flat can vary depending on your block’s slope, soil condition, access, preferred layout, and level of finish. But don’t worry—we don’t do vague ballparks. Here’s a realistic starting point:
- Studio Granny Flat – From $95,000+
- 1-Bedroom Granny Flat – From $115,000+
- 2-Bedroom Granny Flat – From $135,000+
And yes, that’s for a turnkey build, you get the keys, and it’s move-in ready. No half-finished shell or surprise add-ons down the track.
What’s Included in Our All-Inclusive Quotes?
When we say all-inclusive, we mean everything you need to get your granny flat built, finished, and functioning. Here’s what we cover:
🏗️ Site Preparation
We start from the ground up, literally. Site prep includes clearing vegetation, minor demolition (if needed), levelling the land, and ensuring access for equipment and trades. We also manage any necessary soil testing and foundational adjustments (like piering or slab preparation) to ensure a stable, durable build. It’s not the glamorous part of the process, but it’s critical for long-term structural integrity.
🔧 Appliances and Fixtures
Yep, our pricing includes essential kitchen and laundry appliances so you’re not left cooking on a camping stove. Typically included:
- Oven and cooktop combo
- Rangehood
- Laundry tub
- Bathroom fixtures (vanity, shower, toilet, etc.)
- Sink and mixer taps
We use known, reliable brands, and if you want to upgrade, we’ll work that into your design and quote. No stress.
🧱 Materials and Labour
From the timber in the frame to the roof tiles, cladding, insulation, and everything in between, our quotes include high-quality materials sourced from trusted Australian suppliers. Labour covers all skilled trades needed: carpenters, concreters, roofers, and everyone who helps get your granny flat from plan to completion. No shortcuts. No shoddy finishes. Just honest work and durable materials that hold up to Aussie weather.
💧 Waterproofing
This is the part that makes bathrooms and laundries future-proof, literally. We follow strict Australian Building Codes to ensure every wet area is professionally waterproofed. Showers, walls, floors, and corners get the treatment so you don’t end up with water sneaking into places it shouldn’t. It’s not just about compliance, it’s about protecting your investment for the long haul
🎨 Interior Finishes
AWe believe small spaces deserve big style. That means:
- Premium vinyl, laminate or tile flooring
- Freshly painted walls and ceilings
- Skirting boards, cornices, and door hardware
- Built-in robes (if you want ‘em)
- Designer lighting and electrical switchgear
Every detail is selected with functionality and flow in mind, so the space feels bigger and brighter than it is.
🚿 Plumbing and Electrical
We handle every connection and installation, from water lines and drainage to wiring, power points, and lighting. That includes:
- Connection to existing sewer and water systems
- Hot water system installation (usually electric or gas)
- Smart meter or sub-meter installation
- Lighting fixtures, ceiling fans, smoke alarms, and exhausts
- NBN readiness (if you want it wired in)
Everything is done by licensed professionals and tested for safety and compliance before handover.
TL;DR: You’re Covered.
When we say “all-inclusive”, we mean it. You won’t be chasing down electricians or trying to figure out why your shower doesn’t drain properly. From clearing the block to turning on the lights, Premier Homes Victoria handles it all, professionally, transparently, and with your budget in mind.
