When planning your granny flat, one of the biggest decisions you’ll make is how many bedrooms to include. A 1-bedroom design is affordable and compact, while a 2-bedroom granny flat provides more flexibility—ideal for growing families, guests, or rental income.
In this guide, we’ll help you weigh up the pros and cons of both options so you can choose the right fit for your block, lifestyle, and long-term goals.
Why Bedroom Count Matters
The number of bedrooms you choose impacts:
- Overall size and layout
- Construction and approval costs
- Rental or resale value
- Practicality for your family or tenants
Choosing the right option means balancing your immediate needs with potential future uses.
Why Choose a 1-Bedroom Granny Flat?
Best suited for: Singles, couples, retirees, or studio-style rentals
Key benefits:
- Lower cost – Fewer materials and faster build time
- Easier approvals – Often simpler to meet council and CDC rules
- Compact footprint – Great for smaller or sloped blocks
- Low maintenance – Ideal for minimal upkeep and furnishing
Things to consider:
- Limited appeal for families or shared rentals
- Smaller rental return
- May not maximise long-term resale value
Why a 2-Bedroom Granny Flat Might Be Better
Best suited for: Families, tenants, home offices, or future flexibility
Key benefits:
- More usable space – Perfect for dual living, work-from-home setups, or guests
- Greater rental income – Higher weekly rent potential
- Better resale appeal – More versatile, marketable layout
- Adaptability – Grows with your changing lifestyle
Things to consider:
- Requires a slightly larger block
- Higher build costs—but often better return on investment
- May need additional planning for access, privacy, and orientation
What to Consider Before Deciding
- Block size & layout – Can your land comfortably fit a 2-bedroom while meeting CDC/DCP requirements?
- Purpose – Is it for family, tenants, or personal use? Will that change in future?
- Budget – A 1-bedroom saves upfront, but a 2-bedroom may deliver better long-term value
- Approval path – 1-bedrooms are often easier to approve, but many 2-bed designs still meet SEPP guidelines
- Privacy & access – Will the flat sit close to the main home? Plan bedrooms and entries with separation in mind
Expert Tip
If you’re unsure, a well-designed 2-bedroom granny flat is often the most versatile option. With thoughtful planning, it doesn’t always require more land—and it offers more value whether you’re living in it, renting it out, or planning ahead.
