Perth’s growing demand for smarter housing solutions has made multi-dwelling developments an increasingly popular choice for homeowners and investors. Two of the most common approaches are house behind house developments and side-by-side developments. Both offer unique opportunities—but deciding which is right for you depends on your block, lifestyle, and long-term goals.
As a trusted building company in Perth, SMG Construction has guided many clients through this decision. Below, we’ll break down the pros and cons of house behind house vs. side by side development so you can make the best choice for your property.
What is a House Behind House Development?
A house behind house development involves building a second dwelling at the rear of an existing or newly created lot. This design maximises depth and often provides privacy, as the homes are separated by driveways and landscaping.
Pros:
- Great for deep blocks.
- Provides privacy for each household.
- Can retain existing front dwelling (ideal for investment).
- Often more affordable than full subdivision.
Cons:
- Longer driveways may reduce outdoor space.
- Rear home may have less street frontage and natural light.
- Can feel less accessible compared to street-facing designs.
What is a Side-by-Side Development?
A side by side development places two dwellings next to each other, typically with separate driveways and street-facing entries. This approach works best for wider blocks and delivers a modern, symmetrical look.
Pros:
- Both homes enjoy street frontage.
- Equal access to light, space, and amenities.
- Highly attractive for resale value.
- Sleek, contemporary aesthetic.
Cons:
- Requires a wide block (not always available).
- Building costs can be higher.
- Less privacy between dwellings compared to rear lot options.
Key Considerations: Which Option is Best for You?
When deciding between house behind house vs. side by side development, consider:
- Block shape and size: Is it deep or wide?
- Lifestyle needs: Do you prefer privacy or open frontage?
- Budget: What works best for your financial plan?
- Investment goals: Which option has stronger appeal in your target market?
