Perth Rear Strata / House Behind House FAQs
What is a house behind house development?
A house behind house development (also known as a rear strata development or battle axe development) is a second, separate dwelling built behind an existing home. This development involves subdividing the original block into two separate lots, and creates two distinct properties, each with separate titles.
Does a house behind house project require a knockdown?
No – it’s possible to not make any changes to the existing home on the block when subdividing and developing the second house. However, some property owners make the most of the opportunity to subdivide and build two new homes after knocking down the existing dwelling. Progen Developments specialise in house behind house and knockdown rebuild projects in Perth.
What are the benefits of a house behind house development?
Rear strata developments enable property owners to maximise the property value of larger blocks by adding a second dwelling. While many sell one or both dwellings immediately, many choose to stay in their existing home and rent the second dwelling or use it to accommodate extended family. Along with increased property value, the benefits to working with a rear strata builder like Progen Developments to build a battle axe house include generating rental income, unlocking equity, and providing independent living for relatives.
Can a house behind a house be subdivided and sold separately?
Yes – however, there are a number of approvals involved, including subdivision approval and Building Approval. Working with a rear strata builder like Perth’s Progen Developments ensures you understand the feasibility of your project in terms of compliance and approvals before it gets underway.
How is vehicle access provided to the house at the rear?
The most common ways of providing vehicle access to a rear strata build is with a battle axe (this refers to the shape of the block) arrangement or a side driveway. Vehicle access is a key consideration when developing a house behind a house in Perth.
