Lake Macquarie City Council has taken steps to encourage more diverse housing options through amendments to its planning framework. One of the key provisions enabling this is Clause 4.1A of the Lake Macquarie Local Environmental Plan (LMLEP 2014). For landowners, developers, and planners, this clause presents a valuable opportunity, particularly in established residential zones.  

What is Clause 4.1A? 

Clause 4.1A functions as an exception to the minimum lot size requirements typically imposed under the LEP. While standard subdivision controls often require larger lots, or an exception to the minimise lot size as long as subdivision occurs after ‘lock-up stage’, Clause 4.1A of LMLEP 2014 now allows for the Torrens Title Subdivision of residential land without the need to construct an additional dwelling, or even having building plans approved for the site, enabling more flexible subdivision outcomes. 

In Lake Macquarie: - R2 Low Density Residential zone, vacant land can be subdivided into lots as small as 250m² - R3 Medium Density Residential zone, vacant land can be subdivided into lots as small as 200m² 

This represents a significant departure from traditional exception to the minimum lot size clauses seen in many Council LEP’s and opens the door to smaller lot configurations that are suited for more affordable housing typologies, like terrace housing or compact detached dwellings, which would generally otherwise be subdivided under a Strata Title Subdivision. This results in additional expense for the developer and future owners of the site.  

Demonstrating Developability – Building Envelope Plans  

While Clause 4.1A provides flexibility, it does not guarantee approval. A key requirement is demonstrating that the resulting lots are capable of supporting a future compliant development. This is where compliance with the Lake Macquarie Development Control Plan (LMDCP 2014) becomes critical, particularly Clause 3.19 – Building Envelope of Part 8 of LMDCP 2014.  

Clause 3.19 requires the submission of a building envelope plan where land is subdivided under Clause 4.1A. The purpose of this requirement is to ensure that each lot can realistically support a dwelling that meets the relevant planning controls. The building envelope plan must provide sufficient detail to demonstrate developability, including elements such as the proposed building footprint and any ancillary structures, required setbacks, site coverage calculations, landscaped area provisions, driveway and parking arrangements, private open space dimensions, and the identification of any site constraints such as asset protection zones or flood restrictions. In some cases, shadow diagrams may also be required. Ultimately, Clause 4.1A works in conjunction with the DCP controls to enable smaller lot subdivision while ensuring that quality urban design outcomes are maintained, meaning that subdivision proposals must be supported by clear and well-considered Building Envelope Plan, which can be prepared by Parker Scanlon.
