Extending Your Home: Insights from Halligan Construction
Brenton from Halligan Construction shares valuable insights on why homeowners in Swan Hill are choosing extensions over new builds, as well as what’s involved in a successful home extension.
Why Choose an Extension Over a New Build?
For many Swan Hill homeowners, the decision to extend rather than move is driven by rising land costs and the desire to avoid relocation. Brenton points out that “you can stay in the home you love, without the disruption of moving.”
This approach preserves familiar surroundings and keeps the process more manageable compared to the time and cost of a new build.
Ensuring a Seamless Blend Between Old and New
A major focus for Halligan Construction is making sure extensions blend effortlessly with the existing structure. Brenton explains, “We pull the roof back on the original home and use custom trusses to connect old and new seamlessly.
Our goal is for it to look like it’s always been there.” This approach minimizes aesthetic and structural disconnect, helping extensions harmonize with the existing architecture.
Overcoming Challenges in Older Homes
Extensions, especially in older properties, often come with unique challenges. Halligan Construction has to “get creative” to meet building standards while aligning the new structure with the original layout.
Unexpected issues like settling or structural irregularities in older homes require custom solutions to ensure stability and cohesion.
Budgeting for Extensions: Hidden Costs
Brenton advises clients to consider several additional costs beyond the builder’s estimate. “Plans, permits, insurances, and engineering are just a few of the extra expenses clients may not expect,” he says.
Accounting for these costs early on can prevent surprises later in the project.
Maximizing Space and Functionality
Innovative design elements can make a significant difference in maximizing space. Halligan Construction recently used a raked ceiling to give an extension an open feel while minimizing cramped areas.
By incorporating features like raised ceilings, they create a sense of spaciousness even within limited square footage.
Navigating Local Building Codes
Complying with Swan Hill’s building regulations is essential, and Brenton notes that “each subdivision may have unique covenants.” By working closely with local drafters, Halligan Construction ensures that each project aligns with local codes from the design phase onward.
Incorporating Energy Efficiency
With the shift to a 7-star energy rating for new constructions, Halligan Construction prioritizes sustainable materials and energy-efficient designs. “Double glazing, full insulation, and suitable heating and cooling systems are essential to meet energy requirements,” Brenton explains.
These measures not only lower energy bills but also enhance the home’s value.
Timelines and Client Communication
A typical extension project takes about three months, though timelines vary depending on the size and complexity. To minimize disruption, Halligan Construction often completes the extension before integrating it with the existing structure, reducing dust and mess in lived-in areas.
Frequent communication with clients also helps manage expectations regarding timelines.
A Recent Project Highlight
One memorable project involved converting a detached pool house into an integrated part of a brick veneer home. Brenton describes the work as “very cool,” as they expanded the home and joined it with the pool house under a single roofline.
The project’s complexity showcased Halligan Construction’s dedication to bringing unique client visions to life.
