Introduction
Deciding to extend your home is a monumental decision, filled with excitement and a little trepidation. Whether you’re expanding for a growing family, adding a new office, or simply increasing your living space, it’s crucial to understand the costs involved. PBS Carpentry & Maintenance, with our expertise in home extensions, is here to guide you through the cost breakdown, ensuring you have all the information you need to embark on this transformative journey.
Planning and Design Costs
The first step in any home extension project is the planning and design phase. This includes hiring an architect or designer to draft plans that meet your vision and comply with local regulations. In Melbourne, these professionals typically charge anywhere from 5% to 15% of the total project cost, depending on the complexity of the design. You’ll also need to factor in the cost of obtaining necessary permits, which can vary but generally range between $1,200 and $2,500.
Structural and Site Preparation
Once the plans are approved, the next step is preparing the site. This includes tasks such as site clearing, excavation, and laying the foundation. The cost for this phase can be significant, often accounting for 10% to 15% of the total budget. It’s essential to have a solid foundation to ensure the longevity and stability of your extension.
Construction Costs
The bulk of your budget will inevitably go towards construction. This includes the cost of materials like timber, bricks, and roofing, as well as labour costs. On average, you can expect construction costs to range from $1,800 to $3,000 per square metre. This range depends on the quality of materials and the complexity of the build. Custom features and high-end finishes will naturally push costs towards the higher end of the spectrum.
Plumbing and Electrical
Integrating plumbing and electrical systems into your new extension is another critical phase. Plumbing costs can range from $2,000 to $5,000, depending on the complexity of the installations required. Electrical work, including wiring, lighting, and outlets, typically costs between $70 and $100 per hour for a qualified electrician. These figures can add up quickly, especially if you’re installing new bathrooms or kitchens.
Interior Finishes and Fixtures
Here’s where you can truly make your mark. Interior finishes and fixtures include flooring, cabinetry, countertops, and painting. Depending on your taste, you may opt for premium finishes that will increase the overall cost. For instance, timber flooring may set you back about $100 to $150 per square metre, while tiling can range from $90 to $160 per square metre. Custom cabinetry and countertops can range widely, from a few hundred to several thousand dollars, depending on materials and craftsmanship.
Landscaping and External Works
Don’t forget the exterior! Landscaping and any external works, such as creating a deck or patio, are often overlooked but can add a significant amount to the final bill. Typically, setting aside 5% to 10% of your budget for these works is a good rule of thumb. A well-landscaped garden or a cosy patio can significantly enhance the aesthetic and functional appeal of your home extension.
Unexpected Costs
Despite meticulous planning, unexpected costs are almost inevitable. Structural issues, changes in material prices, and unforeseen delays can all impact your budget. It’s wise to allocate a contingency fund of around 10% to 15% of your total budget to cover these surprises. This way, you’re not left scrambling when something unexpected arises.
Labour Costs
Labour costs, often the elephant in the room, can vary greatly. Skilled tradespeople such as carpenters, electricians, and plumbers will charge hourly or flat rates depending on the scope of their work. On average, carpenters in Melbourne charge between $50 and $70 per hour. Remember, investing in skilled labour is crucial for achieving a quality finish and avoiding costly repairs down the line.
Project Management
Managing a home extension project can be a full-time job. For those of you with busy schedules, hiring a project manager might be a wise decision. Project managers typically charge between 5% and 10% of the total project cost. Their expertise can streamline the process, ensure timely completion, and mitigate potential issues, offering peace of mind.
