A-Frame House Extensions for your dream home in Melbourne

Nestled among the picturesque landscapes of Melbourne, A-frame houses stand as symbols of rustic charm and cosy living. These triangular dwellings, characterised by their steeply pitched roofs and open floor plans, evoke a sense of connection to nature and offer a tranquil retreat. For those fortunate enough to call an A-frame house their home, the desire to expand their living space without compromising the unique character of their residence often arises.

The Architectural Style of A-frame House Extensions

A-frame house extensions aim to seamlessly blend with the existing architectural style, preserving the rustic charm and natural aesthetic that define these beloved dwellings. Careful consideration is given to maintaining the triangular roofline, large windows, and open-concept design, ensuring that the extension complements the original structure and enhances its functionality.

Types of A-frame Home Extensions

Extending your home allows you to expand your living space, improve functionality, and elevate your lifestyle. Extensions come in a variety of home styles and configurations, each offering unique advantages and suited for specific purposes.

Single-Storey Extension

A ground-floor extension is a versatile and popular choice for homeowners seeking to add more space. These extensions seamlessly blend with the existing structure, often in the form of a side or rear extension. Their primary advantage lies in providing additional ground floor living space in an A-frame style, catering to a variety of needs, including:
  • Creating an Extra Bedroom: A ground floor extension can provide the perfect solution, accommodating a new bedroom with ample space for sleeping, storage, and personal belongings.
  • Establishing a Home Office: With the rise of remote work, a dedicated home office has become an essential space. A single-storey extension can provide a tranquil and well-equipped workspace, ensuring focus and productivity.
  • Enlarging Living Areas: Craving more open-plan living spaces for social gatherings and family bonding? Expand your living room, dining area, or kitchen for a sense of spaciousness and connection.

Double-Storey Extension

An upper-storey extension offers maximum space expansion, adding living areas to both the first floor and the second floor. A two-storey extension is particularly well-suited for larger homes and families seeking substantial space gains. The benefits of double-storey extensions include:
  • Creating a Master Suite: Elevate your living experience with a luxurious master suite, incorporating a spacious bedroom, an opulent ensuite bathroom, and a walk-in closet.
  • Adding a Bedroom: A growing young family or frequent guests can be accommodated with an additional bedroom, providing comfort and privacy for all occupants.
  • Establishing a Home Office and Living Space: Combine the functionality of a home office with a dedicated living area. This allows for a versatile space that can transition from work to relaxation.


The A-frame Home Extension Process

Collaborating with Extensions Unlimited ensures a smooth and successful A-frame home extension process. The process typically involves:

Initial consultation

Our experienced team takes the time to understand your vision, lifestyle requirements, and budgetary constraints. This collaborative approach ensures that the extension aligns with your aspirations and integrates with the existing structure of your home. The initial meeting with your professional home extension designer is at no charge. At this meeting, you will have the opportunity to discuss your thoughts, ideas and requirements with our house extension expert.

Concept design

The creativity and attention to detail that our designers display in their work will make you delighted. All their ideas are based on what you want out of your addition. We want to ensure that you love your new extension and get the most functionality possible out of it. This means we might suggest a tweak here or there to maximise the features of your home, or to allow better movement and liveability throughout the space. But we will always listen to you fully before making our comments.


Drawing on their wealth of knowledge and experience our team can make informed suggestions and give great advice and feedback regarding the viability and indicative costs of the house extension being discussed before you consider moving forward with more formal designs and costings.

Council approval for planning permissions

At this planning stage, we organise compliance for all building regulations from your council. They will require building permits, as well as a host of reports including soil reports and bushfire reports, amongst others. We’ll get approval for your house addition by directly negotiating with the council on your behalf. We’ll also take care of any fees necessary to meet all council requirements. All this is fully covered in the fixed price for your renovation.

Construction phase

You will be excited to see your new house extension gradually come to life in the construction stage. We ensure all our tradespeople are fully trained and have completed an occupational health and safety course. All our constructions are regularly inspected by independent surveyors who issue reports during the progress of the works, as well as a final certificate upon completion. All our electricians and plumbers are fully certified and licensed to ensure the highest calibre of work. Our company project managers are qualified professionals who are always available for you if you have questions. Any required scaffolding will be erected by qualified riggers to ensure safety for you and your family. Company tarpaulins are also used to protect your home and the new addition.


Once the construction is complete, you can start enjoying the new space and improved lifestyle that your extension provides. The extension stands as a testament to our commitment to excellence and customer satisfaction.

Benefits of an A-frame House Extension

Adding an extension with an A-frame style to your existing home can bring a multitude of benefits that enhance your living experience, boost the value of your property, and cater to your lifestyle needs.

Increased Space

One of the most compelling benefits of an A-frame addition is the ability to alleviate spatial constraints and create much-needed extra floor space. Whether you’re seeking an additional bedroom to accommodate a growing family, a dedicated home office to support remote work arrangements or a larger living area for social gatherings and shared activities, a well-designed extension can seamlessly integrate with your existing house, providing the space you need to live comfortably and fulfil your lifestyle aspirations.

Improved Lifestyle

A home extension not only expands your living space but also elevates your lifestyle by enhancing functionality and comfort. By creating open-plan layouts that maximise natural light flow, incorporating A-frame amenities and fixtures, and thoughtfully integrating indoor and outdoor spaces, a well-executed extension can transform your home.

Increased Value

A well-conceived extension can significantly increase the value of your property, making it a sound investment for the future. By expanding the usable square footage, improving the overall aesthetics and functionality of your home, and enhancing its appeal to potential buyers, successful A-frame extensions can boost your property’s value, potentially yielding substantial returns when it comes time to sell.

Strategic Design Decisions

Extensions Unlimited helps you make strategic design decisions that resonate with current market trends and buyer preferences to maximise the value and desirability of your home. This could include incorporating features such as skylights for natural light, open kitchens or adding bathrooms, and spacious living room that cater to contemporary lifestyles.

Extensions Unlimited’s team of experienced designers carefully selects materials, colours, and architectural elements that harmonise with the character of your A-frame home, ensuring a seamless transition between the old and new.
