Types of House Extensions We Offer in Sydney
No two homes are the same, so we offer a full range of house extensions in Sydney to suit different blocks, budgets and lifestyle needs. From adding space at ground level to building up with a new floor, we'll recommend the right approach for your property.
Ground Floor Extensions
Extend out into your yard to create larger living areas, open-plan kitchens, additional bedrooms or a new alfresco zone. Ground floor extensions for Sydney homes are a popular choice for families seeking more everyday living space.
First Floor Extensions
Add extra space over a portion of your current home, perfect for additional bedrooms, baths, or a parents' hideaway. First-floor extensions Sydney-wide are one of the most effective ways to gain space without extending your home's footprint.
Second-Storey Additions
Build a full extra level to significantly increase living space without losing your backyard. Second-storey additions, Sydney-wide, suit growing families who want more room while keeping their outdoor space intact.
House Extensions
Combine different extension types to create a complete home change, including extra living spaces, kitchens, bathrooms, and outdoor areas. This is our core house extensions service in Sydney, tailored to whatever combination of space your home needs.
Granny Flat Extensions
Self-contained spaces for extended family, guests or rental income, carefully integrated with your existing property. Our granny flat extensions, available Sydney-wide, complement your home and add long-term value.
Custom Design Extensions
Unique extension designs tailored to your block, views, orientation and lifestyle. Custom design extensions Sydney-wide options are ideal for homeowners with specific requirements or architecturally distinctive properties.
Whether you're considering a small home extension in Sydney or a major transformation with a new level, we'll help you choose the best option for your home and long-term plans.
Clear from start to finish
Our Home Extension Process in Sydney
Extending an existing home is a significant project, so a clear process is essential. Our structured approach keeps your house extension organised, compliant and on schedule.
- Initial Consultation & Site Visit — We assess how you use the space, your extension goals, site slope, access and the existing structure.
- Concept Design & Feasibility — We explore ground-floor, first-floor, second-storey and granny flat options, then show how the new spaces could connect with your home.
- Detailed Design & Documentation — Your preferred concept becomes detailed plans, engineering and documentation for approvals and accurate pricing.
- Approvals & Permits — We coordinate development applications, complying development certificates or private certifier approvals as required.
- Fixed Quote & Schedule — You receive a clear, itemised quote, realistic construction timeline and defined milestones.
- Construction & Extension Works — Licensed trades complete structural, carpentry, roofing, plumbing, electrical and finishing works to Australian Standards and approved plans.
- Finishing, Inspection & Handover — We complete fit-off and detailing, conduct quality checks and walk you through the extension before handover.
Simply put, we help you gain more room and functionality without leaving the location you love by managing design, permissions, construction and final handover.
What Affects Your Extension Cost in Sydney
Every house extension is priced around your specific project. Key factors include:
- Type of extension — ground floor, first floor, second storey or granny flat
- Size of the new area and number of rooms added
- Design complexity and structural requirements
- Materials, fixtures and finishes selected
- Site access and integration with your existing home
We'll walk through your budget and priorities during a free consultation, then provide a clear, itemised quote — with options to stage larger projects if that suits your investment plan better.
