Home Extensions
Add the space your family needs — from ground-floor additions to full second-storey builds — without leaving the neighbourhood you love.
Expand Your Home, Elevate Your Lifestyle
Melbourne families grow, needs change, and the home that once felt spacious can start to feel cramped. A well-planned home extension is one of the most effective ways to gain the extra bedrooms, living areas, or functional space you need — all while staying in the suburb you have put down roots in.
At Segval Pty Ltd, we design and build home extensions that integrate seamlessly with your existing structure. Whether you are looking to push out at ground level, add a second storey, or enclose an outdoor area to create a year-round living space, our team manages every stage from concept sketches through council permits to final handover.
We have completed extensions across Melbourne's inner south-east, bayside suburbs, and eastern corridors. Each project is shaped by the specific character overlays, setback requirements, and heritage considerations that apply to your property's municipality — from Glen Eira and Kingston to Boroondara and Monash.
Our construction methodology ensures minimal disruption to your household. Where possible, we stage the build so you can continue living in the home throughout the project, with clear separation between construction zones and your living areas.
- Ground-floor rear and side extensions to maximise your block
- Second-storey additions with engineered structural solutions
- Open-plan living, dining, and kitchen reconfigurations
- Full council permit lodgement and management
- Matched materials and finishes for a seamless look
- Comprehensive building warranty under Victorian legislation
Types of Home Extensions We Build
Ground-Floor Extensions
A ground-floor extension is typically the most straightforward way to add space. By extending into the rear or side yard, we can add new bedrooms, expand the kitchen and living areas, or create a dedicated home office or studio. We assess your site coverage limits, overlooking regulations, and garden setback requirements before putting pen to paper, ensuring the design is approvable and buildable.
Second-Storey Additions
When your block is too small to extend outward, going up is the logical solution. A second-storey addition can double your living space without sacrificing any garden area. Our structural engineers assess the existing footings and framing to determine what reinforcement is needed, and our builders execute the work with precision to protect the ground-floor structure below.
Outdoor-to-Indoor Conversions
Melbourne's variable weather means an unenclosed deck or patio often sits unused for months at a time. We convert these spaces into insulated, weathertight rooms complete with glazing, heating, and integrated connections to the existing floor plan — giving you functional square metres you can use year-round.
What to Expect During Your Extension Build
Our process starts with a detailed site measure and feasibility study. We then produce concept plans, refine them with your input, complete working drawings and engineering, and lodge the building permit with your local council or a private building surveyor. Construction typically begins within two to four weeks of permit approval, and we provide a detailed programme so you know exactly when each trade will be on site.
