• Second Storey Additions - Maximise your block without losing valuable yard space. These additions are perfect for adding bedrooms, bathrooms, or a master suite, significantly increasing your property's value. Typical cost: $4,000-$6,000/m²
• Rear Extensions - The most sought-after type of home extensions in the Inner West, perfect for updating modern kitchens and living areas while maintaining your home's street presence and heritage character.
• Side Extensions - Ideal for narrow blocks in the Inner West, these extensions add width to cramped living areas, hallways, or bedrooms while adhering to boundary setbacks and heritage overlays.
Our home extensions come with comprehensive Design & Construct services, management of council approvals, expertise in heritage compliance, and fixed-price quotes with no hidden costs. We manage all BASIX and NatHERS requirements, work with Sydney Water and local utilities, and ensure compliance with current NCC and Building Code standards.
