    Monterey Granny Flats Built Around Your Property

    Monterey features a mix of post-war homes and renovated properties on generous blocks, many within walking distance of Botany Bay. The typical block size ranges from 550 to 700 square metres, providing excellent scope for a rear or side granny flat. These near-water homes with established gardens are ideal for adding a secondary dwelling without compromising the main residence.

    We service Monterey, Brighton-Le-Sands, Kogarah, Ramsgate, Sans Souci and Rockdale with expert granny flat construction. Our team has extensive knowledge of Bayside Council requirements and designs that suit local block layouts. Whether you need a studio, one bedroom or two bedroom granny flat, we tailor each project to maximise your waterside block’s potential.

    The Monterey property market remains strong due to its bayside location and proximity to beaches, parks and local amenities. Rental demand is high, with granny flats achieving $450 to $600 per week depending on size and finishes. Building a granny flat now lets you capitalise on this demand while adding substantial value to your property.
