    Ultimo Granny Flats Built Around Your Property

    Ultimo features a diverse mix of heritage terraces from the Victorian and Federation eras alongside contemporary apartment conversions, with many established homes sitting on compact Inner West blocks. These smaller blocks typically range from 150 to 300 square metres, making them ideal candidates for thoughtfully designed compact granny flats. The area’s established residential streets offer rear lane access and clever site opportunities perfect for secondary dwellings.

    We build granny flats throughout Ultimo, Glebe, Chippendale, Pyrmont, Camperdown and Redfern, with extensive knowledge of Inner Sydney Council requirements and heritage considerations. Our designs are specifically tailored to suit the compact blocks and urban character typical of Inner West properties. Whether you need a studio, one bedroom or two bedroom granny flat, we deliver solutions that maximize your available space.

    Ultimo’s property market remains strong due to its proximity to the CBD, universities and Sydney’s tech precinct, driving consistent rental demand from students and young professionals. Quality granny flats in the area achieve weekly rents from $550 to $750 depending on size and finishes. Building a granny flat now capitalizes on this sustained demand while adding significant value to your established Inner West property.
