IS YOUR PROPERTY READY FOR A GRANNY FLAT?
Monstructions specialises in building granny flats in Artarmon’s established post war homes, delivering quality secondary dwellings that complement the character of this leafy North Shore suburb. We’re proud to serve homeowners throughout Artarmon, Chatswood and Willoughby with our licensed team handling everything from DA approval through to handover.
Artarmon Granny Flats Built Around Your Property
Artarmon features predominantly post war homes from the 1950s and 60s, with many original residences on generous blocks of 600 to 800 square metres. These established North Shore properties typically offer side access and deep backyards, making them ideal candidates for secondary dwellings. The level to gently sloping blocks provide straightforward construction conditions for granny flats.
We build granny flats throughout Artarmon, Mosman, Chatswood, Willoughby, Lane Cove and Northbridge, bringing extensive knowledge of Lane Cove Council requirements and approval processes. Our designs are specifically tailored to suit North Shore block dimensions and heritage considerations common in this established area. From compact studios to full two bedroom dwellings, we deliver quality secondary accommodation across the lower North Shore.
The Artarmon property market remains strong with median house prices exceeding $2.5 million, making granny flats a strategic investment for homeowners. Rental demand is driven by proximity to the train station, arterial roads and commercial centres, with quality granny flats achieving $650 to $800 per week. Building now allows homeowners to capitalise on sustained rental demand in this highly sought after North Shore location.
