Residential development activity is lower than average in New Lambton Heights according to AreaSearch's national comparison of local real estate markets

New Lambton Heights had minimal residential development activity with 2 dwelling approvals annually between 2016 and 2020 (a total of 10 approvals over five years). These low development levels reflect the rural nature of the area, where development is typically driven by specific local housing needs rather than broad market demand. Note that the small sample size means individual development projects can substantially influence annual growth and relativity statistics.

Population forecasts indicate New Lambton Heights will gain 361 residents between 2021 and 2041 (from the latest AreaSearch quarterly estimate). Should current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and underpinning price growth.
