Builders in Charlestown

Extensions, renovations and decks across Charlestown, Kotara, Whitebridge and the surrounding suburbs.

Charlestown is mostly post-war and mid-century brick housing on decent-sized blocks, which makes it good territory for extensions. Plenty of three-bedroom homes here are ideal candidates for a fourth bedroom and ensuite, or for opening the back of the house into an open-plan living and outdoor area.

The blocks often fall away toward the rear, so a ground floor extension may need stepped footings or a suspended floor, and decks usually end up elevated with a compliant balustrade. Neither is a problem, but both need to be in the quote from the start rather than appearing later.

Being ten minutes from Edgeworth means we are on site quickly, which matters more than people expect when something needs a decision made that day.

We offer every one of our building services in Charlestown.

Local conditions that affect your build

Falling rear blocks
Common through Charlestown and Whitebridge. Affects footing design, deck height and whether a balustrade is required.
Established housing stock
Mostly 1950s to 1970s brick. Expect to find asbestos in eaves and wet areas on anything pre-1990, which needs licensed removal.
Complying development friendly
Most standard blocks here qualify for a Complying Development Certificate, so a well-designed extension can be approved in weeks rather than months.
