Three kinds of Castle Hill home
Older brick homes near the centre. Streets around the original village and toward Baulkham Hills hold 1970s and early 80s brick and brick-veneer houses. Bathrooms are compact, often with the toilet in a separate room next door and a shower over a built-in bath. These homes predate 1990, so an asbestos test comes before demolition.
Large 1990s family homes. Further toward Cherrybrook and West Pennant Hills, the double-storey homes are bigger, with an upstairs main bathroom, a master ensuite and a powder room downstairs. These are generally sound rooms with dated finishes and tired showers, and they are the classic upgrade job.
Townhouses and apartments. Medium-density housing around Castle Towers, Showground Road and the Castle Hill and Hills Showground stations has grown quickly since the Metro opened in 2019. Newer apartments still have builder's defect warranties in place, while older townhouse complexes are coming up to their first bathroom renovations.
What Castle Hill homeowners upgrade
- Separate toilet rooms combined with the bathroom in the older homes, for a larger single room.
- Corner spas removed in 1990s homes, making way for a full-width walk-in shower.
- Ensuites widened into the walk-in robe.
- Powder rooms refreshed before selling, since they are the room buyers see first.
- Townhouse bathrooms modernised within strata rules.

Council
Castle Hill falls largely within The Hills Shire. Internal renovations that do not affect structure are usually exempt development, but heritage-listed properties and structural changes need a closer look.
