Modbury, including Tea Tree Gully North, Modbury Heights, Modbury North, and the surrounding areas, occupies gently hilly terrain in Adelaide's north-eastern suburbs approximately 14 kilometres from the CBD in the City of Tea Tree Gully. It is one of Adelaide's most complete suburban centres, anchored by the Tea Tree Plaza shopping precinct, with good public transport (O-Bahn), medical services, and schools. Homes range from 1960s and 1970s red brick on established lots to more recent dual-occupancy and infill townhouses on subdivided allotments.
The topography across Modbury is more varied than in the flatter northern suburbs. Many streets on the ridgelines and slopes require sloping driveway designs, and drainage planning is important — particularly on blocks that fall toward the house rather than away from it. We always confirm fall direction and drainage exit points as part of the free site measure, and we recommend channel drains in any situation where water could sit against the house footings or garage slab.
Soil conditions in Modbury are generally clay-based, with increasing rock presence toward the hills. On elevated streets near Modbury Heights, subgrade can transition from workable clay to shallow rock within 100–200mm of the surface, which affects excavation cost. We probe for rock as part of the site assessment for these streets and include any additional rock-break cost in the written quote before starting work.
Modbury has a strong renovation market. Homeowners in this area frequently request exposed aggregate driveways as part of modernisation projects on 1960s–1980s brick homes — the textured finish dramatically updates the street presentation of an older home. Coloured concrete in iron oxide red or charcoal is also popular for matching brick tones. Pool surrounds are another significant project type given the prevalence of in-ground pools in Modbury's larger backyard homes.
The City of Tea Tree Gully administers Modbury. Driveway crossover permits are required before any kerb modification. We lodge this application on your behalf. Call Javed on 0466 801 058 for a free measure and written quote within 48 hours.
| Finish | Price (installed) |
|---|---|
| Plain grey broom | $75–$95 / m² |
| Coloured / oxide concrete | $95–$120 / m² |

All prices are fully installed and include excavation, compacted roadbase, reinforcement mesh, concrete placement, finishing, control joints, curing compound, and site cleanup. For non-standard sites requiring extra excavation, removal of existing concrete, or heavy compaction work, an additional base preparation charge of $20–$50/m² applies — quoted separately before any work begins.
