From a knock-down rebuild to a new estate pad, each service has its own page with the detail.
Glenhaven sits about 34 kilometres north-west of the city. Locals place it by Glenhaven shops, Glenhaven Reserve and Cattai Creek gullies. It's ringed by Castle Hill, Dural, Kenthurst, Annangrove and North Kellyville. What's changing: pools, granny flats and rebuilds on the big blocks.
Most blocks in Glenhaven, around Glenhaven shops, are 1980s–90s large brick-veneer homes and semi-rural blocks on leafy ridges. Near Glenhaven shops, knock-down rebuilds are the running theme. On a Glenhaven block that usually means pool digs, retaining walls and granny flat and shed pads.
Out toward Glenhaven shops, Glenhaven sits on Shale over sandstone on rolling ridge blocks with rock in the gullies. Sandstone sits close to the surface around Glenhaven Reserve, so a Glenhaven cut is sawn at the boundaries and broken out for anything deep. Around Dural, the clay is reactive, so fill goes in in compacted layers.
In The Hills Shire Council, Glenhaven around Glenhaven shops sits under bushfire controls, so the dig follows the approved plans. Access to Glenhaven is off Glenhaven Road or Old Northern Road; there's a side gate wide enough for a mini, near Castle Hill.
Every job follows the same sequence, whether it's a single trench or a full site cut.

See the whole Hills →It depends on the volume of material, the ground (shale over sandstone on rolling ridge blocks with rock in the gullies), access for the machine and how far spoil has to be carted. Every job gets a written quote after a site look, with the dig, cartage and cleanup spelled out, so you know what’s included before anything starts.
Usually, if the excavation is part of a build. Cut and fill beyond set limits, work near boundaries and anything on a lot with a flood, bushfire or heritage overlay needs approval as part of the DA or CDC. We work to the approved plans; check with your certifier before the dig is booked.
A trench, pool dig or single pad is a day or two; a knock-down site cut or a basement runs longer and depends on volume, ground and weather. Dates come with the quote, not after.
Yes. Shale over sandstone on rolling ridge blocks with rock in the gullies. North of Glenhaven and down in the gullies, sandstone is usually within the first metre, ripped where it’s weathered and broken where it’s solid. It’s in the quote when the site look finds it.
The block is benched: cut into two or three levels to the engineer’s plan, with retaining walls where the levels meet, so the new house sits on a flat pad instead of on fill. Cut and fill on slopes is regulated, so it goes through the approval with the retaining design.
Yes, and it’s the standard Hills pool. The shell sits on a bench cut into the hillside, with a cut for the retaining wall on the uphill side and the downhill side formed. The pool builder’s engineer decides the bench, and the site look decides the machine.
Yes. House and shed pads cut into the ridge, dams shaped in clay or cut into rock, and long driveways boxed and based. Tree and bushfire rules apply across the northern acreage and are checked before anything starts.
Reactive clay. It swells in wet winters and shrinks in dry summers, and anything poured on loose or uncompacted fill moves with it. A pad cut and filled in compacted layers to the engineer’s spec is what stops the new slab doing the same thing.
