Contour and Detail Surveys in Baulkham Hills
Contour and detail surveys throughout Baulkham Hills and The Hills Shire, where blocks are generous, gardens are established and trees are protected.

Local Knowledge
Baulkham Hills sits on elevated, gently undulating land in The Hills, with sloping blocks, mature canopy and ridgeline drainage. Level changes are modest but consistent, so contour capture is worth doing properly on almost every site.
Granny flats are the common job here, and on these blocks the decision usually comes down to two things: the fall across the rear yard and which trees have to stay.
We work throughout Castle Hill, Winston Hills, Bella Vista and the wider Hills District.
Council Requirements
The Hills Shire Council requires a current detail and level survey for development applications, with close attention to tree retention and slope on its larger residential lots. Plans should reference Australian Height Datum and show existing trees, structures and levels clearly.
Property Types
Large family homes, granny flat sites, townhouse developments, sloping residential blocks, established gardens.
FAQs
Do the trees have to be on the survey for a granny flat?
Yes, and that is usually the part that decides where the granny flat can go. We locate trunks and canopy spread for anything significant.
How does the slope change things?
A sloping block means cut and fill, and the council assesses height from existing ground level, so your levels need to be accurate before the design starts.
Will the plan show drainage easements?
Yes, any easement affecting the land is shown along with visible services and pits.
