Contour and Detail Surveys in Hornsby

Contour and detail surveys throughout Hornsby and the Upper North Shore, where blocks slope towards bushland gullies and the canopy is protected.

Local Knowledge

Hornsby combines a relatively flat town centre with residential suburbs that fall away towards bushland gullies and creeks. Level changes across a block and protected canopy trees are the two things our plans here record most carefully.

Around the town centre the work shifts to unit sites, where street levels, basement access and neighbouring buildings matter as much as the block itself.

We work throughout Waitara, Asquith, Normanhurst and the wider Upper North Shore.

Council Requirements

Hornsby Shire Council requires a current detail and level survey for development applications, with particular attention to tree retention and slope on residential blocks. Plans should reference Australian Height Datum and show existing trees, levels and drainage clearly.

On residential blocks tree retention is usually the deciding factor, so canopy and trunk positions are recorded carefully.

Property Types

Town-centre unit sites, detached homes, sloping residential blocks, renovation projects, dual-occupancy developments.

FAQs

Does a bushfire-prone property need more detail?
Yes, because the assessment is calculated from slope and vegetation, and both have to be measured.

How does a sloping block change the design?
Height is assessed from existing ground level, so accurate contours decide what you can build before the architect starts.

Are the canopy trees included?
Significant trees are located with trunk and canopy, which is what council and your arborist need to assess what can be retained.

What do town-centre unit sites need?
Street and footpath levels, access points, neighbouring structures and services, because the design has to work against all of them.
