Planning a Development Application?
Preparing a development application requires more than completing a form. A strong DA submission needs clear planning strategy, accurate documentation, relevant supporting reports and an understanding of the approval pathway.
Senica helps project teams identify planning requirements, coordinate supporting documentation and prepare development application material that supports efficient assessment.
Whether you are planning a new dwelling, alterations and additions, secondary dwelling, multi‑residential development, commercial project or change of use, early planning advice can help reduce approval risk and improve project certainty.
Why Early DA Advice Matters
Planning issues identified during concept design are usually easier to resolve than issues discovered after plans and consultant reports have been finalised.
​
Early development application advice can help project teams understand site constraints, planning controls, documentation requirements and potential approval risks before significant design investment occurs.

This can reduce the likelihood of requests for additional information, redesigns, delays and documentation conflicts during the assessment process.

Planning Control Issues
Height, floor space, setbacks, zoning, overlays and other controls may affect approval pathways.
Documentation Conflicts
