A Small Lot House under most planning schemes in Brisbane are lots under 450sqm in size . Any extensions to these types of houses need to strictly comply with the provisions of the planning scheme or they will trigger development approval. Some of these provisions (very broadly) may be similar to the below*

  • 50% site cover maximum
  • 1.5m side setback
  • 6m rear setback
  • 25m maximum building length
  • Front setback within 20% of adjoining
  • 7.5m maximum height at eave with 8.5m maximum height

  • Lightweight structures

Most planning schemes will have a wide range of exempt extensions for Small Lot Houses and these may be applicable to your development. Please give us a call to discuss.

*note, these provisions will vary from planning scheme to planning scheme and we very highly recommend giving us a call to discuss your particular small lot situation.

Most houses built prior to Dec 31st 1946 are considered to be under demolition control. Any alteration to these types of houses require development approval. We deal regularly with this type of approval and can ensure a smooth turnaround.


Some development will not trigger a planning approval because of its use, rather due to the proposal of building work itself. Most common in Ipswich, certain development will require development approval for building works assessed against the planning scheme.


A centre activity use can encompass quite a wide range of activities including a shop, office, restaurant, church, venue, bar…etc. Depending on the zoning of your property it may trigger a development approval.
