When embarking on a new construction or renovation project, one of the most critical steps is reviewing your site documentation—particularly your block plan. Whether you’re building a new home, an extension, or preparing for council submission, a building block plan provides the foundation for every design and compliance decision. Yet, despite its importance, many homeowners and even developers make avoidable mistakes when reviewing their plans.
Below are some of the most common pitfalls to look out for—so you can approach your next project with clarity, confidence, and compliance.
Overlooking Scale and Orientation
It might seem obvious, but one of the most frequent errors is neglecting to confirm the plan’s scale and the correct orientation of the property. Even a slight misinterpretation of boundaries or setbacks can lead to major compliance issues down the track. Always check that the plan includes a north point and that distances, boundary lines, and building envelopes are drawn accurately to scale.
Ignoring Site Levels and Gradients
Site levels and contours can dramatically affect the feasibility and cost of your build. Many people gloss over these details, only to discover later that their “flat” block requires significant excavation or retaining walls. Reviewing contours carefully helps ensure accurate drainage design, slab preparation, and site cut requirements.
Missing Easements and Service Lines
Easements, sewer lines, and stormwater drains are easy to miss on a plan—but ignoring them can lead to costly redesigns or council objections. Make sure all service infrastructure is clearly marked, and confirm there are no encroachments over easements. If in doubt, it’s wise to have a professional surveyor or planner double-check these elements before finalising approvals.
Failing to Cross-Check with Other Documents
Your block plan doesn’t exist in isolation. It should align seamlessly with architectural drawings, floor plans, and engineering documents. A common mistake is reviewing each document separately instead of comparing them side by side. Inconsistencies—such as differing boundary measurements or missing setbacks—can create major delays in the permit process.
Not Considering Future Development or Access
A well-thought-out review isn’t just about the current project. Consider how future structures, extensions, or landscaping may interact with your existing design. Many people forget to allow for vehicle access, pool installations, or outdoor spaces that may become difficult to add later due to setbacks or building envelopes.
Rushing Through Council Requirements
Every local council has specific requirements for block plans, including scale, title boundaries, easement labelling, and feature details. Failing to review these requirements carefully before submission can lead to rejection or requests for resubmission. Taking the time to verify that your plan meets local standards will save both time and money.
Neglecting Professional Review
Finally, one of the biggest mistakes is assuming a quick glance is enough. Even if you’re confident, it’s worth engaging a qualified surveyor or planning consultant to review your block plan. They can identify subtle discrepancies and ensure full compliance with council and building regulations.

Reviewing your block plan thoroughly is one of the simplest ways to prevent costly setbacks. By taking a detail-oriented approach and consulting experts where necessary, you can ensure your project runs smoothly—from planning through to completion. Remember, a building block plan isn’t just a formality—it’s the blueprint for your property’s success.
