What Plans Do You Need to Send Your Building Inspector?

A Guide to the Main Construction Plan Set Used for Stage Building Inspections

If you're building a new home, you've probably received a folder full of drawings from your builder. Floor plans, engineering plans, electrical layouts, landscaping plans—it can quickly become overwhelming.

One of the most common questions we get asked at BSPI Inspections is:

"What plans do I need to send through for a quote?"

The good news is you don't need to send every drawing your builder has provided.

The main set of plans we require to prepare your quote is your construction plan set (sometimes called your architectural plans). This is the primary set of drawings your building inspector will use throughout your stage building inspections.

In this guide, we'll show you how to recognise the correct plan set, explain the key drawings inside it, and show you how they're used during construction.

Watch our 30-second guide below, then keep reading for a more detailed breakdown.

What Is a Construction Plan Set?

When building a home, your builder may provide several different sets of drawings throughout the project.

These can include:

Structural engineering plans
Slab engineering plans
Electrical layouts
Energy efficiency reports
Landscaping plans
Hydraulic plans

While all of these documents serve an important purpose, the construction plan set is the main document we need when preparing your quote for stage building inspections.

Think of it as the master reference for your home. It contains the drawings that show how your house is intended to be built, allowing your building inspector to compare the completed work with the approved design.

Inside this plan set you'll find dozens of pages, but there are four drawings every homeowner should recognise.

1. Floor Plans

📷 Example Floor Plan: Construction floor plan used during stage building inspections.

The floor plan is usually the drawing people are most familiar with.

It provides a bird's-eye view of your home and shows how every room fits together.

A typical floor plan includes:

Room names
Internal walls
Door and window locations
Overall dimensions
Garage layout
Outdoor living areas

How does a building inspector use a floor plan?

Throughout your stage building inspections, the floor plan acts as the roadmap for your home.

It helps your inspector:

Understand the home's layout.
Locate rooms quickly during the inspection.
Compare wall and room locations and measurements with the approved plans.
Reference specific areas when writing your inspection report.

Although it may look like a simple drawing, it's one of the most frequently used pages throughout the entire construction process.

2. External Elevations

📷 Example External Elevation: External elevation drawing from a residential construction plan set.

External elevations show what your completed home should look like from the outside.

Most construction plan sets include:

Front elevation
Rear elevation
Left elevation
Right elevation

These drawings provide information such as:

Roof shape and height
Window positions
External doors
Brickwork or cladding
Render locations
Finished ground levels
Overall appearance of the home

How does a building inspector use external elevations?

External elevations help your inspector compare the home's appearance with the approved design.

They're commonly referenced throughout construction to ensure the finished home generally reflects the plans provided by the builder.

3. Internal Wet Area Elevations

📷 Example Bathroom Elevation: Bathroom internal elevation showing fixtures and tile layout for a stage building inspection.

These are some of the most important drawings in your construction plan set, yet many homeowners don't realise they exist.

Internal wet area elevations provide detailed views of rooms including:

Bathroom
Ensuite
Powder room
Laundry

Unlike the floor plan, these drawings show each wall individually.

They often include:

Shower niches
Shower screens
Vanities
Mirrors
Tapware
Towel rails
Accessories
Heights and dimensions

How does a building inspector use wet area elevations?

These drawings become particularly important during:

Pre Plaster & Enclosed stage inspections
Waterproofing inspections
Fixing stage inspections
Practical Completion Inspections

They allow your inspector to compare the completed wet areas with the approved design and confirm important fixtures and finishes have been installed as documented.

4. Kitchen & Laundry Elevations

📷 Example Kitchen Elevation from a Residential Construction Plan Set

Kitchen and laundry elevations provide detailed drawings of your home's joinery. While this example shows a kitchen elevation, you'll typically find similar drawings for the laundry within the same construction plan set.

These elevations provide much more detail than a floor plan, showing exactly how the cabinetry and fixtures should be installed.

A typical kitchen or laundry elevation may include:

Cabinet and drawer layouts
Overhead cupboards
Benchtops
Splashbacks
Appliance locations
Sink and tap positions
Cabinet dimensions
Joinery details

How does a building inspector use kitchen and laundry elevations?

Kitchen and laundry elevations are commonly referenced during enclosed, fixing stage inspections and practical completion inspections.

They allow your building inspector to compare the installed joinery, cabinetry, appliances and fixtures with the approved plans and identify any obvious discrepancies before handover.

Although the image above shows a kitchen elevation, your construction plan set will often include separate elevation drawings for the laundry and other joinery areas throughout the home.

Why Does Your Building Inspector Need These Plans?

Your construction plans provide the primary reference point throughout every stage of your build.

Without them, an inspector is simply looking at a house.

With them, your inspector can compare what has actually been built with what was intended to be built.

Having the correct plans allows your inspector to:

Understand your home's design.
Locate rooms and construction details quickly.
Compare fixtures and finishes with the documented plans.
Produce more accurate inspection reports.
Identify items that may require further investigation.

A Quick Note About Contract Hierarchy

While construction plans are the primary drawings used throughout your build, they're not always the final authority.

If changes have been made during construction, there may be signed variations or contractual changes that override the original plans.

Generally, the order of precedence is:

The most recent signed variation
The signed building contract and its schedules
The construction plans

So, if you notice something built differently from what's shown on the plans, it doesn't automatically mean it's a defect. It may simply reflect an approved contractual change between the builder and the homeowner.

Providing your construction plan set before your inspection also allows your inspector to familiarise themselves with your home before arriving on site, making the inspection more efficient.

Do I Need to Send Any Other Plans?

For your initial quote, your construction plan set is usually all that's required.

Once you've booked your first stage building inspection, it's also helpful to send:

Slab engineering plans (before your pre-slab inspection)
Structural engineering drawings (if available)
Any amended construction plans (most up to date set)
Updated engineering drawings if changes have been made

Using the latest revision helps ensure your inspection is completed against the most up-to-date information available.

Final Thoughts

Understanding your construction plans isn't just helpful for your building inspector—it's one of the best ways to stay informed throughout your build.

Once you know how to recognise a floor plan, external elevations, wet area elevations and kitchen elevations, you'll have a much better understanding of the drawings your builder is working from and the documents your inspector refers to throughout each stage of construction.

If you're requesting a quote for stage building inspections, simply send through your construction plan set, and we can take care of the rest.

Frequently Asked Questions

Do I need to send engineering plans for a quote?

No. For a quote, your construction plan set is usually all we need. If you book a pre-slab inspection, we'll also ask for your slab engineering plans if they're available.

What if my builder issues revised plans?

Always send your inspector the latest revision. Updated drawings help ensure your inspection is completed against the current design.

Can I just send the floor plan?

No. While the floor plan is important, the full construction plan set provides the information needed to accurately assess your build and prepare your quote.
