How To Choose The Right Floor Plan

Your Complete Guide to Finding the Perfect Floor Plan

Designing or choosing the right house floor plan is one of the most exciting steps in building your dream home — but it can also feel overwhelming.
At Australian House Designs Group (AHDG), we’ve helped thousands of homeowners, builders, and investors find or adapt designs that fit their lifestyle, site, and budget perfectly.

Below, you’ll find our expert tips for selecting the right floor plan — plus a simple step-by-step guide from selecting your design to building your new home.

🧱 1. Understand Your Block of Land

Before choosing a house design, make sure you’ve carefully considered your site conditions:

📏 Lot Size & Shape – Will your home fit comfortably on your land?
🏞️ Site Features – Look for obstacles like easements, sewer lines, and existing trees.
🌞 Orientation & Sunlight – Consider where natural light will enter throughout the day.
🚗 Driveway Placement – Think about access and street frontage early.

💡 Tip: Always review your council’s covenants and building envelopes before finalising your design to avoid costly changes later.

🛋️ 2. Focus on Functionality & Lifestyle

Your home should reflect how you live — now and into the future.

👨👩👧👦 Family Needs – How many bedrooms and bathrooms will you need? Will your family grow, or might elderly relatives move in later?
🎉 Entertaining – Love hosting? Consider open-plan layouts, outdoor alfresco areas, and a large kitchen with an island bench.
🧒 Children’s Zones – Plan for play areas, extra storage, and separate living spaces.
🚪 Flow & Furniture – Visualise how you’ll move through each room — and whether your existing furniture will fit comfortably.

🧭 A well-planned layout is one that feels natural and supports your daily routines.

✍️ 3. Create a Wishlist

Grab a notebook and start a “Must-Haves, Nice-to-Haves, and Avoids” list:

✅ Must-haves: essential features (bedrooms, layout style, garage, etc.)
💭 Nice-to-haves: dream features like a butler’s pantry or study nook
🚫 Avoids: things you dislike in your current or past homes

📸 Visit display homes for inspiration, take photos, and jot down what stands out. Over time, you’ll see patterns emerge — that’s your dream layout taking shape!

📐 4. Know What You’re Looking At

Floor plans use many abbreviations and symbols — and not all are obvious.

🧾 Common examples include:

• WIR = Walk-In Robe

• WC = Water Closet (toilet)

• FFL = Finished Floor Level

If you’re unsure about what something means, ask your builder or designer — or email our team anytime at info@ahda.net.au for quick clarification.

💡 Understanding your plan helps you avoid costly misunderstandings during construction.

💰 5. Know Your Budget

It’s easy to fall in love with a dream home, but costs can vary dramatically based on:

• Multi-storey or split-level designs

• Retaining walls or difficult site slopes

• Landscaping and driveway requirements

🎯 Before committing, speak with a builder to get an approximate price range.

Before you meet a builder, buy a Preview Set for each design you’re considering. It gives you dimensioned floor plans and external elevations to discuss the layout, possible site fit and a preliminary cost range. Compare options before paying for editable CAD files or arranging site-specific working drawings.

Browse house plans and choose the Preview Set option on the design you prefer, then bring the PDF to your builder. A Preview Set is for reviewing a design and discussing options; it is not a construction or approval drawing. Ask a qualified local professional to check your block and requirements before building.

Want to compare styles and purchase options first? Use our house designs for sale guide to narrow your choices before shopping.

Once you have chosen a design, you can buy its Working Set with editable CAD files and take them to your own builder or designer. They can modify the layout, dimensions and features to suit your budget, block and requirements. Check the files included on the individual product listing before buying; your chosen professional must complete the site-specific drawings and any approvals needed before construction.

⚖️ 6. Check Local Regulations

Before finalising your design, confirm your local zoning and council requirements:

🏛️ Height restrictions
📏 Minimum/maximum floor area
🏠 Building envelopes and setbacks
📜 Covenants or design guidelines

These factors determine what you can build — and ensure your chosen floor plan meets approval requirements from the start.
