Thinking about building a prefab home, but not sure where to start? Decide how many bedrooms and bathrooms you need first. This will help determine how much floor space you actually need – which, in turn, shapes the layout, flow, functionality and cost* of your home.

To make things simple, prefabricated house plans are often grouped by floor area. In this blog, we’ve used the following categories:

• 40-80m²
• 81-120m²
• 121-150m²

The good news? Advance Build offers floor plans across all these size ranges. We’re going to walk you through our different prefab home plans and give you our most popular examples in each of our floor plan ranges (Classic, Modern and Designer). 

Use it to compare and shortlist your ideas – and find a design to suit your:

• Lifestyle
• Budget
• Land size.

*Of course, other factors also influence cost (e.g. number of windows, bathroom / kitchen size, fittings etc.)

How to decide which prefab home floor plan is for you

Q&A: Choosing your prefabricated house plans

How do I choose the right prefab home plan?

Start by matching the number of bedrooms and bathrooms to your needs. Then think about your lifestyle and how that impacts your decision making. For example, whether you need a home office, space to entertain or a low-maintenance holiday home.

What prefab plan suits a small site?

Focus on compact prefab home plans (40-80m²). These designs (such as the Kemp 1 or Oasis 2) maximise space and are ideal for smaller sites, minor dwellings and granny flats. 

How does land size impact the floor plan I choose?

Your land size (and shape) generally dictate floor area and layout options. Advance Build can customise prefab home plans to fit your site, making the most of whatever space you have.

How do lifestyle needs influence prefab floor plans?

If you love entertaining, choose an open-plan layout with large living areas. Remote workers should consider including a study or multi-use space, while holiday homes generally need simple, low-maintenance designs.

How does budget affect prefab house plans?

Knowing your budget upfront helps you set expectations around floor size, finishes and fittings (to name only a few!). With Advance Build’s wide range of floorplans, you’ll find one to match your budget, style and site.
