How to read a floor plan, what questions to ask, and why it's important for off the plan property buyers

Arguably floor plans matter more in off the plan property than any other type of property.

In established markets, the floorplan is the floor plan. That's it, barring renovations.

But in the off the plan market, there a number of factors to consider when analyzing floor plans, and a number of questions to ask agents and developers when discussing buying an off the plan property.

First there's the floor plan size.

Floor plan sizes advertised by agents or developers can differ hugely state by state, so it's important to understand whether you are being pitched a property's internal size, or total size.

Internal size is the measurement of the internal floor area of an apartment, and is typically measured in square metres (m²). External size is the measurement of the external dimensions of an apartment, be it a courtyard or a balcony, but sometimes it can include a parking space or storage cage.

Generally, off the plan apartments are advertised with their internal size, as this is the size that you will have to work with when furnishing and decorating your new home. It's important to be aware of external size, however, as this will give you an indication of the overall size of the building and how much outdoor space you will have access to.

When considering internal vs external size, it's important to keep in mind that internal size may vary slightly from the advertised size due to the internal walls of the apartment. External size, on the other hand, is usually accurate to the advertised size as it's based on the overall dimensions of the building.

Another thing to consider when analyzing floor plans in off the plan property is that floor plans aren't necessarily set.

The majority of developers, providing construction is still at its early stages, will allow buyers to customize their floor plan to suit their lifestyle.

It might be that you want to move a bedroom or bathroom, or re-orientate the living area. This generally isn't a problem for developers as long as the moving of internal walls doesn't impact the building structurally, and the redesign all occurs within the same floor plate size of the original apartment.
