Every interior designer is taught early in their education that a good plan is the foundation of good design. But understanding why this matters often comes with experience.

When we look at an interior, the first things we notice are usually the visual elements: the colours, materials, furniture, lighting and overall aesthetic. These are the elements that make a space immediately appealing.

But good planning is different.

A good plan is something you may not consciously notice, but you feel it every day.

Good interior design begins with understanding how a space needs to function.

Before deciding how a room should look, the planning needs to consider how people will move through it, how they will use the furniture, where storage will be required, how different functions connect, and how much space is needed between them.

A living room may look beautiful in a 3D visual, but if the furniture restricts movement, the design has not been fully resolved.

A kitchen may have beautiful finishes, but if the working layout is inefficient, everyday use becomes inconvenient.

An office may have an impressive aesthetic, but if circulation, workstation placement and storage are poorly planned, the space will eventually become difficult to work in.

These are planning decisions and they have a greater impact on everyday experience than many of the decorative decisions that come later.

A plan needs to work not only on paper, but also when the space is occupied.

It needs to account for whether a wardrobe door can open comfortably, whether two people can pass each other, whether a dining chair can be pulled out without obstruction, whether there is sufficient clearance around furniture, and whether storage and services are positioned where they are actually needed.

These details may not appear dramatic in a 3D visual. Yet they are what make an interior comfortable and practical.

Good planning is about resolving these decisions before they become problems.
