A bigger extension does not automatically mean a better layout.
These are three mistakes I see far too often:
1. Positioning the media wall opposite windows or bi-fold doors, creating glare and reflections on the TV.
2. Pushing every piece of furniture against the walls and leaving a large, disconnected space in the middle.
3. Placing island seating directly in front of the fridge, turning one of the kitchen’s busiest routes into a constant obstruction.
A successful extension is not just about gaining more square metres. It is about planning how you will move through the space, where the furniture will sit and how the room will function every day.
Make these decisions before finalising walls, electrics and lighting. Fixing a poor layout later is expensive.
Save this post if you are planning an extension, and send me a message if you need help getting the layout right before building begins.
