A modern kitchen extension with white floors and walls and countertops, with a small wood table in the center next to a window seat and sliding doors leading to a patio area.

With the constant rise in build and material costs, we're finding that most new kitchen extension trends breaking through are not bigger, grander or more luxurious — instead it's about making a new extension feel connected and part of the original home, being more considered with color and materials and creating cozy corners and moments to enjoy with family and friends.

With that in mind, a more humble, traditional look is gaining popularity — we're seeing less open-plan, super contemporary square spaces (and definitely less bifold doors), and more of the two opposing aesthetics working together in harmony.
