One of the primary advantages of a garden room is the abundance of natural light and the opportunity to enjoy beautiful garden views. To capitalise on these features, consider the following ideas:

  • Large Windows and Doors: Install floor-to-ceiling windows and sliding or bi-fold doors to flood your garden room with natural light and provide easy access to your outdoor space.
  • Roof Lanterns: Incorporate a roof lantern or skylights to allow even more natural light to filter in, creating a bright and airy atmosphere.
  • Mirrored Walls: Strategically place mirrors opposite windows to reflect natural light and create the illusion of a larger space with even more windows.
