Maximizing Natural Light

Light and airy spaces feel larger and more inviting. Include windows and doors to optimize natural light:

  • Add full-length or casement windows for panoramic views and easy ventilation.
  • Consider installing a large picture window or French doors for a focal point and access to the outdoors.
  • Don't forget skylights or roof windows for overhead natural light, perfect for loft conversions.
