In the quest to improve natural light within homes, architects and designers often turn to innovative solutions like light wells and skylights. While both serve to introduce sunlight into interior spaces, they’re distinct elements with unique features, benefits, and applications.
What is a Light Well?
A light well is an architectural feature designed to channel natural light into the interior spaces of a building. It’s essentially a vertical shaft that extends from the roof or upper levels down through multiple floors, often reaching basement or ground levels.
- Light wells can be open or covered with glass, allowing daylight to penetrate deep into the building.
Characteristics of Light Wells
- Vertical Shaft: They extend from the roof to lower floors — sometimes all the way to the basement.
- Open or Covered: Light wells can be open to the sky or covered with glass to protect from the elements.
- Reflective Surfaces: They’re often lined with reflective materials to maximize light transmission.
- Ventilation: Light wells provide natural ventilation, enhancing indoor air quality.
Pro Tip: Proper ventilation is essential to maintaining indoor temperatures and controlling moisture in your home.

What is a Skylight?
A skylight is a window installed in the roof or ceiling, designed to admit natural light from above. Skylights come in various shapes and sizes, including fixed, vented, tubular, and custom designs.
- They’re popular in both residential and commercial buildings for their ability to illuminate spaces that might otherwise lack sufficient natural light.
Characteristics of Skylights
- Roof Installation: They’re mounted on the roof or ceiling, directly admitting light from above.
- Variety of Designs: Skylights are available in fixed, vented, tubular, and custom shapes.
- Material: They’re typically made of glass or acrylic, often with energy-efficient coatings.
- Accessibility: Some skylights can be opened for ventilation.
Pro Tip: Skylight installation requires careful considerations from roof type and materials to size and placement.

Differences Between Light Wells and Skylights
While both light wells and skylights are designed to enhance natural light within buildings, they differ in several key aspects:
1. Structure and Design
- Light wells are vertical shafts that channel light through multiple floors, often lined with reflective surfaces.
- Skylights are windows installed in the roof or ceiling, allowing light to enter from above.
2. Installation
- Light wells require substantial architectural planning and construction, often integrated into the building’s initial design.
- Skylights can be more easily retrofitted into existing buildings.
3. Light Distribution
- Light wells distribute light vertically, reaching deeper into the building.
- Skylights directly illuminate the space beneath it, with light diffusion dependent on the skylight’s design and location.
4. Ventilation
- Light wells can provide natural ventilation if open to the sky or equipped with venting options.
- Some skylights can be opened for ventilation, enhancing air circulation.
Benefits of Light Wells and Skylights
While there are some distinctions between the two, light wells are a kind of skylight, and they share several important benefits, including:
- Enhanced Natural Light: They significantly increase the amount of natural light reaching lower floors and basements.
- Energy Efficiency: Each reduces the need for artificial lighting, lowering energy consumption.
- Improved Ventilation: Both can enhance airflow and indoor air quality if designed with venting options.
- Aesthetic Appeal: These features add architectural interest and a sense of openness to the interior space.
Choosing Between Light Wells and Skylights
The choice between a light well and a skylight depends on various factors, such as:
- The Building’s Design
- The Desired Amount of Natural Light
- The Specific Needs of the Space
Light wells are ideal for multi-story buildings or spaces where natural light needs to penetrate deeper levels. They are best suited for new constructions or major renovations due to the structural changes required.
Skylights are more versatile and easier to install, making them suitable for both new constructions and retrofits. They work well in single-story homes or rooms directly beneath the roof.
