What type of construction generally allows for more open spaces and light weight?

Frame construction is known for its ability to create more open spaces and lighter structural elements compared to other types of construction. This methodology uses a skeletal frame of vertical and horizontal members, typically made from wood or metal, which allows for greater flexibility in interior design.

The open framework not only provides a lighter structure but also allows for larger spans between supports, resulting in fewer walls and a more expansive, airy environment. This characteristic is advantageous for many buildings, such as homes and commercial spaces, where aesthetics and open layouts are important.

In contrast, more solid construction methods like concrete and steel, while providing strength and durability, often require additional supports or structural integrity solutions that can limit open spaces and increase weight. Therefore, frame construction stands out for creating functional and visually appealing spaces with minimal weight.
