Mansard Loft
Mansard loft conversions in Chessington are an ideal solution for maximizing the usable space in your loft. This conversion involves modifying the sloping part of the roof to create a flat surface, typically with a gable wall at one end. Additionally, windows are incorporated into the roof to flood the new space with natural light, creating a bright and airy atmosphere.
Dormer Loft
Dormer loft conversions in Chessington are highly sought-after due to their non-invasive nature. Unlike other types, no major structural alterations to the existing roof are needed. Instead, the roof is extended vertically, enhancing headspace and maximizing usable area. This results in a distinctive box-like structure along the roofline, while new windows ensure ample natural light floods the newly created space.
Rooflight Loft
Converting your loft with VELUX® windows in Chessington is not only cost-effective but also straightforward. No structural changes to the roof are required; all it takes is the installation of VELUX windows. These windows flood the newly converted space with abundant natural light, transforming it into a bright and inviting living area.
Hip to Gable Loft
Hip to Gable loft conversions in Chessington entail extending the bottom of the side slope vertically, resulting in a gable wall. This design significantly increases headspace, maximizing the available floor space. This conversion is exclusive to properties with hipped roofs.
