Tasked with fulfilling the residential obligations of four commercial developments in Westminster, this project involved integrating cutting-edge roof access solutions across five blocks, ranging from historically listed buildings to those constructed in the 1980s.

Our challenge was to devise roof access solutions tailored to the unique requirements of each building, enhancing both the aesthetic and functional aspects of the development. These solutions were designed to offer abundant ventilation and natural light, all while maintaining the architectural integrity of the varied structures.

To address this, Surespan supplied multiple SLHG Glazed Sliding Access hatches. These electrically operated sliding glazed roof hatch skylights, custom-made to the client’s specifications.

Measuring 15 feet 12 inches by 6 feet 4 inches, these hatches featured an electrically driven opening motor, ensuring ease of use and reliability. The design offered 7m² of free airflow, thanks to its sliding mechanism that eliminated any obstruction to ventilation. We used laminated and heat-strengthened low iron glass to L40, maximising both safety and light penetration.

In addition to the sliding hatches, we also provided a fixed skylight measuring 16 feet 1 inch by 6 feet. This thermally broken multi-pane rooflight was designed to further augment natural daylight within the development, enhancing the living spaces with warmth and brightness.

Our bespoke skylight solutions not only met the client’s functional requirements but also contributed significantly to the aesthetic enhancement of the development. The seamless integration of our innovative designs with the diverse architectural styles of the blocks underscored our commitment to excellence and our ability to deliver tailored solutions in complex urban settings.
