Urban Collection

The Urban Aluminium Roof Lantern Range is designed for modern spaces, with a sleek, minimalist profile that maximizes light flow. Made from high-quality aluminium with thermal breaks and energy-efficient glazing, these roof lanterns provide a stylish, low-maintenance solution that enhances both the aesthetics and thermal performance of your home.

Lonsdale

The Lonsdale aluminium roof lantern creates an impressive architectural centrepiece for spacious contemporary extensions and open-plan living areas. Measuring 2000mm × 2000mm (finished external kerb), its generous square four-pane design offers an expansive glazed opening, making it particularly suitable for larger kitchens, dining rooms and family living spaces where natural light is a priority.

As the largest square model in our Urban Collection, the Lonsdale combines striking proportions with slim 40mm aluminium framing and clean, minimalist detailing. Its symmetrical design makes it especially appealing when positioned centrally above a substantial kitchen island, dining area or seating arrangement, creating a strong architectural focal point while maintaining an elegant, balanced appearance.

Thermally broken aluminium profiles and energy-efficient double glazing help reduce heat loss, while the durable, low-maintenance construction offers lasting practicality. Available in a choice of frame colours and glazing options, the Lonsdale provides a sophisticated solution for homeowners seeking a large square aluminium roof lantern with contemporary styling. Supplied in kit form for assembly on site.
