1750mm x 1750mm Made to Measure Glass Flat Roof Window Lantern
Our 1750mm x 1750mm Square Gazebo Style Roof Lantern is a made-to-measure flat roof window lantern featuring four equal-sized sides for a balanced, traditional gazebo-style appearance. Designed to bring additional natural daylight into rooms beneath flat roofs, the raised lantern also creates an attractive architectural feature.
Ideal for flat roof extensions, kitchens, dining rooms, conservatories and garden rooms, the lantern is supplied as a complete system with the window frames, roof structure, guttering, your selected glass or polycarbonate roof and a decorative finial.
1750mm x 1750mm Square Roof Lantern
The stated 1750mm x 1750mm dimension is the internal frame size. Because the lantern is square, all four sides are equal, creating the symmetrical appearance associated with a traditional gazebo-style roof.
The overall dimensions of the complete lantern are larger once the uPVC window profiles and cill are included, so it is important to understand the measurements before constructing the supporting roof opening or upstand.

The roof lantern is supplied as a complete system with the main components required to create the finished structure.

1750mm x 1750mm Internal Frame Size
Important: the stated 1750mm x 1750mm size is the internal frame measurement. It is not the overall external dimension of the complete roof lantern.
The uPVC window profiles are approximately 70mm wide. This adds approximately 70mm to each side, or 140mm to the overall width and length.
The approximate external frame size for this lantern is therefore 1890mm x 1890mm.
The cill extends approximately 160mm on each side, adding approximately 320mm to the stated internal dimensions.
The approximate overall external cill size is therefore 2070mm x 2070mm.
1750mm x 1750mm Roof Lantern Dimensions
- Internal frame: 1750mm x 1750mm
- Approx. external frame: 1890mm x 1890mm
- Approx. external cill: 2070mm x 2070mm
Please check all dimensions carefully before constructing the roof opening, kerb or supporting upstand.
Square Gazebo Style Roof Design
The four equal sides create the distinctive square gazebo roof lantern design. The combination of vertical window frames and a raised pitched roof creates additional height and helps turn the roof lantern into a focal point within the room.
This symmetrical configuration is particularly suitable for square flat roof openings where a traditional roof lantern appearance is required.
Important Information About the Roof Configuration
Product photographs may show a smaller approximately 1m x 1m gazebo roof lantern. Larger lanterns require different roof configurations to provide the necessary strength and support.
For this reason, the exact roof configuration of the 1750mm x 1750mm lantern may differ from the smaller example shown in the product photographs. The final roof structure will be appropriate for the size of lantern being manufactured.
Glass Roof Lantern Option
Choose glass roof glazing for the clean appearance associated with a traditional glazed roof lantern. The raised glazed roof allows natural daylight to enter from above while creating an attractive feature over the room below.
Polycarbonate Roof Lantern Option
A polycarbonate roof is also available as an alternative to glass. Polycarbonate provides a lightweight and practical roofing option while retaining the distinctive raised gazebo-style lantern design.
Flat Roof Window for Extensions
The 1750mm x 1750mm roof lantern is particularly suited to flat roof projects where additional overhead daylight is required.
Suitable applications can include:
- Flat roof home extensions
- Kitchen extensions
- Dining areas
- Garden rooms
- Conservatories
- Orangeries
- Other suitable flat roof projects
