Planed Larch 4 Pitch Pergola with Metal Corrugated Roof – Heavy-Duty Garden Shelter

The Planed Larch 4 Pitch Pergola with Open Roof is a visually striking garden structure designed to combine architectural balance with an open, light-filled feel. Built from smooth planed larch and engineered with heavy-duty timbers, this pergola delivers excellent stability while maintaining an airy, contemporary presence in your outdoor space.

Its four-sided, pyramid-style frame creates strong visual symmetry and evenly distributes weight across the structure, making it a reliable and attractive choice for gardens, patios, and entertaining areas where natural light and openness are a priority.

Open Roof 4 Pitch Design

The open roof design allows sunlight and airflow to pass freely through the pergola, creating a bright and welcoming environment beneath. This makes it ideal for relaxed seating areas, garden features, or training climbing plants and decorative lighting. The 4 pitch structure adds architectural interest while keeping the space feeling open rather than enclosed.

Smooth Planed Larch Construction

Crafted from smooth planed larch, this pergola offers a clean, premium finish with excellent outdoor performance. Larch is naturally durable and well suited to exterior use, providing long-lasting strength and resistance to the elements when correctly maintained. The planed finish enhances the pergola’s contemporary appearance and works equally well in modern or traditional garden designs.

Important installation information

This 4 pitch pergola kit includes components that require cutting to size during installation. This provides flexibility on-site but is best suited to installers comfortable with light cutting and adjustment.
If you’re looking for a fully pre-cut, ready-to-assemble pergola, our Apex Pergola range offers both overhang and no-overhang options for easier installation.

If a waterproof membrane is ordered, it will be supplied pre-cut to match the size of your pergola roof.

This pergola is not designed to be installed as a freestanding structure. For safety and long-term stability, it must be securely fixed into the ground using one of the recommended fixing options.
