Important installation information

This 4-Pitch Pergola kit is intentionally semi-custom. Certain components such as featheredge boards, tongue & groove boards, and battens require cutting to size during installation. This allows greater flexibility on-site and ensures the pergola can be accurately tailored to your specific layout.

If you are looking for a fully pre-cut, ready-to-assemble pergola, we recommend choosing one of our Apex Pergola options, including:

• Overhang Apex Pergola

• No-Overhang Apex Pergola

These alternatives arrive fully prepared for faster installation.

Ideal for outdoor living & entertaining

The open-roof 4-pitch design allows natural light, airflow, and outdoor ambience to flow freely beneath the structure. It’s an excellent choice for:

• Garden seating areas

• Outdoor dining spaces

• Hot tub enclosures

• Commercial or hospitality settings

Strong enough for practical use, refined enough to elevate any outdoor space.

Frequently Asked Questions

What is a 4 Pitch Pergola?

A 4 Pitch Pergola (also known as a 4-Point or 4-Sided Apex) features a roof with four sloping sides that meet at a central point, forming a cone-like shape. This design offers excellent visual balance and a more architectural appearance compared to standard pergola roofs.

What is the difference between an Apex Pergola and a 4 Pitch Apex Pergola?

An Apex Pergola has two sloping roof sides that meet in the middle to form an “A” shape.
A 4 Pitch Pergola has four roof slopes that all meet at a central peak, creating a more symmetrical, pavilion-style structure with a stronger visual presence.

Are the components pressure treated?

Yes. All timber components are pressure treated to protect against rot, decay, and insect attack. Roofing materials may vary depending on the option selected.

Do you make bespoke pergolas?

Yes, we manufacture fully bespoke pergolas. If you require custom dimensions or a tailored design, please contact our Sales team on 01409 231 763 or email sales@ruby-group.co.uk for a quotation.

Can I install a pergola without planning permission?

In most cases, pergolas can be installed under permitted development rights without planning permission. Rules can vary by location, so we strongly recommend checking with your local council before installation.

Installation FAQs

Does the pergola arrive fully assembled?

No. This pergola is supplied in kit form. Detailed installation manuals are provided to guide you through the build, making it suitable for competent DIY installers and professional fitters alike.

Please note: some components require cutting to size during installation to allow for a more precise, site-specific fit.

Are fixings included?

Yes. All required fixings are included as part of the pergola kit.

Aftercare & Maintenance FAQs

Can I paint my pergola?

Yes. You may use water-based paints only. Ensure the timber is completely dry before painting, and we recommend applying a UV-protective treatment first for best results.

What maintenance is required?

To maintain appearance and longevity, we recommend:

• Treating the pergola every 6 months with Osmo Oil or an equivalent product

• Periodically checking fixings and joints

• Removing any build-up of dirt or debris
