Forest Ultima Wooden Garden Pergola Arch 6’x4’

Overview

The Forest Ultima wooden garden pergola arch is a smart, well-proportioned archway for framing a path or garden gateway without overwhelming a smaller plot. At 6′ x 4′, priced at £419.99 and reduced to £260.99, it sits at the more compact end of the Ultima arch range.

Standing at 6′ x 4′, this wooden garden arch is built from pressure treated timber and designed to frame a path, gateway or the entrance to a seating area. Its slightly narrower stance makes it a good fit for standard garden path widths, while still leaving plenty of lattice for climbing plants to take hold.

Key Features

• Pressure treated timber for long-lasting outdoor use
• Open lattice sides ideal for training climbing plants
• Simple two-post design that is quick to install
• Pre-cut, pre-drilled components for straightforward assembly
• A natural focal point for borders, paths and garden entrances

Roof Types

As a garden arch rather than a shed, this structure does not have a solid roof panel. Instead, the top of the arch is formed from an open wooden lattice that climbing plants such as roses, clematis or honeysuckle can grow through, creating natural shade and cover once established rather than a fixed waterproof roof.

Dimensions

• Overall size: 6′ x 4′ (approx. 1.83m x 1.22m)
• Open lattice panels on both sides for training plants
• Ground spikes or post supports included for a secure fixing
• Lightweight enough for one person to position before fixing

Construction

The arch is built from pressure treated timber battens, jointed into a simple two-post frame with a lattice top and sides. Pressure treatment forces preservative into the wood fibres rather than coating the surface, helping the arch stand up to UK weather without immediate re-treatment.

Treatment & Guarantee

Because the timber is pressure treated at the factory, no additional preservative is needed before installing the arch. An occasional coat of timber treatment or stain will keep its appearance fresh over time, though this is a cosmetic choice rather than a requirement.

Doors & Windows / Security

As an open garden arch rather than an enclosed structure, this product has no doors, windows or lock. It is designed as a decorative, walk-through feature rather than a storage building.

Assembly Information

The arch is supplied flat packed with pre-cut, pre-drilled timber sections, fixings and step-by-step instructions. One person can usually assemble and position it within an hour or two, though a second pair of hands helps when fixing it into the ground.

Delivery Information

Delivery is made as a boxed flat pack parcel, light enough for one person to carry into the garden. Check the contents against the parts list before starting assembly in case of transit damage.

Optional Upgrades

Ground spikes or metal post supports can be added if fixing the arch into soil rather than a hard surface, and a matching timber bench or extra trellis panels can be bought separately to extend the feature.

Frequently Asked Questions

Do I need to treat the timber first? No, it is pressure treated at the factory and ready to install straight out of the box.

Can I grow climbing plants on it? Yes, the open lattice sides and top are designed for training climbers such as roses or clematis.

How is it fixed into the ground? Using ground spikes for soil, or post supports for a hard surface, depending on where you are positioning it.
