Frequently Asked Questions

What are the slatted back panels?

The slatted back panels are integrated timber slat walls fitted to the rear sections of the pergola. They create a sense of enclosure and privacy while still allowing light and air to pass through freely — perfect for defining your outdoor space without it feeling closed in. They also make an excellent frame for climbing plants.

How is this different from the standard Utopia Diamond Corner Pergola?

The Slatted Wall version includes built-in slatted back panels as part of the structure, giving greater privacy and a more enclosed, room-like feel compared to the open-sided standard model. The roof design, dimensions, and timber specification are otherwise identical.

Is the Utopia Slatted Wall Diamond Corner Pergola pressure treated?

Yes. All timber is fully factory pressure treated against rot, decay, and insect damage. It arrives ready to install with no need for immediate staining or treatment.

Yes — professional installation is included as standard with every order. Our experienced fitting teams cover the whole of Mainland UK, handling delivery and full assembly so your pergola is ready to enjoy from day one.

Do you install anywhere in the UK?

Does this pergola need planning permission?

In most cases, a pergola of this size falls within permitted development rights and does not require planning permission, provided it meets standard conditions (e.g. not covering more than 50% of garden area, not forward of the principal elevation). We always recommend checking with your local planning authority if you are unsure.

What is the pergola made from?

The Utopia Slatted Wall Diamond is a Dunster House product, constructed from slow-grown spruce — a dense, strong timber well-suited to outdoor use. All timber is fully pressure treated for long-term durability in the British climate.

How thick are the posts?

The upright posts are 70mm x 70mm, providing excellent structural rigidity and a premium, substantial appearance.

What are the exact dimensions?

The overall external footprint is 3.321m x 3.321m (approx. 10' 10.75" x 10' 10.75"), with an internal usable space of 2.92m x 2.92m. The overall height is 2.15m with an internal eaves height of 1.973m. All sizes are nominal.

Is this pergola suitable for a corner of my garden?

Yes — the Utopia Slatted Wall Diamond is specifically designed as a corner pergola, fitting neatly into the corner of a garden, patio, or decking area to maximise your available outdoor space.

How long will delivery and installation take?

Lead times vary depending on your location and current demand. Please contact us directly for an accurate delivery and installation timeline for your area.
