Dunster House Utopia Walled Garden Bar Gazebo | W4m x D3m | Fully Installed Nationwide

The Dunster House Utopia Walled Garden Bar Gazebo is the garden bar that does not need a wall to lean against. Freestanding, fully enclosed on all sides with 15mm tongue and groove walls, and complete with a solid timber log bar, this 4m x 3m structure is a self-contained outdoor bar that you can position anywhere in your garden — and that looks like it has always been there.

This is not an open-sided gazebo with a bar bolted on. The Utopia Walled Garden Bar is a proper enclosed structure with full timber walls on all sides, a 15mm tongue and groove roof deck, and a low-top log bar at 1.02m serving height that is included as standard. Supplied by Dunster House and fully installed by our in-house team at Bespoke Oak and Slate across the whole of Mainland UK, it arrives as a complete, ready-to-use garden bar. Foundations, shingles, Smart Seal timber treatment, all fixings — everything included, everything handled by our own team.

Fully Enclosed, Fully Finished

What makes the Utopia Walled Garden Bar different from every other garden bar gazebo on the market is the walls. Full 15mm tongue and groove timber walls on all sides give the structure the feel of a proper garden building rather than a covered outdoor area. The walls provide natural shelter from wind and rain, create a defined interior space that feels genuinely enclosed, and give you a surface on every side for shelving, lighting, signage, and bar back styling.

The included log bar — 1.44m wide, 0.56m deep, and 1.02m high — is a solid timber feature that you can finish however you like. Sand it, oil it, stain it, paint it — it is your bar, and it is built to be personalised. The 70mm x 70mm uprights frame the space with the same chunky, solid character that runs through the entire Utopia range.

Pressure Treated, Smart Sealed, Built for the Long Term

Every piece of timber in the Utopia Walled Garden Bar is slow grown spruce — denser and more stable than fast grown alternatives — and pressure treated at the factory through to the core, not just dip treated on the surface. That gives you a 10-year guarantee against rot and insect infestation and a structure that will still be standing and looking good a decade from now.

Once our team completes the installation, all exposed timber is finished with Smart Seal — a premium timber sealant that locks in the pressure treatment, repels moisture, and keeps the structure looking sharp year after year with minimal maintenance.

Frequently Asked Questions

Yes — the Utopia Walled Garden Bar Gazebo is a Dunster House product, supplied by Dunster House and fully installed by Bespoke Oak and Slate. You get the quality and guarantee of a Dunster House structure with the peace of mind of a complete, professional installation service.

What makes this different from an open-sided gazebo bar?

The Utopia Walled Garden Bar has full 15mm tongue and groove timber walls on all sides, making it a genuinely enclosed structure rather than a covered outdoor area. The walls provide wind and rain shelter, create a defined interior space, and give you surfaces on every side for shelving, lighting, and bar back styling. It feels more like a garden building than a gazebo.

What is the log bar like? Can I finish it myself?

The included log bar is a solid timber feature — 1.44m wide, 0.56m deep, and 1.02m high — supplied untreated so you can finish it exactly as you like. Sand it smooth, apply a natural oil, stain it to match your garden, or paint it to suit your style. It is a blank canvas that is built to be personalised.

What does full installation include?

Full installation includes foundation preparation, erection of the complete structure including all walls and the log bar, shingle roof supply and installation, Smart Seal timber treatment, and all fixings. We leave your garden clean and tidy with a structure that is ready to use from day one. No hidden extras, no separate groundworks quotes.

Do you install across the whole of the UK?

We install across the whole of Mainland UK — from Cornwall to Caithness. Our own in-house installation teams travel nationwide, so wherever your garden is, we can get there.

Can I upgrade the shingle roof to a slate finish?

Yes — you can upgrade to a Britmet composite slate roof for £1,500. Based on the roof area of 3.852m x 3.202m (12.33m²), this includes supply, full installation, and all associated flashings — a high-quality, low-maintenance finish that looks virtually identical to natural slate.

Can I add decking and lighting?

Yes to both. We can install a pressure treated timber deck beneath the full footprint (3.78m x 3.13m / 11.83m²) for £1,500, sealed with Smart Seal. Composite decking and full lighting installations are also available — contact us for pricing on both.

Does the structure need planning permission?

In most cases, a garden bar structure of this size falls within permitted development rights and does not require planning permission, provided it meets standard criteria around height, proximity to boundaries, and coverage of the garden. We recommend checking with your local planning authority if you have any specific concerns about your site.
