The back wall creates a defined rear to the structure, gives you a surface to mount shelving, bottle racks, a TV, or a bar back display, and adds a level of shelter and privacy that the open version simply cannot match.\u003c\/p\u003e\u003cp\u003eSpanning 6 metres wide and 3 metres deep with chunky 120mm x 120mm uprights and a built-in bar at 1.14m serving height, this is a structure that means business. Supplied by Dunster House and \u003cstrong\u003efully installed by our in-house team at Bespoke Oak and Slate\u003c\/strong\u003e across the \u003cstrong\u003ewhole of Mainland UK\u003c\/strong\u003e, it arrives as a complete, ready-to-use outdoor bar. Foundations, felt roof, Smart Seal timber treatment, all fixings — everything included, everything handled by our own team.\u003c\/p\u003e\u003ch2\u003eWhy the Back Wall Makes All the Difference\u003c\/h2\u003e\u003cp\u003eAn open gazebo bar is a fantastic entertaining space. A gazebo bar with a full back wall is something else entirely. The rear wall closes off the structure, giving it the feel of a proper outdoor room rather than a covered area. It provides natural wind shelter from the rear, making the space more comfortable in cooler weather. It gives you a blank canvas for bar back styling — shelves, mirrors, bottle displays, a mounted screen for sport — and it creates a visual backdrop that makes the whole bar look more considered and more permanent.\u003c\/p\u003e\u003cp\u003eFor anyone who wants their garden bar to look like it belongs rather than like it was added as an afterthought, the back wall version is the one to choose.\u003c\/p\u003e\u003ch2\u003eBuilt to the Same Uncompromising Standard\u003c\/h2\u003e\u003cp\u003eLike every structure in the Leviathan range, this version is built from pressure treated spruce with 120mm x 120mm uprights — among the chunkiest posts in the Dunster House range — and a 19mm tongue and groove roof deck that provides a solid, weathertight base for the felt roof included as standard. At 3.04m overall height with 2.12m of internal eaves clearance, there is genuine headroom throughout the full 6m width of the bar.\u003c\/p\u003e\u003cp\u003eEvery piece of timber is pressure treated at the factory — not dip treated, but properly pressure treated through to the core — and backed by a \u003cstrong\u003e10-year guarantee against rot and insect infestation\u003c\/strong\u003e. Once our team completes the installation, all exposed timber is finished with \u003cstrong\u003eSmart Seal\u003c\/strong\u003e, a premium sealant that locks in the treatment, repels moisture, and keeps the structure looking sharp year after year.\u003c\/p\u003e\u003ch2\u003eInstalled by Our Own Team, Nationwide\u003c\/h2\u003e\u003cp\u003eWe install garden structures across the whole of Mainland UK using our own in-house teams — not subcontractors, not agency labour, but experienced installers who take pride in every job they complete.

The open Leviathan has no rear wall, giving a more open, airy feel. The back wall version creates a more enclosed, sheltered space with a defined rear surface for bar back styling, shelving, screens, and displays — and provides additional wind shelter from the rear.\u003c\/p\u003e\u003ch3\u003eIs this a Dunster House product?\u003c\/h3\u003e\u003cp\u003eYes — the Leviathan Garden Bar Gazebo with Back Wall is a Dunster House product, supplied by Dunster House and fully installed by Bespoke Oak and Slate.

This includes supply, full installation, and all associated flashings.
