At \u003cstrong\u003e12 m³\u003c\/strong\u003e it takes a full bench run down each side with room to lie down on the upper level — not perch. Six people fit without anyone straddling the stove.

It is the more affordable build, and it needs treating and re-treating to stay looking new outdoors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThermowood\u003c\/strong\u003e is timber kiln-treated at 180–220°C in a low-oxygen chamber. That is not a surface coating. It changes the wood itself, closing the cells so it absorbs far less moisture — which is what stops outdoor timber cupping, twisting and splitting through a British winter. No chemical preservatives are involved. It arrives a deep honey-brown and weathers to a stable silver.\u003c\/p\u003e\n\u003cp\u003eOn a barrel this size the thermowood upgrade is worth thinking about carefully: there is simply more timber exposed to the weather, so there is more to gain from it.\u003c\/p\u003e\n\u003cp\u003eChoose your timber above.
