Why Firewood Deserves Better Than a Pile Under a Tarp

Everyone starts the same way: a heap of logs dumped beside the cabin, a tarp thrown over the top, and a vague plan to sort it out later. Six months on, the bottom layer is black with mould, the tarp has pooled water in the middle, and the wood hisses and smoulders when you finally get it on the stove. Wet wood wastes energy, soots up your flue, and gives you a fraction of the heat for twice the smoke.

Firewood at 20 per cent moisture content or below burns hot and clean. Firewood at 40 per cent fights you every step of the way. A simple raised, covered log store built against the side of your garden cabin solves the problem properly, and it takes a weekend to build and costs very little if you use what you have.

Pick the Right Spot Along the Cabin Wall

The practical spot is the side of the cabin that catches sun and prevailing wind, ideally the one you walk past on the way in. Airflow does the drying, sunlight does the rest, and convenience means you will actually keep it tidy.

• Leave a gap of at least 50mm between the store and the cabin wall. Direct contact traps damp, encourages woodworm, and makes any future cabin maintenance awkward.
• Stay clear of doors and windows. You want a clear path, and you do not want spiders and woodlice making the short journey indoors.
• Think about fire risk. Keep the store at least a metre from any flue outlet, stove vent, or outside socket, and never place it under a cabin window you might use as an escape route.
• Use the cabin roof overhang if you have one — it is free shelter — but do not rely on it alone. Driving rain comes in sideways.

Build a Raised Base With Air Underneath

Ground contact is the enemy. It wicks moisture up through the bottom logs, which is why the lowest layer of a ground-stacked pile is always the worst. Get the timber up and let air move underneath.

A simple frame of pressure-treated 75mm x 50mm timber, sitting on concrete pavers or bricks rather than bare soil or grass, works well. Set the base at least 150mm above ground level. If you want the fastest and cheapest version, two good wooden pallets on bricks will do the job, though treated timber lasts longer.

On top of the base, lay a floor of slatted battens with 20-25mm gaps between them. Do not use solid plywood or OSB as a floor — it blocks the drying air and rots quickly.

Keep the Rain Off, Keep the Air Moving

This is where most home-built stores go wrong. People build a sealed wooden box with a lid, and the wood inside sweats. The rule is simple: roof over, sides open.

• Slope the roof backwards or to one side so water runs off away from the cabin.
• Overhang the roof by at least 150mm on all open sides to stop rain blowing in.
• Leave the sides as open slats with 25mm gaps, or leave one long side completely open.
• Fix a back panel if the store faces the prevailing wind — in most of the UK that means the south-west — but keep the front and one end open.
• Never wrap it in plastic sheeting. A breathable tarp over the top of an open-sided store is fine; sealed plastic turns it into a compost bin.

Stacking, Seasoning and Knowing When Wood Is Ready

Split logs season far faster than whole rounds, so split anything over about 100mm across before it goes in. Stack the pieces bark down or on their sides with the cut ends facing the open side of the store. Air travels along the grain and out through the ends, so exposed ends dry quickest.

Leave small gaps between logs, but do not fuss — a slightly random, loosely packed stack dries better than a perfect jigsaw. Do not stack higher than about 1.2m without bracing, and keep the top layer covered or capped with a board.

Softwoods like pine and spruce are usually ready in 9 to 12 months. Most hardwoods need 12 to 18 months, and oak or dense species can take two years. Ash is the standout exception and seasons remarkably quickly. If you want certainty, buy a cheap moisture meter and split a log to test the inside: under 20 per cent is ready, under 15 per cent is excellent. Knock two logs together — a dry log rings, a wet one thuds.

A Year of Easy Cabin Living

Once the store is up, keep it working for you. Rotate your stock so older wood sits nearest the cabin door and new deliveries go to the far end. Use the dry store as your working supply in winter and keep a smaller basket inside — but only a few days' worth, as indoor heat dries wood too fast and can crack it.

In spring, clear out the crumbs and bark from the base, check the battens for rot, and sweep any debris off the roof. Refill over summer so the wood has the warm months to finish seasoning. A well-built log store beside your garden cabin is one of those quiet jobs that pays you back every cold evening: cleaner burns, more heat, less smoke, and a stack of dry logs that makes the whole place feel properly lived in.
